Copley Controls: Stepnet Plus Panel EtherCAT, 1-Axis (TEL Series)
14-90V VDC EtherCAT Drive for Stepper Motors
Stepnet Plus TEl is a high-performance DC powered microstepping drive for control of hybrid stepping motors via EtherCAT using the CAN Application protocol for EtherCAT (CoE). Microstepping modes are Profile Position, Interpolated Position Mode (PVT), and Homing. With encoder feedback, the TEL can operate a stepper as a brushless servo motor, enabling Cyclic Sync Position/Velocity/ Torque operation.
As well as operating on EtherCAT networks, the TEL also supports the following traditional control modes: step/direction, RS-232 ASCII, master encoder for gearing and camming, digital input commands to initiate predetermined motion sequences.
Drive commissioning is fast and simple using CME 2⢠software operating under WindowsŽ and communicating with the TEL via RS-232 or an EtherCAT network.
Feedback from incremental and absolute encoders is supported. A multi-mode encoder port functions as an input or output depending on the driveâs basic setup. As an input it takes feedback from a secondary encoder to create a dual-loop position control system or as a master encoder for driving a cam table.
As an output, it buffers the digital encoder signals from the motorâs digital encoder and eliminates split cables that would be needed to send the signals to both drive and control system.
There are seven non-isolated inputs and four opto-isolated digital inputs that are bipolar types, sourcing or sinking current into a common connection that can be tied to ground or +24V. [IN1] defaults to the drive Enable function and is programmable to other functions. The other inputs are programmable. All inputs have programmable active levels. Three opto-isolated outputs [OUT1~3] have individual collector/emitter connections. An isolated MOSfET output [OUT4] is programmable to drive a motor brake or other functions and has an internal flyback diode for driving inductive loads.
Drive power is transformer-isolated DC from regulated or unregulated power supplies. An AuxHV input is provided for âkeep-aliveâ operation permitting the drive power stage to be completely powered down without losing position information, or communications with the control system.
