    3. Control Circuit and Input/Output Logic Tables Displayed below are the X2A terminal strip connections, input/output logic tables, typical run values and output conditions and functions. The table below shows the Input Status, CP25 numerical value. It is the sum of the individual input weightings. For example, Forward High Speed = 2069 = ST (1) + F (4) + I1 (16) + ID (2048).

  • Page 6: Ascl Control Startup Steps

    Escalator 4. ASCL Control Startup Steps Asynchronous Sensorless Closed Loop (ASCL) uses a control alogrithm to automatically measure and model the motor characteristics without encoder feedback. ASCL offers excellent control in both stable and dynamic motor operation, accurate speed control, and high speed stability without the additional cost and complexity of an encoder.

  • Page 7: Open Loop, V/Hz Startup Steps

    5. Open Loop, V/Hz Startup Steps Open Loop, volts per hertz (V/Hz) control does not use feedback from an encoder for operation. Instead, it relies on a volts per hertz ratio that remains constant over a set speed (frequency) range. Open Loop, V/Hz allows for quick and easy setup and does not require motor data or an encoder to operate.

  • Page 8: Closed Loop Control Startup Steps

    Escalator 6. Closed Loop Control Startup Steps Closed Loop Control uses an encoder to provide feedback for precise motor control. Speed measurements are fed back to the drive real time and constantly compared against commanded values to be adjusted accordingly. Follow the steps below for Closed Loop motor control startup. Set CP02 = 2 for Closed Loop Control.

Therefore, the ACTUAL accel/decel times must add an additional jerk time and are subject to a drive reference speed scalar.

    8. Drive Faults Faults and error codes are listed alphabetically. Additional troubleshooting of Operational Problems are listed in Section 9. The last drive fault can be found in CP36. Fault history can be viewed in the Fault Log Screen, accessible through the Menu. After 50 errors the fault log will be written down to the memory of the keypad.
