Regen braking must be dimensioned according to the application.
For most applications, a 15 Ω/100 W resistor
is sufficient. If multiple motor modules are driven with one intermediate circuit supply, it is possible to equip only
one module with regen braking. The recommended regen resistor is available at SIGMATEK under the article
number 20-014-061-Z1.
Attention Hot Surface!
Note that the brake chopper heats up considerably during operation.
Attention: During operation and also a few minutes after operation there is
a risk of combustion when touching the brake chopper surface!
