Adr. min max defaultENTERPROG.R/WStepRelease of Direction of Rotation In case of analog setpoint value setting and set value-dependent setting of directionof rotation (oP.0 = 2) no Low Speed (LS) condition is available. Therefore followingmeasures must be taken in order for the braking control to work:- adjust di.20 to „2“ (release of direction of rotation)- the release signal is given by adjusting any chosen direction of rotation at the terminalstripor- digital with any chosen direction of rotation (oP.3 = „1“ oder „2“)The direction of rotation is only released. The adjustment is still done by way of thesetpoint value.Used ParametersPn.51 2233h 4 4 - 0 2 1 0 -Pn.52 2234h 4 4 - 0,00 100,00 s 0,01 s 1,00 s -Pn.53 2235h 4 4 - 0,00 100,00 s 0,01 s 1,00 s -Pn.54 2236h 4 4 - -50,00 Hz 50,00 Hz 0,0125 Hz 2 Hz -Pn.55 2237h 4 4 - 0,00 100,00 s 0,01 s 1,00 s -Pn.56 2238h 4 4 - 0,00 100,00 s 0,01 s 1,00 s -Pn.57 2239h 4 4 - -50,00 Hz 50,00 Hz 0,0125 Hz 2 Hz -Pn.58 223Ah 4 4 - 0 100 % 1 % 0 % -Starting Frequency (Pn.54)Stopping Frequency (Pn.57)The adjustable starting and stopping frequencys stands in direct connection with therequired holding torque. The presetting according to following formula applies to therated motor torque:(no-load motor speed-rated motor speed) x rated motor frequencyStart-/Stop frequency= rated motor speed(1500 rpm - 1420 rpm ) x 50HzExample: = 2,67 Hz1420 rpmThe direction in which the holding shall be effective is defined by the sign of thefrequencies. The parameters are set programmable.
