Published date: 22 June 2020

Issue:
Altivar drive capacitance calculation.

Product Line:
Altivar Drives

Environment:
All serial numbers for Altivar Drives

Cause:
N/A

Resolution:
The coulombs can be calculated from the capacitance in Farads multiplied by the DC bus voltage.

Q = C * V
Q = charge in coulombs
C = capacitance in farads
V = voltage
