Sensor-less vector control 2 and close-loop vector control support torque control. Under these two
control patterns, speed control and torque control can be programmed by this parameter.Added to this,
the switchover between speed control and torque control can also be realized by digital input terminal
"speed/torque control switch". The relation of the switchover via terminal and parameter is shown in
the following table:

Under speed control, output torque of motor will match load automatically. In order to avoid
overcurrent fault caused by excessive output torque, it is necessary to set appropriate torque limit
value and keep output torque of motor within this limit. Please refer to the specification of F10.10 for
torque limited information.
Under torque control, torque can be set by different sources, by F10.16. Under torque control,
motor speed is determined by the difference between set torque and load torque. When the set torque
is bigger than load torque, motor will be accelerated continuously. When the set torque is smaller than
load torque, motor will be decelerated continuously. When the set torque is matching load torque well,
the speed of motor will be maintained. Therefore, it is necessary to set limit value of forward or reverse
speed during torque control so as to prevent over-run caused by continuous acceleration of motor.
Please set the speed limits in F10.18

F10.19 under torque control.

Speed loop PI parameters vary with running frequencies of the AC drive.
If the running frequency is less than or equal to "Switchover frequency 1" (F10.03), the speed loop
PI parameters are F10.00 and F10.01.
If the running frequency is equal to or greater than "Switchover frequency 2" (F10.06), the speed
loop PI parameters are F10.04 and F10.05.
If the running frequency is between F10.03 and F10.03, the speed loop PI parameters are
obtained from the linear switchover between the two groups of PI parameters.
The speed dynamic response characteristics in vector control can be adjusted by setting
theproportional gain and integral time of the speed regulator.To achieve a faster system response,
increase the proportional gain and reduce the integral time. Be aware that this may lead to system
oscillation.
The recommended adjustment method is as follows:
If the factory setting cannot meet the requirements, make proper adjustment. Increase the
proportional gain first to ensure that the system does not oscillate, and then reduce the integral time to
ensure that the system has quick response and small overshoot.
ATTENTION:
Improper PI parameter setting may cause too large speed overshoot, and overvoltage fault may
even occur when the overshoot drops.
