Brake Resistor Assembly For R1 - ABB ACH580-01 Hardware Manual


Brake resistor assembly for R1...R3
Check the insulation of the brake resistor assembly (if present) as follows:
1. Check that the resistor cable is connected to the resistor, and disconnected from
the drive output terminals R+ and R-.
2. At the drive end, connect the R+ and R- conductors of the resistor cable together.
Measure the insulation resistance between the combined conductors and the PE
conductor by using a measuring voltage of 1000 V DC. The insulation resistance
must be greater than 1 Mohm.
