The DAMPER KIT has reached its end of specified
life.
When changing the PG, the PG SENSOR could not
detect the PG position.
The control terminal (Vre terminal) of the APG
motor driver has shorted out.
Connection failure of the APG motor.
Overcurrent to the APG motor was detected.
APG motor cable is damaged.
Irregular load
APG encoder failure
APG motor failure
The APG motor was driven at a speed faster than a
predetermined one during deceleration.
Irregular load
APG encoder failure
APG motor driver failure
The number of occurrences of reversing the APG
motor has reached a predetermined limit.
The polarity of APG motor cable is opposite.
APG motor failure
Detects that the driving period is irregularly long.
Irregular load

2. If the error still occurs, replace
the MAIN BOARD. (See
P.111)
