Frequently Asked Questions
- What is the difference between V/Hz and FOC control modes?
- V/Hz is simpler and good for pumps/fans. FOC (Field Oriented Control) gives better torque response for precise applications.
- Can I connect this drive to a PLC via EtherNet/IP?
- Yes. The VFAS3-4370PC supports EtherNet/IP for direct connection to Allen-Bradley and other PLCs.
- What does “integrated dynamic braking” mean?
- It means the drive has built-in circuitry to quickly stop the motor by dissipating energy as heat, without needing an external brake resistor.
- How do I replace the backup battery?
- The battery is a standard CR2032. Access the control board and replace it with power disconnected to maintain parameters.
- What’s important when setting up the Safe Torque Off function?
- You must use safety-rated components and wiring. Test the STO function regularly to ensure it meets your safety system requirements.
