Group 10: Command Inputs
Start, Stop and Direction commands can be given from the control panel or from two external
locations (
EXT1, EXT2). The selection between the two external locations is made with parameter
1102
EXT1/EXT2 SEL. For more information on control locations refer to “Appendix A” on page 151.
Code Description
1001 EXT1 COMMANDS
Defines the connections and the source of Start/Stop/Direction commands for External control location 1
(
EXT1).
0
= NOT SEL
No Start/Stop/Direction command source for EXT1 is selected.
1 = DI1
Two-wire Start/Stop connected to digital input DI1. DI1 deactivated = Stop;
DI1 activated = Start. *
2 = DI1,2
Two-wire Start/Stop, Direction. Start/Stop is connected to digital input DI1 as above. Direction is connected
to digital input DI2. DI2 deactivated = Forward; DI2 activated = Reverse. To control direction, the value of
parameter 1003
DIRECTION should be REQUEST.
3 = DI1P,2P
Three-wire Start/Stop. Start/Stop commands are given by means of momentary push-buttons (the P stands
for “pulse”). The Start push-button is normally open, and connected to digital input DI1. The Stop push-
button is normally closed, and connected to digital input DI2. Multiple Start push-buttons are connected in
parallel; multiple Stop push-buttons are connected in series. *,**
4 = DI1P,2P,3
Three-wire Start/Stop, Direction. Start/Stop connected as with DI1P,2P. Direction is connected to digital
input DI3. DI3 deactivated = Forward; DI3 activated = Reverse. To control Direction, the value of parameter
1003 D
IRECTION should be REQUEST. **
5 = DI1P,2P,3P
Start Forward, Start Reverse, and Stop. Start and Direction commands are given simultaneously with two
separate momentary push-buttons (the P stands for “pulse”). The Stop push-button is normally closed, and
connected to digital input DI3. The Start Forward and Start Reverse push-buttons are normally open, and
connected to digital inputs DI1 and DI2 respectively. Multiple Start push-buttons are connected in parallel,
and multiple Stop push-buttons are connected in series. To control direction, value of parameter 1003
DIRECTION should be REQUEST. **
6 = DI5
Two-wire Start/Stop, connected to digital input DI5. DI5 deactivated = Stop and DI5 activated = Start. *
7 = DI5,4
Two-wire Start/Stop/Direction. Start/Stop is connected to digital input DI5. Direction is connected to digital
input DI4. DI4 deactivated = Forward and DI4 activated = Reverse. To control direction, the value of
parameter 1003
DIRECTION should be REQUEST.
8 =
KEYPAD
The Start/Stop and Direction commands are given from the control panel when External control location 1
is active. To control direction, the value of parameter 1003
DIRECTION should be REQUEST.
9 =
DI1F,2R
Start forward command is given when DI1= activated and DI2= deactivated. Start reverse command is
given if DI1 is deactivated and DI2 is activated. In other cases Stop command is given.
10 =
COMM
The Start/Stop and Direction commands are given through serial communication.
*Note! In cases 1, 3, 6 direction is set with parameter 1003
DIRECTION. Selecting value 3 (REQUEST) fixes
the direction to Forward.
**Note! The stop signal must be activated before a Start command can be given.
