5.12.1
Use of Internal Regeneration Brake Resistor
This drive essentially has internal regeneration brake resistor depending on its capacity. The integrated
regeneration brake resistors depending on the drive capacity are as follows:
Drive capacity
Internal resistor
value
Internal resistor capacity
1kW
40
Ω
100W
3.5kW
12.6
Ω
150W
5kW
6.8
Ω
120W
7.5kW
6.8
Ω
240W
When using the regeneration brake resistor installed in the drive, make sure to observe the order below
for configuration:
1. Wiring regeneration brake resistor.
-
Check to see if the terminals B and BI are short-circuited (short-circuited at factory setup, 1
kW or less).

2. Configuring regeneration brake resistor (0x2009)
-
Configure to use the regeneration brake resistor integrated into the drive (0x2009 = 0).
-
Basically, the resistor is attached on the rear of the drive heat sink.
-
Initial Value: 0
3. Check the internal regeneration brake resistor value and capacity
