8 OPR CONTROL
(4) Turn OFF the near-point dog at a sufficient distance from the OP.
Although there is no harm in operation if the near-point dog is turned OFF
during a machine OPR, it is recommended to leave a sufficient distance from
the OP when the near-point dog is turned OFF for the following reason.
If machine OPRs are performed consecutively after the near-point dog is
turned OFF at the time of machine OPR completion, operation will be
performed at the OPR speed until the hardware stroke limit (upper/lower limit)
is reached.
If a sufficient distance cannot be kept, consider the use of the OPR retry
function.
(5) When a machine OPR is stopped with the stop signal, perform a machine
OPR again.
If the restart command is turned ON after a stop with the stop signal, an error
"OPR restart not possible" (error code: 209) occurs.
