BUSVOLTAGETHRESHOLD/BVT
Purpose:
To read and write the DC bus voltage threshold on a MintDrive.
Controllers Supported:

- 0 – 460V
Description:
On MintDrive, if the DC bus voltage drops below the bus voltage threshold, an error will be generated.
This will be reported by the
DRIVEFAULT keyword. The threshold below which an error is generated is
controlled by the
BUSVOLTAGETHRESHOLD keyword. Setting a voltage threshold of zero turns off the
error detection.
The DC bus voltage is the AC bus voltage x Ö2. The current bus voltage can be read with the
BUSVOLTAGE keyword.

CAMAMPLITUDE/CMA
Purpose:
To modify the amplitude of a cam profile
Controllers Supported:

Description:
The
CAMAMPLITUDE keyword allows a cam profile to easily scaled to change to position range of the
slave motion. The slave positions are simply multiplied by the amplitude value, based on the position
within the current cam cycle.
