The power and control connections, and the parameter settings for each example are shown. Details of the parameters are in the Drive Setup section. It may helpful to find the example closest to the requirements of your installation and use it as a guide.
  • Page 38 ® Series 3500 Example 2: In a ventilating system, the ability to reverse the fan in the case of fire is required. The control signal used is 4 to 20 mA, corresponding to 10 to 100% motor speed, typically 6 to 60 Hz. A remote indication of motor speed is required.
  • Page 39 ® Series 3500 Example 3: A fan is to be controlled manually by means of a 0 to 10 V DC potentiometer corresponding to 10 to 60 Hz. A thermistor is installed in the motor to obtain optimum motor protection. The thermistor is to be connected to the drive to shut down the drive in case of motor overtemperature.
  • Page 40 ® Series 3500 Example 4: Although three-wire “Start/Stop” is not commonly used for unattended operation, some installations may require it for operator safety. A pump is to be controlled by means of a 0 to 10 V control signal, corresponding to 18 to 60 Hz. "Start/Stop"...
  • Page 41 ® Series 3500 Example 5: The output frequency of the drive is to be controlled by means of digital signals from a PLC or floating point control. Whenever the output frequency is outside the 10 to 45 Hz range, the relay output is to be activated giving a signal to the PLC.
