C5-05: ASR Limit
Sets
the ASR output limit as a percentage
of the maximum output frequency (E1-04). If the motor slip is high, the setting
might need to be increased to provide proper slip compensation. Use the ASR output monitor U6-04 to determine if ASR
is working at the limit and make settings if necessary. If ASR is operating at the ASR limit, check the pulse signal and the
pulse input settings prior to changes in C5-05.

C6-01: Drive Duty Selection
The drive has two different duty modes from which to select based on the load characteristics. The drive rated current,
overload capacity, and carrier frequency will change depending upon the duty mode selection. Use parameter C6-01 to
select Heavy Duty (HD) or Normal Duty (ND) for the application. The default setting is ND. Refer to Heavy Duty and
Normal Duty Ratings on page 318 for details about the rated current.

Application
Use Heavy Duty Rating for applications requiring a high
overload tolerance with constant load torque. Such
applications include extruders and conveyors.
Use Normal Duty Rating for applications in which the
torque requirements drop along with the speed. Examples
include fans or pumps where a high overload tolerance is
not required.
