Note: 1.While install DC reactor, be 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~X8）. Inverter
built-in power supply (+24V terminal) or external power supply (PLC terminal) can be choosed as bias
voltage. Factory setting '+24V' short connect with 'PLC'.
3. Analog monitor output is special output of meters such as frequency meter, current meter, voltage meter
and etc. It can not 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.
