Axis %1, drive %2 system error, error codes %3, %4
%1 = NC axis number
%2 = drive number
%3 = error code 1
%4 = error code 2
The drive has signaled a system error. For an exact breakdown of error codes,
see /FBA/ DB1, Operational Messages/Alarm Responses.
NC not ready.
Under certain circumstances it can be switched over across the entire channel
via MD.
Channel not ready.
NC stopped in response to alarm.
NC start disable.
The NC switches to follow-up mode.
Alarm display.
Interface signals are set.
Please inform the authorized personnel/service department.
Reinitialize the drive.
The search for the precise cause of error can only be performed by the develop-
ment team. The displayed error codes are always needed for this.

Switch control system OFF and ON again.
Axis %1, drive %2 measuring circuit fault in motor measuring system
%1 = NC axis number
%2 = drive number
Signal level of motor encoder too small or noisy. SSI encoder: Parameter setting
error (bit 9 of MD 5027 Bit 9 not set)
Mode group not ready.
Under certain circumstances it can be switched over across the entire channel
via MD.
Channel not ready.
NC start disable.
NC stopped in response to alarm.
The NC switches to follow-up mode.
Alarm display.
Interface signals are set.
Please inform the authorized personnel/service department.
Check encoder, encoder leads and connectors between drive motor and 611D
module: check for temporary interruptions (loose contact) - e.g. caused by
movements in cable tow.
S
Replace motor, encoder and/or cable if necessary
S
Check shield bond to front plate of closed-loop plug-in module (top screw)
S
Replace the control module.
S
Check distance between gear wheel and sensor on gear wheel encoders
(The HLA module does not feature a gear wheel encoder. This is a measur-
ing system connected to the hydraulic equipment.).
Switch control system OFF and ON again.
