Next generation stepper drive with AC/DC operation
The Danaher Motion P7000 stepping motor drive now available from Micromech is the latest upgrade of their digital step motor control
The series of course includes optically isolated step and direction inputs and the drives are configured by either on-board switches or via the Graphical User Interface (GUI).
This means a wide range of stepper motors can be set up with the on-board switches as the GUI is perfect when using any manufacturers alternative motor type or one with a unique winding.
• Open Loop Stall Detect allows detection of a stalled motor without an encoder or resolver: it can also detect the motor position shifts while at rest.

There are two families of drives, first the DC version a modular micro-stepping drive for operation with NEMA size 17, 23 and 34, 2 phase stepping motors.
This package operates over a 20-75 Vdc and be configured up to 5A rms per phase.
Next is the AC step drive a self contained micro-stepping drive for operation with NEMA size 23, 34 and 42, 2 phase stepping motors.
This package is powered at 120 or 240 Vac and can be configured up to 3A rms per phase.
Options are available for a serial cable connector kit, DeviceNet connector option Phoenix or Euro, position node, DeviceNet with indexing or CANopen with indexing.
