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
OptionBits3 [Bit 7]
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
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.
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.
Interlock Brake Timeout
0–8.0 sec
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
before the vehicle has slowed below the Set_Speed_Threshold, the EM brake
will engage automatically.
This parameter can be used to allow 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 46).
