4.3.2 Analog outputs

The four analog outputs are available on a range of pins, as shown in section 4.2.1.

HFour independent analog outputs.

HOutput range: ±10VDC (±0.1%).

HResolution: 12-bit.

HOutput current: 10mA maximum.

HUpdate frequency: 10kHz maximum (adjustable using the LOOPTIME keyword, factory default 1kHz).

MintMT and the Mint Motion Library use analog outputs Demand0 and Demand1 to control drive amplifiers. Demand outputs 0 and 1 are used by axes configured as servo (see section 6.3.1). The Demand2 and Demand3 outputs may be used as general purpose analog outputs. See the DAC keyword in the MintMT help file.

The analog outputs may be used to drive loads of 1kΩ or greater. Shielded twisted pair cable should be used. The shield connection should be made at one end only.
