VLT ® 2900 Series The digital output can be used for giving the present status or warning. The digital output (terminal 46) gives a 24 V DC signal when a given condition is fulfilled. Terminal can also be used for frequency output. Parameter 342 sets the maximum pulse frequency. 150 - 67600 Hz 5000 Hz This parameter is used for setting the signal value that corresponds to the maximum value set in parameter 205 Maximum reference, Ref MAX or to the maximum feedback value set in parameter 415 Maximum feed- back, FB MAX .

Pulse reference Ref MIN - Ref MAX An output signal is obtained, which is proportional to the resulting reference value in the interval Minimum reference, Ref MIN - Maximum reference, Ref MAX (pa- rameters 204/205). Set the required pulse reference or pulse feedback to be connected to terminal 33. Pulse feedback FB MIN -FB MAX . An output signal is obtained, which is proportional to the feedback value in the interval Minimum feedback, FB MIN - Maximum feedback, FB MAX (parameter 414/415). 150 - 67600 Hz Output frequency 0-f MAX . An output signal is obtained, which is proportional to the output frequency in the interval 0 - f MAX (parameter 202 Output frequency, high limit, f MAX ).

5000 Hz This parameter is used for setting the signal value that corresponds to the maximum value set in parameter 205 Maximum reference, Ref MAX or to the maximum feedback value set in parameter 415 Maximum feed- back, FB MAX . Pulse current 0 - I INV. . An output signal is obtained, which is proportional to the output current in the interval 0 - I INV . Programming Pulse power 0 - P M,N . An output signal is obtained, which is proportional to the present output power. Par. 342 corresponds to the value set in parameter 102 Motor power, P M,N . NB! Only relevant for DeviceNet. See MG90BXYY for further information. Pulse temperature 0 - Temp. MAX .

An output signal is obtained, which is proportional to the present heatsink temperature. 0 Hz corresponds to a heatsink temperature of less than 20° C, and pa- rameter 342 corresponds to 100° C. NB! Output terminal 46 is not available on De- viceNet.
