    These Leeson Speedmaster 2 Inverters utilize the latest technology and power conversion circuitry. Use with AC vector motors with open loop flux vector designs. Leeson Speedmaster vector drives can be used in a wide range of applications, including food processing, machinery, material handling, and HVAC systems.

    Easy to install and operate, you can program the Vector control with the easy-to-use remote keypad. Program through a computer using TechLink software, available free from www.leeson.com, or through the innovative EPM programmer.

    Speedmaster Drive FAQs:

    • How much space is required around the variable speed drive?

    Depending on the VFD series that is being used, maintain the following spacing around each VFD: Micro Series: 2 inches below 5 HP; 4 inches for 5-25 HP; 6 inches for 25-60 HP; 8 inches above 60 HP. SM Plus Series & SM-Series: 1 inch on each side and 2 inches on the top and bottom for 10 HP and below; 1inch on each side and 4 inches on the top and bottom for 15-25 HP.

    •  What is the maximum distance the motor can be from the VFD?

    The motor should be located as close to the VFD as possible (100 feet or less). For applications where the motor is more than 100 feet away from the drive, a load reactor or dV/dt filter should be installed. As motor lead length increases, voltage spikes generated by the VFD’s output transistors become amplified, and may result in motor failure. Adding an output reactor or dV/dt filter reduces the spikes.

    •  Can you program a VFD while it is running?

     Yes, but the changes will not take effect until after the VFD is restarted.
