About Leakage Current of AKD Drive | 17 Aug 2017 | |

About Leakage Current of AKD Drive

Hello.

We read the manual and we understood about the leakage current when mains voltage is 400V.

But we don't understand how to measure the leakage current when mains voltage is 240V.

We'll look forward to your answer.

Thank you.

Section 7.17.1 of the AKD Installation Manual states:
Ileak = n x 20 mA + L x 1 mA/m at 8 kHz clock frequency at the output stage

Ileak = n x 20 mA + L x 2 mA/m at a 16 kHz clock frequency at the output stage
(where Ileak=leakage current, n=number of drives, L=length of motor cable)
*** At other mains voltage ratings, the leakage current varies in proportion to the voltage ***

Based on the statement above, 240/400 = 0.6. Use the formula above then take 60% of that value for the 240V value of leakage current.
