Terminal symbols: shows main circuit; shows control circuit. * ** 1 : Connect to the momentary power loss ridethru unit. Do not connect power lines to these terminals. Normally not used.
Do not connect power lines to these terminals. The output current capacity of the + V terminal is 20 mA. Do not create a short between the + V, V, and AC control - circuit terminals. This may cause the MxC to malfunction. The wiring for a motor with a cooling fan is not required for self-cooling motors. PG circuit wiring ( i.e., wiring to the PG-B 2 Card ) is not required for control without a PG. Sequence input signals S 1 to S 12 are labeled for sequence connections ( 0 V common and Sinking Mode ) for no-voltage contacts or NPN transistors. These are the factory settings.
For PNP transistor sequence connections ( + 24 V common and Sourcing Mode ) or to provide a 24 V external power supply, refer to the Instruction Manual. * 7 : The multi-function analog output is a dedicated meter output for an analog frequency meter, ammeter, voltmeter, wattmeter, etc. Do not use this output for feedback control or for any other control purpose. The minimum load of a multi-function contact output and an error contact output is 10 mA. Use a multifunction open-collector output for a load less than 10 mA. Do not ground the AC terminal of the control circuit and do not connect it to the grounding terminal on the MxC enclosure. This may cause the MxC to malfunction. 2 3 : :
