Resistor braking
110
P
brcont
The drive and the chopper will withstand this continuous braking power. The braking is considered continuous if the
braking time exceeds 30 s.
Note: Check that the braking energy transmitted to the specified resistor(s) in 400 seconds does not exceed
E
R
.
R
Resistance value for the listed resistor assembly.
Note:
This is also the minimum allowed resistance for the brake
resistor.
E
R
Short energy pulse that the resistor assembly withstands every 400 seconds. This energy will heat the resistor
element from 40 °C (104 °F) to the maximum allowable temperature.
P
Rcont
Continuous power (heat) dissipation of the resistor when placed correctly. Energy
E
R
dissipates in 400 seconds.

22 kW with standard 22 ohm resistor and 33 kW with 32…37 ohm resistor
All braking resistors must be installed outside the converter module. The SACE brake resistors are built in an IP 21 metal
housing. The SAFUR brake resistors are built in an IP 00 metal frame.
Note:
The SACE and SAFUR resistors are not UL
listed
