Positive action: If the feedback signal is smaller than the PID reference signal, it is required to boost
the output frequency of the inverter to make PID reach balance. The winding tension PID control is such a
case.
Negative action : If the feedback signal is smaller than the PID reference signal, it is required to
decrease the output frequency of the inverter to make PID reach balance.The unwinding tension PID
control is such a case.

☆
PID reference feedback range is a dimensionless unit which is used to display U0.15 PID setup and
U0.16 PID feedback.
PID reference feedback related to the value 100.0%, corresponding to a given feedback range FA.04.If
FA.40 is set to 2000,PID is set to 100.0%,PID given display U0.15 is 2000.

Proportional gain KF1 : the parameter determines the adjustable strength of PID regulator. The larger
P is, the greater the adjustable strength will be.When the parameter is set to 100.0, it means that when the
deviation between PID feedback value and reference value is 100.0%, the range for the PID regulator to
regulate the output frequency commands is the maximum frequency (integration effect and differential
effect are omitted).
Integration time Ti1 :determines the strength of PID integration regulation. The shorter the integration
time , the greater adjustable strength will be.Integration time means that when the deviation between PID
feedback value and reference value is 100%, the adjustment by the integration regulator (proportional
effect and differential effect are omitted) after continuous adjustment in this period reaches the maximum
frequency.
Differential time Td1 : determines the degree of adjustment that PID regulator performs on the
derivation between PID feedback value and reference value.Differential time means that if the feedback
value changes100% within this time, the adjustment by the differential regulator (proportional effect and
differential effect are omitted) will reach the maximum frequency.The longer differential time is, the higher
the degree of adjustment will be.

☆
It is used to set the maximum allowable deviation between the system feedback value and reference
value. When the deviation between the PID feedback and reference is within this range, the PID stops
adjustment. The deviation limit is calculated according to the percentage of the PID setup source (or
feedback source).When deviation between reference value and the feedback value is small,output
frequency is stability constant.It’s especially effective for some closed loop control occasions.

In some applications, one group of PID parameters can not meet the needs of the whole operation
process. Different parameters are used for different situations.
This group of function codes is used to switch 2 groups of PID parameters. Regulator parameters
FA.15~FA.17 and parameter FA.05~FA.07 have the same setting method.
Two groups of PID parameters can be switched through multi-function digital DI terminal as well as
PID deviation auto switching.
FA.18=1 : Set multi-function terminal to 43(PID parameter switching terminal). Choose parameter
group 1(FA.05~FA.07) when terminal invalid,while valid please choose parameter group 2 (FA.15~FA.17).
FA.18=2 : When deviation absolute value between reference and feedback is less than FA.19 set
value, PID parameters select parameter group 1. When deviation absolute value between reference and
feedback is greater than FA.20 set value, PID parameters select group 2. When deviation absolute value
between reference and feedback is within the range of switching deviation 1 &2 , PID parameters select
linear interpolation value of the 2 PID parameter groups.As shown in 5-26.

5.13 Swing frequency, fixed length and counting:Fb.00-Fb.09
The swing frequency function is applicable to textile and chemical fiber industries and
applications where traversing and winding functions are required.
Swing frequency means that the inverter output frequency swings up and down with the
setup frequency as the center, and the trace of running frequency at the time axis is as shown in
Fig. 5-28.The swing amplitude is set by Fb.00 and Fb.01.
When Fb.01 is set to 0, it means the swing amplitude is 0, and the swing frequency is invalid.

Multi-function digit DI terminal of HV610C is equipped with two functions relating torque control :
Torque control banned(Function29), speed control/torque control switching (function 46). The two terminals
should be matched with A0.00 to realize switching between speed control and torque control.
A0.00 set the control mode when speed/torque control switching terminal invalid. If the speed/torque
control switching terminal is valid, control mode is equivalent to the inversion of A0.00 value.
When function 29 is valid, speed control mode is fixed for the inverter .

In torque control mode , rate of speed change of motor and load is decided by the difference
between motor output toque and load torque. Therefore, motor speed may change fast, causing noise
or excessive mechanical stress problems. By setting the torque control acc./dec. time, can make the
motor speed changes smoothly.
A0.07 and A0.08 should be set to 0.00s in situations where torque rapid response is needed.
E.g:Two motors drive the same load, to make sure of load uniform distribution , one is set as host
inverter(speed control mode) and another is the slave one(torque control mode). Actual output torque of
the host inverter is the torque command of the slave, and slave torque is required to quickly follow the
host torque, then torque control acc./dec. time is set to 0.00s for the slave inverter.

State of virtual VDI terminal can be set through 2 setting methods, which is different from common
digit input terminals, and select through A1.05.
When choosing the corresponding VDO state as the decision of VDI state , valid state of VDI is
depending on VDO output as valid or not. VDIx only binding VDOx( x :1~5).
Binary bits of function code A1.06 decide vitual input terminal states respectively.
105
Section V. Parameter Function Table
The following example illustrates the method of using virtual VDI.
E.g1 : When choosing VDO state deciding VDI state, to complete “AI1 input exceeding limit,
inverter fault alarm and stop”:
Set VX1 to “ user-defined fault 1”(A1.00=44);
Set VDO (A1.05=xxx0) to decide VX1 terminal valid state;
Set VDO output function to “AI1 excessive input”(A1.11=31);
When AI1 exceeding the upper / lower limit , VDO output ON signal, VX1 input terminal state is
valid, VX1 receives “ user-defined fault 1”, and inverter fault alarm and stop , fault No. 27= E.USt1.
E.g2 : When choosing function code A1.06 deciding VDI state, to complete “ Auto into running
state after power-on ”:
Set VX1 to “Forward command FWD”(A1.00=1);
Set function code (A1.05=xxx1) to decide VX1 terminal valid state;
Set VX1 termianl to valid state(A1.06=xxx1);
Set command source to “Terminal control”(F0.02=1);
Set startup protection selection to invalid state.( F8.18=0);
After inverter power-on and the initialization, VX1 is detected as valid, the terminal corresponding
to forward running, which is equivalent to inverter receiving a forward running command, and then start
forward running.

A5.00 is only valid for VF control mode. In asynchronous motor VF running mode, square wave
determine the continuous modulation mode. Wave value < A5.00 : 7-stage continuous modulation
mode. Wave value>A5.00:5-stage continuous modulation mode.
In 7-stage continuous modulation mode, inverter switch loss is relatively big, but current ripple is
small. In 5-stage continuous modulation mode, inverter switch loss is relatively small, but current ripple
is big. High frequency may lead to motor operation instability, generally there is no need of modification.
For VF operation instability please refer to F3.11. For inverter loss and temperature rise please

This parameter is only valid for VF control mode. Asynchronous modulation refers to carrier
frequency that linear changes with output frequency, and ensure that the ratio of them (carrier ratio)
remains the same. Generally high output frequency is benefit for output voltage quality.
Generally, synchronous modulation is not needed at low frequencies ( below 100Hz), because the
ratio of carrier frequency and output frequency is relatively high,asynchronous modulation advantage is
more obvious.
When running frequency is greater than 85Hz, synchronous modulation is valid. And fixed as

Section V. Parameter Function Table
Analog input AI1~AI3 of HV610C are all provided with hopping function for set value.
Hopping frequency refers to fixing of analog corresponding setup to the value of hopping point
when analog corresponding setting varies within jump point upper/lower limit.
E.g:
Voltage of analog input AI1 is in 5.00V fluctuation, which range is 4.90V~5.10V. Minimum input
0.00V corresponding to 0.0%, while maximum input 10.00V corresponding to 100.%.The corresponding
setting of AI1 fluctuates between 49.0%~51.0%.
Set A5.16 to 50.0% and A5.17 to 1.0%, after hopping function processing, AI1 is fixed as 50.0%. In
this way, AI1 is converted into a stable input, and fluctuation is eliminated.
