4.2.2 Analog outputs
The four analog outputs are available on connector X13, as shown in section 4.1.1.
H
Four independent bipolar analog outputs.
H
Output range: ±10 VDC (±0.1%).
H
Resolution: 12-bit.
H
Output current: 10 mA maximum.
H
Update frequency: 1 kHz.
Mint and the Mint Motion Library use analog outputs Demand0 to Demand2 to control local drive
amplifiers. Demand outputs 0 to 2 are used by axes configured as servo (see section 5.5.3). All
of the outputs may be used as general purpose analog outputs, provided they have not been
assigned to an axis - see the
DAC
keyword in the Mint help file.
The analog outputs may be used to drive loads of 1 k Ω or greater. Shielded twisted pair cable
should be used. The shield connection should be made at one end only.
