6-1 Operational Procedure
After mounting, wiring, and connecting a power supply, check the operation of the Servomotor and
Servo Drive. Then make the function settings as required according to the use of the Servomotor
and Servo Drive. If the parameters are set incorrectly, there is a risk of an unpredictable Servomotor
operation. Set the parameters according to the instructions in this manual.
Item Contents Reference
Mounting and
installation
Install the Servomotor and Servo Drive according to the installation
conditions. (Do not connect the Servomotor to the mechanical
system before checking the no-load operation.)
4-1 Installation
Conditions
Wiring and
connections
Connect the Servomotor and Servo Drive to the power supply and
peripheral devices.
Specified installation and wiring requirements must be satisfied,
particularly for models conforming to the EC Directives.
4-2 Wiring
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
the Servo Drive.
If using a Servomotor with an absolute encoder, first set up the
absolute encoder.
6-2 Preparing for
Operation
Setting functions
By means of the user parameters, set the functions according to the
operating conditions.

rameters
Trial operation
First, test operation without a load connected to the motor. Then turn
the power OFF and connect the mechanical system to the motor. If
using a Servomotor with an absolute encoder, set up the absolute
encoder and set the Motion Control Unit’s initial parameters.
Turn ON the power, and check to see whether protective functions,
such as the emergency stop and operational limits, work properly.
Check operation at both low speed and high speed using the system
without a workpiece, or with dummy workpieces.
Even without a load, the Servomotor may vibrate. If the Inertia Ratio
(Pn20) is set low, adjust the gain as required for operation.
6-5 Trial Opera-
tion
Adjustments
Manually adjust the gain if necessary. Further adjust the various
functions to improve the control performance.
