1000* Terminal assigned more than once POWER ON
as from SW 2: Reset key
S When inputting machine data for axis assignment
No machining of the axes for which the connection number concerned has been assigned more than once
S Servo disable for the axis concerned
S Mode Group Ready removed
S Interlocking of NC START
S Interlocking of NC RDY relay
S A connection number of a measuring circuit module has been specified more than once under MD200x or
MD384x.
Example: MD3840 = 01060000, MD3845 = 01060000. Connection number 6 of the 1st measuring circuit
module has thus been assigned more than once.
S Check and correct MD200x or MD384x
Applies up to SW 2
1000* Terminal assigned more than once Reset key
S Cyclic for digital drives if double assignment of setpoint output via MD is permissible.
S As before
S Two NC axes assigned the same digital setpoint output are being controlled at the same time. This simulta-
neous output of setpoints at the same drive is not allowed.
The interface signal ”Parking axis” is not allowed for the axis that is not being controlled.
S One of the NC axes must be disconnected from the control loop (servo enable, follow-up mode).
Applies as from SW 3
1004* Permissible feed/limit frequency exceeded Reset key
Cyclic
S Interlocking of NC START
S Interlocking of Mode Group Ready
S Setpoint 0
S Servo enable is cancelled after the time in NC MD “Cutout delay”
S Follow-up mode
The maximum value set in the NC MD “Encoder frequency” has been exceeded.
Is only activated for C axes to spindles (assignment via NC MD 461*).
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.
Check feedrate and NC MD “Encoder limit frequency” MD 308*.
1008* Speed controller limitation Reset key
POWER ON and warm restart
S Interlocking of NC START
S Interlocking of Mode Group Ready
Alarm causes machining stop
S Speed alarm limit has been reached
S Check current controller
S Set speed control loop to a slower rate
S Increase parameters
S Check mechanical parts
