When the drawer is driven in accordance with the conditions above, the
signal waveform of the drive signal is as shown in Figure F-1.
Figure F-1. Drawer Drive Signal Waveform
Because ON time differs depending on the drawer used, set the ON time ac-
cording to the drawer specifications. However, drawers which do not meet
formulas F-1 and F-2 cannot be used.
3) Notes on using the drawers that do not satisfy the conditions described in 2)
When the values of
n1
and
n2
are determined according to the conditions
described in 2), the setting value range of
n1
is 0 to 255 and the
n1
value range
inevitably becomes 0 n1 63, and the maximum ON time is 126 ms.
If the drawer needs more than 126 ms ON time, set the ON time and OFF time
so that they can satisfy Formula C-3.
