Maximum load
The 10 V DC supply is galvanically isolated from the supply voltage (PELV) and other high voltage terminals.
Control characteristics
Resolution of output frequency at 0–590 Hz
Repeat accuracy of precise start/stop (terminals 18, 19)
System response time (terminals 18, 19, 27, 29, 32, 33)
Speed control range (open loop)
Speed control range (closed loop)
Speed accuracy (open loop)
Speed accuracy (closed loop), depending on resolution of feedback device

Control card, USB serial communication
USB standard
USB plug
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 ground connection is NOT galvanically isolated from protective earth. Use only an isolated laptop as PC connection to
the USB connector on the frequency converter.
