14.3.4 Test operation mode in MR Configurator2
CAUTION
The test operation mode is designed for checking servo operation. It is not for
checking machine operation. Do not use this mode with the machine. Always use
the linear servo motor alone.
If the servo motor operates abnormally, use EM2 (Forced stop 2) to stop it.
POINT
The content described in this section indicates the environment where the servo
amplifier and a personal computer are directly connected.
When the test operation mode is selected with the test operation select switch
(SW2-1), the SSCNET III/H communication for the servo amplifier in the test
operation mode and the following servo amplifiers is blocked.
By using a personal computer and MR Configurator2, you can execute the positioning operation, the output
signal (DO) forced output, and the program operation without connecting the servo system controller.
(1) Test operation mode type
(a) Positioning operation
Positioning operation can be performed without using the servo system controller. Use this operation
with the forced stop reset. This operation may be used independently of whether the servo is on or
off and whether the servo system controller is connected or not.
Exercise control on the positioning operation screen of MR Configurator2.

(b) Output signal (DO) forced output
Output signals can be switched on/off forcibly independently of the servo status. This function is
used for output signal wiring check, etc. Exercise control on the DO forced output screen of MR
Configurator2.
(c) Program operation
Positioning operation can be performed in two or more operation patterns combined, without using
the servo system controller. Use this operation with the forced stop reset. This operation may be
used independently of whether the servo is on or off and whether the servo system controller is
connected or not.
Exercise control on the program operation screen of MR Configurator2. For details, refer to Help of
MR Configurator2.
Operation Screen control

Pause Click "Pause".
Stop Click "Stop".
Forced stop Click "Forced stop".
(2) Operation procedure
1) Turn off the power.
2) Turn "ON (up)" SW2-1.
Set SW2-1 to "ON (up)".

Turning "ON (up)" SW2-1 during power-on will not enable the test operation mode.
3) Turn on the servo amplifier.
When initialization is over, the display shows the following screen.

4) Start operation with the personal computer.
14.3.5 Operation from controller
The linear servo can be used with any of the following controllers.
Servo system controller Model
Motion controller R_MTCPU/Q17_DSCPU
Simple motion module RD77MS_/QD77MS_ /LD77MS_
14. USING A LINEAR SERVO MOTOR

(1) Operation method
For the system using the incremental linear encoder, the magnetic pole detection is automatically
performed at the first servo-on after the power-on. For this reason, when performing the positioning
operation, create the sequence which surely confirms the servo-on status as the inter lock condition of
the positioning command.
Also, some parameter settings and the home position return type differ according to the controller type.
(2) Servo system controller setting
(a) Setting precautions
The following parameters will be enabled by cycling the servo amplifier power after the controller
writes the parameters to the servo amplifier.
