AR absolute battery install with MEXE02

Post by om_tech_support_MD » Thu Mar 28, 2019 8:02 am

To make the AR series absolute, you need to connect the battery to store the position. As an absolute system it will store the electrical home position even after power is removed. With an absolute system, you may not need a home or limit sensor. Without the battery, when you turn on the driver, your current position becomes your new electrical home position. In the case without a battery, you need to add a home sensor to find the home position in the event of power removal.

Just a few notes on connecting the battery to make installation easier. The battery needs 32 hours to fully charge (step 2 of 6). The battery can store the position for approximately 15 days when fully charged.

Step 6. Do not power cycle the driver until after you use the position preset, P-PRESET, or you will have to start all over. After hitting the absolute position error Reset, Jog to the location you want to make your home position using the JOG arrows in the teaching remote operation. Once you are at your desired home location, hit the Position PRESET button. When you select P-PRESET, it will change your current location to your electrical home position ( 0 steps).
