Action:
This is an internal error in the module that should
not occur during operation.
Check the operating conditions (temperature, air
humidity, condensation).
Check the EMC wiring as
specified and screening
design; are there any external interference
sources?
Safety module may be faulty – is error eliminated
after replacing the module?
Check whether new firmware for the servo drive
or a new version of the safety module is available
from the manufacturer.
59 1 FSM: Fail-safe mode supply/safe pulse
inhibitor
Cause: Internal error in module in failsafe supply circuit
section or in the driver supply for the upper and
lower switches.
Action: Module faulty, replace.
2 FSM: Logic failure / intermediate circuit Cause: Reference voltage 2.5 V outside tolerance.
Logic supply overvoltage +24 V detected.
Action: Module faulty, replace.
3 FSM: Error internal power supply Cause: Voltage (internal 3.3 V, 5 V, ADU reference)
outside the permissible range.
Action: Module faulty, replace.
4 FSM: Error management, too many Cause: Too many errors have occurred simultaneously.
