Connection Diagram
The connection diagram of the Inverter is shown in Fig 2.2.
When using the Digital Operator/Monitor, the motor can be operated by wiring only the main circuits.
Fig 2.2 Connection Diagram (Model CIMR-L7C43P7 Shown Above)
Note:
1.Main circuit terminals are indicatied with double circles and
control circuit terminals are indicatied with a single circles
2.The output current capacity of the +V terminal is 20mA
3.Sequence input signal S1 to S7 and BB are labelled for sequence
connections for no-voltage contacts or NPN transistors as the
default setting.
4.The master frequency reference is set to a voltage input reference
as the default setting.
