Diagnostic messages and fault clearance
01h
Software error
Definable as:
F
/-/-
Diagnostic memory: always
An internal firmware error has been detected.
Contact Festo Service.
– Resettable: Cannot be reset; software reset is necessary.
Definable error reaction(s): A
02h
Default parameter file invalid
Definable as:
F
/-/-
Diagnostic memory: always
An error has been detected when examining the default parameter file. The file is damaged.
Reload the default parameter file into the device via a firmware update. If the error is still present,
it means the memory may be faulty and the device needs to be replaced.
– Resettable: Cannot be reset; software reset is necessary.
Definable error reaction(s): A

Zero angle determination

Diagnostic memory: always
The rotor position could not be clearly identified. The commutation point is invalid.
Is there a motor with encoder and, if yes, is the encoder cable connected? The drive is blocked:
Ensure freedom of movement.
Excessively high load: Reduce load.
The axis is not fastened stiffly enough: Stiffen the axis mounting.
The effective load is not fastened stiffly enough on the axis: Stiffen the connection.
Effective load can vibrate: Form a stiffer load; modify the natural frequency of the load.
If several drives are fitted in a system that can vibrate: Carry out commutation point search one
after the other.
Controller parameters have been set incorrectly: Determine the controller parameters and set the
correct value. To do this, you may have to perform a commutation point search without a load
(remove the load, correctly set the tool mass and applied load), start the axis, connect the load
(correctly set the tool mass and applied load), determine the new controller parameters (see FCT
help on controller parameterisation), reparameterise the drive and then restart the commutation
point search with new controller parameters.
This error can also occur if the set motor current is too low to move the shaft and any possible
load. Correct the settings for the motor current, if necessary.
– Resettable: Error can be reset immediately.
