(1)
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.
(2)
The resistance must be dimensioned based on its maximum power dissipation corresponding to the braking power
generated in the application. However, the permissible short-term power generated must be at least P=U2/R, mean-
ing 602/R.
Hot surface warning
A burn hazard exists with physical contact!
During operation, the surface of the brake resistor can become very hot and
remain hot sometime after operation.
Avertissement de surface chaude
Il existe un risque de brûlure par contact physique !
Pendant le fonctionnement, la surface de la résistance de freinage peut
devenir très chaude et rester chaude quelque temps après le fonctionne-
ment.
Avoid physical contact with the surface of the brake resistor, and for a signif-
icant time after operation.
Éviter tout contact physique avec la surface de la résistance de freinage et
pendant une longue période après le fonctionnement.
