Introduction
This manual documents the Antistall plug-in.
The Antistall plug-in receives engine rpm inputs. The Antistall plug-in outputs values
between 100.00% and a lower, user-set value.
An application typically multiplies its speed commands by the Antistall plug-in output.
• When a high load causes engine rpm to drop, the Antistall output begins dropping
from 100.00% towards a lower user-set final value. The drop in output is proportional
to the drop in engine rpm.
Multiplication of speed commands by less than 100.00% scales down the speed
command values.
The reduction in speed command values lowers the engine load and helps keep the
engine from stalling.
• When engine rpm returns to normal, the Antistall output returns to 100.00%.
Multiplication of the speed commands by 100.00% leaves the speed command values
unchanged.
T In applications that use the Antistall plug-in and receive CAN engine speed messages,
set the application’s ExecTimeOut value to match the repetition rate of the CAN engine
speed message.
(In applications that receive CAN engine speed messages, the engine speed update time
is limited to the repetition rate of the CAN engine speed message.)
The responsiveness of the notch filter decreases if the Antistall plug-in updates faster
than engine speed. This reduces the effectiveness of the Antistall plug-in.

Multiply by speed commands
The Antistall plug-in outputs an AStall% value based on the difference between the
desired engine rpm and the actual engine rpm.
Typically, an application multiplies the AStall% output by its speed commands.
When the engine rpm:
• Is in the desired range, the AStall% output is 10000 (100.00%).
Multiplying by100.00% does not scale down the speed commands.
• Drops out of its desired range because of a heavy load, the AStall% output becomes
less than 10000 (100.00%).
Multiplying by less than 100.00% scales down the speed commands.
Antistall Plug-in Page
Callout Item Description
1 AStall_Params
page
Contains EE components whose signals define the operation of the Antistall plug-in.
2 Antistall
page
Receives a Desired_RPM and an actual Engine RPM input.
When a heavy load causes actual engine rpm to drop, the Astall% output starts dropping below 10000 (100.00%).
The greater the decrease in actual rpm, the greater the drop in the Astall% output.
Multiplying the AStall% output by the speed commands scales down the speed commands.
For example, when the AStall% output is:
– 10000 (100.00%), multiplication does not scale down the speed commands.
– 7000 (70.00%), multiplication scales down the speed commands by 30.00%.

The Astall_Params page contains non-volatile memory (EE) components whose values
define the operation of the Antistall plug-in.
Astall_Params Page
Callout Item Description
1 EE_AStall_Enable
EE value
Outputs the Enable signal.
T = Enable the Antistall plug-in. A decrease in engine rpm can apply antistall.
F = Disable the Antistall plug-in. The plug-in’s Astall% output stays at a steady 10000 (100.00%)
2 EE_AStall_Amin_Pct2
EE value
Outputs the Amin signal.
This signal sets the minimum Astall% output. (The smaller the output, the greater the antistall
effect.)
As engine rpm drops under load, the Astall% output decreases from 10000 (100.00%) until it
reaches the Amin value.
Multiplying propel commands by the Astall% output scales down speed commands and prevents
heavy loads from stalling the engine.
Range: 0–10000 (10000 = 100.00%)
3 EE_AStall_Astart_RPM
EE value
Outputs the Astart signal.
This signal sets the engine rpm at which the Astall% output starts decreasing from 10000 (100.00%)
towards the Amin value.
The Astart signal must be less than the HiIdleRPM signal.
Range: 0–8322 (1 = 1 rpm)
4 EE_AStall_Damping_dB
EE value
Outputs the Dampting_db signal.
Sets the damping applied by the lead-lag filter.
Range: -6–-18 (1 = 1 dB)

Callout Item Description
5 EE_AStall_MaxRecvyEr
EE value
Outputs the MaxRecvyEr signal.
This signal sets the rate at which the Astall% output rises once decreasing load allows the engine
rpm to rise above the Astart value.
The recovery rate is based on the rise in engine rpm. The larger the MaxRecvryErr, the faster the rise
in the Astall% output.
Range: 0–8032 (Typical setting: 20–25)
6 EE_AStall_PBand
EE value
Outputs the PBand signal.
This signal sets the rpm range over which the Astall% output changes between 10000 (100.00%)
and 0 (0%).
The Amin value, which sets the minimum Astall% output, typically keeps the output from ever
reaching a 0 (0%) value.
Range: 0–8032 (1 = 1 rpm)
7 EE_AStall_Tx
EE value
Outputs the Tx signal.
This signal sets the pseudo-time constant for the lead filter used in the Antistall plug-in.
The lead and lag filters smooth the antistall response.
Range: 0–4096
8 EE_AStall_Ty
EE value
Outputs the Ty signal.
This signal sets the pseudo-time constant for the lag filter used in the Antistall plug-in.
The lead and lag filters smooth the antistall response.
Range: 0–4096
9 EE_AStall_High_Throttle_RPM
EE value
Outputs the HiIdleRPM signal.
This signal sets the engine’s expected high idle rpm under no load.
The HiIdleRPM signal must be greater than the Astart signal.
If the Desired_RPM and HiIdleRPM values are different, the percentage difference between these
two values is applied to proportionally change the Astart antistall starting point and the PBand
width.
Range: 0–8032 (1 = 1 rpm)

• The HiIdleRPM value is the engine’s normal, high idle rpm under no-load.
• The Desired_rpm is the operator-set rpm.
In this example, the HiIdleRPM and Desired_RPM values are the same.
• The Astart value sets the engine rpm at which the Astall% output starts decreasing
from 10000 (100.00%).
Multiplying propel commands by Astall% output scales down the speed commands
to prevent heavy loads from stalling the engine.
• The PBand value sets the rpm range over which the Astall% output changes
between 10000 (100.00%) and 0 (0%).
• The Amin value sets the lower limit of the Astall% output. When the engine rpm
reaches or drops below this limit, the output stays steady.

HiIdleRPM > Desired_RPM
• The HiIdleRPM value is the engine’s normal, high idle rpm under no-load.
• The Desired_rpm is the operator-set rpm.
In this example, the HiIdleRPM and Desired_RPM values are the different.
When the Desired_RPM and HiIdleRPM values are different, the plug-in applies the
percentage difference between these two values to proportionally change both the
Astart start of antistall and the PBand width.
• The antistall plots in Example 1 and Example 2 have the same values, except that the
Desired_RPM value in Example 2 is 1900 rpm, instead of 2100 rpm.
• The percentage difference between the Desired_RPM and HiIdleRPM values is 90.4%
(1900 ÷ 2100 = 90.4).
• The plug-in applies the 90.4% percentage difference between the Desired_RPM and
HiIdleRPM signals to proportionally reduce the:
− Astart value from 1900 rpm to 1717 rpm (1900 x 0.904 = 1717).
− Pband value from 350 rpm to 316 rpm (350 x 0.904 = 316).
