57-6
FSM: overtemperature
Cause:
▪ The safety module‘s temperature monitor has been triggered; the temperatu
-
re of μC1 or μC2 was below -20° or above +75°C.
Measure:
▪ Check the operating conditions (ambient temperature, control cabinet tempe
-
rature, installation situation in the control cabinet).
▪ If the servo drive is experiencing high thermal load (high control cabinet
temperature, high power consumption / output to motor, large number of
occupied slots), a servo drive of the next higher output level should be used.
Group 58: FSM: Communication / Parameterisation
58-0
FSM: plausibility check of
parameters
Cause:
The plausibility check in the safety module has revealed errors, e.g. an impermis
-
sible angle encoder configuration; the error is triggered when a validation code
is requested by the SafetyTool and when parameters are backed up in the safety
module.
Measure:
Note instructions for SafetyTool for complete validation; check parameterisation.
58-1
FSM: general error
parameterisation
Cause:
Parameterisation session active for > 8 hrs. The safety module has thus termin
-
ated the parameterisation session. The error message is saved in the permanent
event memory.
Measure:
Terminate parameterisation session within 8 hrs. If necessary, start a new para
-
meterisation session and continue.
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.
