line noise precaution:
The device may malfunction if the V
DD
line noise exceeds 0.5V.
As a countermeasure, separating the V
DD
system GND (S-GND) and V
BB
system GND (P-GND) from the device GND (Pin-11) helps to reduce noise.
* Be sure to connect the unused logic input terminals (CW/CCW, M1, M2,
Reset, Sync) to V
DD
or GND.
Otherwise, the device will malfunction.
