Operation status at error occurrence
■Description
In the count method 1 and 2 machine OPR, a
parameter "Setting of movement amount after near-
point dog ON" is smaller than a distance necessary
for deceleration stop from an OPR speed.
■Operation status at error occurrence
The machine OPR does not start.
■Description
The OPR request flag is turned ON when a fast-
OPR is started (positioning start No. 9002).
■Operation status at error occurrence
The fast OPR is not started.
■Description
The restart command is turned ON after the
machine OPR is stopped using a stop signal.
■Operation status at error occurrence
The restart is not carried out.
■Description
Communication cannot be carried out with the
servo-amplifier using an absolute position
restoration instruction.
■Operation status at error occurrence
The absolute position restoration is not carried out.
CHAPTER 15 TROUBLESHOOTING
Action/Related buffer memory address/Set
range (Setting with program)
■Action
• Calculate the movement distance using a
speed limit, OPR speed, and deceleration time,
and set the movement amount after near-point
dog ON so that the distance becomes a
deceleration distance or longer.
• Adjust the near-point dog position so that the
movement amount after near-point dog ON
becomes longer. ( Page 332, Section
8.2.7, Page 335, Section 8.2.8)
