MEMO
of a stand-alone option connected to the DC terminals P/+, N/-.
Choose the size of the wires connected to the motor connection
terminals so that a voltage drop due to the wires is less than 4V.
The minimum wire size in the above selection table assumes that
the wiring length is less than 20m.
NOTICE
A voltage drop can be found by the following expression:
Line voltage drop (mV) =
Use the ground cable which is as thick as possible.
