HV580L Series Frequency Inverter. User Manual (Version: 3.1.14) - page 5

The output frequency increases or decreases along the S curve. This mode is generally used in the

applications where start and stop processes are relatively smooth, such as elevator and conveyor belt. P6-08

and P6-09 respectively define the time proportions of the start segment and the end segment.

• 2: S-curve acceleration/deceleration B

In this curve, the rated motor frequency fb is always the inflexion point. This mode is usually used in

applications where acceleration/deceleration is required at the speed higher than the rated frequency.

When the set frequency is higher than the rated frequency, the acceleration/deceleration time is:

In the formula, f is the set frequency, fb is the rated motor frequency and T is the acceleration time from 0 Hz

to fb.

These two parameters respectively define the time proportions of the start segment and the end segment of

S-curve acceleration/deceleration. They must satisfy the requirement: P6-08 + P6-09 ≤ 100.0%.

In Figure 6-11, t1 is the time defined in P6-08, within which the slope of the output frequency change

increases gradually. t2 is the time defined in P6-09, within which the slope of the output frequency change

gradually decreases to 0. Within the time between t1 and t2, the slope of the output frequency change remains

unchanged, that is, linear acceleration/deceleration.

P6-11 (Initial frequency of stop DC braking)

During the process of decelerating to stop, the AC drive starts DC braking when the running frequency is lower

than the value set in P6-11.

P6-12 (Waiting time of stop DC braking)

When the running frequency decreases to the initial frequency of stop DC braking, the AC drive stops output

for a certain period and then starts DC braking. This prevents faults such as overcurrent caused due to DC

braking at high speed.

P6-13 (Stop DC braking current)

126

This parameter specifies the output current at DC braking and is a percentage relative to the base value.

- If the rated motor current is less than or equal to 80% of the rated AC drive current, the base value is the

rated motor current.

- If the rated motor current is greater than 80% of the rated AC drive current, the base value is 80% of the

rated AC drive current.

P6-14 (Stop DC braking time)

This parameter specifies the holding time of DC braking. If it is set to 0, DC braking is cancelled.

P7-12 is used to set the number of decimal places for load speed display. The following gives an example to

explain how to calculate the load speed:

Assume that P7-06 (Load speed display coefficient) is 2.000 and P7-12 is 2 (2 decimal places). When the

running frequency of the AC drive is 40.00 Hz, the load speed is 40.00 x 2.000 = 80.00 (display of 2 decimal

places).

If the AC drive is in the stop state, the load speed is the speed corresponding to the set frequency, namely,

"set load speed". If the set frequency is 50.00 Hz, the load speed in the stop state is 50.00 x 2.000 = 100.00

(display of 2 decimal places).

If the set frequency is within the frequency jump range, the actual running frequency is the jump frequency close

to the set frequency. Setting the jump frequency helps to avoid the mechanical resonance point of the load.

The HV580L supports two jump frequencies. If both are set to 0, the frequency jump function is disabled. The

principle of the jump frequencies and jump amplitude is shown in the following figure.

P8-15

Setting Range

0.00Hz ～ 10.00Hz

This function is used for balancing the workload allocation when multiple motors are used to drive the same

load. The output frequency of the AC drives decreases as the load increases. You can reduce the workload of

the motor under load by decreasing the output frequency for this motor, implementing workload balancing

between multiple motors.

Accumulative power-on time threshold

Default

0h

P8-16

Setting Range

0h ～ 65000h

If the accumulative power-on time (P7-13) reaches the value set in this parameter, the corresponding DO

terminal becomes ON.

For example, combining virtual DI/DO functions, to implement the function that the AC drive reports an alarm

when the actual accumulative power-on time reaches the threshold of 100 hours, perform the setting as

follows:

1) Set virtual X1 to user-defined fault 1: A1-00 = 44.

2) Set that the valid state of virtual X1 is from virtual DO1: A1-05 = 0000.

3) Set virtual DO1 to power-on time reached: A1-11= 24.

4) Set the accumulative power-on time threshold to 100 h: P8-16 = 100 h.

Then, the AC drive reports Err27 when the accumulative power-on time reaches 100 hours.

Accumulative running time threshold

Default

0h

P8-17

Setting Range

0h ～ 65000h

It is used to set the accumulative running time threshold of the AC drive. If the accumulative running time

(P7-09) reaches the value set in this parameter, the corresponding DO terminal becomes ON.

This parameter is used to set whether to enable the safety protection. If it is set to 1, the AC drive does not

respond to the run command valid upon AC drive power-on (for example, an input terminal is ON before

134

power-on). The AC drive responds only after the run command is cancelled and becomes valid again.

In addition, the AC drive does not respond to the run command valid upon fault reset of the AC drive. The run

protection can be disabled only after the run command is cancelled.

In this way, the motor can be protected from responding to run commands upon power-on or fault reset in

unexpected conditions.

running frequency is lower than value of P8-19, the DO terminal goes OFF

These two parameters are respectively used to set the detection value of output frequency and hysteresis

value upon cancellation of the output. The value of P8-20 is a percentage of the hysteresis frequency to the

During acceleration, if the running frequency is smaller than the value of P8-25, acceleration time 2 is selected.

If the running frequency is larger than the value of P8-25, acceleration time 1 is selected.

During deceleration, if the running frequency is larger than the value of P8-26, deceleration time 1 is selected.

If the running frequency is smaller than the value of P8-26, deceleration time 2 is selected.

P8-52

Setting Range

0.0s ～ 6500.0s

These parameters are used to implement the dormant and wakeup functions in the water supply application.

When the AC drive is in running state, the AC drive enters the dormant state and stops automatically after the

dormant delay time (P8-52) if the set frequency is lower than or equal to the dormant frequency (P8-51).

When the AC drive is in dormant state and the current running command is effective, the AC drives starts up

after the wakeup delay time (P8-50) if the set frequency is higher than or equal to the wakeup frequency

(P8-49).

Generally, set the wakeup frequency equal to or higher than the dormant frequency. If the wakeup frequency

and dormant frequency are set to 0, the dormant and wakeup functions are disabled.

When the dormant function is enabled, if the frequency source is PID, whether PID operation is performed in

the dormant state is determined by PA-28. In this case, select PID operation enabled in the stop state (PA-28

= 1).

P9-00 = 0

The motor overload protective function is disabled. The motor is exposed to potential damage due to

overheating. A thermal relay is suggested to be installed between the AC drive and the motor.

144

P9-00 = 1

The AC drive judges whether the motor is overloaded according to the inverse time-lag curve of the motor

overload protection.

The inverse time-lag curve of the motor overload protection is:

220% x P9-01 x rated motor current (if the load remains at this value for one minute, the AC drive reports

motor overload fault), or 150% x P9-01 x rated motor current (if the load remains at this value for 60 minutes,

the AC drive reports motor overload fault)

Set P9-01 properly based on the actual overload capacity. If the value of P9-01 is set too large, damage to the

motor may result because the motor overheats but the AC drive does not report the alarm.

Motor overload warning coefficient

Default

80%

P9-02

Setting Range

50% ～ 100%

This function is used to give a warning signal to the control system via DO before motor overload rotection.

This parameter is used to determine the percentage, at which pre-warning is performed before motor overload.

The larger the value is, the less advanced the pre-warning will be.

When the accumulative output current of the AC drive is greater than the value of the overload inverse

time-lag curve multiplied by P9-02, the DO terminal on the AC drive allocated with function 6 (Motor overload

pre-warning) becomes ON.

Overvoltage stall gain

Setting Range

0 (no stall overvoltage)～ 100

Overvoltage stall protective voltage

Default

130%

P9-04

Setting Range

120% ～ 150%

When the DC bus voltage exceeds the value of P9-04 (Overvoltage stall protective voltage) during

deceleration of the AC drive, the AC drive stops deceleration and keeps the present running frequency. After

the bus voltage declines, the AC drive continues to decelerate.

P9-03 (Overvoltage stall gain) is used to adjust the overvoltage suppression capacity of the AC drive. The

larger the value is, the greater the overvoltage suppression capacity will be.

In the prerequisite of no overvoltage occurrence, set P9-03 to a small value. For small-inertia load, the value

should be small. Otherwise, the system dynamic response will be slow. For large-inertia load, the value should

be large. Otherwise, the suppression result will be poor and an overvoltage fault may occur.

If the overvoltage stall gain is set to 0, the overvoltage stall function is disabled.

P9-06

Setting Range

100% ～ 200%

When the output current exceeds the overcurrent stall protective current during acceleration/deceleration of

the AC drive, the AC drive stops acceleration/deceleration and keeps the present running frequency. After the

output current declines, the AC drive continues to accelerate/decelerate.

P9-05 (Overcurrent stall gain) is used to adjust the overcurrent suppression capacity of the AC drive. The

larger the value is, the greater the overcurrent suppression capacity will be. In the prerequisite of no

overcurrent occurrence, set P9-05 to a small value.

For small-inertia load, the value should be small. Otherwise, the system dynamic response will be slow. For

large-inertia load, the value should be large. Otherwise, the suppression result will be poor and overcurrent

fault may occur.

If the overcurrent stall gain is set to 0, the overcurrent stall function is disabled.

Upon instantaneous power failure or sudden voltage dip, the DC bus voltage of the AC drive reduces. This

function enables the AC drive to compensate the DC bus voltage reduction with the load feedback energy by

reducing the output frequency so as to keep the AC drive running continuously.

• If P9-59 = 1, upon instantaneous power failure or sudden voltage dip, the AC drive decelerates. Once the

bus voltage resumes to normal, the AC drive accelerates to the set frequency. If the bus voltage remains

normal for the time exceeding the value set in P9-61, it is considered that the bus voltage resumes to normal.

152

• If P9-59 = 2, upon instantaneous power failure or sudden voltage dip, the AC drive decelerates to stop.

Group PA: Process Control PID Function

PID control is a general process control method. By performing proportional, integral and differential

operations on the difference between the feedback signal and the target signal, it adjusts the output frequency

and constitutes a feedback system to stabilize the controlled counter around the target value.

It is applied to process control such as flow control, pressure control and temperature control. The following

figure shows the principle block diagram of PID control.
