Sinumerik Alarm 300756 Axis %1 drive %2 speed hysteresis of setpoint current smoothing invalid


Sinumerik Alarm 300756 Axis %1 drive %2 speed hysteresis of setpoint current smoothing invalid

Parameters:
%1 = NC axis number
%2 = Drive number

Definitions:
The value in MD 1246: $MD_CURRENT_SMOOTH_HYSTERESIS $MD_CURRENT_SMOOTH_HYSTERESIS (hysteresis of the speed-dependent M set- point smoothing) is greater than or equal to the value in MD 1245: $MD_CURRENT_SMOOTH_HYSTERESIS (threshold of the speed-dependent M set- point smoothing).

Reactions:
– NC not ready.
– Channel not ready.
– Channel not ready.
– NC Stop on alarm.
– NC Start disable in this channel.
– The NC switches to follow-up mode.
– Alarm display.
– Interface signals are set.

Remedy:
Please inform the authorized personnel/service department. Check and, if necessary, correct the torque adaptation factor MD 1246: $MD_CURRENT_SMOOTH_HYSTERESIS (hysteresis of the speed-dependent M setpoint smoothing) or MD 1245: $MD_CURRENT_SMOOTH_HYSTERESIS (threshold of the speed-dependent M set- point smoothing). $MD_CURRENT_SMOOTH_SPEED.

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