Calculation example
The known values are:
• Average braking power: 144W
• Deceleration ramp: 2s
• 200 brake applications per hour
Calculating the energy from the power of the deceleration ramp:

For the deceleration ramp of 2s, you can use deceleration ramp [3] (0.2s) in the dia-
gram. Use the characteristic curve with the shorter deceleration ramp because a
shorter deceleration ramp means more braking energy.
The diagram permits 290 J of braking energy for the 0.2 s deceleration ramp and
200cycles per hour. In this case, the required 288J can be dissipated via BW1.
11.4.3 External braking resistor
Operation with external braking resistor is necessary for applications with a large
amount of regenerative energy.
The following table shows the external braking resistors.
