The drive signal waveform generated when the drawer is driven according to the above
conditions is shown in Figure D-1.

Figure D-1 Drawer Drive Signal Waveform (Formulas D-1 and D-2)
The ON time depends on the specifications of the drawer used. Be sure to check the drawer
specifications and set a suitable time. To use a drawer that does not meet the conditions of
Formulas D-1 and D-2, see the following section.
3) Using a drawer that does not meet the conditions in 2)
Setting the values of t1 and t2 according to the conditions in 2) results in a maximum ON time
of 126 ms (0 ≤ t1 ≤ 63), since the setting ranges of t1 and t2 are 0 to 255. To use a drawer
that requires an ON time exceeding 126 ms, the following conditions must be met:
≤ 0.2 ..................................................................Formula D-3
α: other sequence processing time
NOTE: α is the period when drawer-driving is prohibited from the OFF time until the next ON
time.
