Cable Length between Inverter and Motor
Cable Length between Inverter and Motor
Radio noise is generated from the Inverter as well as from the input and output lines. To reduce radio
noise,install noise filters on both input and output sides, and also install the Inverter in a totally
enclosed steel
box.
The cable between the Inverter and the motor should be as short as possible.

Ground Wiring
Ground Wiring
Always use the ground terminal of the 200 V Inverter with a ground resistance of less than 100
Ω and
that of the 400 V Inverter with a ground resistance of less than 10 Ω.
Do not share the ground wire with other devices, such as welding machines or power tools.
Always use a ground wire that complies with technical standards on electrical equipment and
minimize
the length of the ground wire.
Leakage current flows through the Inverter. Therefore, if the distance between the ground electrode
and the ground terminal is too long, potential on the ground terminal of the Inverter will become
unstable.When using more than one Inverter, be careful not to loop the ground wire.

Connecting the Braking Resistor (ERF)
Connect the Braking Resistor Unit and Braking Unit to the Inverter as shown in the Figure 3.15.

Braking resistor
The braking resistor connection terminals are
B1 and B2. Do not connect to any other terminals.
Connecting to any terminals other than
B1 or B2 can cause the resistor to overheat,
resulting in damage to the equipment.
