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.

sequencing delay and main

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.
