Programming
Extended PID Speed OL or [8] Extended PID
Speed CL.
[80] PTC Card 1 All digital inputs can be set to [80] PTC Card
1. However, only 1 digital input must be set
to this option.
[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 Evacuation mode for lifts or elevators. The
Detection 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.
[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.

Resets the safety option. Available only when

Starts the homing function selected in
parameter 17-80 Homing Function. Must
remain high until homing is done, otherwise
homing is aborted.
Activates the monitoring of the touch sensor
input.
This option selects between absolute and
relative positioning. The option is valid for
the next positioning command.
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 in
parameter 17-90 Absolute Position Mode and
parameter 17-91 Relative Position Mode.
Synchronization mode: High signal locks the
actual follower position to the actual master
position. The follower starts and catches up
with the master. Low signal stops the
synchronization and the follower makes a
controlled stop.
Normally open contact for defining the
home position. The function is defined in
parameter 17-80 Homing Function. Available
only at digital inputs 18, 32, and 33.
Normally closed contact for defining the
home position. The function is defined in
parameter 17-80 Homing Function. Available
only at digital inputs 18, 32, and 33.
Normally open contact. Serves as a reference
for touch probe positioning. Available only at
digital inputs 18, 32, and 33.
