58-4 FSM: buffer internal
communication
Cause:
- Communication connection disturbed.
- Timeout / data error / incorrect sequence
(packet counter) in data transmission between
the servo drive and the safety module.
- Too much data traffic, new requests are being
sent to safety module before old ones have been
responded to.
Measure:
- Check communication interfaces, cabling,
shield connection etc.
- Check whether other devices have read access
to the servo drive and the safety module during a
parameterisation session. This may overload the
communication connection.
- Check whether the firmware versions of safety
module and servo drive and the versions of
parameterisation program and SafetyTool are
compatible.
58-5 FSM: communication
safety module - servo
drive
Cause:
- Packet counter error during transmission
between μC1 and μC2.
- Checksum error during transmission between
μC1 and μC2.
Measure:
- Internal malfunction in the servo drive.
- Check whether the firmware versions of safety
module and servo drive and the versions of
parameterisation program and SafetyTool are
compatible.
