Function
Enables the extended process PID controller. Equivalent to
parameter 7-50 Process PID Extended PID. Available only if
parameter 1-00 Configuration Mode is set to [7] Extended PID
Speed OL or [8] Extended PID Speed CL.
All digital inputs can be set to [80] PTC Card 1. However, only 1
digital input must be set to this option.
The functionality is the same as the corresponding control word
bit of the PROFIBUS/PROFINET option.

Light-load detection is a feature for lift application to ensure
that the lift runs in the evacuation direction which requires
the least energy (UPS capacity), during an emergency. See
parameter 30-25 Light Load Delay [s], parameter 30-26 Delay
Before Measurements, parameter 30-27 Light Load Speed [%],
parameter 30-28 Evacuation Speed [%], and parameter 30-29
Ramp Time for light-load detection configurations.
Flying start overrules light load detection.
Evacuation Mode is a feature for lift application to enable dri-
ves to operate at reduced DC voltage for evacuation of people if
there is power failure. When the feature is activated, undervolt-
age limits and enable voltage limits are reduced so that the drive
can be operated with 230 V single-phase UPS-supply.
Select to improve kinetic back-up. When the mains voltage goes
back to a level that is close to (but still lower than) the detection
level, the output speed increases and kinetic back-up remains
active. To avoid this situation, send a status signal to the drive.
When the signal on the digital input is low (0), the drive forcibly
turns off the kinetic back-up.
Only available for pulse inputs at terminals 32/33.
