Corrective action
• Interface unit (MR-J2M-P8B) for servo
amplifier connection fault.
• Connect the interface unit (MR-
J2M-P8B) for servo amplifier to
the base unit (MR-J2M-BU
) for
servo amplifier correctly.
• Interface unit (MR-J2M-P8B) for servo
amplifier fault.
• Replace the interface unit (MR-
J2M-P8B) for servo amplifier.

Base unit bus
error 1
• Base unit (MR-J2M-BU
) for servo
amplifier fault.
• Replace the base unit (MR-J2M-
BU
) for servo amplifier.
• Servo amplifier connection fault. • Connect the servo amplifier to the
base unit (MR-J2M-BU
) for
servo amplifier correctly.
• Servo amplifier fault.
• Replace the servo amplifier.

Base unit bus
error 2
• Base unit (MR-J2M-BU
) for servo
amplifier fault.
• Replace the base unit (MR-J2M-
BU
) for servo amplifier.

Output ground
fault
• U, V, or W of the servo amplifier
output grounded.
• Check whether the servomotor
has short-circuited.
• Correct the U, V, W wiring of the
servo amplifier.
• Replace the servomotor.
• Servo amplifier connection fault. • Connect the servo amplifier to the
base unit (MR-J2M-BU
) for
servo amplifier correctly.
• Base unit (MR-J2M-BU ) for servo
amplifier fault.
• Replace the servo amplifier.

Servo amplifier
mounting error
• Faulty parts in servo amplifier.
Any time during
operation
Immediate
stop
• Replace the servo amplifier.
• The voltage of the supercapacitor
inside the absolute position encoder
has dropped.
• Turn the power on for 2 to 3
minutes to charge the
supercapacitor, switch the power
off to on again, and set the
home position return.
• The battery voltage is low. • Turn the servo amplifier power
off, then measure the battery
voltage.
