7-2. IC201 (BA6247FP-Y) MOTOR DRIVER IC OPERATION
(DRIVER BOARD)
The elevator up/down motor connected between pin @™ and pin !• of IC201 is as M501, and the disc load/save motor connected
between pin 1 and pin !• of IC201 is as M502.
When the IC port logic is pin @™ > pin !•, pin 1 > pin !•, the rotating direction of M501 and M502 becomes normal.
between pin 1 and pin !• of IC201 is as M502.
When the IC port logic is pin @™ > pin !•, pin 1 > pin !•, the rotating direction of M501 and M502 becomes normal.
