Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name, spindle number
Definitions: A spindle speed (S value) was programmed with the value zero or with a negative value.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: The programmed spindle speed (S value) must be positive. Depending on the application case, the
value zero can be accepted (e.g. G25 S0).
Program Con-
tinuation:
Clear alarm with NC START or RESET key and continue the program.
16770 [Channel %1: ] Block %2 axis %3 no measuring system available
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name, spindle number
Definitions: One of the following spindle functions has been programmed, the position control requires:
SPCON,
SPOS, SPOSA,
COUPON,
G331/G332.
The position control requires at least one measuring system.
No measuring system has been configured in MD30200 $MA_NUM_ENCS of the programmed spin-
dle.

Remedy: Please inform the authorized personnel/service department. Retrofit a measuring system.
Program Con-
tinuation:
Clear alarm with the RESET key. Restart part program
16771 [Channel %1: ] Block %3 following axis %2 overlaid movement not
enabled
Parameters: %1 = Channel number
%2 = Axis name, spindle number
%3 = Block number, label
Definitions: No gear synchronization and no overlay movement can be executed because this is not enabled at
the VDI interface.
Reaction: Alarm display.
Remedy: Set the NC/PLC interface signal <Freigabe_Folgeachsueberlagerung/> (enable following axis over-
lay).
Program Con-
tinuation:
Alarm display showing cause of alarm disappears. No further operator action necessary.
16772 [Channel %1: ] Block %2 axis %3 is the slave axis, the coupling is being
opened
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis, spindle
Definitions: The axis is active as a slave axis in a coupling. In the REF operation mode, the coupling is opened.
The alarm can be suppressed by means of MD11410 $MN_SUPPRESS_ALARM_MASK Bit29 = 1.
Reaction: Alarm display.
Remedy: The coupling will be closed again after having exited the REF operation mode.
Program Con-
