When the motor starts and runs at constant speed, and MIx = 35 (Enable single-point positioning)
is active (level-triggered), the motor starts to move and stop at the single-point positioning position
according to the current speed and operation direction. The moving number of revolutions
depends on the current moving speed. As shown in the diagram below.
When executing the single-point positioning, the moving distance will not be larger than one
revolution if the drive has finished establishing the single revolution coordinate system.
In the process of motor’s operation and drive’s executing single-point positioning, if MIx = 35
(Enable single-point positioning) is inactive, then the drive’s single-point positioning function is
disabled. If the drive was in speed mode before executing single-point positioning, the drive starts
to accelerate to the operating speed.
For example:
Assume that Pr.11-65 = 1 and Pr.11-66 = 64464, then the single-point positioning position =
130000 [ = 1 × 65536+64464].
To position at 130000, if the current position of the load is at 0, and the motor PPR is 1024, then
the actual number of pulses for the motor is 126 revolutions and 976 pulses [ = 130000 ÷ 1024].
11-68
Homing Method
Default: 0008h
Settings 0000h–0128h
Used for establishing the coordinate system that uses accumulated multiple revolution for the
motor encoder.
How to set Pr.11-68:
For example:
Set Pr.11-68 = 012h when using homing method 4
Set Pr.11-68 = 116h when using homing method 10.
