Encoder input accuracy (1–11 kHz)
Maximum error: 0.05% of full scale
The pulse and encoder inputs (terminals 29, 32, 33) are galvanically isolated from the supply voltage (PELV) and other high-
voltage terminals.
1) FC 302 only.
2) Pulse inputs are 29 and 33.
3) Encoder inputs: 32=A, 33=B.

USB plug
USB type B 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.
