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.
