Page 3: Introduction, Features And Applications
AC servo systems in velocity, precision, noise, stability and some other aspects, at least as good as those of digital AC servo systems. Synchronously the price of DB810 stays at the price line of step driver, namely far lower than that of AC servo. -

3. Connections 3.3 Typical Connections 3.1 Connector Configuration If the encoder drains less than 50mA, DB810 can supply the encoder directly, and connect it as Figure 3. If the encoder drains more than 50mA, use an external Pin Number (Term.) Function Pin Number (Term.) -

Authorized Distributor of Leadshine Technology 4.3 Prepare Controller Prepare a controller with STEP and DIR signal. 4.4 Initialize DB810 Before going on, turn the current LIMIT trimpot a quarter to half of full scale. Turn the GAIN trimpot fully off and turn the DAMP trimpot to a quarter of full scale. -
Page 6: Tuning The Servo
You can detective how the motor behaves in response to an impulse load by There are three trimpots at the side of DB810. They are GAIN, DAMP and LIMIT watching an oscilloscope, as shown in Figure 6. The easiest way to induce a separately for current setting, as shown in Figure 5. -
Page 7: Using Tips
CRITICALLY DAMPED UNDERDAMPED If at any time after that a condition occurs that causes the DB810 to “fault out”, such Figure 6: Response to an impulse load as not being able to complete a step command, the ERR/RES terminal will go to “0”, Slowly increase STEP speed until you get a picture similar to one of the three above, signaling the computer an error has occurred. -
Page 8: Reversing Default Motor Direction
The ERROR output is latched in the “ERROR” state (term. 5 = 0) by the power-on reset circuitry in the DB810. It will stay in this state indefinitely until it is cleared by applying +5V to this terminal for at least 5 seconds. - Page 9 12 months from shipping date. During the warranty before returning product for service. Please include a written description of the period, Leadshine will either, at its option, repair or replace products which proved problem along with contact name and address. Send failed product to distributor in to be defective.
