Program Continuation:

Axis %1 drive %2 limit value for safe velocity too large

%1 = Axis number %2 = Drive number

Booting has been interrupted. The pulses remain disabled.

Request: In monitoring cycle.

The limit value of the safe velocity exceeds the velocity corresponding to a limit frequency of 200 kHz (300 kHz for 840D with SW4.2 and higher and for 840C with SW6.1 and higher).

The max. permissible speed that can be monitored is determined as follows: nmax[rev/min] = (200000[Hz] * 60) / encoder marks value Monitoring condition:

Modify MD 1331: $MD_SAFE_VELO_LIMIT[n] <= (1 / ue) * nmax

-    Mode group not ready.

-    Channel not ready.

-    NC Start disable in this channel.

-    Interface signals are set.

-    Alarm display.

-    NC Stop on alarm.

Please inform the authorized personnel/service department. Check the entry in the machine data MD 1331: $MD_SAFE_VELO_LIMIT[n] (safe velocity limit values) correct, if necessary, and perform POWER ON.

Switch control OFF - ON.
