Electronic Handwheel (Optional)
The electronic handwheel (pulse follower) is an optional connection that allows
the control to follow the pulses from an encoder input. This is a factory installed
option and must be ordered with the control. This wiring must be separated
from power wiring. Separate encoder cable by at least 3
″
from parallel runs of
power wires. Cross power wires at right angles only.
Cable Preparation
Encoder wiring must be shielded twisted pairs, #22 AWG (0.34mm
2
) minimum
size, 200
′
(61m) maximum, with an insulated overall shield.
DBSC Control End (See Figure 3-10.)
1.
Strip the outside jacket approximately 0.375
″
(9.5mm) from the end.
2.
Solder a #22 AWG (0.34mm
2
) wire to the braided shield. Carol cable has
a clear Mylar sleeve between the braided shield and the wire bundle.
Belden cable does not have a Mylar sleeve.
3.
Connect all shields to X9-13. To do this, solder a “Drain Wire” from each
shield to the wire soldered to the braided shield in step 2.
4.
Insulate or tape off ungrounded end of shields to prevent contact with other
conductors or ground.
Encoder End
1.
Strip the outside jacket approximately 0.375
″
(9.5mm) from the end.
2.
Identify each of the four twisted pair and label or use the color codes
shown in Figure 3-10.
3.
Insulate or tape off ungrounded end of shields and unused conductors to
prevent contact with other conductors or ground.
CAUTION: Do not connect any shields to the encoder case or motor
frame. Do not connect any shields to ground or another
power supply or damage to the control may result.
