Specifications & Enclosure

• Rated Horsepower: 0.25-1.0 HP.
• Rated Voltage: 380-460 VAC.
• Enclosure Type: NEMA 4/12.
• Enclosure Size: Size B.
  • Dimensions (Size B): 301.7 mm (11.88 in) H x 160.1 mm (6.3 in) D x 222.3 mm (8.75 in) W.

Key Parameters & Adjustments

• Minimum Speed (F-03 Parameter):
  • Range: 3-30 Hz.
  • Step Size: 0.1 Hz (if max speed < 100 Hz) or 0.25 Hz (if max speed ≥ 100 Hz).
  • The drive typically operates at a predetermined minimum speed unless disconnected. Refer to the user manual for zero-speed operation.
• Maximum Speed (F-04 Parameter):
  • Range: 30-240 Hz.
  • Step Size: 0.1 Hz (if max speed < 100 Hz) or 0.25 Hz (if max speed ≥ 100 Hz).
  • This sets the maximum output frequency.
• Current Limit (F-05 Parameter):
  • Controls limited motor output torque during run or acceleration.
  • Range: 10% to 150% of the rated controller current.
  • Step Size: 1.0%.
  • Setting too low may cause an overcurrent fault.
  • If output current exceeds the limit, motor speed is maintained/reduced, or deceleration time is extended.
