Ensure that there is enough clearance around the Master for cabling.
Configuring Master 810
If you are using Master 810 with an encoder that runs at a quadrature frequency higher than 300 kHz,
you must use the device's divider DIP switches to limit the incoming frequency to 300 kHz.
Master 810 supports up to a maximum incoming encoder quadrature frequency of 6.5 MHz.
The DIP switches are located on the rear of the device.
Switches 5 to 8 are reserved for future use.
This section describes how to set the DIP switches on Master 810 to do the following:
l Set the divider so that the quadrature frequency of the connected encoder is compatible with the
Master.
l Set the debounce period to accommodate faster encoders.
Setting the Divider
To set the divider, you use switches 1 to 3. To determine which divider to use, use the following formula:
Output Quadrature Frequency = Input Quadrature Frequency / Divider
In the formula, use the quadrature frequency of the encoder (for more information, see Encoder
Quadrature Frequency on the next page) and a divider from the following table so that the Output
Quadrature Frequency is no more than 300 kHz.
Divider Switch 1 Switch 2 Switch 3
1 OFF OFF OFF
2 ON OFF OFF
