■ Starting procedure
At the run command, the inverter makes the motor produce the torque specified with parameter
f343. As soon
as a torque output command is issued, a brake release request signal is put out through the brake output terminal.
Upon expiration of the brake release time set with
f345, the motor starts to accelerate.
■ Stopping procedure
At the stop command, the operation frequency is decreased to the creep frequency set with parameter
f346,
and put out the braking request after the creep time 1 set with
f340. And then, the creep frequency is
maintained for the creep time set with
f347. While the creep frequency is maintained, the brake release signal
is put out through the braking signal output terminal to apply the brake.

Note 1) Do not change the RUN/STOP and the forward/reverse signal during creep operation.
Set the interlock circuit not to change the above switching.
