Operation
10-1 Operational Procedure
Turn ON the power supply after the correct installation and wiring to check the operation of the
individual motor and drive.
Then make the function settings as required according to the use of the motor and drive.
If the user objects are set incorrectly, there is a risk of unexpected motor operation, which can
be dangerous.
Set the objects accurately according to the setting methods in this manual.
Item Contents Reference
Mounting and 
installation
Install the motor and drive according to the installation conditions. 
(Do not connect the motor to the mechanical system before 
checking no-load operation.)

Wiring and 
connections
Connect the motor and drive to the power supply and peripheral 
equipment.
Specified installation and wiring conditions must be satisfied, 
particularly for models conforming to the EC Directives.
Chapter 4, 4-2
Preparing for 
operation
Check the necessary items and then turn ON the power supply.
Check on the display to see whether there are any internal errors in

Trial operation
First, check motor operation with no-load. Then turn the power 
supply OFF and connect the motor to the mechanical system.
When using a Servomotor with an absolute encoder, set up the 
absolute encoder. 
Turn ON the power supply again, and check to see whether 
protective functions, such as the immediate stop and operational 
limits, are functioning properly.
Check operation at both low speed and high speed using the 
system without a workpiece, or with dummy workpieces.
