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.
