3 Safety Warnings SHOCK HAZARD AVOID HEAT KEE DR OID ATION Have a qualified electrical maintenance technician install, adjust, and service this equipment. Follow the National Electrical Code and all other applicable electrical and safety codes, including the provisions of the Occupational Safety and Health Act (OSHA) when installing equipment. Reduce the chance of an electrical fire, shock, or explosion by proper grounding, over current protection, thermal protection, and enclosure. Follow sound maintenance procedures. It is possible for a drive to run at full speed as a result of a component failure. Install a master switch in the AC line for stopping the drive in an emergency. When the switching logic board is connected to a variable speed regenerative drive it is isolated from earth ground. Circuit potentials are at 115 VAC or 230 VAC above earth ground. Avoid direct contact with the printed circuit board or with circuit elements to prevent the risk of serious injury or fatality. Use a non-metallic screwdriver for any necessary adjustments.

9 3 General Information Caution Regenerative braking imposes very high stress on the rotating components of the drive train. It is very important that these deceleration forces be considered before selecting a drive system that applies regenerative braking to a gearmotor or other gearbox. Minarik Corporation s model A provides the logic interface between the regenerative drive and pushbutton stations, foot switches, or programmable controls. It accepts dry contact mechanical closures, current-sinking open collectors, and TTL logic devices. The limit switch logic board has four operating modes, which can be configured nine different ways. Select the one that fits your application and follow the wiring and DIP switch instructions for that configuration. The speed adjust potentiometer (10K ohms, 2 watts) is wired through the logic board ( A) module, rather than directly to the regenerative drive. Use either one potentiometer for both forward and reverse speeds (Figure 4, page 7) or if different speeds are required in each direction one potentiometer for forward and one potentiometer for reverse speed settings (Figure 5, page 8).

10 4 Installation Mounting the Logic Board Logic board components are sensitive to electrostatic fields. Avoid contact with the circuit board directly. Protect the logic board from dirt, moisture, and accidental contact. Provide sufficient room for access to the terminal block. Mount the logic board away from other heat sources. Operate within the specified ambient operating temperature range. The operating temperature range for the A is 10 C through 40 C. Prevent loose connections by avoiding excessive vibration of the logic board. Mount the logic board in either a horizontal or vertical plane using the four 0.19 inch [5 mm] mounting holes located on the board.

11 Installation 5 Wiring Screw terminal block Connections to Minarik s A logic board are made to a screw terminal block. There are two screw terminal blocks on the board. The large one is shown in Figure 2. The smaller screw terminal block has a similar connection style to the one shown. Using a screwdriver, turn the terminal block screw counterclockwise to open the wire clamp. Insert stripped wire into the wire clamp. Turn the terminal block screw clockwise to clamp the wire. TERMINAL BLOCK SCREW WIRE CLAMP Figure 2. Screw Terminal Block

12 6 Installation Speed adjust potentiometer Warning Be sure that the potentiometer tabs do not make contact with the potentiometer enclosure. Grounding the input will cause damage to the regenerative drive. Install the circular insulating disk between the panel and the 10K ohm speed adjust pot. Mount the speed adjust pot through a 0.38 inch (10mm) hole with the hardware provided (Figure 3). Twist the speed adjust pot wire to avoid picking up unwanted electrical noise. If potentiometer leads are longer than 18 inch (457mm), use shielded cable. Logic lines of this length act as an antenna and can pick up noise from the drive components, noise from other devices or other ground wires, or voltage from power lines that can cause erratic operation. The A does not include this pot. MOUNT THROUGH A 0.38 IN. (10 MM) HOLE CW WIPER W NUT STAR WASHER SPEED ADJUST POTENTIOMETER PANEL INSULATING DISK Figure 3. Speed Adjust Potentiometer

13 Installation 7 It may be necessary to earth ground the shielded cable. If noise is produced by devices other that the drive, ground the shield at the drive end. If noise is generated by a device on the drive, ground the shield at the end away from the drive. Do not ground both ends of the shield. The following diagrams show the potentiometer connections to terminal block 2 (TB2). Use Figure 4 when a single speed is desired in both the forward and reverse directions. Use Figure 5 when one speed is desired in the forward direction, and a different speed is desired in the reverse direction CW 10K OHM SPEED ADJUST POTENTIOMETER Figure 4. Single Speed Potentiometer Connections

15 Installation 9 Shielding Guidelines Warning Under no circumstances should power and logic leads be bundled together. Induced voltage can cause unpredicatble behavior in any electronic device, including motor controls. As a general rule, Minarik recommends shielding of all conductors. If it is not practical to shield power conductors, Minarik recommends shielding all logic-level leads. If shielding logic leads is not practical, the user should twist all logic leads with themselves to minimize induced noise. It may be necessary to earth ground the shielded cable. If noise is produced by devices other than the drive, ground the shielf at the drive end. If noise is generated by a device on the drive, ground the sheild at the end away from the drive. Do not ground both ends of the shield. If the drive continues to pick up noise after grounding the shield, it may be necessary to add AC line filtering devices, or to mount the drive in a less noisy environment.

16 10 Modes of Operation The limit switch logic board has four (4) different modes of operation which can be configured into nine (9) difference connections. They are as follows: 1) FORWARD/STOP/REVERSE Pushbutton Operation Limit Switch Operation Foot Pedal Operation 2) RUN/STOP Pushbutton Operation Foot Pedal Operation Limit Switch Operation (no automatic reversing) 3) jog FORWARD/jog REVERSE Pushbutton Operation 4) jog RUN Pushbutton Operation Limit Switch Operation

17 Modes of Operation 11 Pushbutton switches Pushbutton switches are momentary operated type. RUN, FWD, and REV switches are normally open. STOP switches are normally closed. Limit switches Limit switches are single pole, single throw, normally closed. Foot pedals Foot pedals are single pole, single throw, normally open. DIP switches Use a small screwdriver to change DIP switch settings. The arrow on the dip switch box indicates the ON position.

18 12 Modes of Operation Pushbutton operation: FORWARD/STOP/REVERSE In this mode the appropriate pushbutton initiates travel. The motor is reversed by pressing the opposite direction pushbutton. The stop pushbutton will regeneratively brake the motor. OFF OFF O N TB501 FWD REV STOP JUMPER Figure 6. Pushbutton Operation: FWD/STOP/REV

19 Modes of Operation 13 Pushbutton operation: RUN/STOP In this mode the RUN pushbutton is actuated to start the motor. The motor will continue to run until the STOP pushbutton is depressed. This mode does not allow reversing. If the motor runs in the wrong direction, shut down the system and reverse the armature connections to the regenerative drive. OFF OFF O N TB501 RUN STOP JUMPER Figure 7. Pushbutton Operation: RUN/STOP

20 14 Modes of Operation Pushbutton operation: jog FORWARD/jog REVERSE In this mode the motor turns only when the forward or reverse pushbutton is being depressed. To reverse the motor, first release the activated pushbutton to regeneratively brake the motor. Then push the opposite direction pushbutton. ON ON O N TB501 FWD REV JUMPER JUMPER Figure 8. Pushbutton Operation: jog Forward/jog Reverse

21 Modes of Operation 15 Pushbutton operation: jog RUN In this mode the motor turns only as long as the RUN pushbutton is depressed. When the pushbutton is released the drive will regeneratively brake the motor. If the motor runs in the wrong direction, shut down the system and reverse the armature connections to the regenerative drive. ON ON O N TB501 RUN JUMPER JUMPER Figure 9. Pushbutton Operation: jog RUN

22 16 Modes of Operation Limit switch operation: no automatic reversing In this mode activating the appropriate pushbutton will initiate travel. The motor will regeneratively brake when the corresponding limit switch is actuated (opened) or when the STOP pushbutton is depressed. If travel is interrupted by STOP before the limit switch is reached, it can be resumed by pressing the appropriate direction pushbutton. OFF OFF O N TB501 REV FWD REV STOP FWD Figure 10. Limit switch operation: no automatic reversing

23 Modes of Operation 17 Limit switch operation: FORWARD/STOP/REVERSE, 1 Cycle In this single-cycle mode the motor automatically returns to the REV limit switch location. It normally begins at that site with the actuation of the FWD pushbutton. If the starting position is not at the FWD limit switch, press FWD to complete the balance of the automatic FWD/STOP/REV cycle or press REV to complete the REV portion of the cycle. ON OFF O N TB501 REV FWD REV STOP FWD Figure 11. Limit Switch Operation: FWD/STOP/REV, 1 cycle

24 18 Modes of Operation Limit switch operation: automatic cycling In this mode the motor will continuously cycle the load between the FWD and REV limit switches. To stop the cycling process, press the STOP pushbutton. Re-starting the cycle is dependent upon the position of the machine when stopped: If stopping occurs with the FWD limit switch activated, the REV pushbutton must be pressed to re-start. If stopping occurs with the REV limit switch activated, the FWD pushbutton must be pressed to re-start the cycle. If stopping occurs between the FWD and REV limit switches, either pushbutton may be pressed to re-start the cycle.
