Revolution Rotary Fourth Axis Connector

Revolution machines prior to approximately 1999, when wired for a rotary fourth axis, were generally supplied with a 28-16 MS connector.

This was a different connector type and pin-out from the 28-11 connectors used in Centroid factory-wired cabinets.

Revolution connector wiring was typically as follows:

28-16 MS Connector

Pin Signal

A Encoder ch. A to DE9 pin 8

B Encoder ch. /A to DE9 pin 5

C Encoder ch. B to DE9 pin 7

D Encoder ch. /B to DE9 pin 4

E Encoder shield to DE9 shell

F Encoder Vcc (+5VDC) to DE9 pin 9

G Encoder COM (0VDC) to DE9 pin 2

H Encoder ch. Z to DE9 pin 6

J Encoder ch. /Z to DE9 pin 3

K Motor Power + to servo drive

L Motor Power - to servo drive

M Motor Ground to chassis ground

N Clamping Pressure Switch NO (clamped) to PLC input

P Clamping Pressure Switch NC (unclamped) unused

Q Pressure Switch Common to input common

R Home Switch NO unused

S Home Switch NC to PLC input

T Home Switch Common to input common

U Clamp Solenoid from PLC output

V Clamp Solenoid from power supply

Pin	Signal
A	Encoder ch. A	to DE9 pin 8
B	Encoder ch. /A	to DE9 pin 5
C	Encoder ch. B	to DE9 pin 7
D	Encoder ch. /B	to DE9 pin 4
E	Encoder shield	to DE9 shell
F	Encoder Vcc (+5VDC)	to DE9 pin 9
G	Encoder COM (0VDC)	to DE9 pin 2
H	Encoder ch. Z	to DE9 pin 6
J	Encoder ch. /Z	to DE9 pin 3
K	Motor Power +	to servo drive
L	Motor Power -	to servo drive
M	Motor Ground	to chassis ground
N	Clamping Pressure Switch NO (clamped)	to PLC input
P	Clamping Pressure Switch NC (unclamped)	unused
Q	Pressure Switch Common	to input common
R	Home Switch NO	unused
S	Home Switch NC	to PLC input
T	Home Switch Common	to input common
U	Clamp Solenoid	from PLC output
V	Clamp Solenoid	from power supply

The clamp solenoid was typically wired for 120VAC, but this should be checked.
