C-16
FM 351 Positioning Module
C79000-G7076-C351-02
No. Diagnostic
Interrupt
Meaning
14
Change greater than the half rotary axis range
Yes
Cause The speed/frequency is too high or there are
incorrect sudden changes in the actual value.
15
Change greater than rotary axis range
Yes
Cause The speed/frequency is too high or there are
incorrect sudden changes in the actual value.
16
Incremental dimension for incremental dimension number
252 not transferred (FM 451)
Yes
Cause The incremental dimension was not transferred.
17
Approach to incremental dimension for incremental
dimension number 252 not possible (FM 451)
Yes
Cause The distance between the current actual position
and the specified incremental dimension is less than
the switchover difference or switch-off distance.
18
Wrong incremental dimension for incremental dimension
number 252 (FM 451)
Yes
Cause The incremental dimension is outside the working
range.
Class 2: Operator Errors
Operator errors are detected when the control signals are modified in the user data
area. Operator errors lead to the positioning being terminated.
No. Meaning Diagnostic
Interrupt
1
Illegal operating mode
no
Cause
The selected operating mode is illegal.
3
Illegal interface job
no
Cause The selected signal is illegal with this operating
mode
4
Incorrect mode parameter
no
Cause • In the “Jogging” mode, the speed specified is not
equal to the rapid speed or the creep speed
• In the “incremental approach” mode, the
incremental dimension is not equal to 1 to 100 or
not equal to 254 and 255
5
No start enable
no
Cause No start enable when starting.
7
Target/target range outside working range
no
Cause Specified or calculated target outside the software
limit switches.
8
Parameters not set for the axis
no
Cause Incorrect or no machine data were set for the axis
