Applications:
Variable torque, constant torque or constant horsepower
applications. New installations, replacements and original equipment
manufactures (OEM).
Features:
Volts per Hertz or Sensorless Vector Control with peak overload
capacity of 200% and P±D capability. Flexible mounting options with ±P20
enclosure as standard and NEMA 1 kit option. ±ntegral keypad, operator
interface and local speed control. Programming by Groups makes it easy
to navigate and find parameters. Basic Program Group contains the most
common application related parameters. Power ratings up to 30 Hp in both
230V and 460V versions. Built-in braking transistor allows connection to
remote braking resistor for enhanced performance needs.
