Note: 1.When installing DC reactor, make sure to dismantle the short connector between terminal P1 and (+).
2. NPN or PNP transistor signal can be selected as input of multi-function input terminal (X1~X5/PUL) . Inverter built-in power supply
(+24V terminal) or external power supply (PLC terminal) can be chosen as bias voltage. Factory setting '+24V' short connect with
'PLC', which locates between RJ45 and terminals.
3. Analog monitor output is the special output for meters such as frequency meter, current meter and voltage meter. It can't be used for
control operations such as feedback control.
4. As there are multi pulse styles, please refer to the line connect mode description details.
