Brake Adjust Block
Resistor Ohms
- This sets the Dynamic Braking Resistor value in Ohms. The dynamic braking
resistor can be internal (-E models) or external using optional RG, RGA or RBA assemblies. Care
should be exercised in selecting the proper amount of minimum resistance. Refer to Section 2 of
this manual for dynamic braking information. If dynamic braking is not used set the Resistor Ohms
to 0. The range of adjustment is 0-255 Ohms. The factory preset is 0. The last 2 digits of On RG,
RGA or RBA assembly catalog number is the resistor ohms.
Resistor Watts
- This sets the wattage value of the dynamic braking resistor(s). The dynamic
braking resistor can be internal (-E models) or external using optional RG, RGA or RBA assemblies.
Care should be taken in selecting the proper amount of power dissipation in watts. Refer to Section
2 of this manual for dynamic braking information. If dynamic braking is not used set the Resistor
Watts to 0. The range of adjustment is 0-32767 watts. The factory preset value is 0. The first 2 digits
of RG, RGA, or RBA assembly catalog number times 100 is the resistor watts.
Process Control Block
Process Feedback
- This parameter sets the source that will be used for process feedback input
to the control. The available selection includes: potentiometer, +/- 10 vdc, +/- 5 vdc, 4-20mA when
using the standard control without optional expansion boards; 0-10 vdc or 4-2OmA via the optional
High Resolution Expansion board, 3-15 PSI via an optional expansion board, or the optional
Tachometer expansion board.
Process Inverse
- This parameter inverts the feedback source in a unipolar fashion. This
parameter is intended to be used with reverse acting processes that use a unipolar signal such as 4-
20mA where 20mA will decrease speed and 4mA will increase motor speed. This parameter can be
turned ON or OFF. The factory preset is OFF.
Setpoint Source
- This parameter selects the source to which the process feedback will be
compared and controlled. The available choices are: potentiometer, +/- 10 vdc, +/- 5 vdc, 4-2OmA
when using the standard control without optional expansion boards; 0-10 vdc or 4-20mA via the
optional High Resolution Expansion board, 3-15 PSI via an optional expansion board, a tachometer
via an expansion board, serial via an optional serial communication expansion board or a FIXED
(software) PARAMETER which requires implementing the Setpoint Command parameter. The factory
preset is FIXED PARAMETER.
Setpoint Command
- This parameter is used only when the Setpoint Source is a FIXED
PARAMETER. This parameter is the input setpoint value that the control will try to maintain by
adjusting the motor speed. This parameter is scaled as a percentage of the process feedback input.
The programmable range is -100% to +100.0 % . The factory preset is 0.00%.
