P2.29REV prohibited

Setting range: 0, 1

When P2.29=0, this function is disabled. In this case, terminal F/R=OFF, Run FWD; terminal F/R=ON,

Run Rev;

When P2.29=1, this function is enabled. In this case, terminal F/R signal is invaid. Mtor can only run

forward, and switching between FWD/REV is not available.

Running mode of routine program is independent of this function.

In traverse operation mode, both FWD and REV running are allowable, but switching between

FWD/REV is prohibited. Setting FWD/REV direction may not be same as actual direction, which can be

defined by changing phase sequence of the output.

P2.30Carrier frequency adjustment

Setting range:2.0～12.0KHz

Carrier wave frequency can be continuously adjusted within 2.0~12.0KHz.

This function is mainly used to improve system performance, and reduce noise and vibration.Since HV390

series adopts IGBT as power devices, carrier frequency can be higher. Increasing carrier frequency can

bring following benefits: better current waveform, lower noise, which is especially suitable for applications

that need low noise. However, with the increase of carrier frequency, it also brings some disadvantages,

such as increase of power loss on switching devices, overheat, low efficiency, etc. Since high frequency

carrier produces severeradio interference, please install filter for application with high requirement on EMI.

At the same time, capacitive leakage current increases, and the wrong action of leakage protector and over

current may happen.

Decreasing carrier frequency, the contrary is the case. Motor noise will increase in lower carrier frequency.

Influence of carrier frequency is different for various motors. Therefore, optimalcarrier frequency should be

selected according to practical situation. In fact, with the increase of motor capacity, carrier frequency should

decrease. For motor capacity above 37 kW, 2KHz carrier frequency is recommended.

P2.31Zero frequency threshold

Setting range: 0~600.0Hz

P2.32Zero frequency hysteresis

Setting range: 0~600.0Hz

The above two parameters are to set zerofrequency hysteresis control.

Take analog input AI1 for example, see Fig.6-10:

Startup process:

When the Run command is issued, only afterAI1voltage arrives or exceeds VS-b, does the drive start

andaccelerate to the preset frequency in defined Acc time.

Stop process:

During Dec process, when AI1voltage reduces to VS-b, thedrive will not stop until it reaches VS-a and

thecorresponding frequency becomes fa, where fa isthe threshold of zero frequency defined by P2.31, and

fb, fa is defined by P2.32.

This function can realize dormancy to saveenergy, in this way, frequent start and stop atthreshold frequency

can be avoided.

frequency corresponding to the rated output voltage UN. Its range is 10 to 600Hz. Generally, FBASE should

be selected according to rated frequency of the motor. In some special case, it can be selected according

to requirement. In this condition, both motor V/F characteristic and output torque should be considered.

Note:

Generally, factory setting (2%) can satisfy most applications. If over-current fault occurs during startup,

please increase this parameter from zero gradually until it meets requirement. Pay attention that large torque

boost could damage equipment.

P4.08 Slip compensation

Setting range：0.0～10%(Rated speed P3.04)

In V/F control mode, motor's speed will bedecreased with load rising. In order to ensurethe motor's

speed be close to synchronousspeed in rated load condition, slipcompensation can be done according to

thepreset frequency.

0: Disabled;

1: Enabled

AVR is auto voltage regulation. When theinverter's input voltage differs with the ratedinput voltage, the

inverter's output voltage canbe stablized by adjusting the width of PWMwave.

This function is disabled when the outputvoltage is higher than input voltage.

If the integral time is set to 0 (P5.01=0, P5.03=0), which means integral function is disabled, and the

speed loop is simply a proportion regulator.

b.Adjustment of proportion gain P andintegration time I for speed regulator

Increasing P will fasten system transient response, but system oscillation may occur given too big

P.Decreasing I will fasten transient response, but system oscillation and overshoot may occur given too

small.

Normally, user may tune P first, increase its value as long as no system oscillation occurs; then adjust I,

ensuring fast response without overshoot. Figure 6-15 shows better speed step response if P, I are set

properly. Speed response can be monitored through analog terminals AO1 and AO2. Refer to P8 parameter

group for detail information.

Fig. 6-15 Step response with better dynamic performance

Note:

With improper PI parameters, after accelerating to high speed, over-voltage during Dec process may

occur (Without external braking resistor or unit), which is caused by regenerative braking after speed

overshoot. To avoid this fault, user can tune PI parameters.

Adjustment of PI parameter in high/low speed applications

If system is required to respond quickly both in low and high frequency operation with load, user may

set ASR switching frequency (P5.04). Normally, when the system runs at low frequency, the transient

response performance can be improved by increasing P and decreasing I. Adjust ASR parameters following

the procedures below:

Set appropriate switching frequency P5.04;

Tune proportional gain P5.00 and integrationtime P5.01 for low-speed application, andensure no

oscillation and good response performance at low frequency.

Next, tune proportional gain P5.02 andintegration time P5.03 for high-speed application, and ensure

no oscillation and good response performance at high frequency.

P5.05 Slip compensation gain

Setting range:50.0～200.0%

P5.05 is used to calculate slip frequency. Setting value 100% means rated slip frequency corresponds

to rated torque current. User may decrease/increase the settings of P5.05 to adjust the speed control's

difference accurately.

Note:

This function is valid to open loop vector control mode. For close loop vector control mode, F5.05 can

be set to 100% for most applications.

This function is reserved.

P5.07 Driving torque lilmit

Setting range:0.0～200.0% (motor’s rated current)

P5.08 Braking torque limit

Setting range:0.0～200.0%(motor’s rated current)

Torque limiting is used to limit output torque current of speed regulator'.

Torque limit is the percentage of the motor’s rated current; If the torque limit is 100%, then the torque

current limit is the motor's rated current. P5.07 and P5.08 limit the output torque in driving state and braking

state respectively, which is shown in Figure 6-16.

If fault alarm occurs, user can reset the inverter by external terminal. This function is active at

rising edge of pulse signal. It has the same function as STOP/RESET key.

4~5: Terminal for external FWD/REV Jog running control.

In terminal control mode (P0.01=1), this terminal is used to select Jog operation.

6~9: Multi-frequency terminals

In multi-frequency operation mode, 4 digital input terminals should be defined as the control

terminals. Through the combination of ON/OFF state of the 4 terminals, up to 15 values can be

defined set as preset frequency. Refer to parameter P2.09~P2.23 for details.

10~11: Acc/Dec time terminals

By combination of the ON/OFF state of Acc/Dec time terminals, user can select Acc/ Dec time

1~4, refer to parameter P0.16,P0.17 and P2.00~P2.05 for more details. If this function is not

defined, Acc/Dec time 1 will be the default setting except in simple PLC operation mode.

12~13: Normally open terminal for externalfault

Fault signal of externalequipment can be input via the terminal, which isconvenient for the drive

to monitor the fault ofexternal equipment. Once the drive receives thefault signal, it will display

“Er11”. During normal stop process, this function is disabled. The fault signalhas two input

modes, i.e. normally open andnormallyclose.

14~15: Frequency increase/decease command

The running frequency can be set throughexternal terminals, thus the running frequencycan be

set remotely. At this time,P0.03 can beset to 2 or 3. When the terminal is ON, thefrequency

setting value is increased ordecreased at the rate defined by P6.01; when the terminal is OFF,

frequencysetting value keeps constant. When these twoterminals are ON at the same time,

frequencysetting value also keeps constant. Please referto P0.03 parameters description.

16: Free run to stop terminal (FRS)

When the function terminal is ON, inverter stops output immediately andenter stopping state,

the motor enters free run to stop state.

If F6.00=2 or 3, this terminal is defined as three-wire control terminal whenthree-wire control

mode is selected. If If F6.00=2 or 3, and none of DI1~DI5 is defined as three-wire control

terminal, the inverter will report parameter setting fault ERR4. In this case, user should define

“three-wire control terminal” first, and then define “three-wire control mode” (P6.00=2 or 3).

11. 18: Switching input signal

If analog setting mode is selected, (P0.09=4、5 or 6), this function is used to switch reference

isselected. Refer to Pb parameter group for details.

13.22: DC braking command

When the inverter is in Dec-to-stop process,and the running frequency is lower than initialfrequency of

DC injection braking defined in P1.06, this function is enabled. When theterminal is ON, DC injection

braking isperformed under braking voltage defined in P1.08. DC injection braking is ended onlywhen the

terminal is OFF.

When this function is enabled, parameters of DC injection braking time are invalid.

14. 23: Acc/Dec disabled command

When the terminal is ON, the invertertemporarily inhibits executing the Acc/Deccommand and runs at

current frequency. Whenthe terminal is OFF, normal Acc/Deccommands can be executed. If there is

anycontrol signal with higher priority input such asexternal fault signal, the inverter will exitAcc/Dec inhibit

state immediately and executespecified processing procedures.
