Selection Description
For applications which require higher short-term overload and constant torque operations. Typical
applications work with continuous motion. With high overload mode HO1, the drive can run with a
load of up to 160% for 1 minute every 10 minutes, with a breakaway torque of up to 200%, depend-
ing on size. Typical applications where high overload HO1 is used are:
• Conveyors
• Centrifuges
• Decanters
• Piston compressors
• Piston pumps
• Mixers
• Stirrers
• Escalators
• Extruders (continuous running)
Used when the application has intermittent or continuous periodic duty. The resulting cyclic load
requires more considerations on the use of the drive to ensure necessary performance and lifetime.
Increased short-term starting torque is often also required. To benefit from the increased dynamic
performance and not compromising lifetime, the output current is downrated by one motor size
compared to HO1. With the high overload profile with increased duty, the drive can run with up to
160% load for 1 minute every 5 minutes, with a breakaway torque of up to 200%, depending on the
current rating. Typical applications where the high overload profile with increased duty is used are:
• Extruders
• Continuously accelerating conveyors
• Lifts and hoists
• Cranes
• Positioning applications
• Dosing pumps
