Before powering and starting operation
2.13.1

Installation

Check the following points before powering and starting operation of the converter.
Make sure that the converter is installed in a proper location and manner. (Refer to
• Confirmation of wiring
Make sure that wiring of the main circuit and the control circuit is proper.
Make sure that the installed option and peripheral devices are appropriate and the wiring of them is proper. (Refer to
57.)
2.13.2
Powering
When the charge lamp and the operation status 7-segment LED display turn ON properly after powering the converter, the
converter is ready.
The operation status LED display shows the following after powering the converter.
2.13.3
Operation
Turn ON the start signal of the inverter. The motor starts acceleration until its speed is constant. All this while, the operation
status LED display keeps displaying input power value (power driving).
Turn OFF the start signal of the inverter. The motor starts deceleration to a stop. The converter operation status changes
according to the amount of regenerative power. During regenerative driving, the regenerative drive indication (a decimal point
LED) is ON as shown below.
NOTE
• It is not a fault if noise comes from the dedicated reactor during regenerative driving of the converter (in other words, it is a
fault if noise comes despite the stop state of the converter by the Converter stop (SOF) signal).
• If needed, devise methods of reducing noise by modifying the enclosure in which the reactor is installed.
