With this utility, the following actions can be accomplished:

•Set and program the Encoder module’s parameters in EEPROM

•Activate the motors in each direction at variable speed

•View the measured encoder counts

•View the measured encoder speed

•View the status of the Limit Switches

The screen is composed of the following buttons and displays:

1- Setting of the Encoder’s threshold level

2- Setting of the Time Base for speed computation

3- Setting Divider for computing relative distance

4- Measure and display speed and relative distance

5- Measure and display counter values

6- Detect and display optional limit switch status

7- Start/Stop communication with controller

8- Set motor speed and direction for testing

Encoder Module Parameters Setting

The Encoder module has four programmable parameters: Two Time Bases (one for each encoder), a Divider for computing relative distance, and the voltage threshold for discern- ing a 0 or 1 level at the encoder’s output. In the case of the AX1500, the threshold is fixed at 2.5V and cannot be changed.
