Code Description
CON-11 Hold Time
When a run command stops, the inverter holds the zero speed output
for the set time before the motor decelerates to a complete stop.
8.14 Torque Control
You can use torque control to operate the inverter to produce a certain amount of torque as
indicated by the torque reference. In torque control mode, the motor speed is decided by the
amount of load because a motor can run at a constant speed when the output torque and
torque load are equal. The motor speed increases when the output torque becomes greater
than the torque load. You can set a speed limit to maintain the motor speed within a certain
range. Note that torque control is not available during the speed control operations.
