    LD-W-32.2 480 or 60 Hz (to be set) Load control The LD-G-32.2 for DC motors has a load control, the LD-W-32.2 for AC motors do not have this function. The load control influences the motor voltage to keep the locomotive with a set speed level at constant velocity, independent of additional loads (e.g.
  • Page 13 LD-G-32.2 and LD-W-32.2 English KI: The integral component of the load control ensures the remaining difference between the set and the present value is reduced to 0 and so for the correction of very small divergences. If the set value is too high the locomotive stutters massively while moving.

    (so-called detectors). The decoders must be designed to send the RailCom messages. When so programmed, the locomotive decoders LD-G-32.2 and LD-W- 32.2 send (continuously) the (basic, extended or consist) address to the detectors (so-called RailCom broadcast datagramm) and transfer a CV message after a DCC CV read-out command.
