FSM: error in cross compari
-
son for processors 1 - 2
Cause:
Timeout during cross-comparison (no data) or cross-comparison faulty (data for
μC1 and μC2 are different).
▪ Error in cross-comparison for digital I/O.
▪ Error in cross-comparison for analogue input.
▪ Error in cross-comparison for internal operating voltage measurement (5 V,
3.3 V, 24 V) and reference voltage (2.5 V).
▪ Error in cross-comparison for SIN/COS angle encoder analogue values.
▪ Error in cross-comparison for programme sequence monitoring.
▪ Error in cross-comparison for interrupt counter.
▪ Error in cross-comparison for input map.
▪ Error in cross-comparison for violation of safety conditions.
▪ Error in cross-comparison for temperature measurement.
Measure:
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 shield design; are there any external
interference sources?
▪ Safety module may be defective – is error eliminated after replacing the
module?
▪ Check whether a new firmware for the servo drive or a new version of the
safety module is available.
Group 59: FSM: Internal Error
59-1
FSM: failsafe supply /safe
pulse inhibitor
Cause:
Internal error in module in failsafe supply circuit or in the driver supply for the
upper and lower switches.
Measure:
Module defective, replace.
59-2
FSM: error external
power supply
Cause:
• Reference voltage 2.5 V outside tolerance.
• Logic supply overv24 V detected. Measure:
Module defective, replace.
59-3
FSM: error internal
power supply
Cause:
Voltage (internal 3.3 V, 5 V, ADU reference) outside the permissible range.
Measure:
Module defective, replace.
