Chapter 4. Inverter Operation

4.1 Direction of operating Inverter with caution

- Control power should be supplied prior to main power to operate inverter.

(1) Control power is supplied by putting MCCB1

within controller panel.

(2) Set operational mode and operating conditions using the operator of front inverter controller

panel before supplying main power. (Refer to 4.3)

4.2 Inverter operational mode

N5000 inverter is a Cascaded H-bridge voltage type inverter that generates 3-phase voltage

output by connecting single-phase inverters (Cell unit) serially.

4.2.1 Self-operation by operator

Set self-operation mode in the front operator. RUN and STOP operations can be implemented

without superior command in this case. Self-operation mode is used for the test purpose. (Refer to

4.3)

4.2.2 Remote control operation

Set the operational mode to remote control mode in front control panel. External speed, RUN, and

STOP commands can activate inverter. Settings of the inverter cannot be changed through installed

operator in the remote control mode.

4.2.3 Input/output related operation

(1) Inverter MODE signal: If K1 VCB of input VCB board is closed, input VCB board sends inverter

MODE signal to the inverter board.
