Cautions 1. The terminal which has more than one should connect not only one terminal but all terminals.

2. Pull down resistance is connected to the input terminal. It’s not necessary that the input

terminal is connected when it isn’t used.

3. The motor part power supply terminals VM1, VM23, and VM4 are separated inside, and can

impress an individually different power supply.

4. The motor part power supply terminal of the output which is not used should impress voltage

of recommended operation condition, or should connect to GND.

In addition, if voltage is impressed to VM terminal even when an input is open, VM terminal

current (10 µAMAX) is flow at the time of standby.
