controller’s four delay
parameters (sequencing,
interlock brake, main
contactor open, and aux
delays). This figure assumes
the standard wiring
configuration, which
includes an EM brake.
For descriptions of the
sequencing delay and main
contactor open delay, see
pages 42 and 40.
Interlock Brake Delay
(0.0 – 8.0 s)
The EM brake engages unless it already engaged
at the completion of interlock braking.
Interlock braking from motor
(applied until motor speed approx. zero)
The EM brake engages unless it already engaged
at the expiration of Intk Brake Delay.
*
The neutral state is reached when, during normal operation,
the throttle is in neutral, both direction switches are open,
and the motor speed is approximately zero.
Aux Delay
(0.0 – 30.0 s)
EM brake engages,
for Aux Types 2, 3, and 4.

expired or when the motor speed approaches zero, whichever occurs
fi
rst. The
Interlock Brake Delay is adjustable from 0.0 to 8.0 seconds. When set to zero,
there is no delay and the brake is engaged as soon as the interlock switch opens.
Interlock braking will still occur until the motor speed hits zero.
For Aux Type 5, the interlock braking delay does not apply.
