Program Continuation:

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)

-    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.

The value of machine data MD 1210: $MD_CURRENT_FILTER_1_SUPPR_FREQ (blocking frequency of current setpoint filter 1) or MD 1213:

$MD_CURRENT_FILTER_2_SUPPR_FREQ (blocking frequency of current setpoint filter 2) or MD 1216: $MD_CURRENT_FILTER_3_SUPPR_FREQ (blocking frequency of current setpoint filter 3) or MD 1219: $MD_CURRENT_FILTER_4_SUPPR_FREQ (blocking frequency of current setpoint filter 4) must be less than the reciprocal value of two current controller cycles MD 1000: $MD_CURRCTRL_CYCLE_TIME (current controller cycle). (1/2*MD 1000*31.25 microsec)

Clear alarm with the RESET key in all channels. Restart part program.
