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

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 overv24 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.
