※Note: Braking resistor : W= ( Vpnb * Vpnb ) * ED% / Rmin 
1. W: The power consumption of braking action 
. Vpnb: The voltage of braking action (220V=380VDC, 440V=780VDC) 
. ED%: The effective period of braking action 
4. Rmin: braking resistor minimum value (ohms)
 
 
 
6.6 Copy Unit(JN5-CU) 
The copy unit is used to copy an inverter parameter setup to another inverter. The copy unit saves time in 
applications with multiple inverters requiring the same parameter setup
