Safety input RFE (Rotating field enable) / Stop class 0

When the input for the release or rotating field release is switched off
the drive is torque-free. Without mechanical brake or lock
the drive may fail 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
be separated from the battery HV voltage.
Operation with an RFE input
Two-channel disable of the enable via a
safety switching device
Enable input FRG/RUN.
Rotary field enable input RFE.
Switching-on
Safety device contacts closed.
Release FRG/RUN 0.5 s after RFE.
Safety switch-off
Safety device contacts open.
No FRG/RUN signal blocks in the first
Block channel the PWM pulses in the processor.
No RFE signal blocks the PWM pulses
in a second blocking channel after the
processor.
Restart
Unlock safety device.
Safety device contacts closed.
Only after renewed release FRG/RUN
after the rotating field release RFE
when the motor moves.
Operation without RFE input
The input RFE must be bridged with the logic voltage
If the logic voltage corresponds to the supply voltage,
the RFE input is bridged with +24 V.
Enable FRG/RUN at least 0.5 s after the RFE signal.
Note: 12 V variant only on request
