Description
Four independent command outputs
Output range: ±10VDC (±0.1%).
Resolution: 14-bit (accuracy ±1.22mV).
Output current: 1mA maximum
Update frequency: Immediate
MintMT and the Mint Motion Library use the analog outputs to control servo drives.
Demand / Command outputs 0 to 3 correspond to axes 0 to 3. The analog outputs may be
used to drive loads of 10k
Ω or greater. The outputs are referenced to PC system ground.
Shielded twisted pair cable should be used. The shield connection should be made at one end
only.
