1)
Also depending on firmware and control section; see parame‐
ter description "P‑0‑0001, Switching frequency of the power
output stage"; see "P-0-4058, Amplifier type data"; for supply
units the switching frequency is 4.2 kHz
2) 3)
Plus dissipation of braking resistor and control section; find in‐
terim values by interpolation to P_Diss_cont
