Learning Advanced Features
Depending on the duration of Instantaneous power interruptions and the amount of load inertia, a low
voltage trip may occur even during a kinetic energy buffering operation. Motors may vibrate during
kinetic energy buffering operation for some loads except variable torque load (for example, fan or
pump loads).
5.13 Torque Control
When the motor output torque is greater than the load, the speed of motor becomes too fast. To
prevent this, set the speed limit. (The torque control function cannot be used while the speed limit
function is running.)
The torque control function controls the motor to maintain the preset torque value. The motor
rotation speed maintains the speed constantly when the output torque and load torque of the
motor keep a balance. Therefore, the motor rotation speed is decided by the load when
controlling the torque.
