05/21:

External emergency stop

Defines this terminal as an emergency stop command. By
programming one of the multifunction switches as an emergency stop
the customer can override a run command and force the drive to
decelerate to a stop. Once the emergency stop signal is removed, the
run/stop command must be removed and reengaged to get the drive
to restart. The fault contact is controlled by Fn97 as follows:

Fn97= X0XX: Fault contact is not energized after external emergency stop

signal is received
X1XX: Fault contact is energized after external emergency stop
signal is received

06/22:

External baseblock

Defines this terminal as a base block command (coast to a stop). By
programming one of the multifunction switches as a baseblock contact,
the customer can override a run command and force the drive’s output
to turn off immediately allowing the motor to coast to a stop. After the
baseblock command disappears, the run/stop command must be
removed and reapplied to restart the drive. The fault contact is controlled
by Fn97 as follows:

Fn97 = 0XXX: Fault contact is not energized after external baseblock.

1XXX: Fault contact is energized after external baseblock.

07/23:

Speed search:

Refer to Fn48

Defines this terminal as a speed search command. This feature is
only available if Fn48 = X0XX. When one of the multifunction input
command signals is programmed to a speed search contact, the drive
can be remotely instructed to either start at the initial frequency
reference of Fn42 or start using the speed search feature. Energizing
the multifunction input that is programmed at the speed search contact
will allow the drive to use speed search for its start frequency. De-
energizing the multifunction input that is programmed as the speed
search contact will allow the drive to use Fn42 as its starting frequency.

08/24:

Energy saving mode:

Refer to Fn82

Defines this terminal as an energy saving mode switch. This feature
is only available if Fn82 = XX01. When the contact is energized, the
output voltage of the drive will be adjusted to minimize the amount of
energy required to maintain motor speed. With this contact de-energized
the output voltage will be a function of the V/F pattern only.

09/25:

Control signal selection

Defines this terminal as a control signal selection switch. By
programming one of the multifunction switches as a control signal
selection switch the customer can remotely select the source of the
speed reference signal as a start stop signal as described below.
When the multi-input terminal is OFF, the Operation command and/or
Frequency command is either from digital operator or remote control
(TM2) - according to the settings of Fn10/Fn11. When the multi-input
terminal is ON, the operation command and/or frequency command
is from the digital operator regardless of the settings of Fn10/Fn11.

10/26:

Communication control mode selection

Defines this terminal as a communication enable/disable switch. By
programming a multifunction input switch as a communication control
mode selection switch, the customer can select whether the unit
accepts its command signals through the communications port on
Con 12, or via the keypad on the drive. With the multi-input terminal
off during communication, the drive can receive run/stop and frequency
command signal from external communication source. The function
