VLT ® 2800 SeriesFeedback higher than FB LOW, the feedback valueis higher than the value set in parameter 227Warning: Low feedback, FB LOW.Feedback lower than FB HIGH, the feedback valueis lower than the value set in parameter 228Warning: High current, IHIGH.Relay 123 is only used in connection with Profidrive.Reversing, The relay output is activated whenthe direction of motor rotation is anti-clockwise.When the direction of motor rotation is clockwise,the value is 0 V DC.Thermal warning, above the temperature limit ineither the motor or the frequency converter, or froma thermistor connected to a digital input.Local operation, the output is active when inparameter 002 Local/remote operation, Localoperation [1] has been selected.Out of the frequency range, the output frequencyis out of the programmed frequency range inparameters 225 and 226.Out of the current range, the motor current is out ofthe programmed range in parameters 223 and 224.Out of the feedback range, the feedback signal is outof the programmed range in parameters 227 and 228.Mechanical brake control, enables you to control anexternal mechanical brake (see section about controlof mechanical brake in the Design Guide).327 Pulse reference/feedback(PULSE REF/FB MAX)Value:150 - 67600 Hz ✭ 5000 HzFunction:This parameter is used for setting the signal valuethat corresponds to the maximum value set inparameter 205 Maximum reference, Ref MAX orto the maximum feedback value set in parameter415 Maximum feedback, FB MAX.Description of choice:Set the required pulse reference or pulse feedbackto be connected to terminal 33.328 Maximum Pulse 29(MAX PULSE 29)Value:150 - 67600 Hz ✭ 5000 HzFunction:This parameter is used for setting the signal valuethat corresponds to the maximum value set inparameter 205 Maximum reference, Ref MAX orto the maximum feedback value set in parameter415 Maximum feedback, FB MAX.NB!:Only relevant for DeviceNet. See MG90BXYYfor further information.341 Digital / pulse output terminal 46(DO 46 FUNCTION)Value:Unit ready (UNIT READY) [0]Parameter [0] - [20] see parameter 323Pulse reference (PULSE REFERENCE) [21]Parameter [22] - [25] see parameter 323Pulse feedback (PULSE FEEDBACK) [26]Output frequency (PULSE OUTPUTFREQ) [27]Pulse current (PULSE CURRENT) [28]Pulse power (PULSE POWER) [29]Pulse temperature (PULSE TEMP) [30]Function:The digital output can be used for giving the presentstatus or warning. The digital output (terminal 46) givesa 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.Description of choice:Pulse reference Ref MIN - Ref MAXAn output signal is obtained, which is proportionalto the resulting reference value in the intervalMinimum reference, Ref MIN - Maximum reference,Ref MAX (parameters 204/205).Pulse feedback FB MIN -FB MAX .An output signal is obtained, which is proportional to thefeedback value in the interval Minimum feedback, FB MIN- Maximum feedback, FB MAX (parameter 414/415).Output frequency 0-f MAX .An output signal is obtained, which is proportional tothe output frequency in the interval 0 - f MAX (parameter202 Output frequency, high limit, fMAX).✭ = factory setting.
