    2. Input Power and Motor Connection Fig.6 below shows the electrical connections for the input power and motor terminals for various EQ5 models. Verify the input power and motor terminals of the model you are installing. WITH POWER OFF, make the appropriate connections. Make sure to follow good wiring practices and all applicable codes.

  • Page 8: Check Motor Rotation And Direction

    3. Check Motor Rotation and Direction This test is to be performed solely from the EQ5 keypad. Apply power to the EQ5 drive after all the electrical connections have been made and protective covers have been re-attached. At this point, DO NOT RUN THE MOTOR, the keypad should display as shown below in Fig.

  • Page 9: Speed Reference Configuration

    4. Speed Reference Configuration The EQ5 offers users several choices to set the speed reference from different sources. The most commonly used methods are described in the next sections. Frequency reference command is selected with parameter F01. Frequency Command 1 This function selects the method by which to set the output frequency.

  • Page 13 To set the frequency reference to 60.00, a value of ‘6000’ (1770h) has to be send to the EQ5 Note: The last 2 bytes of the command strings consist of a CRC16 checksum, please refer to the EQ5 Operations Manual (Document No. TWMC-EQ5OM), chapter 8 for additional information.

  • Page 14: Run / Stop Configuration

    5. Run / Stop Configuration The EQ5 offers users several choices to run and stop the drive from different sources. The most commonly used methods are described in the next sections. Run/Stop Method is selected with parameter F02. Operation Method This function sets the operation command input method.

    6. Digital Operator Panel The Digital Operator has various functions for inputting, controlling, and displaying operations such as frequency setting, run/stop command, confirming and changing function data, confirming status, and copying. Please review and become familiar with each function before attempting to operate the drive. The Digital Operator can be removed or inserted during inverter operation, however, if it is removed during a keypad operation (e.g., run/stop, frequency setting), the inverter will stop and initiate an alarm.

    7. Motor and Application Specific Settings It is essential that before running the motor, the motor nameplate data matches the motor data in the EQ5. 7.1 Set Motor Name Plate Data (P02, P03, F11) Motor 1 (Capacity) The nominal motor capacity is set at the factory. Please verify that the motor name plate data matches the motor capacity shown in parameter P1.
  • Page 22 Acceleration and Deceleration Time (F07 / F08) Acceleration and Deceleration times directly control the system dynamic response. In general, the longer the acceleration and deceleration time, the slower the system response, and the shorter time, the faster the response. An excessive amount of time can result in sluggish system performance while too short of a time may result in system instability.
  • Page 23 Torque Boost (F09, Default 0.1) IMPORTANT: THIS PARAMETER REQUIRES TO BE CHANGED FOR CONSTANT TORQUE APPLICATIONS. This parameter sets the relationship between output frequency and output voltage. Constant torque applications have the same torque requirements at low speed as well as at high speed. Initial Setup For medium duty applications set parameter F09 to an initial value of 1.0.
  • Page 24 Medium Duty Applications Rated voltage 1 100% #1.9 Base frequency 1 #1.0 Output frequency EQ5 30HP or Less EQ5 40HP and above Heavy Duty Applications Rated voltage 1 100% #20.0 Base frequency 1 #2.0 Output frequency EQ5 30HP or Less EQ5 40HP and above Warning: A larger than required torque boost value creates over- excitation at low speeds, continued operation may cause the motor to...
