IEC61131-3 Cycle
time exceeded Reaction 2: Downramp /
apply brake / de-energize..
Reduce motor load (less current, more standstill phases of the drive,
lower clock time, lower accelerations), check thermal time constant
and nominal or reference current of the motor. Check motor
dimensioning and replace motor by an adequately dimensioned
model if necessary; use cooling option (water, air) if available,
optimize mechanic components.
Check for controller instability (current and/or speed control loop)
(high frequency oscillation in the current status value) and stabilize
controller by suitable parameter modification.
6282 25218
IEC61131-3 program
stack overflow Reaction 2: Downramp /
apply brake / de-energize..
Check cable (repair line breakage/short circuit).
6283 25219
IEC61131-3 FB
overflow Reaction 2: Downramp /
apply brake / de-energize..
C3S/C3M/C3H:
Adapt thresholds corresponding to the requirements within the
configuration/on the limit objects (IEC program, external PLC) /
within the motor data. Check feedback if necessary:
* EMC immunity/shielding is sufficient (especially, if the error occurs
during automatic commutation)?
* Feedback resolution/line count is correctly configured?
Maybe you are facing 'motor runaway' situaltion caused by positiv
controller feedback in speed control loop -> check motor
commutation from within MotorManager. If it is not correct there
might be the following causes:
* wrong motor wiring (Phases swapped / shifted)
* wrong feedback wiring (e.g. tracks/signals swapped)
* wrong motor configured/connected or motor feedback was not
'phased'.
C3Fluid:
Adapt thresholds corresponding to the requirements within the
configuration/on the limit objects (IEC program, external PLC) /
within the cylinder data. Check feedback if necessary:
* EMC immunity/shielding is sufficient?
* Feedback resolution/line count is correctly configured?

IEC61131-3 illegal
instruction Reaction 2: Downramp /
apply brake / de-energize..
Optimize controller alignment (increase stiffness), increase
following error window and / or following error time, heed notes on
error 7121 “motor stalled”.
In the Homing with “reversal via current” as well as “referencing to
block” modes, it may be necessary to filter the controller control
signal via =2100.20 and/or O2100.10 so that the end stop can be
correctly detected (observe the influence on the control, the current
setpoint must be in block form in the event of a limitation)

IEC61131-3 500us
instruction limit Reaction 2: Downramp /
apply brake / de-energize..
Optimize controller adjustment (increase stiffness),increase
following error window and / or following error time. Refers to the
position controller of the auxiliary axis
