If ananalog input in this parameter is set as asource, it cannot be used for otherpurpose, for example, reference, feedback.[0] * None[1] Analog Input53[2] Analog Input54[3] Digital input18[4] Digital input19[5] Digital input32[6] Digital input331-93 Thermistor SourceOption: Function:[7] Digital input314.3 Parameters: 2-** Brakes4.3.1 2-0* DC BrakeUse this parameter group to configure DC brake and DChold functions.2-00 DC Hold/Motor Preheat CurrentRange: Function:50 %*[0 -160 %]Set the holding current as a percentage of therated motor current IM,N parameter 1-24 MotorCurrent. This parameter holds the motor function(holding torque) or pre-heats the motor. Thisparameter is active if [0] DC hold is selected inparameter 1-72 Start Function, or if [1] DC hold/pre-heat is selected in parameter 1-80 Function atStop.NOTICEThe maximum value depends on the ratedmotor current. Avoid 100% current for toolong. It may damage the motor.2-01 DC Brake CurrentRange: Function:50%*[0 -150 %]NOTICEMOTOR OVERHEATINGThe maximum value depends on the ratedmotor current.To avoid motor damage caused byoverheating, do not run at 100% for toolong.Set current as % of rated motor current,parameter 1-24 Motor Current. When speed isbelow the limit set in parameter 2-04 DC Brake CutIn Speed, or when the DC-brake inverse function isactive (in parameter group 5-1* Digital Inputs set to[5] DC-brake inverse; or via the serial port), a DC-brake current is applied on a stop command. Seeparameter 2-02 DC Braking Time for duration.2-02 DC Braking TimeRange: Function:10 s* [0 - 60 s] Set the duration of the DC-brake current set inparameter 2-01 DC Brake Current, onceactivated.Parameter Descriptions Programming GuideMG06C702 Danfoss A/S © 06/2017 All rights reserved. 454 4
