CBC1500AHFC and CBC1550AHFC
Normal Cycle:
A)
Brake is engaged.
B)
The CBC1500AHFC receives a “start input’
from external control.
C)
The CBC1500AHFC sends a “start output”
that turns on the clutch.
D)
The encoder starts rotating and display
starts counting positive numbers. If display
counts negative numbers, swap encoder
inputs Sig. A and Sig. B.
E)
The CBC1500AHFC receives an “encoder
index mark” and matches the “CBC1000
count” with the system count
(CBC1500AHFC count). The “CBC1000
count” goes back to the home reference
preset number.
F)
When the “CBC1500AHFC count” is equal
to (600 minus the braking distance), the
CBC1500AHFC sends a “stop output,”
which turns on the brake. The system will
have a soft stop. The torque of the brake
can be adjust via potentiometer on the
CBCSOO control.
G)
System arrives to a complete stop at 600
pulses.
H)
When the encoder stops turning, the
CBC1000 sends a “zero speed” output to
the microcontroller.
Fast cycle:
1)
Brake is engaged.
2)
The CBC1500AHFC receives a “start input"
from external control.
3)
The CBC1500AHFC sends a “start
output” that turns on the clutch.
4)
The encoder starts rotating and dis-
play starts counting positive num-
bers. If display counts negative num-
bers, swap encoder inputs Sig. A
and Sig. B.
5)
The CBC1500AHFC receives the
“encoder index mark” and matches
the CBC1000 count with the
CBC1500AHFC count.
6)
The CBC1500AHFC receives a sec-
ond “start input” from external con-
trol.
7)
When the CBC1500AHFC count
arrives to 600, microcontroller dis-
ables the encoder input to the
CBC1000.

8)
The CBC1000 stops counting. The display
will stop counting for a short period of time.
9)
After .05 seconds, CBC 1000 sends a “zero
speed” output to the microcontroller.
10) The microcontroller enables the encoder
input to the CBC1000.
11) The CBC1000 starts counting. AT THIS
POINT THE CBC1000 COUNT DOES NOT
MATCH THE SYSTEM’S COUNT. THE DIS-
PLAY COUNT DOES NOT MATCH THE
SYSTEM COUNT.
12) The CBC1500AHFC receives an “encoder
index mark” and matches the “CBC1000
count” with the system count
(CBC1500AHFC count). The “CBC1000
count goes back to the home reference pre-
set number. After the display changes, the
CBC1500AHFC will be capable to receive a
new “start input.” That is why the encoder
needs to be placed with the encoder mark
on the first 90 degrees of system rotation.
13) When the “CBC1500AHFC count” is equal
to (600 minus the braking distance), the
CBC1500OOAHFC sends a “stop output,”
which turns on the brake. The system will
have a soft stop. The torque of the brake
can be adjusted via potentiometer on the
CBC500 control.
14) The system arrives to a complete stop at
600 pulses.
15) When the encoder stops turning, the
CBC1000 sends a “zero speed” output to
the microcontroller.
