Specifications
See Table 1 or Table 3.
11. Using the data increase/decrease key, change the function setting to the new setting. Pressing the
(+) side of the key will increase the parameter value. Pressing the (−) side of the key will decrease
the parameter setting.
WARNING
Program changes affect lift truck performance and operation. If function settings are changed,
make sure all operators of the lift truck know that the truck has been changed and may
operate differently.
12. Press the left arrow on the menu navigation key to return to the PARAMETERS menu.
13. Repeat Step 8 through Step 12, as required, until all of the functions are set to the desired value.
NOTE: Any unwanted change made to any of the function values can be undone using the RESET ALL
SETTINGS from the FUNCTIONS menu as long as the programmer has not been unplugged or the
key switch has not been turned to the OFF position (power disconnected).
14. Turn the key switch to the OFF position.
15. Disconnect the battery connector.
WARNING
The capacitor in the traction motor controller can hold an electrical charge after the battery is
disconnected. To prevent electrical shock and injury, discharge the capacitor before inspecting
or repairing any component. Wear safety glasses. Make certain the battery has been
disconnected. Discharge the capacitors using the recommended procedures and never by any
other method.
16. Discharge the capacitors in the traction motor controller by connecting a 200-ohm, 2-watt resistor
across the controller’s B+ and B− terminals using two insulated jumper wires.
17. Disconnect the programmer handset from the controller.
18. Install the drive unit compartment covers.
19. Reconnect the battery.
Parameters
ADJUSTING PARAMETERS
NOTE: M2 parameters do not apply to MPW060E, MPW065E, and MPW080E.
Top Speed
The M1 Max Speed parameter adjusts the top speed of the truck when in Walk mode. The M2 Max
Speed parameter adjusts the top speed of the truck when in Rabbit mode. Decrease this setting to
reduce the top speed and increase this setting to raise the top speed of the truck. The M1 adjustable
range is from 25% to 48%. The M2 adjustable range is from 25% to 100%.
Acceleration
The M1 Accel Rate and the M2 Accel Rate parameters adjust the acceleration of the truck. This is true
in both Walk and Rabbit modes or M1 and M2. Decrease this setting to quicken the acceleration of the
truck, and increase this setting to soften the acceleration of the truck. The adjustable range is from 0.1
to 3.0 sec.
Neutral Braking
The M1 Decel Rate and the M2 Decel Rate parameters adjust the response of the truck when
returning to neutral. Decrease this setting to strengthen the neutral braking of the truck, and increase
this setting to weaken the neutral braking of the truck. The adjustable range is from 0.1 to 10.0 sec.
Plug Braking
The M1 Brake C/L and the M2 Brake C/L parameters adjust the response of the truck when plug
braking. Decrease this setting to soften the plug braking of the truck, and increase this setting to
strengthen the plug braking of the truck. The adjustable range is from 75 amps to 350 amps.
Coast Braking (MPE060-E/MPE080-E Only)
The Coast C/L parameter adjusts the response of the truck when releasing the quick pick switch.
Decrease this setting to soften the coast braking of the truck, and increase this setting to strengthen
the coast braking of the truck. The adjustable range is from 25 amps to 350 amps.
Empty Volts
The BDI Empty Volts parameter sets the voltage considered to be a 0% state of charge. If using
sealed, maintenance-free batteries, set this parameter to 190. Otherwise, leave at factory setting.
Battery Discharge Indicator (BDI)/Hourmeter
The 8-character LCD on the optional BDI/Hourmeter displays provides a continuous sequence of
hourmeter, battery state of charge, and fault messages. See Figure 21. Fault messages are displayed
using the same codes that are flashed by the controller’s LED. For example, code "3,2" (Main
Contactor Welded) appears as CODE 32.
