IMPORTANT

1. Control circuit terminals are arranged as shown below.

2. 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 fault out or malfunction.

3. Main circuit terminals are indicated with double circles and control circuit terminals are indicated with single

circles.

4. The wiring for a motor with a cooling fan is not required for self-cooling motors.
5. PG circuit wiring (i.e., wiring to the PG-B2 Card) is not required for control without a PG.
6. Sequence input signals S1 to S12 are labeled for sequence connections (0 V common and Sinking Mode)

for no-voltage contacts or NPN transistors. These are the default settings.
For PNP transistor sequence connections (+24V common and Sourcing Mode) or to provide a 24 V exter-
nal power supply, refer to Table 2.10.

7. The master speed frequency reference can be input from a voltage signal (terminal A1) or current signal

(terminal A2) by changing the setting of parameter H3-13. The default setting is for a voltage reference
input.

8. The multi-function analog output is a dedicated meter output for an analog frequency meter, ammeter, volt-

meter, wattmeter, etc. Do not use this output for feedback control or for any other control purpose.

9. The minimum load of a multi-function contact output and an error contact output is 10 mA. Use a multi-

function open-collector output for a load less than 10 mA.

10. Do not ground the AC terminal of the control circuit. This may cause the MxC to fault out or malfunction.
