M-35
The Scanner starts the scan motion as a Scan Sel signal (PJ16A-3) is output from
PWB-A. At the start of a scan motion and other heavy load conditions, Scanner
Motor M5 requires a large amount of current. The Current 1 or 2 signal (PJ16A-10
or 11) from PWB-A is selected accordingly to vary the amount of current supplied
to M5.
*The Current signal selection timing is controlled by software.
Current 1 H L L
Current 2 H H L
Current Approx. 0.6A Approx. 0.7A Approx. 0.9A
When the scan
speed reaches a
given level and
during return braking.
At scan start and
when the return
speed reaches a
given level.
At return start and
at scan start for low
zoom ratio
On receiving the Scan Sel signal, Motor Drive Board PWB-E applies motor drive
pulses, which are out-of-phase with each other, to M5. The motor speed is varied
by changing the width of the pulses applied to M5.
