low speed -P9-13 (homing low speed), stop immediately when encountering the rising edge of
deceleration point (origin) signal.
(a2) Z phase number (P9-11.0) is 0 and mechanical offset (P9-19, P9-20) is not 0:
During the operation of continuing to search the rising edge of deceleration point (origin) signal at low
speed -P9-13 (homing low speed), stop the machine immediately after encountering the rising edge of
deceleration point (origin) signal. After the motor is completely stopped, the motor will run a
quantitative pulse (P9-19, P9-20) at the set speed P9-12 (homing high speed) according to the set
number of mechanical offset pulses and direction (either positive direction or negative direction), then
the motor stops.
(a3) Z phase number (P9-11.0) is 1 and mechanical offset (P9-19, P9-20) is 0:
During the operation of continue to search the rising edge of deceleration point (origin) signal at low
speed -P9-13 (homing low speed), continue to run after encountering the rising edge of deceleration
point (origin) signal, and then find the first Z-phase signal and stop immediately.
(a4) Z phase number (P9-11.0) is 1 and mechanical offset (P9-19, P9-20) is not 0:
During the operation of continue to search the rising edge of the deceleration point (origin) signal at
low speed -P9-13 (homing low speed), continue to operate after encountering the rising edge of the
deceleration point (origin) signal, then find the first Z-phase signal and stop immediately. After the
motor stops completely, according to the set number of mechanical offset pulses and direction (either
positive direction or negative direction), the motor goes through a quantitative pulse (P9-19, P9-20) at
the speed P9-12 (homing high speed), and then the motor stops.
(b) When the motor starts to move, the signal of origin switch (deceleration point) is valid (P5-64
= 0-invalid, 1-valid), and the reverse overtravel switch is not triggered in the whole process
(NOT) (P5-23).
The servo motor directly forward searches for the falling edge of the deceleration point (origin) signal
at low speed P9-13 (homing low speed). If it encounters the falling edge of the deceleration point
(origin) signal, it will reverse (i.e. negative direction), and continue to search for the rising edge of the
deceleration point (origin) signal at low speed -P9-13 (homing low speed). The next action of returning
to origin can be divided into four cases:
(b1) Z phase number (P9-11.0) is 0 and mechanical offset (P9-19, P9-20) is 0:
In the process of negative acceleration or negative constant speed operation, stop immediately when
encountering the rising edge of the origin signal.
