4. OPERATION
4.2 Startup
WARNING
y Do not operate the switches with wet hands. You may get an electric shock.
CAUTION
y Before starting operation, check the parameters. Some machines may perform
unexpected operation.
y Take safety measures, e.g. provide covers, to prevent accidental contact of hands
and parts (cables, etc.) with the servo amplifier heat sink, regenerative brake
resistor, servo motor, etc. since they may be hot while power is on or for some time
after power-off. Their temperatures may be high and you may get burnt or a parts
may damaged.
y During operation, never touch the rotating parts of the servo motor. Doing so can
cause injury.
Connect the servo motor with a machine after confirming that the servo motor operates properly alone.
4.2.1 Selection of control mode
Use parameter No. 0 to choose the control mode used. After setting, this parameter is made valid by
switching power off, then on.
4.2.2 Position control mode
(1) Power on
(a) Switch off the servo on (SON) signal.
(b) When main circuit power/control circuit power is switched on, "C (Cumulative feedback pulses)"
appears on the parameter unit.
(2) Test operation 1
Using jog operation in the "test operation mode", make sure that the servo motor operates. (Refer to
Section 6.8.2.)
(3) Parameter setting
Set the parameters according to the structure and specifications of the machine. Refer to Chapter 5 for
the parameter definitions and to Sections 7.8 for the setting method.
Parameter Name Setting Description
No. 0 Select the control mode 0 Fourth digit : Position control mode
No. 2 Auto tuning 104
First digit: : Middle response (initial value) is selected.
Second digit : Ordinary machine
Third digit : Used
No. 3 Electronic gear numerator (CMX) 1 Electronic gear numerator
No. 4 Electronic gear denominator (CDV) 1 Electronic gear denominator
After setting the above parameters, switch power off once. Then switch power on again to make the
set parameter values valid.
