9.7 External brake resistors
Braking greater moments of inertia or longer operation in generator mode requires the use
of an external brake resistor.
The brake resistors recommended in the table below are dimensioned to approx. 1.5 times
the regenerative power at a cycle time of 15/135s (brake/pause ratio). As a general rule,
these brake resistors meet the common requirements with regard to standard
applications.
The brake resistors are provided with a thermostat (potential−free NC contact).
