| 6. Increase the speed control signal to the maximum value allowed. 7. Locate test points TP1 and TP2 at the top of the Driver Board (Fig. 1). Attach a voltmeter (min. 1 Meg CI input impedance) across these terminals and read the DC voltage. Adjust the MAX trim potentiometer to arrive at the voltage specified in Fig. 9. 8. Locate terminals A1 and A2 on the driver board terminal block (Fig. 1). Measure the DC voltage across these terminals. Adjust the REG trim potentiometer to arrive at the voltage specified in Fig. 9. ACCELERATION AND DECELERATION ADJUSTMENT Some FPM models may not have this adjustment. Check your control's driver board. The ACCELtrim potentiometer (Fig. 1) controls the speed input responsetime, thus influencing the motor's acceleration and deceleration time. The ACCEL trim pot will have an effect when a speed signal is reduced or increased. When braking or reversing direction with the electronic F-B-R Board, the deceleration time will be determined primarily by the braking resistor value. Although the ACCEL pot will control acceleration and deceleration, deceleration is also influenced by motor speed and system inertia, which wilt vary with the application. To decrease acceleration time: turn the ACCEL trim potentiometer clockwise. The minimum acceleration time, with the pot fully clockwise, is approximately 0.5 seconds. To increase acceleration time: turn the ACCEL trim potentiometer counterclockwise.The maximum acceleration time, with the potfully counterclockwise, is approximately 10 seconds. |
