SETTING VARIABlE SPEED

Variable speed parameters activate throttle or fuel control relative to the variable speed input signal.  This requires a single remote 

speed adjustment potentiometer is installed to adjust the engine speed continuously over a specific speed range.  At the Variable 

Speed 

 Voltage Speed Input Mode:

• 

Voltage Input: (Select 0 - 5 V / Resistive) Voltage to 5.0 V, above 5.0 V the variable speed function is clamped at 100 %, rpm 

response to voltage is linear.

• 

Current Input: (Select 4 - 20 mA) Speed Minimum sets the low speed at 4 mA.  Speed Maximum sets the high speed at 20 mA. If 

the input current drops below 4 mA, variable speed is clamped at 0 %. If the input current level exceeds 20 mA, variable speed is 

clamped at 100 %. The rpm response to current is linear.

  % rpm

Variable speed (rpm) based on current input or voltage expected results are shown here. Note the following:
• 

If the Minimum Speed setting is higher than Maximum Speed, increasing the speed input signal / potentiometer position will de

-

crease rpm.

• 

Minimum Speed and Maximum Speed setting ranges are 150 to 6000 

rpm with default value of 1500 rpm.

• 

Gain, Stability, and Deadtime values may need adjustment after engine load is applied. 

• 

Normally adjustments made at no load achieve satisfactory performance.  

• 

If further performance improvements are required, see
