Feedback Configuration
Options The following feedback module combinations are supported.
An invalid hardware configuration results in a Module Fault: (Code 16#0010)
Mode or state of module does not allow object to perform requested service.
Considerations for Using Position Feedback Devices on the PowerFlex
755 in the Integrated Motion on EtherNet/IP Context
The PowerFlex 755 connects to position feedback devices (encoders) using one
or more feedback option modules that are placed in the PowerFlex 755 control
pod.
There are currently three supported types of feedback modules: 20-750-ENC-1,
20-750-DENC-1, and 20-750-UFB-1.
The 20-750-DENC-1 and 20-750-UFB-1 each contain two “hardware feedback
channels”, which means up to two encoders can be connected to each module.
The 20-750-ENC-1 only contains one hardware feedback channel.
Option Supported Module Catalog Number Valid Ports
Two Feedback Options Single Incremental Encoder 20-750-ENC-1 4…8
Dual Incremental Encoder 20-750-DENC-1 4…8
Universal Feedback 20-750-UFB-1 4…6
Two Feedback Options and
One Safe Torque Off
Option Single Incremental Encoder 20-750-ENC-1 4 and 5
Dual Incremental Encoder 20-750-DENC-1 4 and 5
Universal Feedback 20-750-UFB-1 4 and 5
Safe Torque Off 20-750-S 6
Two Feedback Options and
One Safe-Speed Monitor
Option
(1)
(1) The Safe Speed Monitor option module must be used with the 20-750-DENC-1 Dual Incremental Encoder module or the 20-750-
UFB-1 Universal Feedback module.
Single Incremental Encoder 20-750-ENC-1 4 and 5
Dual Incremental Encoder 20-750-DENC-1 4 and 5
Universal Feedback 20-750-UFB-1 4 and 5
Safe Speed Monitor 20-750-S1 6
IMPORTANT Single and dual incremental feedback options, 20-750-ENC-1 and 20-750-
DENC-1, cannot use registration inputs. Use the Universal Feedback option 20-
750-UFB-1 if registration homing inputs are needed.
