    Motor FLC Par. 1-1 should be set to the motor's rated FLC. Do not add the overload rating as this is computed by the MCD-500. 5.2 AAC Adaptive Acceleration Control AAC Adaptive Acceleration Control is a new form of motor control based on the motor's own performance characteristics. With AAC, the user selects the starting or stopping profile that best matches the load type and the starter automatically controls the motor to match the profile.

  • Page 34: Current Ramp

    Set a start Current Limit (Par. 1-4) sufficiently high to allow a successful start. The first AAC start will be a Constant Current start. This allows the MCD 500 to learn the characteristics of the connected motor. This motor data is used by the MCD 500 during subsequent AAC Adaptive Acceleration Control starts. MG.17.K2.02 - VLT ® is a registered Danfoss trademark...

  • Page 35: Kickstart

    AAC cannot start the motor faster than a direct on-line (DOL) start. If replacing a motor connected to an MCD-500 programmed for AAC starting or stopping, or if the starter has been tested on a different motor prior to actual installation, the starter will need to learn the characteristics of the new motor. To force the MCD-500 into learn mode, adjust par.

  • Page 38: Inside Delta Operation

    When connected in inside delta, current imbalance is the only phase loss protection that is active during run. Do not disable current imbalance protection during inside delta operation.
