Product Description


The model P808A high performance microstepping drive suitable for 2-phase and 4-phase hybrid steppers requiring a drive current of up to 7.7A / phase.

The design features an advanced bipolar constant-current chopper circuit with current control Technology. suitable for stepper motor control applications requiring low noise, low vibration, high speed and high precision.  TTL compatible and optically isolated input signals.

Suitable for a wide range of stepping motors of size NEMA 17,23, 34 and 42.  Usable for various kinds of machines, such as X-Y Tables, Labeling machines, laser cutters, engraving machines, and pick-up devices; particularly useful in applications with low noise, low vibration, high speed and high precision requirements.

This drive uses differential inputs to increase noise immunity and interface flexibility.  Single-ended control signals from the indexer/controller can also be accepted by this interface.The input circuit has built-in high-speed optocoupler, and can accept signals in the format of line driver, open-collector, or PNP output.  Line drive (Differential) signals are suggested for reliability.

Guides

Guide to Stepper Motor Drive Selection

Q: How can I work out which stepper motor drive I need?
A: If you are new to these products we suggest that you start by reading our technical guides to stepper motors and stepper motor drives. These may be downloaded through the Technical section of this website. With this overview you will then need to review the motor and drive product ranges, e.g., unipolar or bipolar drive mode, drive voltage and current, size and style of drive etc.

Q: Are your products suitable for worldwide use?
A: In general, yes, as they are DC powered and designed to International Standards.

Q: Are the products compliant with EU safety standards and directives?
A: Yes, we apply all relevant European Directives to our designs, and where appropriate, carry out EMC testing in independent laboratories.

Q: Are the products compliant with the RoHS Directive?
A: Our materials and manufacturing processes were converted to RoHS-compliance several years ago. All of our current products are fully RoHS-compliant.

Q: Do you accept credit card payment for goods?
