6.1 Checking the R-axis spline belt
There are four R-axis spline belts. Check the condition of each belt.

R-axis spline belt checkpoints
• Is the belt becoming frayed due to belt wear or chipping?
• Is the belt splitting due to cracks or deterioration?
• Is the belt tension too loose? Is the belt itself loose?

CAUTION
If trouble occurs with an R-axis spline belt, then contact YAMAHA sales representative. Disassembly and cleaning of
the spline belt by the user will void the warranty.

Maintenance of options
1. Ionizer
As the ionizer is used for a long time, the discharge needle (electrode) is worn out and deteriorates.
Additionally, the periodic cleaning work is needed to maintain the static elimination effect and ion balance.
c
CATION
The tip of the ionizer discharge needle is sharp and the voltage is applied. The power supply to the ionizer is stopped
by opening the safety cover. However, make sure not to touch the tip of the ionizer discharge needle when
performing maintenance in the machine.

• Normal operation (GOOD): Lit in blue.
• Large ion balance correction amount (+PREC, -PREC): Lit in green.
The contamination of the discharge needle advances. The discharge needle needs to be cleaned.
• Ion balance error (+ERR, -ERR) : Flashes in red.
The discharge needle may be contaminated or deteriorate significantly. The relevant error is also given on the machine side.

NOTE
The discharging performance of the ionizer changes depending on the material and shape of board and parts. The
discharge performance is not guaranteed.
