206
Count method movement
amount fault
■ 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.
■
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. (

207 OPR request ON
■ 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.
■ Action
Execute the machine OPR (positioning No. 9001).

209 OPR restart not possible
■ 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.
■
Action
Start the machine OPR (positioning start No.
9001) again. (
