PD 626 Stepper motor controller and driver

 

Specific Features

The PD 626 is an integrated controller and driver for stepper motors.

It can directly drive a unipolar stepper motor having up to 1.8A windings.

The software in the controller permanently controls the acceleration or deceleration to reach the target position or the target speed.

 

Individual control parameters for each rotation direction are provided

Integrated high-speed limit inputs, enable configurable motor control events to be executed on the raising or falling edge of each input.

Used with base module BM 005 provides easy-to-use DIN-rail mounting.

 

·           13000 Hz stepping rate.

·           1.8 A per winding by integrated driver.

·           Half stepping.

·           Single full stepping.

·           Dual full stepping.

·           Permanent acceleration / deceleration control.

·           Target speed mode.

·           Target position mode.

·           High-speed inputs for motor control triggers.

·           32 bit resolution; allowing a single move command to span 2 billion steps in each direction.

·           Wide power supply range.

·           Wide temperature range.

·           2 LEDs for power On and Error indication.

·           4 LEDs for motor control status.

·           2 LEDs for limit input status.
