Type Name MB Register Default R/W Values Notes
uint16 Deadband (10=1.0%) 40053 5 R/W 0-250
Minimum percentage signal change to elicit a
movement response based upon end position of last
movement. For example, if the previous command
resulted in the actuator moving to 31.2% of travel and
deadband is set to 100 (10.0%), setpoint must
command valve to 21.2% or 41.2% before valve will
move to new position. Default is set set to minimize
signal dithering.
uint16
Low travel cutoff position
(100=10.0%)
40054 50 R/W 0-999
Analog input command, in percent with one implied
decimal (50=5.0%), below this value will result in the
valve plug moving to the closed position. Active in
both local and Modbus control modes.
uint16
Analog on/off close position
(100=10.0%)
40055 400 R/W 0-999
When the valve is in 4-20mA on/off mode, this value is
the point at which the valve will close. It must be set to
a smaller value than the analog on/off open position.
Percentage position value with one implied decimal
(400=40.0%).
uint16
Analog on/off open position
(100-10.0%)
40056 500 R/W 1-1000
When the valve is in 4-20mA on/off mode, this value is
the point at which the valve will open. It must be set to
a larger value than the analog on/off close position.
Percentage position value with one implied decimal
(500=50.0%).
uint16 Analog Close Value 40057 40 R 31 - 220
The analog value, in mA with one implied decimal
(40=4.0mA), that defines the closed position
uint16 Analog Open Value 40058 200 R 31 - 220
The analog value , in mA with one implied decimal
(200=20.0mA), that defines the open position
uint16 Number of retries 40059 2 R/W 0-4
When the valve plug encounters an obstruction, how
many attempts will it make to move past that point,
assuming no change in the command signal within the
deadband range.
