Connection Diagram
The connection diagram of the Inverter is shown in
Fig 2.2
. When using the Digital Operator, the motor
can be operated by wiring only the main circuits.
Note: The wiring of the main circuit depends on the Inverter capacity. Refer to page 2-20 for details.
* 1. Wiring sequence should shut off power to the drive when a fault output is triggered. For a 400 V Class power supply, install a step-down transformer.
* 2. Note that the Inverter is set to trigger a fault output whenever the fault restart function is activated (L5-02 = 1), then a sequence to interrupt power when
a fault occurs will result in shutting off the power to the Inverter as the Inverter attempts to restart itself.
The factory setting for L5-02 is 0 (fault output not active during restart attempt).
