Motorless Operation In Controller - Mitsubishi Electric MR-J3-B Instruction Manual

4. STARTUP

4.5.2 Motorless operation in controller

(1) Motorless operation
Without connecting the servo motor, 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.
For stopping the motorless operation, set the selection of motorless operation to [Invalid] in servo
parameter setting of servo system controller. Motorless operation will be invalid condition after switching on
power supply next time.

Load torque
Load inertia moment 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:
Encoder error 1 (16)
Encoder error 2 (20)
Absolute position erasure (25)
Battery cable breakage warning (92)
(2) Operating procedure
1) Switch off servo amplifier
2) Set parameter No.PC05 to "1", change test operation mode switch (SW2-1) to normal condition side
"Down", and then turn on the power supply.
3) Perform motor-less operation with the personal computer.
The display shows the following screen:
