6.7.4 Sub-mounted braking resistors without overtemperature protection
• Sub-mounted braking resistors are only available for liquid-cooled devices.
• Terminal PB is not available for this device version.
ATTENTION
Sub-mounted braking resistors are not suitable to convert large
amounts of regenerative energy into heat. They are intended to inter-
cept regenerative peaks.
6.8 Temperature switch braking resistor, mains and motor choke
6.8.1 General instructions
The following must be observed when wiring the temperature switches of the braking
resistor, mains and motor choke:
• All cables must be laid separately from each other.
• If the various temperature switches are connected in series, EMC interference
from the motor side can be coupled back to the input. => Wiring.
• Chapter => Wiring Diagrams contains examples of how the temperature switches
are connected to the control board.
• The used digital inputs must be parameterized to external error.
