Control Options
What is a Control Option?
Group 29 Beck drives have a model number 29-100. This drive has the
capability to be equipped with different electronics combinations, which
are called control options. The control option number will replace the
last zero in the model number when specifying a drive model and
control option. For example, a model 29-100 drive that is setup to use
the control option 9 electronics would be considered a model 29-109
drive. A basic description for each control option is provided below. For
details on the electronics components, please visit the Group 29
Electronics section.

CONTROL OPTION 9 - The standard modulating drive offering, model
29-109 is the control option 9. Control option 9 units are equipped with
the Beck DCM (Digital Control Module) and CPS (Contactless Position
Sensor). The option 9 drives may be controlled with a 4-20 mA or 1-
5Vdc signal and have an integral 4-20 mA position feedback signal. The
microprocessor based DCM provides a multitude of flexibility for setup,
calibration, and diagnostics including HART communications, on-board
pushbuttons for calibrating stroke, on-board diagnostic status, stall
protection circuitry, and status alerts. Typical Arrangement
CONTROL OPTION 3 - The control option 3 drive is an open/close unit
controlled with 120 VAC direct to the motor. When the drive hits the
limit switch at either of the two end-of-travel positions, power is cut to
the motor. Typical Arrangement
