4.2.2 Analog outputs
The four analog outputs are available on connector X13, as shown in section 4.1.1.
 Four independent bipolar analog outputs.
 Output range: ±10 VDC (±0.1%).
 Resolution: 12-bit.
 Output current: 2.5 mA maximum per output.
 Update frequency: 10 kHz maximum (adjustable using the LOOPTIME keyword, factory
default 1 kHz).
Mint and the Mint Motion Library use analog outputs Demand0 to Demand3 to control drive
amplifiers. Demand outputs 0 to 3 are used by axes configured as servo (see section 5.4.1).
A Demand output may be used as a general purpose analog output if it is not assigned to a
servo axis - see the DAC keyword in the Mint help file.
The analog outputs may be used to drive loads of 4 kΩ or greater. Shielded twisted pair
cable should be used. The shield connection should be made at one end only.
