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.
