Rated Output Current
(CL-V/f)
Represents the range of variable control.
(Keep increases in motor temperature in
mind when connecting and running
motors in this manner.)
This is the motor torque that can be
generated at low speed during startup and
the corresponding output frequency
(rotation speed). Drive capacity must be
considered if significant torque is required
at low speed.
Automatically tunes electrical motor
parameters.
Controls maximum motor torque to
protect machines and loads.
Sets load torque slip for motors. Used to
distribute motor loads.
Locks servos without an external position
controller to prevent movement caused by
external force.
