GE DS200STCAG1A Gas turbine AI module

ZERO REF potentiometer Adjust this potentiometer to cancel any offset in the external speed reference signal. MAX SPEED potentiometer Turn the potentiometer anti-clockwise to reduce the maximum motor speed to 50%. Turn the potentiometer clockwise to increase the maximum motor speed to 120%.DERIVATIVE potentiometer Turn the potentiometer clockwise to reduce the amount of overshoot in the system response by increasing the derivative gain of the PID amplifier. RAMP potentiometer Adjust the potentiometer to increase or decrease the time the motor reaches maximum speed from 0 second to 2 seconds PROPORTIONAL potentiometer Turn the potentiometer clockwise to increase the proportional gain of the PID amplifier

ZERO REF potentiometer 

1. Connect the non-inverting input of the speed reference signal to pin 9 and the inverting input to pin 10.

2. Set the speed reference signal for zero speed. 

3. Remove the connection from pin 15 (STOP signal). 

4. Connect a digital multimeter to pins 11 and 12. 

5. Enable the drive and adjust the ZERO REF potentiometer to reduce the multimeter reading to not more than 1mV. 

6. Restore the original wiring. If the motor is creeping with a zero speed reference, or when a stop command is applied, please contact the supplier of the drive.

If the calculated value of RT is zero

fit a link instead of a resistor. If the calculated value is negative, the tachogenerator must be changed for one with a greater value of Ketacho in order for the motor to reach the required speed . Calculate: RT = 200 [(3 x 7) - 5] = 3.2kΩ The value of the RT resistor may be between 2.7kΩ and 3.9kW. 2. Fit the resistor. 3. Apply speed reference signal of 2V to 10V to pins 4. 9 and 10. (To generate this signal, use the external controller or the reference voltage output on pins 6 and 7.)Measure the tachogenerator output voltage with a digital multimeter and adjust the maximum speed for the multimeter to show the calculated value. Calibration should be optimized using a speed indicator.
