Parameter Description
Determines how the emergency power function is activated. The emergency
power function allows the drive to run off of a UPS or battery back up
system, 460V units can be run from a 230V 1 phase supply. 230V units
can be run from a 230V 1 phase supply.
When active the under voltage fault level is reduced to 160VAC. The input
phase failure detection is shut off, and the torque limit is reduced to the
rated torque of the motor.
If a speed is programmed for this function, then whenever the speed is
selected, the drive automatically goes into emergency operation. If the
function is triggered by a digital input (X2A.10), the input must be active
when the drive is enable and must remain active for at least one second.
Settings: Off = no function
SPd1 = Intermediate speed one serves as the emergency
operation speed.
SPd2 = Intermediate speed two serves as the emergency
operation speed.
SPd3 = Intermediate speed three serves as the emergency
operation speed.
di 1 = Digital input X2A.10 activates the emergency operation
(this mode is not possible if LF.57 =2).
Note: If a 460V unit is being powered from a 230V UPS system, the
maximum car speed can be 50% of contract speed. Higher speeds
will result in loss of control due to low DC bus voltage.
A setting of SPd1, SPd2 or SPd3 can not be used if the one oor
positioning function (LP.1 = P onE) of the drive is activated.

This parameter is used to control the HSd output.
0% = standard HSd output operation
Value > 0% = HSd output acts as the ETS output
When the actual speed reaches the percentage of the contract speed set
in this parameter, the ETS output will turn on. When the actual speed falls
below this value, the ETS output turns off.
Unit: %
Value range: 0% … 100 %
Default setting: 0 %
Adjusted value: dependent on use
