Positioning and Power Module for Stepper Motors for ET 200S

  • Entry
  • Associated product(s)

The Phytron company is offering a positioning and power module for stepper motors for the ET 200S system. Please note the information below concerning ordering and support.

The 1-STEP-DRIVE-5A-48V module from Phytron is a stepper motor controller with integrated power section for use with the SIMATIC ET 200S distributed I/O system.

The 1-STEP-DRIVE-5A-48V module can be employed with all PROFIBUS and PROFINET interface modules and also with a ET 200S CPU. All current product releases of the IM 151 interface modules are suitable for operation with the 1-STEP-DRIVE.
Suitable GSD files and an HSP are also available.

A list of permitted terminal modules with which the 1-STEP-DRIVE module can be operated can be found in the user manual of the manufacturer.

The module enables the connection of a 2-phase stepper motor in the 200W power range, up to 5A PEAK, with a supply voltage of 24 to 48V DC.

Example function blocks are available for operation with SIMATIC, which the user can download from the Internet address below and modify to his requirements.

Positioning functions

The 1-STEP-DRIVE features the following positioning functions: 

  • Absolute positioning
  • Relative positioning
  • Reference point approach
  • Endles axis: speed mode / frequency output
  • Selection of the checkback value

Technical specifications of the integrated power output stage

  • Suitable for bipolar control of 2-phase stepper motors in 4,(6) or 8-conductor design (in 4-conductor connection)
  • 5A PEAK phase current with adjustable current steps
  • Supply voltage of 24 to 48V DC
  • Up to 1/512th micro step (physical resolution: approx. 102 400 positions per rotation (0.0035° / step))
  • Maximum stepper frequency: 510 000 steps/sec
  • 2 digital inputs for end and reference switches
  • Diagnostic LEDs (overcurrent, overtemp., drive command or motor runs,...)
  • Short circuit proof, overload protection
  • Data record transfer for power output stage parameterization and diagnostics during runtime
  • Overdrive: Current adaptation for higher clock frequencies
  • Boost: Expandable torque during acceleration and braking
  • Selectable current controller frequency: 18, 20, 22 or 25 kHz
  • Adjustable response in the case of CPU stop

Typical applications:

  • Feeder systems of assembly lines
  • Transfer lines
  • Building automation
  • Printing machines
  • Paper and textile machines
  • Positioning on X-Y table
