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.

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
