Melles Griot 17MST001 Single Axis Stepper Motor Controller Module

The Melles Griot 17MST001 is a single-axis stepper motor controller module engineered for precise positioning and motion control in automated and semi-automated environments. Built as part of Melles Griot's modular control electronics ecosystem, this module delivers full microstep control of stepper motor drive and park parameters with factory defaults optimized for most applications. Advanced users gain access to fundamental low-level parameter adjustment: initial velocity, final velocity, acceleration, deceleration, backlash correction, and park position drive current.

Technical Specifications

• Output Current: 1 A


• Dimensions: 12 HP (61 mm) width × 3U (134 mm) height × 220 mm depth


• Motor Drive: Full microstep control for stepper motor positioning


• Limit Switch Inputs: Supported


• User-Adjustable Parameters: Initial velocity, final velocity, acceleration, deceleration, backlash correction, park position drive current

Key Features Lead screw error compensation uses stage-specific calibration data measured with 1-nm resolution laser interferometry. Multi-point calibration tables correct for repeatable mechanical errors, delivering absolute accuracy comparable to linear encoder systems without the added cost.

Typical Applications Optoelectronic production and manufacturing environments requiring automated multi-axis positioning and motion coordination.

Compatibility & Integration The 17MST001 drives stepper-motor stages in Melles Griot's nanopositioning product range and integrates into modular system architectures. A single controller manages up to 16 racks, expandable to 64 racks, supporting up to 448 individual modules via high-speed CAN interface. Compatible with companion modules including the 17MPZ001 (Piezoelectric Control Module) and 17MNA001 (Nanotrak Autoalignment Module). Installs in main racks such as the 17MMR001.
