Depth Autos Optimization on Cat NGH mini/micro machines

Optimize the Depth Autos performance

You may need to adjust the Autos Optimization settings when, for example, you work with a different type of material (such as sand, dirt, or gravel).

Adjusting the settings in the Autos Optimization screen may improve the performance of Autos. For example, if the boom is overshooting above the target design grade when you pull in the stick, you can decrease the Boom Raise speed.

Autos performance is dependent on the speed that you pull in the stick. Experiment with different speeds to find the optimum for your machine and combination of attachment and material. For example:

• A slower or faster speed may produce a better result.
• A smooth take off speed helps.
• Do not vary the speed while optimizing the sliders.

1. Select High Power mode and turn the throttle up to maximum revs.

2. Using Depth Autos, make a test pass in the material you are working, so that you can judge the current performance of Autos.

   1. Place the attachment on grade at near full reach.
   2. Engage Autos.
   3. Watch how quickly or slowly the attachment moves to the on‑grade position.

   NOTE – The behavior of Autos when the attachment is not loaded with the same material you will work with does not provide enough information to adjust the values in the Autos Optimization screen. Always use this information in conjunction with the results of a test pass.

3. To make any changes, in the Autos Optimization screen, select the appropriate type from the Optimize drop‑down list.

4. Move the slider(s) to increase or decrease the values for the following:

   TIP – The apex is where the boom changes from raising to lowering during a pass.

   

   1

   Full reach to apex

   2

   Apex

   3

   Apex to fully crowded

   Type	Option	Description
   Attack Angle	Attack Angle	If required, move the Attack Angle slider to change the angle of the bottom of the attachment to the design surface. Zero is parallel, a negative value will lower the back of the attachment and a positive value will raise the back of the attachment.
   Rake	Rake In Before Apex	If the finished surface is below grade when you perform a Rake In pass from full reach to the apex, increase this value.
   	Rake In After Apex	If the finished surface is below grade when you perform a Rake In pass from apex to fully crowded, increase this value.
   	Rake Out Before Apex	If the finished surface is below grade when you perform a Rake Out pass from fully crowded to the apex, increase this value.
   	Rake Out After Apex	If the finished surface is below grade when you perform a Rake Out pass from the apex to full reach, increase this value.
   Flat Attachment In	Flat Attachment In(Boom) Before Apex	If the finished surface is below grade when you perform a Flat Attachment In pass from full reach to the apex, increase this value. This will control the boom raise and lower commands.
   	Flat Attachment In(Boom) After Apex	If the finished surface is below grade when you perform a Flat Attachment In pass from the apex to fully crowded, increase this value. This will control the boom raise and lower commands.
   	Flat Attachment In (Attachment) Before Apex	If the attachment changes angle too slowly and does not keep flat on grade when you perform a Flat Attachment In pass from full reach to the apex, increase this value.
   	Flat Attachment In (Attachment) After Apex	If the attachment changes angle too slowly and does not keep flat on grade when you perform a Flat Attachment In pass from the apex to fully crowded, increase this value.
   Flat Attachment Out	Flat Attachment Out (Boom) Before Apex	If the finished surface is below grade when you perform a Flat Attachment Out pass from fully crowded to the apex, increase this value. This will control the boom raise and lower commands.
   	Flat Attachment Out (Boom) After Apex	If the attachment changes angle too slowly and does not keep flat on grade when you perform a Flat Attachment Out pass from the apex to full reach, increase this value. This will control the boom raise and lower commands.
   	Flat Attachment Out (Attachment) Before Apex	If the attachment changes angle too slowly and does not keep flat on grade when you perform a Flat Attachment Out pass from fully crowded to the apex, increase this value.
   	Flat Attachment Out (Attachment) After Apex	If the attachment changes angle too slowly and does not keep flat on grade when you perform a Flat Attachment Out pass from the apex to full reach, increase this value.
   Boom	Raise Speed	Looking at the surface from full reach to the apex, use Boom Raise Speed to make the attachment cut to grade. If the finished surface is consistently below grade, increase this value.
   	Raise Response	If the boom is slow to rise, then increase this value.
   	Lower Speed	Looking at the surface from the apex to fully crowded, use Boom Lower Speed to make the attachment cut to grade. If the finished surface is consistently above grade, increase this value.
   	Lower Response	If the boom is slow to lower, then increase this value.
   	Take Off Speed	If the boom is not driving to grade within the first 0.5 m/1.5 ft after the stick is pulled, increase this value. Decreasing this value may reduce oscillations at the very beginning of the pass.
   Joystick	Joystick Response Speed	If both the boom and attachment are slow to respond to stick movement, increase this value. Decreasing this value may reduce oscillations at the very beginning of the pass and oscillations observed when the stick movement is slow.
   Attachment	Dump Speed	If the attachment is slow to dump for the full duration of the pass, increase this value.
   	Dump Response	If the attachment is slow to dump, then increase this value.
   	Curl Speed	If the attachment is slow to curl for the full duration of the pass, increase this value.
   	Curl Response	If the attachment is slow to curl, then increase this value.

5. Tap Apply.

6. Make another test pass and compare the results. Repeat the process, if necessary, until you get the results you desire.

   You may need to enlist the help of your technician for further fine tuning and a precise check of the machine measure‑up.

Presets

Presets allow you to save Autos Optimization settings so that you can restore them later. This is useful when there is a change in application or material.

Select and Apply a Preset

You can select and apply the active preset via the Autos Setup or Autos Optimization screen. You can access these screens via the Work Settings menu. There is always at least one preset stored which is the Default preset set by your technician in the Web Interface. This cannot be edited or deleted.
