Example Regen Resistor Power Dissipation Calculation, continued
Example Step 8
Compare the ratings as follows:
Internal Regen resistor ratings of the MHDS1028N00:
P
pulse
 = 21 kW
P
continuous
 = 200W
Deceleration 1: P
pulse
 = 940W < 21 kW rating
Deceleration 2: P
pulse
 = 1258W < 21 kW rating
P
continuous
 = 231W > 200W
Requires an optional external Regen resistor be used. Select the 250W 
optional external Regen resistor or modify the profile to reduce the continuous 
power dissipated.
