Dogless Z-Phase Reference Home Position Return Type - Mitsubishi Electric MR-JE-*C Instruction Manual

12. WHEN USING WITH A GENERAL-PURPOSE INTERFACE

12.4.14 Dogless Z-phase reference home position return type

A position, which is shifted to by the home position shift distance from a position specified by the Z-phase
pulse immediately after the start of the homing, is set as the home position.

The setting value of [Pr. PT08 Home position return position data] and [Pr. PT58 Home position return
position data (extension parameter)] is used as the position address at the homing completion.
Device/parameter to be used

DI0 (Point table No. selection 1) to DI7 (Point
table No. selection 8)

Switch on MD0.
Switch off DI0 to DI7.
Select the homing direction with [Pr. PT45]. The
setting is shown as follows:
Address increasing direction: -11
Address decreasing direction: -43
Set the rotation speed until the Z-phase is detected.
Set the rotation speed after the Z-phase is detected.
Set this to shift the home position, which is specified
by the Z-phase signal.
The acceleration/deceleration time constant of [Pr.
PT61] or [Pr. PT62] is used.
Set [Pr. PT60 Function selection T-8] to select the
parameters to be used.
Set the current position at the time of homing
completion.
