Mclennan is launching a new pin-compatible version of its popular MSE570 Eurocard series stepper motor drive that adds selectable microstepping resolution and improves speed/torque capability. The completely redesigned MSE570M drive offers much-improved smoothness and lower motor resonance while retaining all of the useful control and monitoring features of the previous version, the MSE570EVO2.
With up to 4A per phase available, the new drive boasts 15 per cent more useful torque than its half-step predecessor, making it a compelling proposition as a drop-in replacement for older machines where improved throughput or quieter and smoother performance is desirable. The new drive will also suit new OEM or end-user applications where its competitive price and the convenience of the Eurocard format is essential.
The new microstepping drive also features improved power input levels with provision for up to 48V DC regulated supply (up to 52V DC unregulated). Its bi-polar chopped constant current drive stage is compatible with permanent-magnet or hybrid stepper motors with 4, 6 and 8 leads – typically with up to NEMA 34 frame sized microstepping motors. DIP switches on the MSE570M are used to select a number of user-adjustable features including full/half/microstep resolution (up to 51,200 steps/rev), current control (from 0.25 to 4A per phase), standstill current (0 to 100 per cent in four stages), thermal protection settings, direction and drive disable.
Further flexibility is offered with switchable signal level input and output settings (5V or 12V logic) with the drive configurable for use with step-and-direction signals that include CMOS, TTL open collector, opto-isolated or switch-type inputs. Four surface-mounted status LEDs indicate power, drive disabled, over-temperature and overload faults.
As well as manufacture the MSE570M and other motion control components, McLennan has distribution partnerships with a select number of global motion control manufacturers. The complete range includes DC brushed and brushless servomotors, stepper motors and associated drive technologies, together with motion controls, gearheads and miniature power transmission components. Mclennan offers these products with full technical support as component-level systems or, using its own in-house design and assembly facilities, the company is able to integrate these products into complete customised mechatronics assemblies and motion control systems.
