Information

Overview Manuals Application Notes Product Applications Installation Steps and Wiring

Features:

  • 16-bit microprocessor controlled SVPWM output
  • Low noise;carrier frequency up to 10kHz
  • Controlled reversing
  • 2 inputs and 1output terminal for external controls
  • Adjustable V/Fcurve
  • RS-485 communication(Baud rate 9600)
The Delta VFD007L21A is a compact, high-performance AC variable frequency drive belonging to the VFD-L Series, specifically for small-scale industrial applications where space and cost-efficiency are critical. This "Sub-fractional" drive is ideal for simple motor control tasks, such as those found in conveyors, fans, and small processing machinery. Its 1-phase 230V input makes it highly versatile for use in facilities that may not have access to 3-phase power, while still delivering a stable 3-phase output to the motor.

The VFD007L21A Delta AC variable frequency drive (VFD) may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

Mounting: Install the VFD vertically on a flat, vertical surface using screws to ensure proper heatsink ventilation. Allow sufficient space around the unit for cooling.
Input Power: For the VFD007L21A (1-phase 230V), connect the input power to terminals R/L1 and S/L2.
Motor Output: Connect the 3-phase motor leads to terminals U/T1, V/T2, and W/T3.
Grounding: Ground the VFD unit using the ground terminal (terminal E) to comply with local codes.

Technical notes

VFD007L21A provides multi-function control circuit terminals including digital inputs M0 (Forward/Stop), M1 (Reverse/Stop), M2 (Reset), and M3 (Multi-step 1), all with +18V internal power supply and 4.7kΩ pull-up resistors, plus multi-function relay output contacts RA/RC rated for 120VAC/28VDC at 3A with factory default setting as Fault Indication.

FAQs

  • What is VFD007L21A?

    +
    The Delta VFD007L21A is a 1 HP, 230V single-phase input/three-phase output variable frequency drive (VFD) from the VFD-L series.
  • Can I connect a 1-phase motor to the VFD output?

    +
    No. The VFD007L21A outputs 3-phase power. It cannot run a standard 1-phase AC motor.
  • How do I change the direction of the motor rotation?

    +
    Switch (swap) any two of the three motor leads connecting to the VFD output
  • Does it have built-in communication?

    +
    Yes, it features an RS-485/Modbus RTU interface, allowing you to connect it to PLCs or remote control systems
