FadalMaintenance ManualWhen reverse direction is required both the reverse and motor signal have to beactivated. The turret motor reverse is activated by the Mill Interface PCBA(1040) pulls the line low on pin 5 which goes though the following connections:1060/J7-6to 1100-1/J1-6to 1100-1/J2-12to 1100-2/J1-12to Solid State Relay K11 on one side of the primary with the other sideconnected to 5 VDC. This activates the relay, closing the contacts and allowsthe 120 VAC to flow to F5 to the coil of Mechanical Relay K5 opening thenormally closed contacts and closing the normally open contacts. Resulting in1100-2 TB1-7 to 1860 J3-2 line having 120VAC for forward and 0 VAC forreverse when the motor line is active.For the Turret Motion sensor, the Hall effect switch for ATC turret connects to J6on the Servo turret control board (1860). Pin 1 is 5 VDC, pin 2 is the signal andpin 3 is Gnd. The sensor connections from the motherboard (1060) J12connect to the control board at J5, signal connecting J12-8 to J5-4, Gnd J12-7 to J5-3 and J12-9 5 VDC not connected.For an AC Brushless machine, a Power Supply (PCB-0173) is required becausethe DC motor amp chassis outputs about 130 VDC on the axis amplifier chassiscapacitor and the AC motor chassis outputs about 320 VDC. The servo turretamplifier does not operate correctly with the excess voltage. If the machinerequires a power supply, then the wiring connections are pins 1 & 2 on thepower supply. Connect to TB1-9 & TB1-8 respectively on the 1100-1 board,which is the control signal input. Pins 3 & 4 on the power supply connect to the120 RET and VAC terminals on the 1100-2 PCBA. Pin 5 on the power supplyconnects to pin 3 on J2 (black wire) of the servo turret amp PCBA (1810). Pin 6on the power supply connects to pin 4 on J2 (red wire) on servo turret amp.This is the amp's power.K33 contacts are controlled by the E-Stop circuit on the coil side of therelay. Contacts will open when E-Stop condition exists and stop operationof the turret.K3 has two sets of normally closed contacts (3,4 to 11,12) which provide apath for the 120 VAC for the drawbar and slide motor reverse circuits. Thisperforms two functions: One is the removal of power during the E-Stopcondition and the other is removal of power when the spindle is running in theforward direction.118 Section 05: Automatic Tool Changers March 2003
FadalMaintenance ManualServo TurretController andAmplifier Boards(PCB-0108)The Servo Turret Amplifier Assembly (PCB-0108) consists of a mounting plate,Controller board 1860 and a Amplifier board 1810.The Amplifier board has an input of about 130VDC and the motor output at J2.Two motor circuit fuses are AGC10A. J1 and J3 provide communicationbetween the Amplifier and the Controller boards. The Amp also has an LED toindicate over temperature and for over current.The Controller board has J1 and J4 for communication between the boards.The controller receives feedback (1860/J2) from an encoder on the motor witha 1:1 ratio to worm gear and three revolutions for one tool position change. Theencoder is a 1000 line per revolution encoder. J3 is the input connection for thecommand signal from the 1100-2 board. 5 VDC and ground are provided onpins 1 and 2 of J5 and output the Turret Motion signal to the Motherboard(1060/J12 pins 7 & 8) from pins 3 and 4. The Turret Motion Hall Effect Sensoris connected to J6. The Controller has an LED for the Turret Motion sensoractive and a pulse LED flashes indicating the board is active. S1 is a resetswitch for the board.The only adjustments on the Servo Turret board are by means of the four dipswitches.SPEED SW1 SW2 MOTOR RPMSlow 0 Closed 0 Closed 550Medslow 1 Open 0 Closed 600Medfast 0 Closed 1 Open 650*Fast 1 open 1 open 750MOTOR SW3 SW4Reserved 0 Closed 0 ClosedReserved 1 Open 0 ClosedReserved 0 Closed 1 Open*Owisso/Bodine 1 Open 1 Open*Factory SettingRandom servo amp faults may occur, often with either heavy tools and/or the30 tool ATC. Lowering the motor speed selection has been successful ateliminating these servo amp faults. However, this is not recommendedbecause of the possibility of the Z axis coming down prior to the ATC turretreaching its position.March 2003 Section 05: Automatic Tool Changers 119
