DESCRIPTION
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 the Sequencing
Delay expires and allow the vehicle to roll freely when the
interlock signal is removed. Typically, use this option only
when there is an operator/driver controlled mechanical or
hydraulic brake system.
Sets the rate (in seconds/Typical Max Speed) to slow down the
vehicle when the interlock is released at high vehicle speeds.
Larger values represent slower response.
See the Speed Mode/Response/Fine Turning/HS parameter.
Sets the rate (in seconds/Typical Max Speed) to slow down the
vehicle when the interlock is released at low vehicle speeds.
Larger values represent slower response.
See the Speed Mode/Response/Fine Turning/LS parameter.
Time after Zero_Speed_Threshold is reached during interlock
braking that the main contactor remains closed and the bridge
remains enabled, allowing position hold to settle.
Controls the maximum allowable duration of an interlock
braking event.
The timer starts as soon as the interlock signal is removed (i.e.,
the interlock switch is opened). If the time expires before the
vehicle has slowed below the Zero_Speed_Threshold the EM
brake will automatically engage.
This timeout allows parallel usage of regen braking and the EM
brake to reduce stopping distance. If the 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 the
EM_Brake_Type = 1 or 2.
Enables or Disables the interlock brake supervision function.
On = Supervision is enabled.
Off = Supervision is disabled.
Note, to comply with EN 13849, set this parameter to On (enabled).
The Interlock_Antitiedown_Time is the time after KSI voltage
is applied that interlock has to be held low (Off) to prove it is
not shorted.
To disable this functionality, set this Interlock Anti Tiedown
parameter to 0 ms.
