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.
3
Minarik Corporation’s model 200-0386A 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 (200-0386A) 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).

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 200-0386A 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.
Installation
Wiring
Screw terminal block
Connections to Minarik’s 200-0386A 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.

Figure 2. Screw Terminal Block
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 200-0386A does not include this pot.
Installation
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.

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.
9
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.

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
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.
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.
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.
Figure 6. Pushbutton Operation: FWD/STOP/REV Figure 7. Pushbutton Operation: RUN/STOP
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.
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.
Figure 8. Pushbutton Operation: jog Forward/jog Reverse
Figure 9. Pushbutton Operation: jog RUN
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.
Modes of Operation
Limit switch operation: FORWARD/STOP/REVERSE,
1 Cycle
17
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.
Figure 10. Limit switch operation: no automatic reversing
Figure 11. Limit Switch Operation: FWD/STOP/REV, 1 cycle
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.
Modes of Operation 19
Figure 12. Limit Switch Operation: automatic cycling
20 Modes of Operation
Foot pedal operation: FORWARD/STOP/REVERSE
In this mode the motor runs as long as a pedal is depressed.
When the pedal is released the drive will regeneratively brake the motor. When reversing the direction of travel it is necessary to release one pedal before depressing the other.
Modes of Operation 21
Foot pedal operation: RUN/STOP
In this mode the motor runs as long as the pedal is depressed. Release the pedal and 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.
