Selection of 8 preset references viathe digital terminals.Pulse referenceA pulse frequency signal transmitted to the digital inputs(terminal 29 or 33).RefMAXDetermines the relationship between the reference input at100% full scale value (typically 10 V, 20 mA) and theresulting reference. The maximum reference value is set inparameter 3-03 Maximum Reference.RefMINDetermines the relationship between the reference input at0% value (typically 0 V, 0 mA, 4 mA) and the resultingreference. The minimum reference value is set inparameter 3-02 Minimum Reference.1.6.5 MiscellaneousAnalog inputsThe analog inputs are used for controlling variousfunctions of the frequency converter.There are 2 types of analog inputs:Current input, 0–20 mA, and 4–20 mAVoltage input, -10 V DC to +10 V DC.Analog outputsThe analog outputs can supply a signal of 0–20 mA, 4–20mA.Automatic motor adaptation, AMAThe AMA algorithm determines the electrical parametersfor the connected motor at standstill.Brake resistorThe brake resistor is a module capable of absorbing thebrake power generated in regenerative braking. Thisregenerative brake power increases the DC-link voltageand a brake chopper ensures that the power is transmittedto the brake resistor.CT characteristicsConstant torque characteristics used for all applicationssuch as conveyor belts, displacement pumps, and cranes.Digital inputsThe digital inputs can be used for controlling variousfunctions of the frequency converter.Introduction Programming GuideMG20OB02 Danfoss A/S © 05/2018 All rights reserved. 51 1
