Starting Up the System

DANGER
● Do not touch the switch with your hand wet. An electric shock may be caused.
● Check the parameters before starting operation. Otherwise, an unexpected operation may be made depending
● While the system is energized, or for a while after the system is turned off, the servo-amplifier radiator,
CAUTION
● Never touch the turning part of the servomotor during operation. Otherwise, you may be injured.
４.１ When You Turn On the System for the First Time
When you turn on the system for the first time, follow the instructions in this section.
４.１.１ Steps to Start Up the System
Check the parameter settings of the previously
installed modules.
Check the wiring.
Check the ambient environment.
Set up each parameter. (*1)
Use the test operation mode to make a separate test
operation of the servomotor.
(*1) (*2) (*3)
Issue commands to conduct a separate test operation
of the servomotor. (*1) (*2)
Connect the system for test operation.
Make a gain adjustment. (*1)
Start productive operation. (*2)
Stop the system.
For precautions, see page 4-2.
on the system.
regeneration resistance, servomotor, and so forth may be hot. To prevent anybody from carelessly touching
them with hand, and to prevent any components (such as a cable) from touching them, provide a cover or any
safety measures. Otherwise, a burn and/or some component damage may be caused.
View the servo amplifier display or the setup software (MRZJW3-SETUP161E) to check the parameter
settings of the MR-J2S amplifier previously installed. Write down the parameter settings.
Conduct a visual check of the wiring to Renewal Tool and the servo amplifier and servomotor to see if
the wiring is correct.
Check the ambient environment of Renewal Tool and the servo amplifier and servomotor. (See section
4.1.2.)
Set up the parameters, depending on your necessity, to select a control mode, generation option, and
so forth that you want to use. For the parameter setting, see the following materials issued by
Mitsubishi Electric:
Type A
"Guide for Replacing MR-J2S/J2M Series with J4 Series L(NA)03093", Part 2, Section 3.5
Type B
"MODEL (Servo Amplifier) MR-J4-_B_-RJ020, MODEL (Conversion Unit for SSCNET of MR-J2S-B)
MR-J4-T20 SERVO AMPLIFIER INSTRUCTION MANUAL SH(NA)030125-B", Section 5
For the test operation, disconnect the servomotor from the system. Operate the servomotor at as low
a speed as possible. Check that the servomotor turns correctly.
For the test operation, disconnect the servomotor from the system. Issue a command to the servo
amplifier to operate the servomotor at as low a speed as possible. Check that the servomotor turns
correctly.
Connect the servomotor and the system. Issue an operation command from a commanding module at
a higher hierarchy. Check the behavior of the system.
Make a gain adjustment to optimize the behavior of the system.
If you are going to use the position control mode, reset the components to the home positions as
necessary.
Issue a stop command to stop operation. At this time, observe how the servomotor stops to go back its
original status.
