5.2 Safety input RFE (Rotating field enable)
Stop class 0
Warning:
If the inputs of the enable or of the rotating field enable are
switched off, the drive is free of torque. The drive could move
if there is no mechanical brake or block provided.
The motor conductors are not dead. Only the rotating field is
disabled. Prior to any work or maintenance on the motor or
the BAMOCAR, the battery motor controller must be
completely disconnected from the mains power supply of the
battery.
Operation with an RFE input
5-3 E-BAC-REF1-2
Two-channel disable of the enable via a
safety switching device.
Enable input FRG/RUN +
Rotating field enable input RFE.
Switching-on
Contacts of the safety device closed,
enable FRG/RUN 0.5s after RFE.
Safety switch-off
Contacts of the safety device open:
- there is no FRG/RUN signal in the 1
st
disable channel to disable the PWM pulses
in the processor
- there is no RFE signal in the 2
nd
disable
channel to disable the PWM pulses at
the output of the processor
Restart
Release the safety switching device.
Contacts of the safety device closed.
The motor can only move after a second
disable FRG/RUN (after the rotating field
enable).
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 +12/+24V.
Enable FRG/RUN at least 0.5s after the RFE
signal.
