Tip!
Switching on the motor side of the controller is only permitted for emergency switch-off.
4.2.7.3 Connection of a brake unit
• When connecting a brake unit (brake module with internal brake resistor or brake chopper
with external brake resistor) observe the corresponding Operating Instructions in any case.
Stop!
• Design the circuit so that, if the temperature monitoring of the brake unit is activated,
– the controllers are inhibited (X5/28 = LOW).
– the mains is disconnected.
• Examples:
– Chapter 4.3, “Installation of a CE-typical drive system”.

– Fig. 4-9, “Decentralized supply for DC-bus connection of several drives”. (^ 4-18)
