Program Continuation:

Axis %1 actual velocity alarm limit

%1 = Axis name, spindle number

If the axis has at least one active encoder, then the actual speed of the axis is cyclically checked in the IPO cycle. If there are no errors, the actual velocity can never become greater than specified in the axis-specific MD 36200 AX_VELO_LIMIT (threshold for velocity monitoring). This threshold value in [mm/min, rev/min] is input by an amount that is about 5 to 10% greater than that which can occur at maximum traversing velocity. Drive errors can result in the velocity being exceeded and the alarm is then triggered.

The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY (channel not ready).

-    Mode group 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. Check the speed setpoint cable (bus cable). Check the actual values and direction of position control. Change position control direction if the axis rotates uncontrollably -> axis-specific MD 32110 ENC_FEEDBACK_POL [n] = < -1, 0, 1 >. Increase the monitoring limit value in MD 36200 AX_VELO_LIMIT.

Clear alarm with the RESET key in all channels of this mode group. Restart part program.
