TAPE TRANSPORT SECTION
3. CAPSTAN MOTOR CIRCUIT
The captsan motor is a DC motor which has a frequency
generator (FG) coil and is current controlled by a phase
locked loop (PLL) circuit. When a cassette is loaded in the
deck after the power switch is turned on, the switch $693
turns on and the servo circuit operates and starts rotation
of the motor.
VRI1 is used to set the motor speed (tape speed) when the
PITCH CONT switch is off, that is, for ordinary recording
or playback. Except in the REC mode, the tape speed
when the PITCH CONT switch is on (for playback) can be
varied +6 %or more of the rated value by means of R691
(pitch control VR). WR2 adjusts the tape speed to the
rated speed when R691 is set to the center position. The
pinch control function does not operate during recording.
