5.5 Changing I/O Signal Allocation
I/O signal assignment can be changed as appropriate from initial settings. There may be cases when changing to
the Input/output signal assignment are required for actuator operation.
Please be aware that any changes will alter signals entered as initial settings.
Please allocate them according to your system specification.
*When configuring PD**, please set parameter write inhibit [PA19] to 000C.
See “LECSB Operation Manual”, section 5.4 for details.
5.5.1 Automatic Input Signal ON Selection Parameter Configuration
Configure the input signal automatic ON selection parameter.
The parameter
“PD01
:
Input signal automatic ON selection” settings, defines which input signals will turn ON
automatically when the control circuit power supply is turned on., doing this allows additional I/O signal selection
range.
Please allocate it according to your system specification.
Configure the automatic ON selection in parameter [PD01], or wire the I/O signal layout.
If I/O signal wiring layout is altered, do not configure PD01
:
Input signal automatic ON selection.
(Ex.)If the servo-on(SON) is automatically turned on with PD01, the actuator will always be in the
servo-on state when the control circuit power supply is turned on.
Therefore, it is not possible to operate servo-on/servo-off from the I/O signal.
Please configure PD01
:
Input signal automatic ON selection in Hexadecimal (HEX).
During Actuator Operation: <Signals which must be ON during actuator operation>
Set PD01 as 0C04. The following signals will automatically turn on when power supply turns on.
SON
Servo-on
OFF
:
Servo-off
ON
:
Servo-on (operational)
LSP
Forward rotaion Stroke end
(normally closed contact)
OFF
:
Forward rotaion Stroke end
ON
:
Forward rotaion Stroke end off (operational)
LSN
Reverse rotaion Stroke end
(normally closed contact)
OFF
:
Reverse rotaion Stroke end
ON
:
Reverse rotaion Stroke end off (operational)
Note) In order to operate the actuator, EMG (Emergency stop) is required to be ON (operational) state.
However, for EMG (Emergency stop) can not be forced to automatic ON set by the parameter, please make
sure it is physically wired.
