Safety input RFE (rotating field - enable) / stop category 0

When the input of the release or the rotating field release is switched off
the drive is torque-free. Without mechanical brake or lock
the drive may fall through or move
The motor cables are not voltage-free. Only the rotating field is blocked.
When working on the motor or BAMOCAR, the battery motor controller must
be separated from the battery high voltage.
Operation with RFE input
Two-channel enabling lock via a
Safety switchgear.
Enable input FRG/RUN.
Rotary field enable input RFE.
Switch on
Safety device contacts closed.
Release FRG/RUN 0.5 s after RFE.
Safety shutdown
Safety device contacts opened.
No FRG/RUN signal blocks in the first
blocking channel the PWM pulses in the processor.
No RFE signal blocks the PWM pulses
in a second barrier channel after the
Processor.
Switch on again
Unlock the safety device.
Safety device Contacts closed.
Only after renewed release FRG/RUN
in time after the rotating field release RFE
the motor can move.
Operation without RFE input
The RFE input must be connected to the logic voltage.
If the logic voltage is equal to the supply voltage,
the RFE input is bridged with +24 V.
The release FRG/RUN at least 0.5 s
after the RFE signal.
