4. OPERATION
(f) Zeroing
Perform zeroing as required. Refer to Section 4.4 for zeroing types. A parameter setting example
for dog type zeroing is given here.
Parameter
No.8 Zeroing type
No.9 Zeroing speed
No.10 Creep speed
No.11 Zero shift distance
No.42 Zeroing position data
No.43 Moving distance after proximity dog
After setting the above parameters, switch power off once. Then switch power on again to make the
set parameter values valid.
Set the input signals as listed below and switch on the forward rotation start (ST1) to execute
zeroing.

(h) Stop
In any of the following statuses, the servo amplifier interrupts and stops the operation of the servo
motor.
When the servo motor used is equipped with an electromagnetic brake, refer to Section 3.9 (3).
Note that forward/reverse rotation stroke end (LSP/LSN) off has the same stopping pattern as
described below.
1) Servo on (SON) OFF
The base circuit is shut off and the servo motor coasts.
2) Alarm occurrence
When an alarm occurs, the base circuit is shut off and the dynamic brake is operated to bring the
servo motor to a sudden stop.
3) Emergency stop (EMG) OFF
The base circuit is shut off and the dynamic brake is operated to bring the servo motor to a
sudden stop. Alarm A.E6 occurs.
4) Forward/reverse rotation stroke end (LSP/LSN) OFF
The servo motor is brought to a sudden stop and servo-locked.
