- Connects a ControlLogix controller to one SA3100 PMI chassis
- Supports velocity, position, and torque control rather than general-purpose I/O
- Uses a documented software and firmware set for drive commissioning
1756-DMA31 occupies the control boundary between a Logix project and an SA3100 drive installation. Its role is defined by the paired PMI chassis and the selected control mode.
The official release notes focus on firmware/software compatibility and two commissioning hazards: an incorrect controller communication format for volts-per-hertz operation and transient PMI faults during power cycling.
Before installation or replacement, verify the SA3100 power-unit class, PMI chassis allocation, SynchLink arrangement, controller format, firmware, and archived DriveExecutive project.
Availability, condition, price, and shipping time for 1756-DMA31 are confirmed during quotation.
