scription "P‑0‑0001, Switching frequency of the power output stage"; see
"P-0-4058, Amplifier type data"
2) 3) plus dissipation of braking resistor (at HMV, HCS) and control section
(at HMx, HCS); find interim values by interpolation to P_Diss_cont
4) HMV, HCS: plus dissipation of braking resistor, control section; KSM:
plus rated power consumption control voltage input
5) 6) see fig. "Air intake and air outlet at drive controller"

CAUTION
Property damage due to temperatures higher than 105 °C!
Comply with indicated minimum distances!
