Referring to the effective braking torque
7)
Referring to the nominal braking torque
The stated switching times can only be achieved using the respective correct electrical wiring. This also refers to the
protection circuit for brake control and the response delay times of all control components.
The use of varistors for spark quenching increases the DC-side switching times.
