ACS550-02/U2 User’s Manual 137
Parameters
Group 10: START/STOP/DIR
This group:
• defines external sources (
EXT1 and EXT2) for commands that enable start, stop
and direction changes
• locks direction or enables direction control.
To select between the two external locations use the next group (parameter 1102).
Code Description
1001 EXT1 COMMANDS
Defines external control location 1 (EXT1) – the configuration of start, stop and direction commands.
0 = NOT SEL – No external start, stop and direction command source.
1 =
DI1 – Two-wire Start/Stop.
• Start/Stop is through digital input
DI1 (DI1 activated = Start; DI1 de-activated = Stop).
• Parameter 1003 defines the direction. Selecting 1003 = 3 (REQUEST) is the same as 1003 = 1 (FORWARD).
2 =
DI1,2 – Two-wire Start/Stop, Direction.
• Start/Stop is through digital input
DI1 (DI1 activated = Start; DI1 de-activated = Stop).
• Direction control [requires parameter 1003 = 3 (REQUEST)] is through digital input DI2
(
DI2 activated = Reverse; de-activated = Forward).
3 =
DI1P,2P – Three-wire Start/Stop.
• Start/Stop commands are through momentary push-buttons (the P stands for “pulse”).
• Start is through a normally open push-button connected to digital input
DI1. In order to start the drive, the digital
input
DI2 must be activated prior to the pulse in DI1.
• Connect multiple Start push-buttons in parallel.
• Stop is through a normally closed push-button connected to digital input
DI2.
• Connect multiple Stop push-buttons in series.
• Parameter 1003 defines the direction. Selecting 1003 = 3 (
REQUEST) is the same as 1003 = 1 (FORWARD).
4 =
DI1P,2P,3 – Three-wire Start/Stop, Direction.
• Start/Stop commands are through momentary push-buttons, as described for
DI1P,2P.
• Direction control [requires parameter 1003 = 3 (REQUEST)] is through digital input DI3
(
DI3 activated = Reverse; de-activated = Forward).
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”).
• Start Forward command is through a normally open push-button connected to digital input
DI1. In order to start the
drive, the digital input
DI3 must be activated prior to the pulse in DI1.
• Start Reverse command is through a normally open push-button connected to digital input
DI2. In order to start
the drive, the digital input
DI3 must be activated during the pulse in DI2.
• Connect multiple Start push-buttons in parallel.
• Stop is through a normally closed push-button connected to digital input
DI3.
• Connect multiple Stop push-buttons in series.
• Requires parameter 1003 = 3 (
REQUEST).
6 =
DI6 – Two-wire Start/Stop.
• Start/Stop is through digital input DI6 (DI6 activated = Start; DI6 de-activated = Stop).
• Parameter 1003 defines the direction. Selecting 1003 = 3 (
REQUEST) is the same as 1003 = 1 (FORWARD).
7 =
DI6,5 – Two-wire Start/Stop/Direction.
• Start/Stop is through digital input DI6 (DI6 activated = Start; DI6 de-activated = Stop).
• Direction control [requires parameter 1003 = 3 (
REQUEST)] is through digital input DI5.
(
DI5 activated = Reverse; de-activated = Forward).
8 = KEYPAD – Control Panel.
• Start/Stop and Direction commands are through the control panel when
EXT1 is active.
• Direction control requires parameter 1003 = 3 (
REQUEST).
9 = DI1F,2R – Start/Stop/Direction commands through DI1 and DI2 combinations.
• Start forward =
DI1 activated and DI2 de-activated.
• Start reverse =
DI1 de-activated and DI2 activated.
• Stop = both DI1 and DI2 activated, or both de-activated.
• Requires parameter 1003 = 3 (
REQUEST).
10 =
COMM – Assigns the fieldbus Command Word as the source for the start/stop and direction commands.
• Bits 0,1, 2 of Command Word 1 (parameter 0301) activates the start/stop and direction commands.
• See Fieldbus user’s manual for detailed instructions.
