Description
Sets the amount of offset of the output of the PI controller. Set as a% of
fmax.
The PI Offset Adjustment parameter has two different uses. Parameter
b5-07 serves different functions depending on whether it is used on a
standard PI loop or a Differential PI loop.
1: Parameter b5-07 causes an offset to be applied to the output of the PI
function in a non-Differential PI loop. Every time the PI output is
updated, the offset is summed with the PI output. This can be used to
artificially kick-start a slow starting PI loop.
2: If the Drive is configured for Differential PI Regulation (H3-09=16),
then the PI Offset is the targeted maintained differential between the
signal measured on analog input A1 and the signal measured on analog
input A2.
Sets the amount of time for a filter on the output of the PI controller.
Determines whether the PI controller will be direct or reverse acting.
0: Normal Output (direct acting)
1: Reverse Output (reverse acting)
Sets the output gain of the PI controller.
0: Disabled
1: Alarm
2: Fault
Sets the PI feedback loss detection level as a percentage of maximum
frequency (E1-04).
Sets the PI feedback loss detection delay time in terms of seconds.
Applies an accel/decel time to the PI setpoint reference.
Energy Saving

0: Disabled
1: Enabled
Used to fine-tune the energy savings function.
Accel / Decel
Sets the time to accelerate from zero to maximum frequency.
Sets the time to decelerate from maximum frequency to zero.
Sets the time to accelerate from zero to maximum frequency when
selected via a multi-function input.
Sets the time to decelerate from maximum frequency to zero when
selected via a multi-function input.
Sets the time to accelerate from zero to maximum frequency when
activated by P3-12. Used for system response stabilization.
Sets the time to decelerate from maximum frequency to zero when
activated by P3-12. Used for system response stabilization.
Sets the time to decelerate from maximum frequency to zero for the
"Fast Stop" function.
