Stop Function Section 9-10
Note 1. Origin return is not possible if 0 is outside the software limit range. For ex-
ample, if the software limits are 100 and 200 respectively, origin return is
not possible.
2. When the software limit function operates, an error related to the software
limit function, such as manual CW limit error (error code 5070), will be gen-
erated.
9-10 Stop Function
9-10-1 Outline
Pulse output is stopped by the PCU for a variety of problems or situations that
can arise during positioning. The situations that will result in the PCU stopping
pulse output are related to one of the following 3 areas.
• The PLC as a whole (or some other part of the PLC)
• Internal PCU operation
• Input signals
Operation can be stopped either according to the deceleration curve or imme-
diately.
Memory opera-
tion 1-axis or linear
interpolation
positioning OK Operation not
possible. No check is performed unless the position
setting is changed with the start of the forced
interrupt.
If the position setting is changed with the
start of forced interrupt, and the new position
is outside the software limit range, operation
decelerates to a stop to a position within the
software limit range.
Speed control OK OK If the total number of pulses (the position)
output is outside the software limit range,
operation decelerates to a stop to a position
outside the software limit range.
Interrupt feeding OK OK Same operation as interrupt feeding in direct
operation.
Direct operation
or memory oper-
ation Origin return OK Operation not
possible. Not checked
Jogging OK OK If the total number of pulses (the position)
output is outside the software limit range,
operation decelerates to a stop to a position
outside the software limit range.
Positioning operation Check before positioning: Is the
position setting within the
software limits?
Check during positioning
Within range Outside range
