Selection Description
Automatically switches between the modes Low Overload (LO) and High Overload (HO1).
For applications running at a non-varying or slowly varying load, where a limited overload capabil-
ity is required. This mode is typically used in applications with a variable torque load. The low over-
load profile allows the drive to run at 110% load for a minimum of 1 minute every 10 minutes. Typi-
cal applications where the low overload profile is used are:
• Fans
• Centrifugal pumps
• Blowers and aerators
• Screw compressors
