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)
Positioning operation Check before positioning: Is the
position setting within the
software limits?
Check during positioning
Within range Outside range
Direct operation Absolute posi-
tioning or rela-
tive positioning OK Operation not
possible. No check is performed unless the position
setting is changed during operation.
If the position setting is changed during
operation and the new position is outside the
software limit range, operation decelerates
to a stop to a position within the software
limit range.
Interrupt feeding OK OK If the total number of pulses (the position)
output during speed control is outside the
software limit range, operation decelerates
to a stop to a position outside the software
limit range.
If the sum of the specified amount of move-
ment after the interrupt input and the num-
ber of pulses output until the interrupt input
is received is outside the software limit
range, operation decelerates to a stop to a
position outside the software limit range.
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.
