■When instantaneous power failure time of control circuit power supply > [Pr. PF25 SEMI-F47
function - Instantaneous power failure detection time]
The alarm occurs when the instantaneous power failure time of the control circuit power supply exceeds [Pr. PF25 SEMI-F47
function - Instantaneous power failure detection time]. MTTR (During tough drive) turns on after the instantaneous power
failure is detected.
MBR (Electromagnetic brake interlock) turns off when the alarm occurs.
