(3) Rewinder motor driver (7010R only)
This is a driving circuit to drive the rewinder motor (DC motor). The following illustration shows
a simplified circuit.
Rewinder motor ON/OFF status is controlled by DCMTR1 and DCMTR0 signals sent from pins
35 and 40 of U1 (CPU).
Motor ON:
DCMTR1=L and DCMTR0=H
Motor OFF (free): DCMTR1=L and DCMTR0=L
Braking: DCMTR1=H
(DCMTR0=L/H)
When DCMTR1 signal is “Low”, Q502 turns OFF and Q501 turns OFF. When DCMTR0 signal
is “High”, Q506 turns ON, Q505 turns OFF and, if Q503 is OFF (DCMTR1 signal is “Low”),
Q504 turns ON and the rewinder motor is turned.
Rewinder Full detection:
The form sensor (photo interrupters PS501 and PS502) on the SA, Rewinder PCB is used to
detect the diameter of wound liner (or the amount of liner) at the flange in the following four
stages. As the diameter increases, the Measure Flap Plate turns backward and engages with
PS501 and PS502.
1st stage:
PS501: ON, PS502: OFF
2nd stage:
PS501: ON, PS502: ON
3rd stage:
PS501: OFF, PS502: ON
4th stage (Full): PS501: OFF, PS502: OFF
The 1st to 3rd stages are used to control the rewinder motor speed as mentioned on the next
page. The 4th stage is the Full state.
