1. Set jumpers on the PCB to the previous satate.
2. Check whether ROM is mounted or not and confirm version of ROM.
If ROM is not mounted or ROM series is different, remove the ROM
from the old PCB and mount it on new PCB.
3. Install the PCB to the unit and set the system to the emergency stop
state. Then turn on power and measure voltage on the PCB.
Test points Rating
+24V About 23V "4%
+15V +15V "4%
+5V +5V "2%
–15V –15V "2%
4. If the PCB mounts jumper SH, set it to SET.
(Depending on version of PCB, there is no jumper SH.)
5. Confirm that jumper S1 is set to DRIVE and turn on power.
6. Press

buttons at the same time
for more than one second to enable writing parameters.
When the display shows
FFFFF , it is a state that parameters can be
written.
7. Set parameters according to the parameter list attached to the machine.
1) When you press and hold

key, you can change the values of parameters.
8. After you have completed the setting of parameters, release the
emergency stop, rotate the spindle at a low speed to see whether
problem does not occur.
* At first, check from low speed to midium speed.
* You should be ready to press the emergency stop button to escape
from accidental problem.
9. Turn off rotation commands to make fine adjustment of the PCB.
The PCB for model 1S to 3S mounts the following volumes.
RV1 Adjusting forward rotation

Used for fine adjustment of max. speed
RV2 Adjusting reverse rotation
