4. STARTUP
4.4.3 Test operation
Before starting actual operation, perform test operation to make sure that the machine operates normally.
Refer to section 4.4.1 for the power on and off methods of the servo amplifier.
Test operation of servo motor alone
in JOG operation of test operation
mode
In this step, confirm that the servo amplifier and servo motor
operate normally.
With the servo motor disconnected from the machine, use the test
operation mode and check whether the servo motor correctly
rotates at the slowest speed. Refer to section 6.9 for the test
operation.
Test operation of servo motor alone
by commands
In this step, confirm that the servo motor correctly rotates at the
slowest speed under the commands from the command device.
Make sure that the servo motor rotates in the following procedure.
1) Switch on the Servo-on (SON). When the servo amplifier is put
in a servo-on status, the Ready (RD) switches on.
2) When the analog speed command (TC) is input from the
command device and the Forward rotation start (RS1) or
Reverse rotation start (RS2) is switched on, the servo motor
starts rotating. Give a low speed command at first and check
the rotation direction, etc. of the servo motor. If the servo motor
does not operate in the intended direction, check the input
signal.
Test operation with servo motor and
machine connected
In this step, connect the servo motor with the machine and
confirm that the machine operates normally under the commands
from the command device.
Make sure that the servo motor rotates in the following procedure.
1) Switch on the Servo-on (SON). When the servo amplifier is put
in a servo-on status, the Ready (RD) switches on.
2) When the analog speed command (TC) is input from the
command device and the Forward rotation start (RS1) or
Reverse rotation start (RS2) is switched on, the servo motor
starts rotating. Give a low speed command at first and check
the operation direction, etc. of the machine. If the machine
does not operate in the intended direction, check the input
signal. In the status display or MR Configurator, check for any
problems of the servo motor speed, load ratio, etc.
3) Then, check automatic operation with the program of the
command device.
