MCD+
Compact stepper motor power stage with
ServiceBus
The MCD+ is a bipolar power stage for driving
2 phase stepper motors. The operation parameters - phase currents, step resolution and
preferential motor direction - are programmable by rotary switches or in the ServiceBus
mode.
+
The MCD is designed for power supplies
from 24 to 70 VDC.
The control pulse, motor direction, boost, activation and reset inputs are compatible with
push-pull or open collector signals. The control inputs are electrically insulated from the
supply and motor voltage.
A special feature of the MCD+ offers 3 terminals for each signal input. Thus separate
input terminals for 5 V and 24 V are available.
In Focus
Application
The MCD+ is suitable for up to 450 Watts of
shaft power that is ideal for controlling spindle and toothed belt drive systems for mechanical handling or assembly applications. The
high step resolution makes the MCD+ the best
solution for applications that have especially
high demands on precision, smoothness and
durability.
Highlights
Rotary switch mode
ServiceBus mode
The run and the stop current can be changed between two ranges by the current
range switch. These phase currents can be
set in 15 increments up to 9 APEAK. In this
operating mode the step resolution can be
adjusted from full step up to 1/20 step.
All settings are entered at the PC, which is
easy to do with the free phytron software
ServiceBus-Comm® for Windows®.
