3 — PROGRAMMABLE PARAMETERS: Interlock Braking Parameters
INTERLOCK BRAKING MENU
ALLOWABLE
PARAMETER RANGE DESCRIPTION
Enable On / Off Determines whether the interlock braking function is active.
Interlock_Brake_Enable On / Off On = The controller will attempt to bring the vehicle to a stop using regen

braking when the interlock signal is removed.
0x306C 0x00 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
0.1 – 30.0 Sets the rate (in seconds) that is used to slow down the vehicle when the
Interlock_Brake_Decel_ 100 – 30000 interlock is released at high vehicle speeds. Larger values represent slower
Rate_HS response.
0x309F 0x00
Decel Rate LS 0.1 – 30.0 Sets the rate (in seconds) that is used to slow down the vehicle when the
Interlock_Brake_Decel_ 100 – 30000 interlock is released at low vehicle speeds. Larger values represent slower
Rate_LS response.
0x309E 0x00
Interlock Brake Timeout 0.0 – 8.0 s Controls the maximum allowable duration of an interlock braking event.
Interlock_Brake_Timeout 0 – 1000 The timer starts as soon as the interlock signal is removed. If the time expires
0x309C 0x00 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
(see page 48).
