Adaptive start profile (Par. 1-13):
1. Early acceleration
2. Constant acceleration
3. Late acceleration
4. Start ramp time (Par. 1-6)
NB!
AAC will control the load according to the programmed profile. Start current will vary according to the selected acceleration profile and
the programmed start time.
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. 1-12 Adaptive Control Gain as follows:
If 1-12 is at default setting of 75%, adjust to 76%.
If 1-12 is not at default setting of 75%, adjust to 75%.
5.3.4 Kickstart
Kickstart provides a short boost of extra torque at the beginning of a start, and can be used in conjunction with current ramp or constant current starting.
Kickstart can be useful to help start loads that require high breakaway torque but then accelerate easily (for example flywheel loads such as presses).

5.4 Stopping Modes
5.4.1 Coast to Stop
Coast to stop lets the motor slow at its natural rate, with no control from the soft starter. The time required to stop will depend on the type of load.
