1-93 Thermistor SourceOption: Function:Select the input to which the thermistor (PTC sensor) should beconnected. An analog input option [1] or [2] cannot be selectedif the analog input is already in use as a reference source (se-lected in par. 3-15Reference Source 1, 3-16Reference Source2 or 3-17 Reference Source 3).This parameter cannot be adjusted while the motor is running.[0] * None[1] Analog input 53[2] Analog input 54[3] Digital input 18[4] Digital input 19[5] Digital input 32[6] Digital input 332.4. Main Menu - Brakes - Group 22.4.1. 2-0* DC-BrakesParameter group for configuring the DC brake and DC hold functions.2-00 DC Hold Current/Preheat CurrentRange: Function:50 %* [0 - 100%] Enter a value for holding current as a percentage of the ratedmotor current I M,N set in par. 1-24 Motor Current. 100% DCholding current corresponds to IM,N.This parameter holds the motor function (holding torque) orpre-heats the motor.This parameter is active ifDC hold is selected in par. 1-80Func-tion at Stop.NB!The maximum value depends on the rated motor current.NB!Avoid 100 % current for too long. It may damage the motor.2-01 DC Brake CurrentRange: Function:50% * [0 - 100 %] Enter a value for current as a percentage of the rated motorcurrent IM,N, see par. 1-24Motor Current. 100% DC brakingcurrent corresponds to I M,N.DC brake current is applied on a stop command, when the speedis lower than the limit set in par. 2-03DC Brake Cut In Speed;when the DC Brake Inverse function is active; or via the serialVLT ® AQUA Drive Programming Guide 2.
