1 – SPEED MODE PUMP PARAMETERS
ALLOWABLE
PARAMETER RANGE DESCRIPTION
Pump Enable On / Off This parameter should be programmed On to operate a pump motor
AC_Pump_Enable_SpdM On / Off rather than a vehicle drive motor. Speed controller responsiveness
AC_Pump_Enable_SpdM_Bit0 [Bit 0] and stability are enhanced.
0x3896 0x00
Regen Lower Enable On / Off This parameter works together with Pump Enable as follows.
Regen_Lower_Enable_SpdM On / Off When Pump Enable = On and Regen Lower Enable = On, the pump
Regen_Lower_Enable_SpdM_Bit0
[Bit 0] motor can turn in both the forward and the reverse direction. In this case,
0x3877 0x00 the pump can be used as the Lower function (reverse).
When Pump Enable = On and Regen Lower Enable = Off, the pump
motor can turn only in the forward direction. In this case, a hydraulic valve
is typically used for the Lower function.
When Pump Enable = Off, the Regen Lower Enable parameter
has no effect on the control system.
1 – SPEED MODE POSITION HOLD MENU, cont’d
ALLOWABLE
PARAMETER RANGE DESCRIPTION
Set Speed Settling Time 0 – 5000 ms This parameter appears twice in the menu structure. For description,
Set_Speed_Settling_Time 0 – 156 see EM Brake Control menu, page 48.
0x3024 0x00
Set Speed Threshold 5 – 100 rpm This parameter appears twice in the menu structure. For description,
Set_Speed_Threshold 5 – 100 see EM Brake Control menu, page 48.
0x306F 0x00
Entry Rate 5 – 100 % When the vehicle transitions from forward speed to reverse speed
Entry_Rate_Position_Hold 50 – 1000 or from reverse speed to forward speed (for example, when coming to
0x383B 0x00 a stop going up a steep ramp), Position Hold is automatically entered
immediatelyatzerospeed—regardlessofthisparameter.
This parameter applies when the vehicle needs to be brought to
a stop without the assistance of gravity (for example, when moving
forwarddownaramp).Thisratedetermineshowquicklyzerospeed
isattainedaftertherampedspeedrequestreacheszero.Settingthis
parameter too high will make the stop seem very abrupt, and may even
cause the vehicle to roll back slightly. When the parameter is set lower,
the vehicle take longer to come to a stop and enter Position Hold mode.
Exit Rollback Reduction
0 – 100 % This function is applicable only when the Torque Preload function has
Exit_Rollback_Reduction 0 – 2048 been disabled (see EM Brake Control menu), or its timer has expired.
0x3844 0x00 It introduces a proportional feedforward term into the speed controller
based on the position signal. For example, suppose the vehicle is on a
ramp and a forward throttle request is given such that the vehicle rolls
back slightly before climbing the ramp (again, assuming the torque pre-
load function is inactive). As the vehicle rolls back a feedforward torque
term proportional to the rollback position will be added to the torque
request until forward speed is sensed.
