Control card performance
Scan interval 5 ms
Control card, USB serial communication
USB standard 1.1 (Full speed)
USB plug USB type B “device” plug
CAUTION
Connection to PC is carried out via a standard host/device USB cable.
The USB connection is galvanically isolated from the supply voltage (PELV) and other high-voltage terminals.
The USB connection is not galvanically isolated from protection earth. Use only isolated laptop/PC as connection to the
USB connector on the frequency converter or an isolated USB cable/converter.
Protection and Features
•
Electronic thermal motor protection against overload.
•
Temperature monitoring of the heat sink ensures that the frequency converter trips if the temperature reaches a
predefined level. An overload temperature cannot be reset until the temperature of the heat sink is below the
values stated in the tables on the following pages (Guideline - these temperatures may vary for different power
sizes, frame sizes, enclosure ratings etc.).
•
The frequency converter is protected against short-circuits on motor terminals U, V, W.
•
If a mains phase is missing, the frequency converter trips or issues a warning (depending on the load).
•
Monitoring of the intermediate circuit voltage ensures that the frequency converter trips if the intermediate circuit
voltage is too low or too high.
•
The frequency converter is protected against earth faults on motor terminals U, V, W.
