Analog Speed Follower and Preset Speed
Drive Configuration
The PowerFlex 700 drive will be an Analog Speed Follower, a Preset Speed
module, or possibly controlled via a communication network.
The information in this Chapter covers the hardwire stand-alone configurations
of Analog Speed Follower and Preset Speed.
Analog Speed Follower
The PowerFlex 750-Series drive can be configured so an analog source is its speed
reference. The default configuration is selected to be Port 1 but the drive can be
configured to follow a +/- 10V DC source, 0-10V DC source, or 4-20 mA source
with the onboard analog inputs on the PowerFlex 753 drive or with an optional
I/O module.
There are three common examples with the PowerFlex 700 drive using different
speed-reference inputs along with hardwired Start/Stop/Direction control and
the equivalent PowerFlex 750-Series configurations.
Three-wire Control with Analog Speed Reference
The three-wire control method is Start/Stop/Direction. The digital control
inputs use the drive’s internal 24V DC supply, and the analog speed follower
reference uses a 10K
Ώ potentiometer wired to the drive’s internal 10V DC
power supply.
