17. SPEED CONTROL OPERATION
17.5 Startup
17.5.1 Power on and off procedures
(1) Power-on
Switch the power on in the following procedure. Always follow this procedure at power-on.
1) Switch off the servo-on (RYn0).
2) Make sure that the forward rotation start (RYn1) and the reverse rotation start (RYn2) are off.
3) Switch on the main circuit power supply and control circuit power supply.
When main circuit power/control circuit power is switched on, the servo amplifier display shows "b01"
(if the servo amplifier has the station number of 1).
(2) Power-off
1) Make sure that the forward rotation start (RYn1) and the reverse rotation start (RYn2) are off.
2) Switch off the servo-on (RYn0).
3) Switch off the main circuit power supply and control circuit power supply.
17.5.2 Stop
If any of the following conditions occurs, the servo amplifier interrupts and stops the operation of the servo motor.
Refer to section 4.11 for the servo motor with an electromagnetic brake.
(a) Servo-on (RYn0) off
The base circuit is shut off, and the servo motor coasts.
(b) 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.
(c) Forced stop (EMG) off
The base circuit is shut off and the dynamic brake is operated to bring the servo motor to a sudden stop.
Servo forced stop warning (AE6) occurs.
(d) Forward rotation stroke end (LSP) and reverse rotation stroke end (LSN) off
The servo motor is brought to a sudden stop to become the servo-lock status. Operation in the opposite
direction is possible.
(e) Forward rotation start (RYn1) and reverse rotation start (RYn2) simultaneously on/off
The servo motor is decelerated to a stop. In this case, the servo-lock status is not made at the time of
stop.
