Rapid Positioning with Smart Stepper Motor Drives

 | 

Stepper motors are always ideal when a lot of torque and precise, reliable positioning is needed at low and medium speeds. The new PANdrive is pushing the envelope for stepper motor applications to high-speed positioning with up to 5000 rpm.

Trinamic's TMCM-1241 Module

Hamburg, 16 July 2018 - TRINAMIC Motion Control GmbH & Co. KG, a leading supplier of semiconductors, electronics and mechatronic solutions in the fields of motor and motion control, announces the extension of the successful PANdrive product line by the PD42-3-1241 and the module TMCM-1241. The drive is equipped with a high current NEMA17 motor for fast, dynamic positioning.

"We entered the market of smart motors 15 years ago and have been at the forefront of integration ever since. With this latest product, our line of smart stepper motor drives is updated with the latest and leading-edge technologies of current control and sensorless diagnostics.” – Michael Randt, Founder and CEO of Trinamic

The product features Trinamic’s second generation StealthChop, the silent stepper motor drive technology for quiet stepper motors, as well as SpreadCycle for smooth motion control. CoolStep, the sensorless load-dependent current control, ensures energy-efficient operation of the motor while the magnetic SensOstep encoder provides step-loss detection for safety – even in standstill.

Developed for a +10V to +30V DC operating voltage at up to 3A RMS phase current, the PD42-3-1241 PANdrive and TMCM-1241 module can reach up to 5000 rpm. As such, the drive provides superior performance wherever precise positioning at high speed is required. Accessing this performance is easy using the free TMCL-IDE, allowing for easy implementation of a standalone program flow and remote-controlled operation like all other Trinamic PANdrives and modules. Host communication is possible via the RS485, USB, or CAN interface using TMCL or the optional CANopen protocol.

An integrated SixPoint ramp generator allows for precise and rapid positioning – even in environments where parameters and target positions must be changed during motion. The drive has L+R reference switch inputs and comes with StallGuard2 for sensorless homing.
