Detailed parameter description
Default
value
P04.47
Proportional
coefficient in IF mode
for asynchronous
motor 2
When IF control is adopted for asynchronous motor
2, this parameter is used to set the proportional
coefficient of the output current closed-loop control.
Setting range: 0–5000
650
P04.48
Integral coefficient in
IF mode for
asynchronous motor 2
When IF control is adopted for asynchronous motor
2, this parameter is used to set the integral
coefficient of the output current closed-loop control.
Setting range: 0–5000
350
P04.49
Frequency threshold
for switching off IF
mode for
asynchronous motor 2
When IF control is adopted for asynchronous motor
2, this parameter 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 this parameter, 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
10.00Hz
5.5.5 Torque control
The TD350 VFD supports torque control and speed control. Speed control mode 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 torque limit. Torque control mode aims to stabilize the torque to
keep the set torque consistent with the actual output torque, meanwhile, the output frequency is
restricted by upper/lower limit.
