Refer to US04 Control Type = Binary Speed Selection & Digital Speed
Selection for description of the basic operation.
The LI03 setting only changes the logic table according to the corresponding
US04 Control Type setting.
LI04 Input 1 Function
Used to limit the maximum speed of the lift in the event the emergency power generator
is not able to provide enough power to the elevator. Maximum speed is directly
proportional to maximum power draw on the AC line.
Input 1 corresponds to digital control terminal I1, X2A1.
If this input is available, then it is free to be programmed with the one of the following
input functions:

Functions for LI04 - LI11:
Description of Functionality:
No function is assigned to input
The undervoltage limit is reduced and single phase
detection is turned off to allow for supply from 230V UPS
battery power source; the LS10 Battery Operation Speed
is selected. Additionally, carrier frequency is dropped to
2kHz to reduce switching losses at very low output
frequencies.
The torque limit is set according to the LC31 Reduced
Maximum Torque.
