1336 FORCE Adjustable Frequency AC Drive
An adjustable frequency AC drive produced by Rockwell Automation. Most of the
construction and components of the RGU power structure are equivalent to the
1336 FORCE drive.
Analog Input (A/D Conversion)
The RGU has two analog inputs. The RGU can convert analog DC voltage inputs into
digital values that can be used in the RGU.
Analog Output (D/A Conversion)
The RGU has two analog outputs. The RGU can convert internal digital values into
analog DC voltages that can be output to a connected analog device.
Control Power Filter
A filter used to reduce harmonics and noise in the 115V AC control power.
Current Loop
A portion of firmware which is responsible for sending a current command to the
hardware. The current bandwidth determines the number of current commands to be
made per second, and the current damping determines the precision of the current
command process.
Current Transducer
A torroid that is typically used for AC feedback.
Digital Signal Processor (DSP)
The digital signal processor which is located on the main control board of the RGU. This
component processes current commands for the RGU.
Disable
When a unit is disabled, the control logic is not directing current flow operations. A unit is
typically disabled by a disable command or by a fault condition.
Disconnect
A circuit breaking device.
DriveTools
A software application which can be interfaced with the RGU. DriveTools includes tools
which can be used to configure, monitor, and control the RGU and other drive system
products.
