(b) Forward overtravel switch is valid when motor starts moving (POT) (P5-22)
The servo motor directly searches for the falling edge of the forward overtravel switch signal (POT) at
a reverse low speed -P9-13 (homing low speed). After encountering the falling edge of POT, 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 the reverse direction (i.e. restore the forward direction), search for the rising edge of POT
in the forward low-speed P9-13 (homing low speed), and stop immediately when encountering the
rising edge of POT during forward acceleration or forward constant speed operation.
(b2) Z phase number (P9-11.0) is 0 and mechanical offset (P9-19, P9-20) is not 0:
Decelerate in reverse direction (i.e. restore the positive direction), search the rising edge of POT at low
speed and positive direction with P9-13 (homing low speed). In the process of positive acceleration or
positive constant speed operation, stop immediately when encountering the rising edge of POT. 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 negative
direction, but it must move between the origin switch and NOT), and then the motor stops.
(b3) Z phase number (P9-11.0) is 1 and mechanical offset (P9-19, P9-20) is 0:
Continue to operate in reverse at the low speed -P9-13 (homing low speed), and then stop immediately
after encountering the rising edge of the first Z-phase signal.
(b4) Z phase number (P9-11.0) is 1 and mechanical offset (P9-19, P9-20) is not 0:
Continue to operate in the reverse direction at the low speed -P9-13 (homing low speed), 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 negative or positive, but it must
move between the origin switch and NOT), and then the motor stops.
6. Homing mode 5——reverse homing, deceleration point and origin are reverse overtravel
switch NOT (P5-23) (P9-11.2=5)
To use this mode, please connect POT, NOT.
(a) When the motor starts moving, the reverse override switch (NOT) is invalid
Firstly, the servo motor searches for the reverse overtravel switch (NOT) at reverse high speed -P9-12
(homing high speed). After encountering the rising edge of NOT, it gradually decelerates in reverse
according to the setting of P9-14 (homing acceleration and deceleration time). The servo motor
searches for the falling edge of NOT at forward low speed P9-13 (homing low speed). After
encountering the falling edge of NOT, the next homing action can be divided into four cases:
