For more information, see Chapter 6. 4 "Terminal To Function" (TTF) programming principle. 142 AI3 signal filter time 567 (2. 2. 41, 2. 2. 4. 2) When this parameter is given a value greater than 0 the function that filters out disturbances from the incoming analogue signal is activated. Long filtering time makes the regulation response slower. See parameter ID324. 143 AI3 signal range 567 (2. 2. 39, 2. 2. 4. 3) With this parameter you can select the AI3 signal range.

If any of the inputs is selected the motoring power limit is scaled between zero and parameter ID1289. This parameter is available for NXP drives only. 0 = Not used 1 = AI1 2 = AI2 3 = AI3 4 = AI4 5 = FB Limit Scaling ID46 (monitoring value) Description of parameters 131(209) 8 300 Start/Stop logic selection 2346 (2. 2. 1, 2. 2. 1. 1) 0 DIN1: closed contact = start forward DIN2: closed contact = start reverse FWD Output frequency Stop function (ID506) = coasting t REV DIN1 DIN2 1 2 NX12K09 3 Figure 8-6. Start forward/Start reverse The first selected direction has the highest priority. When the DIN1 contact opens the direction of rotation starts the change. If Start forward (DIN1) and Start reverse (DIN2) signals are active simultaneously the Start forward signal (DIN1) has priority. 1 DIN1: closed contact = start DIN2: closed contact = reverse See below.

At low frequencies the cooling effect of the motor is reduced as well as its capacity. If the motor is equipped with an external fan the load reduction at low speeds is small. The motor thermal protection is based on a calculated model and it uses the output current of the drive to determine the load on the motor. [. . . ]
