(a1) Z phase number (P9-11.0) is 0 and mechanical offset (P9-19, P9-20) is 0:
Decelerate in the reverse direction (i.e. restore the reverse direction), and search for the rising edge of
NOT at the reverse low speed -P9-13 (homing low speed). In the process of reverse acceleration or
reverse constant speed operation, stop immediately when encountering the rising edge of NOT.
(a2) Z phase number (P9-11.0) is 0 and mechanical offset (P9-19, P9-20) is not 0:
Decelerate in the reverse direction (i.e. restore the reverse direction), and search for the rising edge of
the reverse overtravel switch signal (NOT) at the reverse low speed -P9-13 (homing low speed). In the
process of reverse acceleration or reverse constant speed operation, stop immediately when
encountering the rising edge of NOT. After the motor stops completely, the motor will move a
quantitative pulse at the speed P9-12 (homing high speed) according to the set number of mechanical
offset pulses and direction (it only can be positive, but it must move between the origin switch and
POT), and then the motor stops.
(a3) Z phase number (P9-11.0) is 1 and mechanical offset (P9-19, P9-20) is 0:
Continue to operate in the forward low-speed P9-13, and then stop immediately after encountering the
rising edge of the first Z-phase signal.
(a4) Z phase number (P9-11.0) is 1 and mechanical offset (P9-19, P9-20) is not 0:
Continue to operate in the forward low-speed P9-13, and then stop immediately after encountering the
rising edge of the first Z-phase signal. After the motor stops completely, the motor will move a
quantitative pulse at the speed P9-12 (homing high speed) according to the set number of mechanical
offset pulses and direction (it can be positive or negative), but it must move between the origin switch
and POT), and then the motor stops.
(b) When the motor starts to move, the reverse overtravel switch (NOT) (P5-23) is valid
The servo motor directly searches for the falling edge of the reverse overtravel switch signal (NOT) at
the forward low speed P9-13 (homing low speed). After encountering the falling edge of NOT, the next
homing action is divided into four cases:
(b1) Z phase number (P9-11.0) is 0 and mechanical offset (P9-19, P9-20) is 0:
Decelerate in reverse direction (i.e. resume reverse direction), search for the rising edge of NOT in
reverse direction at low speed -P9-13(homing low speed). During reverse acceleration or reverse
constant speed operation, stop immediately when encountering the rising edge of NOT.
