15. MR-E-
AG SERVO AMPLIFIER COMPATIBLE WITH ANALOG INPUT
15.3 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.
During power-on for some after power-off, do not touch or close a parts (cable etc.)
to the servo amplifier heat sink, regenerative brake resistor, the servo motor, etc.
Their temperatures may be high and you may get burnt or a parts may damaged.
Perform pre-operation checks while referring to Section 4.1. Connect the servo motor with a machine after
confirming that the servo motor operates properly alone.
Use parameter No. 0 to choose the control mode used. After setting, this parameter is made valid by
switching power off, then on.
15.3.1 Speed control mode
(1) Power on
1) Switch off the servo-on (SON).
2) When power is switched on, the display shows "r (servo motor speed)", and in two second later,
shows data.
(2) Test operation
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 6.5 for the setting method.
