Communication & Integration
The FANUC VFAS3-4015PC includes (2) Ethernet ports (RJ45) and (1) RS-485 port (RJ45), supporting EtherNet/IP, Modbus TCP, Modbus RTU Slave, and a non-secure HTTP webserver. Port speeds reach 10/100 Mbps for Ethernet and up to 38.4 kbaud for RS-485, enabling flexible connectivity to PLCs, HMIs, and SCADA systems.
For advanced applications, optional EtherCAT, encoder, and I/O cards are available, expanding the drive's capabilities without requiring a full hardware replacement.
I/O and Control
This drive offers a rich set of I/O options:
-
Analog Inputs: 3 channels (current/voltage), 11-bit resolution, 0–20 mA / 4–20 mA or ±10 VDC
-
Analog Outputs: 2 channels, 10-bit resolution, 0–20 mA / 4–20 mA or 0–10 VDC
-
Discrete Inputs: 8 points, 24 VDC, sinking/sourcing
-
Discrete Outputs: 3 relay outputs (1 Form C, 2 Form A), 250 VAC / 30 VDC, 2 A per point
The input signal accepts 4–20 mA, voltage, potentiometer, or pulse train, while the PWM output ensures precise motor control.
Installation & Mounting
The FANUC VFAS3-4015PC is designed for panel or wall mounting, with a compact A1 frame that saves valuable cabinet space. It includes a built-in DC reactor, EMC filter, and conduit box to simplify installation. Screw terminals provide secure wiring connections. Ensure adequate airflow around the drive to maintain the -15 to 50 °C temperature rating.
Maintenance & Reliability
To maximize uptime, perform routine inspections of the cooling fans and air filters. The integrated EMI filter and STO function enhance safety and reduce electromagnetic interference. With proper maintenance, this drive delivers long service life, reducing total cost of ownership.
Selection Guide
When selecting a replacement or new drive, verify the voltage, horsepower, and control mode requirements of your motor. The FANUC VFAS3-4015PC is compatible with 3-phase induction and permanent magnet AC motors. For additional I/O or communication needs, consider the optional EtherCAT, encoder, and I/O cards.
