Up to 250 motor learned data records are stored and accessible via the EnerVista UR Setup software through the following

The following historical data is displayed in the motor learned data records.
• Report number.
• Report date.
• Learned acceleration time (in seconds).
• Learned starting current (in multiples of full load current).
• Learned starting capacity (in percent).
• Learned average motor load (in multiples of full load current).
• Learned run time after start (in hours).
The learned values for acceleration time and effective starting current are the maximum of the individual values acquired
for the last N successful starts, where N is defined by the
The learned value for the starting thermal capacity is calculated using the maximum of the last motor start measurements
and incorporates a security margin defined by the

27% × 1.25 = 33.75%.
Learned values associated with motor acceleration require the acceleration time function to be enabled. The
learned features are not be used until at least N + 1 successful motor starts have occurred.
