Optional Brake Chopper And Resistor(S) For The Acs800-01/U1 - ABB ACS800 Hardware Manual

146
Note: A resistor other than the standard resistor can be used provided that:
• its resistance is not lower than the resistance of the standard resistor.
WARNING! Never use a brake resistor with a resistance below the value specified
for the particular drive / brake chopper / resistor combination. The drive and the
chopper are not able to handle the overcurrent caused by the low resistance.
• the resistance does not restrict the braking capacity needed, i.e.,
where

• the heat dissipation capacity (E
