"Idle Vehicle Speed Limit"
The "Idle Vehicle Speed Limit" is the maximum vehicle speed for setting or maintaining a set engine rpm in the idle mode. In order to enter the idle mode, the engine rpm must be set by the set/resume switch while the cruise control on/off switch is in the ON position. If the vehicle speed signal exceeds this value, the engine will not maintain the set engine rpm.

Minimum Maximum Default
2 km/h (1 mph) 24 km/h (15 mph) 2 km/h (1 mph) "Idle RPM Limit"
The "Idle RPM Limit" is the maximum engine rpm in idle mode. The idle mode occurs if the engine rpm is set by using the cruise control on/off switch and the set/resume switch. Refer to "Idle Vehicle Speed Limit". The actual high limit of this parameter is determined by the programmed "Top Engine Limit". The lower limit is determined by the programmed "Low Idle Engine RPM".Programming this parameter to 600 rpm will prevent the engine from idling at a constant rpm above the programmed "Low Idle Engine RPM".

700 rpm TEL rpm TEL rpm "Idle/PTO RPM Ramp Rate"
The "Idle/PTO RPM Ramp Rate" determines the rate of increase or decrease of engine rpm. This parameter determines rates of increase or decrease in engine rpm for the following functions:
Accel
Decel
Resume idle
PTOThe parameter can be set to a value between 5 rpm and 1000 rpm in increments of one rpm.Note: This parameter affects both idle control and PTO control. The idle mode occurs if the engine rpm is set by using the cruise control on/off switch and the set/resume switch. The PTO mode occurs if the engine rpm is set by using the PTO on/off switch and the set/resume switch.

5 rpm/sec 1000 rpm/sec 50 rpm/sec "Idle/PTO Bump RPM"
The "Idle/PTO Bump RPM" determines the increment or the decrement in engine rpm when the "Accel" switch or the "Decel" switch is briefly toggled. The "Idle/PTO Bump RPM" also pertains to the dedicated PTO and to engine idle. If the "PTO Engine RPM Set Speed" has been set then the "Idle/PTO Bump RPM" pertains only to the engine speed control that is initiated with the cruise control on/off switch. When the "PTO Engine RPM Set Speed" has been programmed, the "Idle/PTO Bump RPM" does not pertain to the control of the engine rpm that is initiated by utilizing the PTO on/off circuit.

5 rpm 500 rpm 20 rpm "Fast Idle RPM 1"
"Fast Idle RPM 1" determines the fast idle engine rpm that is controlled by the fast idle enable switch. Actuating the fast idle switch will cause the engine speed to increase to the programmed value. This rpm can be overridden by the operator. To override the "Fast Idle RPM 1" setting, depress the accelerator pedal until the desired rpm is reached. Once the desired engine rpm is reached, depress the "Fast Idle Enable" switch. The ECM retains this value as the "Fast Idle RPM 1" parameter until the ECM
