Back Panel Connections for the AWU4AM2
Listed below are the pinouts of the non-power connectors on the back panel of all AWUs. The functions shown are those available on the latest production units. A note of 1or 2 means that this function is new or changed with the introduction of the M2 units.

This information is provided to help users and potential users understand what remote features are achievable with the AWU. It is presented as a guide only. For standard operation a Master Panel is connected to the Master Panel Port. For simple expansion a LEX-6 is connected to the Expansion Port. Custom systems may require connections to both of these ports.

Notes
  1. This is a new signal for a new function introduced in the AWU-4AM2.
  2. The use of this signal has changed in some way with the introduction of the AWU-4AM2.
  3. The function of this pins is controlled by internal set up. See chapter 6 of the manual.
  4. Connection to this pin is required for normal operation. Consult the manual or factory for more information.
  5.  Connection to this pin required for most types of limit expansion. Consult the manual or factory for more information.
  6.  The LEX-6 connects to these pins only.
EXPANSION PORT - 25 PIN "D"
# Note Function
- Jog Run 1= AWU momentary Run ( 13 to 24 VDC)
- Secondary Stop 1= Activates an electronic stop ( 13 to 24 VDC)
3 - Reserved 
2,3 Encoder Signal This signal is buffered. It may be selected to either the "+1"0/-10 range of the encoder or to 0 to +10.0 volt range that is the same as the target 11 signal.

Units are normally shipped set to 0 to+10.0

5 6 Target 5
6 6 Target 6
7 6 Target 7
8 6 Target 8
9 6 Target 9
10 6 Target 10
11 1,3, Target 11 0.0 volts = position zero - 10.0 volts = position 1000

As shipped this pin has no effect. If enabled it can be used as an external limit input. It is then selected as Limit 10. 

12  1,3 Target 10/11 Enable When configured this line controls wheher AWU is enabled when Limit 10 is selected.

The default is that it is identical to line 23.

13  - RUNNING low = AWU is running - An open collector output
14  - EXT REF If configured this line may be used to speed master the AWU. ( 0 to +10VDC)
15  - EXT. START If configured 1 = external stop ( 13 to 24 VDC) ( semi-isolated)
16  - "IN" +15 CMOS logic level - 1= AWU will move in 0 = AWU will move out
17  - "OUT" +15 CMOS logic level - 1= AWU will move out 0 = AWU will move in
18  - +15 Power supply for external equipment. 100mA 
19  - -15 Power supply for external equipment. 100mA
20 6 POT REF+ +9.90 used for expansion pots
21 6 POT REF- -9.90 used for expansion pots
22 2,5,6 EXPANSION A This pin is used as the common supply when enabling either D25-11 or D25-23
23 2,3,5,6 EXPANSION B Normally enables Limits 5 thru 10 but if it is configured for external targets this input only enables 5 thru 9.
24 - EXT. COMMON Common for the semi- isolated control functions
25 - COMMON Common for servo electronics
Master Panel Port - 15 PIN "D"
# - FUNCTION
1 - REMOTE START CH 1 1= START ( 13 to 24 VDC)
2 - REMOTE START CH 3 "
3 - REMOTE START CH 5 "
4 - REMOTE START CH 7 "
5 3 EXT. SPEED VOLTAGE  If configured this is external speed mastering input

(default is no conection)

6 - EXT. COMMON
7 4 EXT. STOP  1= ENABLE / 0= STOP ( 13 to 24 VDC)

This is the main external electronic stop input

8 3 ,4 PS OUT (24V or 15V) Shipped default = 24VDC .
9 - REMOTE START CH2 1= START ( 13 to 24 VDC)
10 - REMOTE START CH4 "
11 - REMOTE START CH6 "
12 3 REMOTE START CH 8 or SPEED REF OUT Shipped default = START CH8 - Function depends on configuration. 
13 - REF. COMMON
14 4 EXT. COMMON
15 4 MASTER ENABLE/ EMERGENCY STOP 1= ENABLE / 0 = E-STOP ( 13 to 24 VDC)

This is the main emergency stop loop input. 


 
 
Jumper connector need to run AWU with out a master panel
# - Function
7 - EXT. STOP  Short these pins together on a male connector to make a jumper that allows testing of the AWU without a master panel. All running systems MUST have a means to activate Emergency Stop. This jumper is just to allow testing of the system where there is no possibility of misoperation causing injury. See the manual for detail on Emergency Stop means.
8 - PS OUT (24V or 15V)
15 - MASTER ENABLE/ EMERGENCY STOP

 
Motor Drive Control Port - D5F Connector
# - Function
1 4 Common Common and Shield ( shielded wire optional )
2 4 Speed Control -10 TO +10 VDC Referenced to pin 1 
3 4 Run Loop Common Common for Pins 4 and 5 
4 4 Run/stop  Contact closure - Closed = Running enabled . Closed only during motion
5 4 E-stop  Contact closure - Closed = Running enabled. Normally closed
The Machine Limit Switch Port - D3F Connector
# - Function
1 - Common Normally not used
2 4 Limit Loop Out To dry contact extreme travel switch on winch or other safety cut outs.
3 4 Limit Loop Return To dry contact extreme travel switch on winch or other safety cut outs.
Encoder Potentiometer Port - D4F connector
# - Function
1 4 Shield / common It is advisable that this cable be run in high quality shielded cable.
2 4 Location Voltage To the wiper of the encoder pot
3 4 + Ref (10.00) By convention to the CCW end of the encoder pot
4 4 - Ref (-10.00) By convention to the CW end of the encoder pot
