Allen-Bradley PowerFlex 70 Reference Manual

2-78 Digital Outputs
Digital Outputs Each drive provides digital (relay) outputs for external annunciation of a
variety of drive conditions. Each relay is a Form C (1 N.O. – 1 N.C. with
shared common) device whose contacts and associated terminals are rated
for a maximum of 250V AC or 220V DC. The table below shows
specifications and limits for each relay/contact.
Configuration
The outputs may be independently configured via the following parameters
to switch for various states of the drive.

[Digital Out2 Sel]
[Digital Out3 Sel]
Selects the drive status that will energize
a (CRx) output relay.
(1 )
Any relay programmed as Fault or
Alarm will energize (pick up) when
power is applied to drive and
deenergize (drop out) when a fault
or alarm exists. Relays selected for
other functions will energize only
when that condition exists and will
deenergize when condition is
removed.
(2)
Vector Control Option Only.
(3)
Activation level is defined in [Dig Outx
Level] below.
(4)
Vector firmware 3.001 and later.
(5)
When [TorqProve Cnfg] is set to
“Enable,” [Digital Out1 Sel] becomes
the brake control and any other
selection will be ignored.
