Group S1: Vector control
S1.00
Speed feedback proportional gain Factory default 1.000
Setting range 0.000 − 10.000 Minimum unit 0.001
S1.01
Speed feedback integral time Factory default 1.000s
Setting range
0.000 − 10.000s
(0.000 means inactive)
Minimum unit 0.001s
Used to adjust the speed dynamic response characteristics of vector control.
●
Larger proportional gain leads to faster response.
● Too large proportional gain may cause oscillation.
● Smaller proportional gain leads to slower response.
● Larger integral time leads to slower dynamic response of the system
and the control on external disturbance is slowed.
● Smaller integral time leads to faster dynamic response of the system.
● Excessively small integral time may cause oscillation.
If the factory defaults can not meet the application requirements, the parame‐
ters can be adjusted in the following manner:
●
The proportional gain should be increased without causing oscillation.
● The integral time should be decreased to allow the system to have quick
response and smaller overshoot.
Improperly set parameters may lead to excessive speed over‐
shoot or overvoltage faults during fall back from the overshoot.
S1.02
Torque limit Factory default 150.0 %
Setting range
0.0 % − 200.0 %
(of rated motor torque)
Minimum unit 0.1 %
Used to to limit the maximum torque current of the converter during startup or
braking.
If a large brake torque is required, apply the torque limit funcion
together with brake.
S1.03
Slip compensation gain Factory default 100.0 %
Setting range 0.0 % − 250.0 % Minimum unit 0.1 %
Used to maintain constant motor speeds with load changes.
Increase this value when the motor is heavily loaded and has a
low speed, and vice versa.
S1.04
Torque control selection Factory default 0
Setting range
0: Terminal control
1: Always active
Minimum unit 1
● 0: Terminal control
