Safety input RFE (rotating field enable)
Stopp-Class 0
Warning!
If the input 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
servo-drive, the servo-drive must be completely disconnected
from the mains power supply.
Operation with RFE input
DS-BAxDPC/E-DS-400-REF-1-1/1-2/1-3
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 RFE).
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 +24V.
Enable FRG/RUN at least 0.5s after the RFE
signal.
