Rockwell Automation Allen-Bradley PowerFlex 700S Programming Manual

Chapter 2 Programming and Parameters
132 Inert Adapt Sel
Configures the Inertia Adaptation Algorithm (IAA Function).
• Bit 0 “Inrtia Adapt” when set to 1 (on), the Inertia Adaptation function will effect enhanced stability, higher bandwidths and dynamic stiffness. Useful when systems with a gear-box becomes
disconnected from the load. Also used with motors that have very little inertia that otherwise lack dynamic stiffness, even at high bandwidths.
• Bit 1 “Load Est” when set to 1 (on), the Load Estimate option removes or greatly reduces load disturbances and gives quicker system response.
• Bit 2 “First Diff” selects the first difference feedback for Inertia Adaptation.
Notes: When setting both Bit 0 & 1, stability is enhanced and load disturbances are removed. Bit 2 “First Diff” was added for firmware version 3.001.
133 Inert Adapt BW
This parameter sets the bandwidth of the Inertia Adaptation function when the IAA function is selected
(Par
132 [Inert Adapt Sel], bit 0 = 1). Typical IAA bandwidths range from 70 to 150 rad/sec with 100 rad/sec
nominal best.
If the Load Estimate function is selected (Par
132 [Inert Adapt Sel], bit 0 = 1), then this parameter sets the natural
frequency of a filter in rad/sec. Typical values range from 10 to 150 rad/sec with higher values being more
responsive to disturbances but with increased system noise. There is no nominal best value, but 40 rad/sec is a
suggested starting point. This adjustment may not function well in 'sloppy' geared systems.
If both Inertia Adaptation and Load Estimate functions are active, use a bandwidth setting of 100 rad/sec.

134 Inert Adapt Gain
This parameter sets a multiplier of system inertia when the Inertia Adaptation function is selected
(Par 132 [Inert Adapt Sel], bit 0 = 1). Higher values may cause high frequency ringing, while smaller values may
cause fundamental load instability. A typical value is 0.5 This parameter has no affect on the Load Estimate
function.

Sets a frequency at which the drive will not operate. [Skip Speed 1 - 3] and Par 139 [Skip Speed Band] must not

139 Skip Speed Band
Determines the bandwidth around a skip frequency. [Skip Speed Band] is split, applying 1/2 above and 1/2 below
the actual skip frequency. The same bandwidth applies to all skip frequencies.

146 FW TaskTime Sel
Sets the scan times for the drive firmware. Changing the firmware scan times will affect drive performance. Faster
scan times may allow for higher bandwidth of the internal regulators. To achieve faster scan times some functions
may need to be disabled. Only the most demanding application may benefit from faster scan times. Typically,
adjusting this parameter is not needed, it is recommended you consult the factory before changing.

147 FW Functions En
Allows specific firmware functions to be disabled. When a bit is false, the associated function is disabled and all related parameters will be hidden. When a bit is true, the associated function is
enabled and all related parameters will be displayed.
Notes: Bits 18, 20, & 21 were changed to “Reserved” for firmware version 2.004. Bit 19 “MotinPlanner” and 24 “PhaseLockLp” were added for firmware version 3.001.
