8.1.8 Operating Command via RS485 Communication
8.1.9 Rotating Direction Selection via –10 to +10[V] Input of V1 Terminal
Motor runs in Forward direction when input voltage to V1-CM is between 0 and 10[V]
and FWD RUN command is active. When input voltage polarity is reversed to –10 to
0[V] during FWD RUN, motor decelerates to stop and runs in reverse direction.
