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!
Reaction: 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 Switch control OFF - ON.
Continuation:
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.
Reaction: 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 10082:
$MN_CTROUT_LEAD_TIME (derivative-action time).
Program Switch control OFF - ON.
Continuation:
300714 Axis %1 drive %2 power section code invalid
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The code number of the power section entered in drive MD 1106: $MD_INVERTER_CODE (power
section code number) does not match the power section in the drive configuration display (MD 13020:
$MD_DRIVE_INVERTER_CODE).
Reaction: 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. Delete modified machine data (e.g.
controller data). Reset the drive (delete the bootfile) and repeat the startup.
Program Switch control OFF - ON.
