and electromagnetic brake
contactor coils, using the
interlock and dropout delay
functions.
2 — INSTALLATION & WIRING: Contactor Drivers
Electromagnetic Brake Driver
e electromagnetic brake driver (Pin 20) pulls low when the controller receives
a throttle request or detects that the vehicle is still in braking mode. If desired,
the Brake Delay parameter can be set to allow the brake to remain disengaged
for up to 5 seconds after braking to neutral has been completed. If the delay
function is used, the brake driver and the coil return (Pin 9) must both be
wired to KSI rather than the interlock input. is alternative wiring is shown
in Figure 12.
If the rottle Braking parameter has been set to zero, the brake delay
time begins when the throttle is returned to neutral and the PWM output de-
celerates to zero. e output will be pulse-width-modulated at the coil holding
voltage along with the main, auxiliary, and reverse signal contactor drivers, if
the holding voltage parameter is set to less than 100%.
