Number of additional steps to achieve
Ec 20
complete closure. When a closing request is
received, the valve starts from the current
number of steps and moves to 0, then closes
for the set number of steps.
For unipolar valves refer to the notes included
in paragraph 7.3.
Number of return steps in opening mode after
Ec 21
the valve has been closed completely. These
decompress any closing spring inside the valve
or to prevent sealing the circuit.
For unipolar valves refer to the notes included
in paragraph 7.3.
Maximum number of adjusting steps of the
Ec 22
valve 2
(this value is set automatically by the controller
if EC18> 0).
For unipolar valves refer to the notes included
in paragraph 7.3.
Minimum number of adjusting steps of the
Ec 23
valve 2
(this value is set automatically by the controller
if EC18> 0).
For unipolar valves refer to the notes included
in paragraph 7.3.
Maximum current value per phase of the
Ec 24
stepper motor
(this value is set automatically by the controller
if EC18> 0)
Current stand-by value
Ec 25
(this value is set automatically by the controller
if EC18> 0)
Maximum number of steps per second of the
Ec 26
valve.
For unipolar valves refer to the notes included
in paragraph 7.3.
