Mounting the Encoder
An encoder must be installed in order for the control to determine the speed of the parent machine. Your MCP-8
Control system can use either a wheel-driven VDD encoder and a measuring wheel or a hollow shaft encoder. For
optimal results, use a VDD-1000 encoder for one of the following resolutions: a 10 inch wheel = 100 pulses/inch; a
250mm wheel = 4 pulses/mm.
To install a wheel-driven encoder, follow these steps:
1. Mount the encoder bracket to the frame of the parent machine.
2. Mount the encoder to the bracket and securely affix the wheel.
3. Ensure that the wheel of the encoder rides securely against the belt and does not slip.
For best results, the wheel of the encoder assembly should ride on
the bottom side of the belt on the drive side.
