  • Page 13: Wiring

    DLC Series Wiring Do not install, rewire, or remove this control with input power  applied. Failure to heed this warning may result in fire, explosion, or serious injury. WARNING! Circuit potentials are at 115 or 230 VAC above ground. To prevent the risk of injury or fatality, avoid direct contact with the printed circuit board or with circuit elements.

  • Page 14: Shielding Guidelines

    WARNING! As a general rule, Minarik Drives recommends shielding of all conductors. If it is not practical to shield power conductors, it is recommended to shield all logic-level leads. If shielding of all logic-level leads is not practical, the user should twist all logic leads with themselves to minimize induced noise.

  • Page 15: Connections

    If using a regenerative drive, connect the DLC600 S1 to drive S0 and the DLC600 S2 to drive S2. Refer to Figure 6 on page 11. If using a XP-AC series drive, connect the DLC600 S1 to drive S2 and the DLC600 S2 to drive S1. Refer to Figure 6 on page 11.

  • Page 16: Feedback Terminals (+, In, C)

    Refer to Figure 6 on page 11. Frequency Terminal (Fin) The DLC600 can be used as a signal source to control another DLC600 via SO502 terminals FO+ and FO-. SO502 is a two-terminal, cage-clamp terminal block onthe printed circuit board. The frequency output available from these terminals is equal to 50% fo the commanded speed.

    DLC Series Feedback Device Selection (SW502, DIP Switches 2 & 3) DIP switches 2 and 3 are for feedback device selection (Figure 9). If using an optical pickup, hall sensor, proximity switch, or an open-collector transducer, set DIP switch 2 to ON and 3 to OFF. If a magnetic pickup is used, set DIP switch 2 to OFF and 3 to ON.

If an internal reference signal is used (normal operation), set DIP switch 4 to OFF and 5 to ON. If an external reference signal is used, set DIP switch 4 to ON and 5 to OFF.

  • Page 23: Section 6. Calibration

    Use a non-metallic screwdriver for calibration. Each trim pot is identified on the printed circuit board. Calibrate the drive for use with the DLC600. The purpose is to optimize the response on the drive to the DLC600 signal and to minimize any tendency by the drive to independently attempt to regulate motor speed.

  • Page 24: Min And Max

    3. Adjust the MIN trim pot CW until the motor shaft starts to rotate. Slowly adjust the MIN trim pot CCW until the motor just stops. 4. Set the DLC600 speed to 200% of maximum desired motor speed as outlined in step 2 above.

    Decimal Point Location The decimal point location number fixes the decimal point within the DLC600 display. The DLC600 may be set for no decimal point, or for a decimal point in the tenths, hundredths, or thousandths position. The factory setting is for no decimal point.

  • Page 28: Entering The Programming Mode

    Entering the Programming Mode 1. Press and hold the ENTER pushbutton (labeled E) while applying AC power to the DLC600 only. Do not apply power to the drive. 2. Release the ENTER pushbutton after AC power is applied. You have entered the programming mode when the decimal point appears on the display in the lower right-hand corner.

    DLC Series Entering the Calculated Program Parameters 1. Press ENTER until the decimal point is displayed in the lower right corner (e.g. 1 2 3 4.). 2. Press the UP and DOWN pushbuttons until you reach the desired speed scaling factor. 3.

  • Page 30: Set The Speed

    9. Press ENTER once to return to the operating mode. 10. Remove power to the DLC600. 11. Reconnect the drive and apply power to the DLC600 and drive simultaneously. 12. The motor will accelerate to the set speed. 13. To change the set speed, repeat steps 1 - 9.

  • Page 31: Programming Examples

    DLC Series Programming Examples Example 1 An application uses a 30 tooth magnetic pickup mounted on a motor shaft. The application requires that the motor speed and display be equal to the speed entry. Calculate the program parameters. Solution: PPR = 30 (given in example) Shaft RPM = 100 (arbitrarily chosen) Speed Entry = 100 (same as Shaft RPM) Speed Display = 100 (same as Shaft RPM)
  • Page 32 DLC Series Example 2 An application uses a 60 tooth magnetic pickup mounted on a motor shaft. The application requires that the motor speed and display be equal to the speed entry. Calculate the program parameters. Solution: PPR = 60 (given in example) Shaft RPM = 100 (arbitrarily chosen) Speed Entry = 100 (same as Shaft RPM) Speed Display = 100 (same as Shaft RPM)
  • Page 33 DLC Series Example 3 An application uses a 30 tooth magnetic pickup mounted on a motor shaft that is part of an exercise treadmill. The pulley is driving a belt that has a radius of 4 inches. The applications requires the user to enter the speed in miles per hour, and the display to read in miles per hour.
  • Page 34 Adding a decimal point widens the input range (the range of settings from 0 to maximum), increases the gate time, and decreases the rounding error to the nearest digit in the first calculation of the SSF and DSF. The DLC600 has a gate time range of 0.5 - 3 seconds.
  • Page 35 Gate Time = = 0.05 seconds The gate time is not within the DLC600’s range of 0.5 - 3 seconds. There is alos a significant error (20%) in rounding 2.5 to 3. Introduce a decimal point and recalculate the program parameters. Since the user will enter 10.0 for 10 RPM, the speed entry is now 100.
  • Page 36 DLC Series Recalculating the program parameters: (Speed Entry)(3000) (100)(3000) SSF = = 25 (Shaft RPM)(PPR) (400)(30) (Speed Display)(3000) (100)(3000) DSF = = 25 (Shaft RPM)(PPR) (400)(30) Gate Time = = 0.5 seconds This is much more acceptable. Note that there is no error due to rounding here because the SSF and DSF came out to be whole numbers.

  • Page 37: Section 8. Leader-Follower Applications

    The product of the external frequency and the set speed on the DLC600 must not exceed 500 kHz. This will limit the speed set value to to 5000 or less (500,000 / 10 = 50,000; however, the DLC600 only uses 4 digits. Thus, the maximum is 5000).

  • Page 38: Leader-Follower Example Using A Leader Encoder

    DLC Series Leader-Follower Example Using A Leader Encoder In this example, the DLC600 recieves a signal from an encoder on a lead motor. The DLC600 then controls a follower motor at 100% of the lead motor’s speed. Assume the following conditions exist: - The lead motor’s maximum speed is 1800 RPM.
  • Page 39 DLC Series Step 3. Calculate the SSF Program the speed scale factor (SSF) per the following formula: FR * Set Speed SSF = where, FR calculated in step 1. FM calculated in step 2. Desired leader/follower speed ratio, expressed as a Set Speed percentage.

  • Page 41: Leader-Follower Example Using Two Dlc600'S

    Leader-Follower Connections Use 14 - 28 AWG wire to connect the leader and follower DLC600’s. Connect SO502 terminal FO- on the leader DLC600 to the C terminal on the follower DLC600. Connect SO502 terminal FO+ on the leader DLC600 to the Fin terminal on the follower DLC600.
  • Page 42 DLC Series Programming the Follower Program the follower DLC600 as follows; 1. Calculate the follower reference frequency (FR) using the following formula: 25 * Lead Motor Speed in RPM FR = SSF of Lead DLC600 In this example, assume the lead motor speed is 1800 RPM. The leader SSF in this example is 100.
  • Page 43 The speed scale factor is 50. Enter this value as the SSF on the follower DLC600. 4. It is recommended that you set the DSF of the follower DLC600 to 100. Although any you can set whatever DSF value you’d like, setting it to 100 removes the need to correlate the DSF value with system speed.
