NOTES ON USE VS mini J7 Inverter Selection < Use a DC reactor (option) or an AC reactor (option) on the inverter power side when the inverter is connected directly to a large-capacity power transformer (600kVA and over within 10m distance) or when a phase advance capacitor is switched. Otherwise excess peak current may occur in the power feed circuit and the converter section may be damaged.
NOTES ON USE (Cont'd) VS mini J7 Peripheral Devices Installation and selection of molded-case circuit breaker On the input power side, a molded-case circuit breaker (MCCB) to protect inverter primary wiring should be installed. The inverter power-factor (depending on power voltage, output frequency, and load) must be taken into account for selecting MCCB. For standard settings, see page 36.
Noise Countermeasures The low-noise type uses high-carrier frequency PWM control, and compared to the low-carrier type tends to suffer from increased electromagnetic interference (EMI). Following are suggestions that may be effective in reducing EMI effects in your installation: • Lower the carrier frequency (constant n46) and the interference will be reduced. • A line noise filter is effective in eliminating sensor malfunction or AM radio static (see page 35).
NOTES ON USE (Cont'd) VS mini J7 Motor 25% ED (OR 15 MIN) 40% ED (OR 20 MIN) Application for Existing Standard Motors 60% ED (OR 40 MIN) 100 A standard motor driven by the inverter generates slightly less power than it does when it is driven with commercial power supply. Also, the cooling effect deteriorates in low speed range so that the motor temperature rise increases. Reduce load torque in the low speed range. Allowable load characteristics of the standard motor are shown in the figure.
