The MDrive34AC Plus2 Motion Control system offers designers a low cost, intelligent motion controller integrated with a NEMA 34 high torque brushless motor and microstepping drive operating at 120 or 240 VAC.
Unsurpassed smoothness and performance delivered by the MDrive34AC are achieved through IMS's advanced 2nd generation current control. By applying innovative techniques to control current flow through the motor, resonance is significantly dampened over the entire speed range and audible noise is reduced.
The MDrive34AC accepts a broad input voltage range from 95 to 264 VAC, delivering enhanced performance and speed. Oversized input capacitors are used to minimize power line surges, reducing problems that can occur with long runs and multiple drive systems. An extended operating range of -40° to +85°C provides long life, trouble free service in demanding environments.
The MDrive34AC Plus2 Motion Control system adds a versatile array of functions by combining a complete programmable motion controller with our compact and cost effective MDrive34AC Microstepping Drive, adding little cost and no increase in size. Standard offerings include up to 8 general purpose I/O lines (sourcing or sinking) that operate to +24 VDC, one 10 bit analog input, electronic gearing, high speed position capture input/trip output, microstep resolutions up to 51,200 steps per revolution, 0 to 5 MHz step clock rate, and a full featured easy-to-program instruction set.
The MDrive34AC Plus2 Motion Control system communicates over RS-422/485 which allows for point-to-point or multiple unit configurations utilizing one communication port. Addressing and hardware support multiple uniquely addressed units communicating over a single line.
Optional communication protocols include CANopen. The CAN bus is 2.0B active (11 and/or 29 bit) and is capable of all standard frequencies from 10 kHz to 1 MHz. CANopen features include node guarding, heartbeat, SDOs and PDOs. Highlights include variable PDO mapping and extended node indentifier.*
The MDrive34AC Plus2 Motion Control is available with optional closed loop control. This increases functionality by adding stall detection, position maintenance and find index mark.
The closed loop configuration is added via a 512 line (2048 edge) optical encoder with index mark, internal to the MDrive34AC so there is no increase in length. Or, for an expanded choice of line counts and resolutions, closed loop control is available with an interface to a remotely mounted user-supplied external encoder.
In addition to encoder options, the MDrive34AC Plus2 Motion Control has the capability of electronic gearing by following a rotary or linear axis at an electronically controlled ratio, or an output clock can be generated fixed to the internal step clock.
A sealed* version designed to meet IP65 specifications is also available. The sealed assembly allows the MDrive34AC to be used in environments where exposure to chemical, dust and liquids may occur.
Available rotary motor configurations include three motor lengths, an optional rear control knob for manual positioning and an integrated planetary gearbox. A linear actuator version with long life Acme screw is also available.* Interface connections are accomplished using standard industrial connectors.
