Description
Four independent command outputs
Output range: ±10VDC (±10mV).
Resolution: 14-bit (accuracy ±1.22mV).
Output current: 1mA maximum
Update interval: Immediate
Mint and the Mint Motion Library use the analog outputs to control servo drives.
Demand outputs 0 to 3 correspond to axes 0 to 3. The analog outputs may be used to drive
loads of 10kΩ or greater. The outputs are referenced to the internal ground and are not
opto-isolated. Shielded twisted pair cable should be used. The shield connection should be
made at one end only.
