NOTE
• When the output stop function is valid (Pr.522  "9999"), the DC injunction brake becomes invalid and the motor coasts to
stop when the output frequency drops to the Pr.522 setting or lower.
• 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+2 Hz again while coasting, the motor starts running at Pr.13 Starting frequency (0.01 Hz under PM 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 a PM motor.)
• The output stop frequency function is disabled during PID control, JOG operation, power failure stop, traverse function
operation, or offline auto tuning.
• 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.
CAUTION
• A PM 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.
