IPE300 series engineering VFD Basic operation guidelines
-57-
function code, the current closed-loop control in the
IF control mode is enabled;
and when the frequency is higher than that, the
current closed-loop control in the IF control mode is
disabled.
Setting range: 0.00–20.00 Hz
Enabling IF mode for
AM 2
Current setting in IF
mode for AM 2
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%
Proportional
coefficient in IF mode
for AM 2
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 coefficient in
IF mode for AM 2
When IF control is adopted for AM 2, the function
code is used to set the integral coefficient of output
current closed-loop control. Setting range: 0–5000
Frequency threshold
for switching off IF
mode for AM 2
When IF control is adopted for AM 2, the function
code is used to set the frequency threshold for
switching off the output current closed-loop control.
When the frequency is lower than the value of the
function code, the current closed-loop control in the
IF control mode is enabled;
and when the frequency is higher than that, the
current closed-loop control in the IF control mode is
disabled.
Setting range: 0.00–20.00 Hz
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.
