Electrical Installation of the Encoder
A VDD encoder should be used with the VC350A control. The available cables used to connect the encoder to the
control are listed in
Section 12—Part-Number List .
To connect the encoder to the control, follow these steps:
1. Insert the encoder cable into the control enclosure through a cord grip located on the bottom panel of the
control.
2. Connect the encoder cable to the four-terminal connector labeled “J3-ENCODER” on the interface board
as shown in Figure 6-9.
Note! All other leads may be cut flush with the cable jacket.
3. Ensure that screw terminals are tight.
4. Tighten the cord grip used by the encoder cable.
Note! The wire colors in Figure 6-9 are formatted as follows:
Figure 6-8. Typical Installation of a Gear-Driven Encoder
To install a gear-driven encoder (Figure 6-8), follow these steps:
1. Install the driver gear on the line shaft.
2. Tighten the set-screws.
3. Position and install the encoder so that it is square with the drive gear.
4. Raise or lower the encoder to tighten the belt against the drive gear. (Ensure that the two sides of the belt
are not pressed together under the wheel.) Due to the low torque required, the belt should not be extremely
tight.
Note! At least 7-9 teeth should engage in the line shaft driver gear. It may be necessary to fabricate an
adjustable bracket to connect the encoder base to the parent machine frame.
