Frame 3 drives (firmware version 1.x) only:
Figure 74 - Dig Out Status (217) Frame 3
On the Frame 3 drive, AC Line I/O Board Digital Output 1 is used to control
the shunt trip, and various conditions inside the drive can cause the shunt trip to
be commanded.
•
A 1 in bit 0 indicates that the shunt trip is being commanded (breaker
commanded open).
•
A 0 in bit 0 indicates that the shunt trip is not being commanded.
AC Line I/O Board Digital Outputs 1...6 are also called the application digital
outputs
. They are commanded by the inverter using bits 0...5 of rectifier
parameter Rectifier Contrl (100), but you should not write to this parameter.
You can control these outputs using inverter parameter Appl Digital Out (30).
For AC Line I/O Board Digital Output 1, this shunt trip control via rectifier
parameter Rectifier Contrl (100) is in addition to the internal rectifier conditions
that can cause a shunt trip.
Frame 4 drives (firmware version 2.x) only:
Figure 75 - Dig Out Status (217) Frame 4
On the Frame 4 drive, the Combined I/O Board dedicated Shunt Trip output is
used to control the shunt trip, and various conditions inside the drive can cause
the shunt trip to be commanded.
•
A 1 in bit 0 of this parameter indicates that the shunt trip is being
commanded (breaker commanded open).
•
A 0 in bit 0 indicates that the shunt trip is not being commanded.
