Brake Trouble Internal Timer

Brake Fault Timer
This parameter is used in conjunction with the discrete input terminal setting
64 [ System Consistent Sequence (BA: braking answer)] (see item 64 of Table
14 on pg. 189 for further information on this feature).
After activating the discrete input terminal System Consistent Sequence (B:
braking release), the setting of this parameter defines a window of time in
which 1) a
Braking Answer response must be received or 2) the brake must
release.
Should this timer setting expire before the Braking Answer is returned or the
brake releases, a Brake Fault is incurred. Otherwise, the brake releases and
normal motor operations resume.


Special Control

Earth Fault
This parameter sets the threshold level (%) that must be exceeded to meet the
Earth Fault Alarm activation criteria.

Earth Fault Alarm Time
Program

Special Control

Earth Fault
In the event that the Earth Fault Alarm activation criteria is met, a timer
begins to count down to zero. Upon reaching zero, the Earth Fault Alarm is
activated.
This parameter sets the start-time of the count-down timer.
