ASDA-A3

2.8 Selecting the regenerative resistor

When the direction of torque is different from the direction of rotation, the energy generated
returns to the servo drive from the load. This energy is turned into electricity in the capacitance of
the DC Bus and thus increases the voltage. When the voltage reaches a given value, it is
consumed by a regenerative resistor. The servo drive has a built-in regenerative resistor.
You can also use the external regenerative resistor if needed.
(1) Moving direction of the object; (2) Direction of torque; (3) Regenerative energy
The built-in regenerative resistor in the ASDA-A3 is as follows:
