3 Short Overview
– the MSX
+
Power Stage
The power stage type MSX
+
is used for bipolar control of two-phase stepper motors at 15
A
PEAK
and 60 to 120 V
DC
with Phytron´s well-tried technology, the enhanced 4 quadrant
chopper type current control.
The MSX
+
is designed for 19"/3U racks and connected by a 48-pin connector (type F) acc.
The + of the power stage ZMX
+
stands for “operation with ServiceBus” by ServiceBus-
Comm
TM
for Windows
®
. The configuration software is included in delivery for easy use of
all setting options.
The operating parameters
– run current, step resolution and preferential direction – can be
set either by rotary switches (rotary switch mode) or by ServiceBus (ServiceBus mode).
The ServiceBus enables configuration, programming and diagnostic via PC.

Run and stop current can be individually set in 100 mA steps via ServiceBus. The Boost
current is activated via ServiceBus, too.
The MSD2
+
power stage automatically switches back to stop current if no control pulses
arrive.
