• Increase the gain and/or reduce the integral time if the response is slow at maximum output frequency.
• Reduce the gain and/or increase the integral time when vibrations occur at the maximum output frequency.
• When adjusting ASR always first adjust the P gain, then adjust the integral time.

C5-05: ASR Output 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 Mode Selection
The drive has two different duty modes from which to select based on the load characteristics. The drive rated current,
overload capacity, carrier frequency, and maximum output frequency will change depending upon the duty mode selection.
Use parameter C6-01 (Duty Cycle) 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 288
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.
