6. Reinstall the Multi and Axis Unit PCBs, as necessary. Ensure that the boards are properly
seated.
7. Ensure that the Main Unit and Axis Unit are not located near any strong electrical or
magnetic fields.
8. Verify correct input voltages and ensure the power cables are properly connected.
9. Turn on the power. If problem still exists, exchange the tool cables with a known good set.
A spare set of cables is normally provided with each System.
10. If problem still exists, replace the affected tool. (Refer to Section 8.3)
11. If problem still exists, replace the affected AXIS UNit. (Refer to Section 8.3)
12. If problem still exists, replace the Multi PCB. (Refer to Section 8.3)
13. If problem still exists, replace the entire Main Unit. (Refer to Section 8.3)
9.3.3 Preset Spindle does not exist
<ERROR DESCRIPTION>
The System Preset spindle number does not match the connected Axis Unit's spindle number
dip switch setting.
<CHECK ITEMS>
1. Verify that the MACHINE CONFIGURATION / SET SEQUENCE / SET PARAMETER
screens match the physical machine configuration.
2. Re-enter the data on the MACHINE CONFIGURATION / SET SEQUENCE / SET
PARAMETER Screens or reload the Preset files from the PRESET FILE UTILITY screen.
3. Turn off the power. Remove the FC386 and Multi PCBs from the Main Unit, and verify
compatibility of software between the two (2) circuit boards. This may be of concern if a
board has been replaced.
4. Verify correct installation of all removable IC chips on both the FC386 and Multi PCBs.
5. Reinstall the FC386 and Multi PCBs. Ensure that the boards are properly seated.
6. Ensure that the Main Unit is not located near any strong electrical or magnetic fields.
7. Check Main Unit input voltage and power cable connection.
8. Check the Axis Unit input voltage (3-pHASE) and power cable connection.
9. Verify the Axis Unit dip switch setup. (Refer to Section 4.9)
10. If problem still exists, replace the affected Axis Unit. (Refer to Section 8.3)
11. If problem still exists, replace the entire Main Unit. (Refer to Section 8.3)
9.3.4 CONTROLLER EEPROM WRITE ABNORMAL
<ERROR DESCRIPTION>
Data write error occurred while communicating to the Multi PCB EEPROM.
<CHECK ITEMS>
1. Verify that the MACHINE CONFIGURATION / SET SEQUENCE / SET PARAMETER
screens match the physical machine configuration.
2. Re-enter the data on the MACHINE CONFIGURATION / SET SEQUENCE / SET
PARAMETER Screens or reload the Preset files from the PRESET FILE UTILITY screen.
3. Turn off the power. Remove the FC386 and Multi PCBs, and verify compatibility of
software between the two (2) circuit boards. This may be of concern if a board has been
previously replaced.
4. Verify correct installation of all removable IC chips on both the FC386 and Multi PCBs.
