Copley Controls: Stepnet AC (STX Series)
20-75 VDC & 115-230 VAC Digital Drives for Stepper Motors
Description
Stepnet AC is a compact, AC powered microstepping drive for control of hybrid stepping motors. It operates as a stand-alone driver taking Pulse/Direction or CW/CCW inputs from an external controller or as a distributed drive on a CANopen control network. In Servo mode a stepper with encoder operates as a brushless servo motor in position, velocity, or torque modes.
Indexing mode simplifies operation with PLC’s that use outputs to select and launch indexes and inputs to read back drive status. A single serial port on the PLC can send ASCII data to multiple drives to change motion profiles as machine requirements change.
CAN bus operation supports Profile Position, Profile Velocity, Profile Torque, Interpolated Position, and Homing. Up to 127 Stepnet AC drives can operate on a single CAN bus and groups of drives can be linked via the CAN so that they execute motion profiles together.
Input command signals include ±10 Vdc (torque, velocity, in Servo Mode), PWM/Polarity (torque, velocity in Servo Mode), or Step/Direction and CU/CD (microstepping).
Separate ports are provided for differential or single ended encoder connections. The active input is programmable.
Twelve digital inputs include a dedicated drive Enable, motor overtemp switch, and 10 general purpose inputs. Two of the high-speed inputs are programmable as differential or single-ended.
