The machine OPR is started.
The OPR is executed based on the positioning pattern set in AlphaStep/5-
phase.)

(3) Servo OFF
• For 5-phase (open loop control system), if the motor is moved by an
external force when servo OFF occurs, it is not possible to detect the
position and position information is not updated.
• Do not rotate the motor during servo OFF. If the motors are rotated, a
position displacement occurs.
• For 5-phase (open loop control system), "OPR request flag" (
Md.31
Status
: b3) turns ON in a servo OFF state. After turning servo ON,
perform an OPR again.
• For 5-phase (open loop control system) when an encoder is installed,
checking position displacement and maladjustments is possible by
monitoring "position feedback" and "external encoder counter value" in
the optional data monitor. Refer to the manual of AlphaStep/5-phase for
the units and increase direction of the encoder count value, and checking
methods.
