approximately 2.4Ω.

 

Replace the faulty motor with a new one.

 

• Refer to the block diagram showing the cable connection and check to

 

see if connection from the Y-axis motor to the main PCB is proper.

 

• Replace the main PCB with a new one.

 

 

The following errors frequently occur.

• Replace the main PCB with a new one.

• Lower shaft memory error

 

• ERROR E5 to ERROR FF

• Refer to the block diagram showing cable connections and check to

 

see that other cables are connected to the head switch PCB and the

 

head PCB and the head PCB properly.

transformer are proper.

 

• Check fuse F4 on the power supply PCB in the power supply base.

 

If it is blown, replace it with a new one. The 50v circuit is faulty if the

 

fuse is blown immediately after turning on the power even after

 

replacing the fuse.

 

 

Jump solenoid does not operate.

• Check to see if connection from the jump solenoid to connector P10 of

 

the head PCB is proper.

 

• Check the resistance value of the jump solenoid which does not operate

 

with the connector section. The normal resistance value is

 

approximately 56Ω.

 

If it is faulty, replace the solenoid with a new one. In this case, the

 

head PCB may also be faulty. Also replace the head PCB with a new

 

one if it does not operate properly even after replacing the solenoid.

 

• Refer to the block diagram showing the cable connections and check

 

to see if connection from connector P12 of the head PCB to connectors

 

P7, 8, 13, 14, 15, and 16 on the power supply PCB in the control box is

 

proper.

 

• Replace the head PCB with a new one.
