Leadshine's fully digital AC servo drive ACS806 is a brushless servo motor drive designed to be a drop-in replacement for stepper drives. It's a match to our MOT-455 400 W brushless servo motor.

The drive uses an 32-bit DSP with an advanced control algorithm. The input signals are industry-standard pulse and direction signals, allowing the drive to be used in existing stepper or servo systems without require a change of controller. The ACS806 offers high precision, high speed and high reliability performance, and is widely used in CNC machines, industrial robotics, inkjet printers and engraving machines. A built-in controller can be used for testing and tuning.

PC based and handheld configuration & tuning tools can meet different tuning environments or requirements. Use the LSK-001 cable with the Protuner software (download link below) to tune the drive.

Tuning:

Tuning parameters will depend on the motor used and the system the motor is installed in, but a table of good starting values when using the MOT-455 is shown below. The current loop tuning requires a password. The default password is "654321".

Brake Resistor:

In most of the cases brake resistor isn't required. In cases where the motor is turning a large rotational inertia and requires rapid deceleration, the regenerated power may raise the voltage enough to trip the driver into over voltage protection. A brake resistor can be attached to the drive to dissipate the excess energy. The ACS806 contains internal chopper circuitry that activates the brake resistor only when required. A typical brake resistor would be 75 Ω, 200 W.
