Available only if parameter 1-00 Configuration
Mode is set to [6] Surface Winder, [7] Extended
PID Speed OL, or [8] Extended PID Speed CL.
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.

Evacuation mode for lifts or elevators. The
function magnetizes the motor before
opening the mechanical brake. The motion
starts in the direction (up or down) defined
®
by VLT Lift Controller MCO 361 using the
speed of parameter 30-27 Light Load Speed
[%]. This motion continues for the time
specified in parameter 30-25 Light Load Delay
[s] while measuring the current. If the motor
current exceeds the reference current in
parameter 30-26 Light Load Current [%], the
lift is obstructed. The direction is reversed
after the delay time specified in
parameter 30-25 Light Load Delay [s]. For the
feature to run, a start or start reverse
command is needed, together with selecting
this digital input.
NOTICE
Flying start overrules light load
detection.
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.
When the signal on the digital input is high
(1), the frequency converter forcibly turns off
the kinetic back-up. For more details, see the
description of [96] Mains loss.

Edge-triggered start command. Keeps the
start command alive. It can be used for a
start push key.
Resets the safety option. Available only when
the safety option is mounted.
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.
Starts the virtual master configured in
parameter 3-27 Virtual Master Max Ref.
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
