7. SPECIAL ADJUSTMENT FUNCTIONS
7 - 25
(1) Instantaneous power failure time of the control circuit power supply > [Pr. PF25 Instantaneous power
failure tough drive - Detection time]
The alarm occurs when the instantaneous power failure time of the control circuit power supply exceeds
[Pr. PF25 Instantaneous power failure tough drive - Detection time].
MTTR (During tough drive) turns on after detecting the instantaneous power failure.
MBR (Electromagnetic brake interlock) turns off when the alarm occurs.
