Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The monitoring cycle MD 1002: $MD_MONITOR_CYCLE_TIME must be identical for
both axes on 2-axis modules.
Reactions: - NC not ready.
- The NC switches to follow-up mode.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: Please inform the authorized personnel/service department. Modify MD 1002:
$MD_MONITOR_CYCLE_TIME for both axes.
Program Con- Switch control OFF - ON.
tinuation:
300712
Axis %1 drive %2 configuration of controller structure (higher dynamic response)
not possible
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: On a 2-axis module, an attempt was made to change the control structure via MD 1004:
$MD_CTRL_CONFIG in such a way that speed control would be performed in advance of
current control. This is only allowed on 1-axis modules in order to improve the dynamic
response!
Reactions: - NC not ready.
- The NC switches to follow-up mode.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: Please inform the authorized personnel/service department. In the drive MD 1004:
$MD_CTRL_CONFIG bit 2 must be set to zero (no) (default setting). This ensures that the
current control acts before the speed control.
Program Con- Switch control OFF - ON.
tinuation:
300713
Axis %1 drive %2 lead time for position controller invalid
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The derivative-action time describes the point in time the setpoints are taken over in the
drive. The derivative-action defined by the NC must be smaller than the position controller
cycle. The derivative-action time must be an integer multiple of the speed controller cycle.
Reactions: - NC not ready.
- The NC switches to follow-up mode.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
