4. OPERATION
4.2 Startup
WARNING
Do not operate the switches with wet hands. You may get an electric shock.
CAUTION
Before starting operation, check the parameters. Some machines may perform
unexpected operation.
Take safety measures, e.g. provide covers, to prevent accidental contact of hands
and parts (cables, etc.) with the servo amplifier heat sink, regenerative 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.
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
1) Switch off the servo-on (SON).
2) When power is switched on, the display shows "C (Cumulative feedback pulses)", and in two second
later, shows data.
(2) Test operation 1
Confirm servo motor operation by operating JOG of test operation mode at lowest speed possible. (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 section 6.5 for the setting method.
