Motor brake and stop operation
REMARKS
⋅ Motor coasts when the command value drops to Pr.522 or lower while the start signal is ON. If the command value exceeds
Pr.522+2Hz again while coasting, the motor starts running at Pr.13 Starting frequency (0.01Hz under IPM motor control). When the
motor re-accelerates after coasting, the inverter may trip in some parameter settings. (Activation of the restart function is
recommended especially for an IPM motor.)
⋅ Output stop function is disabled during PID control, JOG operation, and power failure stop.
⋅ Output stop function does not operate during reverse rotation deceleration. However, when the frequency setting signal and
output frequency falls to Pr.522 or lower, the inverter coasts to a stop.
⋅ During the output stop due to the output stop function (when forward/reverse command is given, but frequency command is not
given), FWD/REV LED indication on the operation panel flickers fast.
An IPM motor is a motor with interior permanent magnets. High voltage is generated at motor terminals while
the motor is running. Do not touch motor terminals and other parts until the motor stops to prevent an electric
shock.
