Introduction
PA14 Selection of servo motor rotation direction (refer to section 4.1.12)
Select servo motor rotation direction relative to the input pulse train.
Parameter No. PA14
setting
Servo motor rotation direction
When forward rotation pulse is input When reverse rotation pulse is input
0 CCW CW
1 CW CCW
Forward rotation (CCW)
Reverse rotation (CW)
(5) Operation confirmation before actual operation
Before starting actual operation, perform JOG operation to make sure that the machine operates properly.
MR-JN can perform the JOG operation in the test operation mode on the operation section (four
pushbuttons). (Refer to section 5.10.)
JOG operation in the test operation
mode
(Servo motor alone)
(a) Confirm that the servo amplifier and servo motor operate properly.
With the servo motor disconnected from the machine, use the test
operation mode (JOG operation) at the slowest speed and check
whether the servo motor rotates correctly.
Operation by commands from the
controller
(Servo motor and machine are
connected)
(b) Confirm that the servo motor rotates correctly at the slowest speed
under the commands from the controller.
Make sure that the servo motor rotates in the following procedure.
1) Switch on the forced stop (EM1) and servo-on (SON). When the
servo amplifier is in a servo-on status, the ready (RD) switches
on.
2) Switch on the forward rotation stroke end (LSP) and the reverse
rotation stroke end (LSN).
3) In the position control mode, when command pulses are input
from the controller, the servo motor starts rotating. Give a low
speed command at first and check the operation direction, etc.
of the servo motor. If the servo motor does not rotate in the
intended direction, check the input signal.
4) After checking that the machine operates properly, perform the
automatic operation by the program of the controller to check for
any problem with the operation.
