    Potentiometer rotation or input signal. In the Non-Linear Torque mode (NL), the torque is var- ied by the Main Speed Potentiometer or input signal, and remains constant throughout the motor’s entire speed range. In addition, Regenerate-to-Stop (RTS) or Coast-to-Stop (CTS) stop modes are also provided.

    Warning! Do not wire switches or relays in series with the armature. Armature switch- ing can cause catastrophic failure of motor and/or control. To avoid erratic operation, do not bundle AC line and motor wires with potentiometer wires, voltage following wires, Start/Stop Switch wires, enable wires, or any other signal wires.

    Note: Do not connect motor armature leads to F1 and F2 quick-connect terminals. Do not use F+ and F- terminals of Terminal Block TB2 for any purpose other than to power the field of a shunt wound motor. E. Half Voltage Field Connection (Shunt Wound Motors Only) – Wire the motor field leads to F+ terminal of Terminal Block TB2 and L1 terminal of Terminal Block TB1, as shown in Figure 6, on page 10 and as described in Table 4.

    the motor armature voltage. If the tach-generator polarity is reversed, the motor will accelerate to full speed and the Main Speed Potentiometer will not control speed. Tach- generator feedback can greatly improve speed regulation and dynamic response. Note: When using a tach-generator, the IR trimpot should be set fully counterclockwise. Note: The tach-generator input is designed for 7 Volt or 50 Volt per 1000 RPM tach-gen- erators used with 1800 RPM motors.

    Note: If Jumper J3 is set to the “T7” or “T50” position, a tach-generator must be wired to Terminal Block TB3. If a tach- generator is not used, Jumper J3 must be in either the “A180” or “A90” position. If jumper J3 is in the “T7” or “T50” position, and a tach-gener- ator is not used, the motor will accelerate to full speed and the Main Speed Potentiometer will not control speed.

    C. The hi-pot test voltage should be set in accordance to the testing agency standards and the leakage current should be set as low as possible without causing nuisance trips. D. To eliminate motor speed control damage due to auxiliary equipment hi-pot failure, it is also recommended that all signal inputs be wired together and connected to the AC input lines as shown.

  • Page 19: Viii. Trimpot Adjustments

    FIGURE 31 – OFFSET VIII. TRIMPOT ADJUSTMENTS TRIMPOT RANGE The KBRC-240D contains trimpots which are factory set for most applications. Figure 2, on page 7, illustrates the location of the trim- pots and their approximate calibrated positions. Some applications may require readjustment of the trimpots in order to tailor the control for a specific requirement.

  • Page 21: Response (Resp) Trimpot Range

    Note: If the IR compensation is too high, unstable (oscillatory) operation will result. If the control is used with a DC tach-generator, the IR trimpot should be set fully counterclock- wise. To Calibrate the IR Trimpot: 1. Run the motor at approximately 30 - 50% of rated speed at no load and measure the actual speed.
