Description
FD2 belongs to Full Digital family drives, to be mounted directly on motor end-shield.
Integrated stepper motor allows to simplify cabling and to easily exploit the benefits of absolute magnetic encoder: verify the correct execution of ordered steps, control the motor current with the load, avoid motor stall and other functions described on firmware manual.
FD2 is equipped with configurable I/O’s:
- 6 digital inputs that can be configured as step/direction, quadrature steps, homing sensors, limit switch, start/stop, cycle and sequence selection, enable/disable motor current, etc.
- 2 digital outputs that can be configured as alarm, drive ok, running, etc.
Modbus RTU protocol is available over RS-232 (from 4 800 to 115 200 bps) and RS-485 ( from 4 800 to 921 600 bps).
Suffix A identifies the model equipped with CAN transceiver (e.g. FD2.1A) to communicate with CANopen DSP402 protocol (from 10 kHz to 1 MHz).
Suffix D identifies the model equipped with insulated DC/DC, used to keep the logic supplied also in case of loss of main power supply. This allows to maintain encoder position counting and field bus communication alive.
