Stepper motor controller/driver steps at 13kHz

The PD 626 is a low cost integrated controller and driver for stepper motors.

The PD 626 is a low cost integrated controller and driver for stepper motors.

It is the latest addition to the M36 family of DIN rail mounted, clip-together P-Net process control modules from Proces-Data.

The unit directly drives a unipolar stepper motor requiring up to 1.8A per winding.

For larger stepper motors the PD 626 can be used as a controller for an external grey-code driver.

The module takes care of ensuring that defined levels of acceleration or deceleration to reach a specified target position, or target speed up to 13,000step/s are met.

All parameters are set via the P-Net (IEC61158/4) fieldbus interface.

A 32bit step position register together with a comparing set point register, provides precise position control over 2 billion step positions in each direction.

For a 1.8-degree step motor this means a repeatable control range of 10 million revolutions.

The controller can be configured for half or full stepping with one or two phases.

Two high-speed digital inputs enable dynamic control of starting and/or stopping the motor to be configured.
