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 10kΩ 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.
