Drive Control System— Drive Controller Pedal Calibration Parameters Drive Controller Pedal Calibration Parameters
NOTE: Adjust this value only in increments of 100 and then test. Extreme changes to this value will reduce the effective control range of the drive pedal.
Poor or no control response will result if the pedals are out of calibration.The PLUS+1 module must be recalibrated whenever:
2. This field indicates the maximum expected drive pedal fully depressed or full travel position.
• The articulated loader speed control or brake/inch pedal mechanical components are removed for service or replacement.
NOTE: Adjust this value only in increments of 100 and then test. Extreme changes to this value will reduce the effective control range of the drive pedal.
• The electronic pedal sensor is removed for service or replacement.
3. These fields indicate the tolerance modifiers for the expected minimum and maximum values (1 and 2). Numbers in these fields set a range above and below minimum and maximum values (1 and 2) that will be accepted during the calibration process.
• The PLUS+1 module is replaced.
Driving Pedal Parameter Screen
NOTE: Adjust these values only in increments of 10, and then test. Extreme changes to this value will reduce the effective control range of the drive pedal.
The “Driving” screen is used to change minimum and maximum values used in pedal calibration. NOTE: Minimum/maximum pedal calibration values needs to be changed only if pedal calibration is not possible because actual pedal travel falls outside the indicated minimum and maximum position values. Values on this screen are expressed in digits instead of volts. Actual pedal position can be determined in real-time using the pedal position input field on the “Electrical Inputs/Outputs” monitoring screen (item 3, page 176). To convert pedal mV values to digits, multiply mV by 2 (example: 500 mV X 2 = 1000 digits. To access the “Driving” screen, select “Diagnostic Navigator”: “Parameter Functions > Inputs > Driving.”
NOTE: Changes made in this screen do not take effect until the download button is clicked. This button is located near the top of the screen.
Pump Profiling Screen/Drive “Creep” Adjustment The “Pump Profiling Automotive” screens are used to adjust machine “creep”. “Creep” occurs when the machine moves if the drive is shifted to forward or reverse while engine speed is below 1200 RPM. There are two “Pump Profiling Automotive” screens: one for low- (Mode 4), and one for high-speed (Mode 2) travel modes.
