Polygon motor synchronization
problem
• When the polygon motor starts, the
motor does not become stable even
after 20 s.
Polygon motor steady-state problem
• When high-speed rotation from low-
speed rotation is requested, the motor
does not become stable even after 20
s.
BD steady-state problem
• The VTC detects a BD error for 600
ms after the polygon motor rotation
has been stabilized.
