CAUTION
⋅
To prevent a malfunction due to noise, keep the signal cables more than 10cm away from the power cables.
⋅ Be sure to use the inverter and motor after grounding (earthing) them.
⋅ This connection diagram assumes that the control circuit is sink logic (initial setting). Refer to the instruction manual for the
connection in the case of source logic.
