5.5.5 Torque control

The VFD supports torque control and speed control. Speed control aims to stabilize the speed
to keep the set speed consistent with the actual running speed, meanwhile, the max.
load-carrying capacity is restricted by the torque limit. Torque control aims to stabilize the
torque to keep the set torque consistent with the actual output torque, meanwhile, the output
frequency is restricted by the upper and lower limits.
Name
When IF control is adopted for AM 2, the
function code is used to set the output current.
The value is a percentage in relative to the
rated current of the motor.
Setting range: 0.0–200.0%
When IF control is adopted for AM 2, the
function code is used to set the proportional
coefficient of output current closed-loop
control. Setting range: 0–5000
Integral
