51-3
FSM: unequal module
version
Cause:
Type or revision of the module is not supported.
Measure:
- Install safety or fieldbus activation module
appropriate for the firmware and hardware.
- Load firmware appropriate for the module into
the servo drive, see type designation on the
module.
Cause:
The module type is correct but the module
version is not supported by the servo drive.
Measure:
- Check module version; if possible use module
of same version after replacement. Install
suitable safety or fieldbus activation module for
the firmware and hardware.
- If only a module with a more recent version is
available: Load firmware appropriate for the
module into the servo drive, see type designation
on the module.
51-4
FSM: error in SSIO
communication
Cause:
Error in the internal communication connection
between the servo drive and the safety module.
Measure:
- Identify any source of interfering radiation in the
environment of the servo drive.
- Replace the module or the servo drive.
- Please contact the Technical Support team.
51-5
FSM: error in brake
activation
Cause:
Internal hardware error (brake activation control
signals) of the safety module or fieldbus
activation module.
Measure:
Module presumably defective. If possible,
replace with another module.
Cause:
Error in brake driver circuit section in the servo
drive.
Measure:
Servo drive presumably defective. If possible,
replace with another servo drive.
