The load is excessive, resulting in motor lock.

Reduce the load and check that the brake is released

(if a mechanical brake is used).

Note: Monitor the operation command or frequency setting values, etc., on the LED or LCD monitor after selecting

the respective functions.

Raise the torque boost.

The motor does not rotate if the following commands are issued.

An operation command is issued while the coast-to-stop or DC braking command is output

A reverse operation command is issued with the “H08 Rev. phase sequence lock” value set to 1.
