2009* Contamination measuring system spindle POWER ON
S Cyclic
S Interlocking of NC START
S Interlocking of Mode Group Ready
S Where measuring systems have a contamination signal (e.g. EXE) an error is sent to the NC from the measu-
ring system.
S Check the measuring system against the manufacturer’s specifications.
2010* Pulse code monitoring Reset key
S Cyclic
S Interlocking of Mode Group Ready
S Interlocking of NC START
S Alarm causes machining stop
S Transmission error or interference from encoder
S Check encoder, cable, connecter
2011* Zero marks monitoring has responded Reset key
S Cyclic, depending on the tolerance band set for the difference pulses
S Interlocking of NC START
S Machining stops
Pulses have been lost per encoder revolution, above the permitted tolerance band, due to transmission errors,
interference or too high speed. The reference counter checks this zero mark.
S Check the encoder pulses
S Check transmission path
2014* Setpoint or actual speed alarm limit exceeded Reset key
2014* Speed setpoint value alarm limit responded Reset key
Cyclic
S Interlocking of NC START
S Interlocking of Mode Group Ready
S Setpoint 0
S Servo enable is removed after the time in NC MD “Cutout delay servo enable” has elapsed
S Follow-up mode
S The motor could not follow the entered speed setpoint.
S During start-up: incorrect position control direction, incorrect spindle multgain
S The speed actual value exceeds the maximum spindle speed + tolerance
If the service number 309 is indicated here, the reason for the alarm is a format overflow, which can be avoided by
reduction of the resolution. Another reason can also be the resolution of the C axis assigned.
S Check the drive
S Check position control direction
S Match spindle multgain (MD 468*)
S Check speed setpoint cable
S Check actual values (pulse encoder)
S Increase spindle speed tolerance (MD 445*)
S Increase acceleration time constant (MD 419* – 426*)
S Alarm ”Setpoint or actual speed alarm limit exceeded”: up to SW 3
S Alarm ”Speed setpoint alarm limit actuated”: as from SW 4
2015* Drift too high Reset key
With input of NC MD 401* or with semi-automatic drift compensation (axis only)
Interlocking of NC START
The entered drift is greater than approx. 500 mV. In the case of semi-automatic drift compensation, the drift to be
compensated for by the NC has risen to above approx. 500 mV.
Check whether the drift has been compensated for correctly at the driving unit.
