6. The drive will not accelerate to maximum speed -- No fault is displayed.
The maximum allowable drive output frequency will be determined by the
lowest programmed value of any of the following parameters:
•
Parameter 3 Frequency Range
•
Parameter 15 Maximum Frequency
•
Parameter 51 Upper Frequency Clamp
•
Parameter 53 Bias Frequency -- If Parameter 53 is Higher Than
Parameter 54
•
Parameter 54 Gain Frequency -- If Parameter 54 is Higher Than
Parameter 53
Is Parameters 3 Frequency Range and/or 15 Maximum Frequency set high
enough to allow the drive to accelerate to maximum speed?
Reset Parameters 3 and/or 15.
Yes
No
No
Is Parameter 51 Upper Frequency Clamp set to a value lower than the
required maximum frequency?
Reset Parameter 51 to maximum frequency.
Yes
No
Contact your nearest AĆB representative for application assistance.
No
Yes
Are Parameters 42Ć45 programmed to exclude maximum frequency?
Reprogram Parameters 42, 43 and/or 44 to a value below the maximum
frequency. Reprogram Parameter 45 to a bandwidth that will not include the
maximum frequency value.
Yes
Is this an inverse speed follower application?
To program the drive for an inverse speed follower application, set Parameter
53 to the maximum frequency required and Parameter 54 to the minimum
frequency required.
Yes
Yes
Is Parameter 53 Bias Frequency set to a higher value than Parameter 54 Gain
Frequency (standard setting for inverse speed follower applications)?
If an inverse speed follower is required, reprogram Parameter 53 to maximum
frequency. If an inverse follower is not required, reprogram Parameters 53
and 54 as required.
No
Yes
Is Parameter 53 Bias Frequency set to a lower value than the required
maximum frequency?
Reset Parameter 53 to maximum Frequency.
