•
With thermal overload, the error is set and the output(s) shut off. After
the driver has cooled off, the outputs are switched back on and so on.
The error, however, remains until it is cleared. Thermal overload can
occur if several outputs are overloaded in excess of 80 mA.
Note: Light bulbs, for example, cannot be controlled as their inrush
current causes a short-circuit.
Cause:
1. Short circuited outputs
2. One or more outputs are overloaded.
Remedy:
For 1. Eliminate short circuit or limit switching current (< 350 mA)
For 2. Drop current, depending on output, to < 80 mA.

Parameters".
F267 Erroneous internal hardware synchronization
Cause:
The drive control is synchronized on the bus interface (SERCOS,
Profibus, Interbus, ...). The correct function of the synchronization is
monitored. If the average value of the deviation exceeds 5 µs, this error
is generated.
Remedy:
Replace drive controller.
F269 Error during release of the motor holding brake
After drive enable is set or while running the brake monitor command the
motor does not move despite that. The motor torque command is equal
to the brake holding torque.
Cause:
1. Motor brake not connected
2. Axis mechanically jammed
3. Frictional torque > brake nominal torque.
Remedy:
on 1. connect brake
on 2. check mechanics and eliminate jam
on 3. switch brake monitor off
