11 Functions
11.1 Inputs
The
pulse
Control
, Motor direction,Boost , Activation and Reset inputs are electrically
insulated by optocoupler from the MSX
+
supply voltage (+U
B
). This assures best noise
suppression between control and power circuit. The signals are active, when current flows
through the optocoupler.
11.1.1 MSX
+
5 V Standard and MSX
+
5 V RESET Inputs
All inputs include an optocoupler with series resistors 2 x 180
The MSX
+
inputs are controlled via open-collector. The supply voltage of the optocouplers,
5 or 24 V, is connected to pin 10ac (admissible range: 4...32 V
DC
).
Open Collector controlling (5 V)
11.1.2 MSX
+
24 V Input
All inputs include an optocoupler with series resistors 2 x 2.2 k
.
The MSX
+
inputs are controlled via open-collector. The supply voltage of the optocouplers,
of 24 V, is connected to pin 10ac.
Open Connector controlling of 24 V
