1-3-1 CMC-FB01 -- Fiber Communication Card
When the AC motor drive is used in parallel control, the master and slave drive communicate with
each other through optical fiber. This communication relies on the SPI interface between the MCU
and the FPGA optical fiber card. The transmission and reception of signals are completed during each
PWM cycle.
⚫ In C2000 series, the optical fiber communication card is installed in
Slot 2 by default. If you need to install the communication card in
Slot 1, contact Delta for further information.
⚫ Delta provides two length options for the required fiber optic
communication cables.
