Parameter Descriptions
[91] PROFIdrive The functionality is the same as the
OFF2 corresponding control word bit of the
PROFIBUS/PROFINET option.
[92] PROFIdrive The functionality is the same as the
OFF3 corresponding control word bit of the
PROFIBUS/PROFINET option.
[94] Light Load Light-load detection is a feature for lift
Detection 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 Measurement Duration,
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.
NOTICE
Flying start overrules light-load
detection.
[95] Evacuation Evacuation mode is a feature for lift
applications to enable drives to operate at
reduced DC Voltage for evacuation of people
in case of power failure. When the feature is
activated, under voltage limits and enable
voltage limits is reduced so that the drive can
be operated with 230 V single-phase UPS
supply.
[96] Mains Loss 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
frequency converter. When the signal on the
digital input is low (0), the frequency
converter forcibly turns off the kinetic back-
up.
NOTICE
Only available for pulse inputs at
terminals 32/33.
[97] Mains Loss When the signal on the digital input is high
Inverse (1), the frequency converter forcibly turns off
the kinetic back-up. For more details, see the
description of [96] Mains loss.
NOTICE
Only available for pulse inputs at
terminals 32/33.
[98] Start edge Edge-triggered start command. Keeps the
triggered start command alive. It can be used for a
start push key.
[100] Safe Option Resets the safety option. Available only when
Reset the safety option is mounted.

Sets actual master position to the value of
parameter 17-88 Master Home Position.
NOTICE
This option is available only with
software version 48.XX.
Changes the sign of the set target position.
For example, if the set target is 1000, the
activation of this option changes the value to
-1000.
NOTICE
This option is available only with
software version 48.XX.
Activates the master offset selected in
parameter 3-26 Master Offset when
parameter 17-93 Master Offset Selection has a
selection from [1] Absolute to [5] Relative
Touch Sensor.
NOTICE
This option is available only with
software version 48.XX.
Enable signal for the virtual master function.
Only applicable when option [10] Synchroni-
zation is selected in
parameter 1-00 Configuration Mode.
NOTICE
This option is available only with
software version 48.XX.
Starts the homing function selected in
parameter 17-80 Homing Function. Must
remain high until homing is done, otherwise
homing is aborted.
NOTICE
This option is available only with
software version 48.XX.
Activates the monitoring of the touch sensor
input.
NOTICE
This option is available only with
software version 48.XX.
This option selects between absolute and
relative positioning. The option is valid for
the next positioning command.
NOTICE
This option is available only with
software version 48.XX.
Positioning mode: The frequency converter
activates the selected positioning type and
target and starts the motion towards the new
target. The motion starts either immediately
or when active positioning is completed,
depending on settings of
parameter 17-90 Absolute Position Mode and
parameter 17-91 Relative Position Mode.
