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 signals a system error. For an exact breakdown of error codes, see
/FBA/ DB1, Operational Messages/Alarm Reactions.

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 closed-loop 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.
