INTERLOCK BRAKING MENU
PARAMETER ALLOWABLE RANGE DESCRIPTION

On / Off
On / Off
Determines whether the interlock braking function is active.
On = The controller will attempt to bring the vehicle to a stop using regen
braking when the interlock signal is removed.
Off = The controller will disable the bridge after Sequencing Delay expires
and allow the vehicle to roll freely when the interlock signal is
removed. This option is typically used only when there is a user
controlled mechanical or hydraulic brake system.
Decel Rate HS
Interlock_Brake_Decel_ Rate_HS
0x309F 0x00
0.1 – 30.0 s
100 – 30000
Sets the rate (in seconds) that is used to slow down the vehicle when the
interlock is released at high vehicle speeds (speeds > HS setting). Larger
values represent slower response.
Decel Rate LS
Interlock_Brake_Decel_ Rate_LS
0x309E 0x00
0.1 – 30.0 s
100 – 30000
Sets the rate (in seconds) that is used to slow down the vehicle when the
interlock is released at low vehicle speeds (speeds < LS setting). Larger
values represent slower response.
Interlock Brake Timeout
Interlock_Brake_Timeout
0x309C 0x00
0.0 – 8.0 s
0 – 1000
Controls the maximum allowable duration of an interlock braking event. The
timer starts as soon as the interlock signal is removed. If the time expires
before the vehicle has slowed below the Set_Speed_Threshold, the EM
brake will engage automatically.
This timeout allows parallel usage of regen braking and the EM brake to
reduce stopping distance. If Interlock Brake Timeout expires and the motor
is still moving, regen braking will continue to retard vehicle motion in
conjunction with the EM brake.
NOTE: This parameter is only applicable when EM_Brake_Type = 1 or 2
(page 49).
