Sinumerik Alarm 21610 Channel %1 axis %2 encoder %3 frequency limit exceeded

Sinumerik Alarm 21610 Channel %1 axis %2 encoder %3 frequency limit exceeded

Parameters:
%1 = Channel number
%2 = Axis name, spindle number
%3 = String (encoder number)

Definitions:
The maximum permissible frequency of the currently active encoder (axis-specific inter- face signal DB 31 – 48, DBX 1.5 and DBX 1.6) in the axis-specific machine data 36 300 ENC_FREQ_LIMIT [n] (n … encoder number, 1 or 2) has been exceeded. The reference of the actual value to the mechanical carriage position may be lost. The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY (channel not ready).

Reactions:
– Alarm display.
– Interface signals are set.
– Mode group not ready.
– Channel not ready.
– If the axis is a single axis when this alarm is triggered, the alarm is only effective for this axis (not effective for e.g. the channel or mode group)
– Channel not ready.
– NC Stop on alarm.
– NC Start disable in this channel.

Remedy:
Modify MD 36300: ENC_FREQ_LIMIT [n] and interface signal position measuring system 1/2 (DB 31 – 48, DBX 1.5 and DBX 1.6).

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