To do this, set P0719=0 (remote selection of command / setpoint source) and define the command sources (P1113) individually. This function does not disable the "reverse" command function; rather, a reverse command causes motor to run in the normal direction as described above P1120 Ramp-up time Time taken for motor to accelerate from standstill up to maximum motor frequency (P1082) wh

The shielding should have the lowest possible HF impedance and must be continuous • Use only shielded cables for the signal, control and data lines (shielded twisted pair) • The HF transfer resistance at the connecting points between shielding and housing should be kept as low as possible • Connect the shielding of motor and control cables to ground at both ends. For that purpose, use EMC cable fittings (EMC fittings, EMC cable clamps, EMC terminals and similar that ensure 36

• Siemens SED2, 22/80 Siemens Building Technologies Commissioning Guide CM1G5192en HVAC Products 5 Electrical installation 26.02.2003 5.3.3 External motor overload protection During operation below nominal speed, the cooling effect of the fan fitted to the motor shaft is reduced. For this reason, most motors require derating if operated continuously at low frequencies. To ensure that motors are pro- tected from overheating under these conditions, they must have a built-in PTC temperature sensor or a Klixon thermal switch which is to be connected to the VSD control terminals 14 and 15 according to the diagrams shown here. 14 15 SED2 Control terminals 5192Z11en 15 1 k Ω Klixon N.C. 14 5192Z11en SED2
