6 General Specifications
6.1 Protection and Features
-
All inputs, outputs and supply voltages are
protected against short circuit.
-
All inputs, outputs and supply voltages are
galvanic isolated from high voltages such as
mains supply and motor voltage (PELV).
-
Encoder signals are monitored during operation
and standstill.
-
Customer specific application programs can be
copy protected.
-
All MCO 305 parameters including user defined
application parameters are accessible via the VLT
AutomationDrive LCP.
-
MCO 305 can be combined with other VLT
AutomationDrive options e.g. PROFIBUS and
DeviceNet interface.
-
All digital inputs and outputs are galvanic
isolated from the internal electronics and can be
sourced from an external 24V power supply.
