 When using emergency power (EPS), you must set the parameter to the required power
capacity for the emergency power, and then the AC motor drive calculates the acceptable
elevator speed (Pr.02-23) with the following equation.
I
= Pr.00-12 (Motor Rated Current)

NOTE:
1. When the Frequency command > fEPS, the operation speed of emergency power (EPS) is fEPS.
2. When the Frequency command ≤ fEPS, the operation speed of emergency power (EPS) is set
according to the current Frequency command.
