The maximum permissible current loading of the terminal strip X2 is 16 A per
terminal. If required, the supply voltage has to be connected in parallel!

External brake resistors
(
Stop!
The drive controller does not monitor the temperature of the external resistor.
For this purpose, additional safety measures are to be considered!
The drive controller is provided with an integrated brake resistor which is designed for a
permanent power of 10 W or for a pulse power of 200 W for 50 ms.
If higher permanent or pulse powers are required, you can connect an additional external
brake resistor to the integrated brake chopper.
If the switching threshold of the brake chopper is exceeded, both resistors are energised.
Parameter Value
Switching threshold brake chopper on Approx. 63 V
Switching threshold brake chopper off Approx. 60 V
Resistance, external > 5 W
Rated power 10 W ... 600 W
