The parameter uses the default overload of 60 seconds when the motor is running at 150% of the
motor rated current. When P6.01 and P6.03 are adjusted to some value other than 60 seconds or
a time until trip is needed when operating for a different time period, use the following graph and
formula to determine the trip time. The time entered into P6.01 and P6.03 is not necessarily the
trip time; refer to examples below. When the trip time has elapsed the keypad will display “EoL1/
EoL2” and the motor will coast to a stop.
P6.01 and P6.03 are EoL1/EoL2 detection time for P6.00 and P6.02.
EOL Fault Time = Operating Time from graph × P6.01/60s
Example 1: Set P6.01 = 100 seconds, and get the operation time from the graph below. Find the
time that lines up with the 50Hz curve at 150%. If the output frequency is 50Hz and the output
current is 150% of motor rated current, then the operating time is 60 seconds. Plug that time into
the formula 60s x 100s/60s = 100 seconds.

Example 2: P6.01 = 250s; output frequency = 40Hz; output current = 120%; operating time = 60s.
•
Detection Time = 125s x 250s/60s = 521 seconds�
Example 3: P6.01 = 48s; output frequency = 50Hz; output current = 132%; operating time = 60s.
•
Detection Time = 150s x 48s/60s = 120 seconds�
Example 4: P6.01 = 8s; output frequency = 20Hz; output current = 72%; operating time = 60s.
•
Detection Time = 275s x 8s/60s = 36 seconds�
