Logic Supply Voltage - maxon motor EPOS4 Module 50/5 Hardware Reference Manual

4.1.3
The Module features a logic supply voltage input. Its voltage range is 10...50 V and must be either
sourced separately or by the power supply voltage.

TVS D
If the logic supply voltage is sourced separately, a transient voltage suppressor diode (D2) at the logic
supply voltage input can be connected to protect the module against overvoltage.
C
APACITOR
Use an electrolytic capacitor (C2) if the logic supply is sourced separately. This will avoid oscillations
caused by supply cable inductance or the Module's built-in capacitors that could lead to a voltage over-
shoot at power plug-in.
