Operation after Recovery from Power Interruption

Setting range

0, 1, 2

Factory setting 0

This constant is used to select the processing to be performed after recovery from an
instantaneous power interruption.

Value

Description

Discontinues operation.

Continues operation only if power interruption is within 0.5 second.

Continues operation unconditionally (with no error output).

Note If “1” or “2” is selected to continue operation, the Inverter automatically searches

the motor speed (even when the motor is in a free-running state) and continues
smooth operation. This function is called the speed search function.

Explanation of Speed Search Function

Motor speed

Free-running state

Inverter starts operating

Carrier Frequency

Setting range

1, 2, 3, 4
(see note 1)

Factory setting 4 (10 kHz)

(see note 2)

This constant is used to set a pulse-width-modulated (PWM) carrier frequency.

Value

Carrier frequency

2.5 (kHz)

5 (kHz)

7.5 (kHz)

10 (kHz)

12.5 (kHz)

Note As the cable between the Inverter and the motor becomes longer, a high-frequen-

cy leakage current from the cable increases, causing the Inverter output current
to increase as well. This may also affect peripheral devices. To prevent this, ad-
just the carrier frequency according to the following standards:

Cable length of 50 meters or less: 10 kHz or less

Cable length of 50 to 100 meters: 5 kHz or less

Note 1. The setting range for the 400-VAC class is “1 to 5.”
