Parameter Regulation
The following parameters can be modified( See Group 19, Section 4 for Clark factory recommended settings)
1. ACC DELAY: Determines the acceleration ramp
2. RELEASE BRAKING: Controls the deceleration ramp when the travel request (accelerator) is released
The higher the setting, the more aggressive the braking.
3. INVERSION BRAKING: Controls the deceleration ramp when the direction is changed (FWD to REV or
REV to FWD) during travel.
The higher the setting, the more aggressive the braking.
4. PEDAL BRAKING: Determines the deceleration ramp when the travel request is (accelerator) released
and the brake pedal switch is closed.
The higher the setting, the more aggressive the braking.
5. SPEED LIMIT BRAKING: Deceleration ramp when the pedal position is changed but not completely released
6. BRAKE CUTBACK: Determines the deceleration ramp when the speed reduction input becomes active
and the motor slows down.
7. CURVE BRAKING:
(Do Not Change)
Determines the rate of the decelleration ramp in a curve as the steer wheel is
turned.
8. MAX SPEED FORWARD: Determines maximum speed in forward direction.
9. MAX SPEED BACKWARD: Determines maximum speed in reverse direction.
10. CURVE CUTBACK:
(CLARK Special)
Speed reduction when the truck in a turn. The parameter sets the speed set point
when the truck driving wheels are running in opposite direction (3 wheel truck,
steering angle greater than roughly 67°); or when the maximum steering angle is
reached (4 wheel truck, the internal wheel is stopped). In intermediate steering
angles, the speed set point will be within a range between the straight wheel speed
and the CURVE CUTBACK SPEED.
11. CURVE CUTBACK #1: Determines the speed of the inside wheel as the steering wheel is turned.
12. CUTBACK SPEED1:
(Not Used)
Speed reduction when cutback switch1 is active.
13. FREQUENCY CREEP:
(Do Not Change)
Minimum speed when the forward or reverse switch is closed, but the accelerator
is in a minimum position.
14. MAXIMUM CURRENT:
(Do Not Change)
Changes the maximum current of the controller
15. AUXILIARY TIME:
(Do Not Change)
Determines the time that the truck will hold on a ramp if the "stop on ramp" option
is ON.
16. SEAT MICRO DELAY: Used to set up the Delay value to open the seat switch.
17. ACC SMOOTH ACC SMOOTH controls the acceleration rate, when the speed request is between 0
Hz and the frequency setting defined by STOP SMOOTH. When the speed request
is above the STOP SMOOTH value, then the parameter ACCELERATION
DELAY controls the acceleration rate. Adjusting this level changes the time (in
seconds) required to accelerate the truck. The lower the acceleration level the
more aggressive the acceleration is.
18. INV SMOOTH INV SMOOTH is similar to ACC SMOTH but it controls the acceleration rate after
the truck is plugged to a complete stop and starts to accelerate in the opposite
direction.
19. STOP SMOOTH Sets the frequency point where ACC SMOOTH stops and ACCELERATION
DELAY starts.
20. IDLE TIME Sets the main line Contactor open time.
