2) When P •
CDV
During operation, SON (Servo-on), LSP (Forward rotation stroke end), or LSN (Reverse rotation
stroke end) was switched off; or CR (Clear) or RES (Reset) was switched on. (Cause C)
3) When C • ∆ℓ ≠ M
Mechanical slip occurred between the servo motor and machine. (Cause B)

4.3 Startup in speed control mode

Make a startup in accordance with section 4.1. This section provides the methods specific to the speed
control mode.

4.3.1 Power on and off procedures

(1) Power-on
Switch power on in the following procedure. Always follow this procedure at power-on.
1) Switch off SON (Servo-on).
2) Make sure that ST1 (Forward rotation start) and ST2 (Reverse rotation start) are off.
3) Turn on the power.
The display shows "r (Servo motor speed)", and in 2 s later, shows data.
(2) Power-off
1) Switch off ST1 (Forward rotation start) and ST2 (Reverse rotation start).
2) Switch off SON (Servo-on).
3) Shut off the power.

4.3.2 Stop

Turn off SON (Servo-on) after the servo motor has stopped, and then switch the power off.
If any of the following situations occurs, the servo amplifier suspends the running of the servo motor and
brings it to a stop.
Refer to section 3.10 for the servo motor with an electromagnetic brake.
Operation/command
Switch off SON (Servo-on).
Alarm occurrence
EM2 (Forced stop 2) off
LSP (Forward rotation stroke end) off, LSN
(Reverse rotation stroke end) off
Simultaneous on or off of ST1 (Forward
rotation start) and ST2 (Reverse rotation
start)
≠ C
The base circuit is shut off and the servo motor coasts.
The servo motor decelerates to a stop with the command. With some alarms,
however, the dynamic brake operates to bring the servo motor to a stop. (Refer to
chapter 8.)
The servo motor decelerates to a stop with the command. [AL. E6 Servo forced stop
warning] occurs. EM2 has the same function as EM1 in the torque control mode.
Refer to section 3.5 for EM1.
It will bring the motor to a sudden stop and make it servo-locked. It can be run in the
opposite direction.
The servo motor is decelerated to a stop.
