The upper adaptation speed MD 1412: $MD_SPEEDCTRL_ADAPTSPEED_2 (upper
adaption speed) is less than the lower adaptation speed MD 1411:
$MD_SPEEDCTRL_ADAPTSPEED_1 (lower adaption speed).
- 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.
- Channel not ready.
Please inform the authorized personnel/service department.
$MD_SPEEDCTRL_ADAPTSPEED_2 (upper adaption speed) and MD 1411:
$MD_SPEEDCTRL_ADAPTSPEED_1 (lower adaption speed).
Clear alarm with the RESET key in all channels. Restart part program.
Axis %1 drive %2 speed control gain too high
%1 = NC axis number
%2 = Drive number
The proportional gain of the speed controller MD 1407: $MD_SPEEDCTRL_GAIN_1 (P
gain of speed controller) or MD 1408: $MD_SPEEDCTRL_GAIN_2 (P gain of upper
adaption speed) has been set too high.
- 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.
- Channel not ready.
Please inform the authorized personnel/service department. Set a smaller value for the
proportional gain in MD 1407: $MD_SPEEDCTRL_GAIN_1 (P gain of speed controller) or
MD 1408: $MD_SPEEDCTRL_GAIN_2 (P gain of upper adaption speed). (Allow for the
active speed controller adaptation.)
Clear alarm with the RESET key in all channels. Restart part program.
Axis %1 drive %2 blocking frequency of setpoint current filter too high
%1 = NC axis number
%2 = Drive number
The blocking frequency of a current setpoint filter is greater than the reciprocal value of 2
current controller cycles (violation of the sampling theorem). (1/2*MD 1000*31.25
microsec)
