4.5.2 Motor-less operation in controller

POINT

Use motor-less operation which is available by making the servo system

controller servo parameter setting.

Connect the servo system controller to the servo amplifier before the motor-less

operation.

The motor-less operation is not used in the fully closed loop control mode, linear

servo motor control mode, and DD motor control mode.

(1) Motor-less operation

Without connecting the servo motor to the servo amplifier, output signals or status displays can be

provided in response to the servo system controller commands as if the servo motor is actually running.

This operation may be used to check the servo system controller sequence. Use this operation with the

forced stop reset. Use this operation with the servo amplifier connected to the servo system controller.

To stop the motor-less operation, set the motor-less operation selection to "Disable" in the servo

parameter setting of the servo system controller. When the power supply is turned on next time, motor-

less operation will be disabled.

(a) Load conditions

Load item Condition

Load torque 0

Load to motor inertia ratio [Pr. PB06 Load to motor inertia ratio/load to motor mass ratio]

(b) Alarms

The following alarms and warning do not occur. However, the other alarms and warnings occur as

when the servo motor is connected.

[AL. 16 Encoder initial communication error 1]

[AL. 1E Encoder initial communication error 2]

[AL. 1F Encoder initial communication error 3]

[AL. 20 Encoder normal communication error 1]

[AL. 21 Encoder normal communication error 2]

[AL. 25 Absolute position erased]

[AL. 92 Battery cable disconnection warning]

[AL. 9F Battery warning]

(2) Operation procedure

1) Set the servo amplifier to the servo-off status.

2) Set [Pr. PC05] to "_ _ _ 1", turn "OFF (down: normal condition side)" the test operation mode

switch (SW2-1), and then turn on the power supply.

Set SW2-1 to "OFF (down)".

3) Start the motor-less operation with the servo system controller.

The display shows the following screen.

The decimal point blinks.
