C-21
FM 351 Positioning Module
C79000-G7076-C351-02
No. Diagnostic
Interrupt
Meaning
127
Incorrect stationary speed Yes
Cause
The value for the stationary speed is outside the
permitted range of 0 to 100 000µm/min.
128
Incorrect control mode Yes
Cause
You have specified a control mode outside the
permitted range of 1 to 4.
129
Incorrect start speed for reference point approach Yes
Cause
You have specified neither 0 nor 1 as the start
speed.
130
Incorrect switchover difference in direction + Yes
Cause
Linear axis: Range between 0 and 100 m or 1000 m,
(depending on the resolution).
Rotary axis Range greater than the end of the rotary
axis and less than 1/2 the target range
131
Incorrect switchover difference in direction – Yes
Cause
Linear axis: Range between 0 and 100 m or 1000 m,
(depending on the resolution).
Rotary axis Range greater than the end of the rotary
axis and less than 1/2 the target range
132
Incorrect switch-off difference in direction + Yes
Cause
The switch-off difference is greater than the
switchover difference plus, less than 1/2 the target
range, or is outside the permitted range between 0
and 100 m or 1000 m (depending on the resolution).
133
Incorrect switch-off difference in direction – Yes
Cause
The switch-off difference is greater than the
switchover difference minus, less than 1/2 the target
range, or is outside the permitted range between 0
and 100 m or 1000 m (depending on the resolution).
200
Incorrect resolution Yes
Cause
You have specified a resolution < 0.1 µm/pulse or
> 1000 µm/pulse.
You have specified a distance/encoder revolution
and a number of pulses/encoder revolution, that
results in a resolution of < 0.1 or > 1000.
201
Encoder does not match the working range / rotary axis
range
Yes
Cause
SSI encoder and rotary axis: The encoder does not
exactly cover the rotary axis range.
Linear axis: The encoder does not cover at least the
working range (incl. software limit switch).
