STEPNET - DIGITAL STEPPER MOTOR AMPLIFIER WITH ENCODER FEEDBACK

The Stepnet stepping motor drives are the modern digital stepper motor controllers and can be seen as brothers of the Xenus and Accelnet servo controllers from Copley Controls. There are stepper drives for mains operation at 1x 110 - 240Vac as well as for DC supply (24Vdc to 90Vdc).

The Stepnet stepper motor controllers are 100% software-compatible with the Xenus controllers and offer the same functionality, i.e. they can completely control individual axes with their indexer functionality. Communication with individual commands in ASCII format via the RS-232 interface is possible, as well as pre-programming and storing entire programs and controlling them via inputs.

 

The possibility for a real servo mode should be emphasized, i.e. stepper motors with an AquadB digital encoder can be operated as multi-pole servo motors.

 

The Stepnet stepper controllers are also equipped with a CAN interface as standard (CANopen, DSP402 profile). The new Stepnet Plus controllers also offer an optional EtherCAT interface. The connection to these two fieldbus systems opens up new possibilities for automation concepts with distributed intelligence.

 

In general, the following characteristics can be noted for the stepper controllers of the Stepnet series:

  • operation at 14Vdc to 90 Vdc / 110VAc to 230Vac (depending on model)
  • currents from 0.7Arms to 8.5Arms continuous
  • efficient control: vector control (info vector control )
  • efficient commissioning: CME software with oscilloscope and auto-tuning and auto-phasing
  • easy integration into central control concepts: pulse/direction interface, +/-10V, PWM
  • efficient use as single axis controller: powerful indexer via RS232 interface (programs also addressable via I/O)
  • easy integration into distributed control concepts: CANopen (optional CANopen libraries for C++ (data sheet CML ) and COM objects (data sheet CMO ))

Further accessories are available:

  • CAN-PCI card with two channels (parameterization via CAN possible), see CAN-Interfaces
  • CAN I/O processor for PCB mounting: 8 inputs for CAN address selection, 72 digital I/O, 12 analog inputs,12 PWM outputs, 2 outputs for status LED, RS-232), see CAN-Interfaces I/O-Module
