Note: If b91 = 001, reverse command is disabled.
b91 Reverse run
A00 = 000 and b91 = 001, b88 (motor direction) disable, the inverter is set to forward operation.
A00 = 001 or 002, and b91 = 001, reverse command is disable.
b92 Stopping method
1.) b92 = 000: after receiving stop command, the motor will decelerate (ramp) to stop according
to setting of A05.
2.) b92 = 001: after receiving stop command, the motor will free-run (coast) to stop.
b93 Status monitoring display
b93 = 001 display shows Output frequency, Motor current, Output voltage, DC link voltage, or
PID feedback.
b94 Copy module
Note: Parameter copy facility is applicable only to inverters with the same voltage and KW capacity.
000: Reverse enable
001: Reverse disable
000: Decelerate to stop
001: Free run (Coast) to stop
000: Disable
