LEROY SOMER OPTION 1 | 1292 | ! 3.6 7 | Réf. 313 - 03%/a - 10.89 VTU.N Unidirectional three phase speed controller for D.C. motors Installation and maintenance manual NOTE LEROY-SOMER reserves the right to modify the specifications of its products at any time, to take advantage of the latest technical developments. The information contained in this bulletin is therefore liable to change without notice. LEROY-SOMER gives no guarantee, whether expressed or implied, covering the information contained in this bulletin, and accepts no responsibility for any errors contained therein, nor for damage occasioned by its use. WARNING - For user safety, this controlier should be earthed. (+) - The controller is fitted with safety devices which can, in the case of certain faults, stop the controller and the motor. The motor itself can be jammed by mechanical means. Finally, voltage fluctuations, and particularly power cuts can also cause the controller to switch off. - The removal of the cause of the shutdown can lead to restarting, with consequent hazard for certain machines or installations, particularly those complying with the decrees of 15th July 1980 concerning safety. In these cases, therefore, it is important for the user to protect against such risks of restarting, by fitting a zero speed detector which will cut the supply to the controller, in the case of unprogrammed stoppages. This equipment meets existing standards. Nonetheless, it may create interference and the user accepts responsibility for carrying out the appropriate action to eliminate such interference. AS A GENERAL RULE, ANY WORK ON THE MACHINE OR INSTALLATION, WHETHER ELECTRICAL OR MECHANICAL, SHOULD ONLY BE CARRIED OUT AFTER THE POWER SUPPLY TO THE CONTROLLER HAS BEEN SWITCHED OFF.

P : Three-phase Graétz bridge. TC : Current transformer. R : Ramp. N : Speed loop. | : Current loop. L : Linearisation loop. The regulation system adopted includes multiple loops in cascade. The outside loop sets the principal controlled variable which is speed (N). The output at this speed regulation stage influences the second regulated variable, current (1). In addition, the Graétz bridge is subject to two continuous/discontinuous conduction modes in which the gain of the motor converter loop is different. This may give rise to regulation instabilities in the discontinuity zone. Regulation therefore includes a linearisation stage (L) with the characteristic | = F (V control).

Power 2 W - Check phase balance between electrenic and power sections for recommended diagram(chap. 4-2). 6.2 - STATIC SETTINGS 6.2.1 - Equipment required - A multimeter, preferably 20.000 ohms/volt. - A two-way oscilloscope, if necessary. - If required, a mobile ammeter with shunt. 6.2.2 - Supply voltage Set the three switches S1, S2 and S3 on the back of the 1210 board. They must be pushed upwards for low voltages (eg. 360 < U < 380 V) and downwards for high voltages (eg. 380 < U < 415 V). 6.2.3 - Supply voltage frequency Set all the switches on the 1214 mother board to the position corresponding to the mains power frequency 50 or 60 Hz. Set all switches (S1 to S4) to the same position. Check that : - all switches on board 1215 are set to "ON". - the resistor values of board 1215. R 101 : 220 kQ for VTU N of 38 À R 101 : 100 kQ for VTU N of 75 À R 101 : 47 kA for VTU N 2 110 А 6.2.4 - Operation with DC tachometer The + of the DT must be connected to terminal J1 - 17 The - of the DT must be connected to terminal J1 - 18 Be sure to check the polarities of the DT. To do this, turn the motor manually, in a clockwise direction when looking at the end of the shaft. (This is the direction of rotation of the motor if the polarities have been respected on armature A1 (+) ; A2 (-) and on excitation F1 (+) ; F2 (-). 6.2.5 - Operation with armature regulation (without DT) Check that terminal A1 of the armature is connected to J1-9 and that terminal A2 of the armature is connected to J1-10. In this case, there is no perfect galvanic insulation between power and control circuits but a high- impedance insulation permitting proper functioning of the VTU.N. Verify that the value of the R93 resistor on the 1215 board is indeed 270 kQ for an armature voltage of 260 V and 150 kQ for an induced 440 V. 6.2.6 - Excitation connection check ( VTU.N 38 to 110 Amperes DD DETAIL OF EXCITATION TERMINAL BLOCK cg Alternating To motor supply excitation A emmm... 170 or 190V 380V..............._... 340V y Alternating To motor supply excitation 380V...............ereecnerms 170 or 190V = N J С VTU.N 170 to 1200 Amperes D Excitation power terminal block 4-1 7 “T-T+1-1 _ F3 F3 F2| F2 | F1|FL1 FLO F2]F2]F1JFL1} FL» Excitation | Mains Excitation | Mains 190V 220V 95V 220V 340V 380V 170V 380V Full - wave Single - wave rectification rectification OY Y Y YY LUNA. 20 6.3 - DYNAMIC SETTING 6.3.1 - Setting the limitation current Factory preset value : 50 % of speed controller caliber. Disconnect the excitation power on the alternative side (FL1, FL2). There are two methods : - Method one : the VTU.N allows a current overload of 1.6 In for 10 seconds. Beyond this period, it locks to | = F(t) (CR 61). This must be carried out quickly since the motor and the commutator blades may overheat. TURN POWER ON and start operation. Display a speed index of more than 5 volts at J1-25. The speed controller will fix a current limit at 1.6 In. Using R110, set the value read on an ammeter or a shunt, to 1.6 times the motor current. TURN POWER OFF. - Method two : this gives a more accurate setting which is less burdensome to the motor. . Hook up a voltmeter between test points TP1/11 and TP1/8 on test board 1282 which is connected to the TP1 test socket on the 1215 board. - Open S5/1 and S6/1. TURN POWER ON and start operation. Display a speed index of more than 5 volts at J1-25. - Read the voltage on test point TP 1/11. This voltage, approximately 8.1 V, corresponds to the current value of the rated speed controller caliber. - Connect the voltmeter between test points TP1/10 and TP1/8 and use R110 to obtain a voltage at point TP1/10 which is equal to : UTP1/10 = UTP1/11 x rated motor current rated controller current Exemple : VTU.N 3 110 to be set for LSK 132 MO 9 | rated speed controller = 110A | rated motor = 78A After sending an increment > 5V on J1-25 a measurement is taken on UTP1/11 = 8.05 V. R110 must be set to obtain UTP1/10 = 8.05 x 78/110 = 5,7 V TURN POWER OFF and close S5/1 and S6/1 NOTE : R110 Maxi in a clockwise direction corresponds to the speed controller caliber. R110 Maxi in an anticlockwise direction corresponds to the half of the speed controller caliber. R110 has a linear course. 6.3.2 - Setting maximum motor speed with DT regulation After checking the connection polarities of the DT (see Chap. 6.2.4), reconnect be excitation power supply and select the S4 jumper position (board 1215) depending on the rated speed of the motor as shown below. S4at1:20V<UDT<60V at2:50V<UDT<130V at3:100V<UDT<300V TURN POWER ON and start operation. Set the speed index to maximum (+ 10 V), adjust the maximum motor speed with R107 by measuring the voltage read on the return DT [J1-17 (+) and J1-18 (-)].Turn R107 clockwise to increase speed. Be sure that this voltage corresponds to the motor armature voltage between A, (+) et A» (-). Do not exceed the maximum voltage specified on the motor tag. TURN POWER OFF. 6.3.3 - Setting maximum motor speed by armature control Put S4 to position 4, check that the + U is wired in J1-9 and the - U in J1-10. TURN POWER ON and start operation. Set the speed index to maximum (+10 V), adjust the maximum motor speed with R107 by measuring the armature voltage read between A1+ and A2- (this corresponds to -11V on the test point TP1/5). Charge the motor and use R114 to compensate for any fall-off in speed. 6.3.4 - Setting acceleration and deceleration ramps The S2 switch (1215 board) selects and deselects the ramp. Set to position 2 to make the ramp operational. R105 allows fine setting the deceleration ramp. R115 allows course setting the deceleration ramp. R106 allows fine setting the acceleration ramp. R116 allows course setting the acceleration ramp. Turn these potentiometers clockwise to increase ramp time which is adjustable from 0.5 to 60 seconds. 6.3.5 - Setting the speed loop gain This adjustment is done with the ramps set to the minimum. Link TP1/8 and TP1/7 with an oscilloscope lead. TURN POWER ON and start operation. Send a speed command of about 5 V and observe the DT return signal. It must reach its speed index as rapidly as possible and without undue delay. Adjust the gain by the R109 potentiometer. TURN POWER OFF. AN Correct > | A N Too much gain : turn R109 anti-clockwise Not enough gain : turn R109 clockwise > ( It may be necessary to modify the value of C6 (original value 0.47 uF). 21 6.3.6 - Setting the current loop gain In most cases, the current loop functions correctly with R112 at its central position. Use a storage oscilloscope to obtain a more accurate setting. In this case : . disconnect the excitation on the alternative side, . link TP1/6 with an oscilloscope path, . set the ramps to minimum. TURN POWER ON and start operation. Apply a speed index to J1-25. Adjust R112 to obtain a current rise of about 8 arches À y > TURN POWER OFF and reconnect excitation power. 6.3.7 - Specific applications - Setting the current limitation for applications requiring a long, strong torque on starting (eg. : Extruder). The VTU.N allows a 1.6 In control overcurrent for only 10 seconds. For such special applications, remove the safety device (time-based overload) by opening S5/1 on the 1215 board and recalibrate the controller. The table below gives speed controller selections and adjustments based on the rated motor caliber. rated Caliber of Max. | set on motor | VTU.N selected the VTU.N 10 — > 30A 38A 16 —» 46A 31 —» 55А 70A 50 —» 85A 56 —# 90A 110A 90 —» 132A 91 —» 130A 170A 140—» 204A 131 —» 230A 300A 210—» 360A 231 —» 320A 420A 370 — > 504A 321 —» 450A 600A 513—» 720A 451 —» 680А 900A 725—»1080A 681 —» 900A 1200A 1090 —»i 440A Eg. : For a motor with a rated current of 70A, select a VTU.N of 110A and set the limitation current at 1.6 x 70A = 112A. - Setting the limitation current Disconnect the excitation power on the alternative side (FL1, FL2). TURN POWER ON and start operation. Display a speed index at J1-25 of more than 5 V. The speed controller will set a limitation current at 1.6 In. With R110, adjust the value read on an ammeter or a shunt to 1.6 times the rated motor current. Respect the maximum values given in the table above. TURN POWER OFF and open S5/1 on the 1215 board. 22 ES SÓ 7.-OPTIONS 7.1 - TEST BOX Sockets for oscilloscope leads (2.5V max.)
