• Code: 159A
• Description: ATC Motor overload error
• Causes: The electric current flowing when driving the motor is irregularly large. • Irregular load • ATC Motor Assy cable is damaged. • ATC Motor Assy encoder failure • ATC Motor failure
• Remedy: Replace the ATC Motor Assy.

• Code: 159B
• Description: ATC Motor over speed error
• Causes: Detects, when accelerating/decelerating the motor, that it is being driven at an irregularly faster speed than the specified value. • Irregular load • ATC Motor Assy encoder failure • ATC Motor failure • SUB Board is damaged. • ATC Motor driver failure
• Remedy: 1. Replace the ATC Motor Assy. 2. Replace the SUB-D Board. 3. Replace the Main Board.

• Code: 159C
• Description: ATC Motor reversing error
• Causes: Detects accumulatively more than the specified number of times that it is being driven in the opposite direction to the specified driving direction. • The polarity of ATC Motor Assy cable is opposite. • ATC Motor Assy encoder failure
• Remedy: Replace the ATC Motor Assy.

• Code: 159D
• Description: ATC Motor driving time-out error
• Causes: Detects that the driving period is irregularly long. • Irregular load • Firmware becomes out of control.
• Remedy: Replace the Main Board.

• Code: 159E
• Description: ATC Motor velocity deviation error
• Causes: Detects, when accelerating/decelerating the motor, that it is being driven at an irregularly faster speed than the specified value. • Irregular load • ATC Motor Assy encoder failure • ATC Motor failure • SUB Board is damaged. • ATC Motor driver failure
