4. OPERATION

(4) Servo-on

Switch the servo-on in the following procedure:

1) Switch on main circuit/control circuit power supply.

2) Switch on the servo-on (SON).

When placed in the servo-on status, the servo amplifier is ready to operate.

(5) Start

Using speed selection 1 (SP1) and speed selection 2 (SP2), choose the servo motor speed. Turn on

forward rotation select (DI4) to run the motor in the forward rotation (CCW) direction or reverse

rotation select (DI3) to run it in the reverse rotation (CW) direction, generating torque. At first, set a

low speed and check the rotation direction, etc. If it does not run in the intended direction, check the

input signal.

On the status display, check the speed, load factor, etc. of the servo motor.

When machine operation check is over, check automatic operation with the host controller or the like.

(6) Stop

In any of the following statuses, the servo amplifier interrupts and stops the operation of the servo

motor:

Refer to Section 3.9, (2) for the servo motor equipped with electromagnetic brake.

(a) Servo-on (SON) 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.

The base circuit is shut off and the dynamic brake is operated to bring the servo motor to a sudden

stop. Alarm AL.E6 occurs.

(d) Simultaneous ON or simultaneous OFF of forward rotation selection (RS1) and reverse rotation

selection (RS2)

The servo motor coasts.

POINT

A sudden stop indicates deceleration to a stop at the deceleration time

constant of zero.

4.3 Multidrop communication

You can use the RS-422 communication function (parameter No.16) to operate two or more servo

amplifiers on the same bus. In this case, set station numbers to the servo amplifiers to recognize the servo

amplifier to which the current data is being sent. Use parameter No. 15 to set the station numbers.

Always set one station number to one servo amplifier. Normal communication cannot be made if the same

station number is set to two or more servo amplifiers.

For details, refer to Chapter 14.
