The compliance tested TM StepDrive is plug and play compatible with the PROFINET-based Siemens PLC, allowing the seamless addition of motion control to automation systems in process control, packaging machinery, pick and place assembly lines and more. Available as a 24…48 VDC supplied microstepping drive with adjustable peak current up to 5 Amps, or as an indexer module with pulse and direction output for interfacing with more powerful external drive stages, the TM StepDrive is programmed from Siemens’ STEP®7 or TIA Portal® - as an application program or as a Simatic Technology Object.
The Siemens approved stepper motor drive is suitable for 2-phase stepper motors with 4-, 6- or 8-lead wiring and offers selectable microstepping resolution from full-step to 1/256 steps (51.200 pulses per rev). The maximum step frequency is 250,000 steps/rev and a separate rotary encoder and a counter in the Siemens PLC may be included to provide position verification for higher microstepping rates. The controller modes available include relative and absolute positioning, move to reference point, variable free-run speed, position setting and motor/emergency stop. The drive stage version includes 100 mA adjustable increments up to its 5 Amp peak current rating which equates to around 200 W of shaft power.
The controller has three digital inputs for limit and reference switches, whilst digital outputs of clock, direction and run facilitate feedback to the PLC. The TM StepDrive is packaged in the same rack mounting design as the compact and modular SIMATIC ET 200SP HA. Functional safety such as Safe Torque Off (STO) may be included with the drive using the distributed I/O system’s EN 61508 certified safety modules.
The scalable and highly flexible SIMATIC ET 200SP HA is distributed I/O system that offers straightforward operation and features a compact design for maximum control cabinet economy. With high-speed PROFINET communication, the PLC offers exceptional performance and is widely used across process and automation industries.
