Operation Selection Function 2 (Pr. 65 To Pr. 79); Retry Function (Pr. 65, Pr. 67 To Pr. 69) - Mitsubishi Electric FR-V500 Instruction Manual

(5) Protective functions
If any of the following errors occurs in the brake sequence mode, the inverter results in an alarm, shuts off the
output, and turns off the brake opening request signal (BOF terminal).

Deceleration is not normal during deceleration operation (Use Pr. 284 to select this function.)
E.MB2
(Except stall prevention operation)
Brake opening request signal (BOF) turned on though the motor is at a stop.
E.MB3
(Gravity drop prevention function)
More than 2s after the run command (forward or reverse rotation) is input, the brake opening request signal
E.MB4
(BOF) does not turn on.
Although more than 2s have elapsed after the brake opening request signal (BOF) turned on, the brake

opening completion signal (BRI) does not turn on.
Though the inverter had turned on the brake opening request signal (BOF), the brake opening completion
E.MB6
signal (BRI) turned off midway.
Although more than 2s have elapsed after the brake opening request signal (BOF) turned off at a stop, the

3.11.1 Retry function (Pr. 65, Pr. 67 to Pr. 69
When the inverter output is stopped by the protective function (major fault), this function causes the inverter to
automatically reset itself to make a retry. You can select whether retry operation is to be performed or not,
alarms reset for retry, number of retries made, and waiting time.
