Slit encoder
As the space motor rotates, it generates feedback pulse signals SPA-P and SPB-P. The Main
LSI detects the edge pulses from these signals and multiplies the frequency to output the
S720-P signals as the normalized timing to NHDC LSI to generate head drive timing.
2.1.11 Line feed
The LF motor is locked by the current supplied from +12V according to the pulse duty of the
LFCHOP-P signal during the stop period.
It is driven by +44V application by the LFOVDV-P signal for line feed operation.
