Example:

BACKLASH.3 = -0.3

BACKLASHINTERVAL.3 = 50

MOVER.3 = 0.5

GO.3

PAUSE IDLE.3

BACKLASHMODE.3 = 1

This sets up backlash compensation on axis 3 of 0.3 mm to be applied over 50 servo cycles. A small

negative move is performed to ensure that the backlash has been taken up in a positive direction;

equivalent to a negative direction home sequence.

The axis must be

idle in order to change the backlash mode and the default backlash mode is off.

Description:

Reads the DC bus voltage on a MintDrive. This is useful on an external 24V MintDrive to check that

the mains voltage is at the correct level before attempting motion.

If the bus voltage is 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.

Example

On a MintDrive with a 240V AC input, the DC bus voltage can be read as follows:

PRINT BUSVOLTAGE

338

The DC bus voltage is calculated as follows:

DC voltage = AC voltage x Ö2
