4. STARTUP
4 - 16
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 driver.
Test operation of the servo motor
alone in JOG operation of test
operation mode
Test operation of the servo
motor alone by commands
Test operation with the servo
motor and machine connected
In this step, confirm that the driver 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 4.5.9 for the test operation mode.
In this step, confirm that the servo motor correctly rotates at the slowest
speed under the commands from the PC or PLC...etc.
Make sure that the servo motor rotates in the following procedure.
1) Switch on SON (Servo-on). When the driver is put in a servo-on status,
RD (Ready) switches on.
2) When TC (Analog speed command) is input from the PC or PLC...etc
and RS1 (Forward rotation start) or RS2 (Reverse rotation start) is
switched on, the servo motor starts rotating. Give a low torque command
at first and check the rotation direction, etc. of the servo motor. If the
machine does not operate in the intended direction, check the input
signal.
In this step, connect the servo motor with the machine and confirm that the
machine operates normally under the commands from the PC or PLC...etc.
Make sure that the servo motor rotates in the following procedure.
1) Switch on SON (Servo-on). When the driver is put in a servo-on status,
RD (Ready) switches on.
2) When TC (Analog speed command) is input from the PC or PLC...etc
and RS1 (Forward rotation start) or RS2 (Reverse rotation start) is
switched on, the servo motor starts rotating. Give a low torque 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, check for any problems of the servo motor
speed, load ratio, etc.
3) Then, check automatic operation with the program of the PC or PLC...etc.
4.4.4 Parameter setting
When using this servo in the torque control mode, change [Pr. PA01] setting to select the torque control
mode. In the torque control mode, the servo can be used by merely changing the basic setting parameters
([Pr. PA _ _ ]) and extension setting parameters ([Pr. PC _ _ ]) mainly.
As necessary, set other parameters.
4.4.5 Actual operation
Start actual operation after confirmation of normal operation by test operation and completion of the
corresponding parameter settings.
