Rating for Lenze brake resistors

To decelerate greater moments of inertia or with a longer operation in generator mode an

external brake resistor is required. It converts braking energy into heat.
The brake resistors (IP20) recommended in the table are designed for a 1.5-fold

regenerative power. The cycle time is 150 s and contains a maximum braking time of 15 s

and a minimum recovery time (break) of 135 s.

ƒ

The brake resistors are equipped with a thermostat (potential-free NC contact,

switching capacity: AC 250 V, 0.5 A).

ƒ

To increase the power, brake resistors can be connected in parallel or in series.
– The resistance for the controller must not fall below the lowest permissible value.
– The thermostat of several brake resistors at a controller must always be connected

in series.
