(2) OPR
The method and some operation of the OPR using the IAI electric actuator
controller differ from those of the OPR using the servo amplifier.
(a) OPR method that can be used
[Pr.43] OPR method
Near-point dog method
Count method 1)
Count method 2)
Data set method
Scale origin signal detection method
Driver OPR method
1: The error "OPR method invalid" (error code: 232) occurs and OPR is not
performed.
(b) Driver OPR method
The following shows an operation outline of the OPR method "Driver
OPR method".
The OPR is executed based on the positioning pattern set in the IAI
electric actuator controller. Set the setting values of OPR in the
parameters of the IAI electric actuator controller. The operation of OPR
and "b0: Lower limit", "b1: Upper limit" and "b6: Near-point dog signal"
of "[Pr.22] Input signal logic selection" depend on the specification of
the IAI electric actuator controller, so that refer to the IAI electric
actuator controller manual and match the settings. For parameters that
can be set by the Simple Motion module, refer to Section 5.1.3 "Setting
items for OPR parameters".
This method is not available except for the stepping driver (including
the IAI electric actuator controller). If the method is executed, the error
"OPR method invalid" (error code: 232) occurs.
(c) Backlash compensation after the driver OPR method
When "[Pr.11] Backlash compensation amount" is set in the Simple
Motion module, set the positive direction in "[Pr.44] OPR direction".
