11-48 Parameters
156 Autotune Status
Autotune Status provides information about the auto-tune
procedure.
The bits are defined as follows:

Factory default not applicable
Minimum value 00000000.00000000
Maximum value 00110000.11111111

Refer to Chapter 13, Understanding the Auto-tuning Procedure,
for more information.
Bit Description
0 Executing
Auto-tune is currently executing.
1 Complete
Auto-tune has completed.
2 Fail
An error was encountered.
3 Abort
Auto-tune was aborted by a stop
command.
Bit Description
4 Flux Active
The motor has flux.
5 Not Ready
The drive is not ready to start
auto-tune.
6 Not Zero Spd
The drive cannot start auto-tune.
7 Running
The motor is running.
Bit Description
8 – 11 Reserved
Leave 0.
12 Timeout
Auto-tune timed out. The inertia
test failed to accelerate the load.
13 No Trq Lim
The inertia test failed to reach the
torque limit.
14 – 15 Reserved
Leave 0.
157 Total Inertia
Total Inertia represents the time, in seconds, for a motor coupled
to a load to accelerate from zero to base speed, at rated motor
torque. The drive calculates Total Inertia during the auto-tune
procedure when the auto-tune routines are run.
The 1336 IMPACT drive uses Total Inertia and Spd Desired BW
(parameter 161) to calculate the speed loop gains
(parameters 158 and 159). If you cannot run the auto-tune inertia
test, you should estimate Total Inertia and set it manually.

Minimum value 0.01 second
Maximum value 655.00 second

158 Ki Speed Loop
Use Ki Speed Loop to control the integral error gain of the speed
regulator.
The 1336 IMPACT drive automatically adjusts Ki Speed Loop
when you enter a non-zero value for Spd Desired BW
(parameter 161). Normally, you should adjust Spd Desired BW
and let the drive calculate the gains. If manual adjustment is
needed (for example, if the inertia cannot be determined), the
drive sets Spd Desired BW to zero for you when this gain is
changed.
Parameter number 158

Parameter type linkable destination

Factory default 8.0
Minimum value 0.0
Maximum value 4095.9
Conversion 8 = 1.0
159 Kp Speed Loop
Use Kp Speed Loop to control the proportional error gain of the
speed regulator.
The 1336 IMPACT drive automatically adjusts Kp Speed Loop
when you enter a non-zero value for Spd Desired BW
(parameter 161). Normally, you should adjust Spd Desired BW
and let the drive calculate the gains. If manual gain adjustment is
needed (for example, if the inertia cannot be determined), the
drive sets Spd Desired BW to zero for you when this gain is
changed.
Parameter number 159
