Main characteristics

Features

  • Dual H bridge, bipolar chopper, 40 kHz PWM
  • AC and DC power supply
  • DIP switch to configure motor current and resolution (steps/rev)
  • Auxiliary power supply for micro-processor and field buses
  • Step/dir and quadrature steps inputs
  • Start/stop, cycle/sequence selection
  • CANopen DSP402 and Modbus RTU
  • Firmware and parameters programming over field-bus
  • Relays to act as electric brake when powered off.

Description

FD4 belongs to Full Digital family drives, to be installed in an electric cabinet.

FD4 is equipped with configurable I/O’s: 

  • 2 differential inputs that can be set up as step, direction, quadrature steps, start, stop, etc., 
  • 4 single ended inputs that can be configured as homing and limit switches, cycle and sequence selection, enable, disable current, etc.
  • 2 outputs that can be configured as alarm, running, etc. 

Using DIP switches located on the front panel it is possible to set up motor current and resolution (steps/revolution) or the field-bus node address.

The drive can be controlled and monitored through RS-232 (from 4 800 to 115 200 bps) and opto-insulated RS-485 (from 4 800 to 921 600 bps) over Modbus RTU protocol.

Suffix A identifies the model equipped with transceiver CAN opto-insulated (es. FD4.1A) to communicate over CANopen 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.

Suffix R identifies the model equipped with relays to act as electric brake in case of loss of power.
