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"

The figure below illustrates the connection between power dissipation and out‐
rent
put current, depending on the switching frequency f
controller. See also Parameter Description "P-0-0001, Switching frequency of
the power output stage".
In addition, take the power at the braking resistor and the power
consumption of the control section into account. Both powers are
not contained in the figure.
