Fig.6-87: HMD - Data of power section - Inverter
Observe that the load is almost independent of the power section
used.
Especially when using standard motors , make sure that they com‐
ply with the occurring voltage load.
Observe the information contained in the chapter “Third-Party Mo‐
tors at IndraDrive Controllers” in the Project Planning Manual of the
drive system.
Depending on the electric output frequency, the output current is
reduced for thermal protection of the power section.
The output current is reduced, when the electric output frequency
has fallen below the threshold to detect motor standstill.
