heated. The K value can be increased appropriately on the condition of good dissipation and should not exceed
50%. Failure to comply may result in a re due to overheating of braking resistor.
Braking frequency (D) is determined by application. Typical values of braking frequency in different applications
are listed in the Table 8-8..
