Motor Current

The drive current must be set to match the motor. First, determine the rated current for the motor. You can operate a motor at less than the rated current. It will have less Torque than it would at the rated current, but will run cooler and make less audible noise.

Your drive is equipped with a feature that automatically reduces the motor current anytime the motor is not moving. This reduces motor and drive heating. For example, setting the idle current to 50% reduces drive heating by about 50% and lowers motor heating by 75%. This feature can be set at any of four levels: 0%, 25%, 50% and 100%.

In the PSMCC software, the current is controlled in the main window by the panel on the upper left side of the screen. To adjust the current setting, just slide the scroll bar left or right. Precise adjustments can be made by clicking on the arrows at each end of the scroll bar.

The 100% setting is useful when a high holding torque is required, as the drive does not reduce the current at all. The 0% setting is for applications in which no holding torque is required.
