7.2.2 AC Motor Power ON
(1) Turn ON the main power supply.
=CHECK=
In this state, keep hands on the EMERGENCY STOP at all times. If the cam shaft starts to move,
shut OFF power immediately.
(2) Switch to the semi−auto mode and check the motor excites.
=CHECK=
If the motor does not excite in the semi−auto mode, check the motor driver alarm.
(3) In the semi−auto mode, when wanting to rotate the motor by operating the cam shaft from the
sub−control panel, check the cam shaft turns in the normal direction and stops roughly after 1
revolution.
=CHECK=
x If the cam shaft turns in reverse, check Cn−02 bit of the motor driver to set to “0“.
x If the cam shaft does not turn at all, check the motor driver alarm display.
x Check the cam shaft’s relation with the X−Y table while turning.
(4) Working from the sub−control panel, check shifting across all 4 speeds.
7.2.3 Manual Mode Movement Check
(1) Set the machine to the manual mode. While turning the hand wheel to move the cam shaft, check
the hand wheel turns smoothly and without sticking.
=CHECK=
x If the hand wheel sticks or is hand to turn, check Cn−01 bit of the motor driver.

7.2.4 Semi−auto Mode Movement Check
(1) Adjust origin stop timing
In the semi−auto mode, turn the cam shaft 1 turn. Check the digital sequence timer stops at the
origin (358q −10q). If it does not stop at its origin. adjust the timer.

x Values ( ) are required to fine adjust.
x Adjust Cn−17 if the motor oscillates after the table has stopped.
x Use the motor driver as follows:
X axis: SGDA−02ASY25, Y axis: SGDA−04ASY25, Z axis (40/62−feeder):
SGDA−08ASY120, Z axis (80−feeder): CACR−DR15BA13SY8, Cam shaft:

x Adjust the offset of Cn−00−003 via the digital operator. (Refer to ‘7.3’.)
x Values marked with an asterisk show new parameters corresponding to the positioning delay error.
x After setting Cn−01 and Cn−0A, turn OFF the power to the machine.
