6.  Summary of Convenient Functions 

For trial run and maintenance/inspection and in emergency, automatic operation is released and 

manual position control is enabled.

For trial run and maintenance/inspection or in an emergency, operation can be suspended 

(stand-by or waiting action).  Then, the STBY lamp (green) on the front panel lights and control 

output stops.

For actions in automatic operation, switching of output characteristics, switching between 

operation and suspension, and position setting can be carried out by external input (no-voltage 

contact or open collector).  In case position setting has been made, the position used during the 

automatic operation is changed to a newly set value.  It takes an ON time of 0.2 seconds or 

longer for external input to become effective.  The following three types of setting modes by 

external input are available:

Three in total are selectable, i.e., switching of output characteristics, switching between 

operation and suspension (stand-by), and position setting.

In the mode used only for position setting, 7 values of position in total are selectable.  In this 

case, external input signals are treated as binary numerals.

3 values of position and one individual setting (switching of output characteristics, switching 

between operation/suspension (stand-by) or position setting) are selectable.

The position of the full closing and the opening of the control motor and the like are adjustable. 

Adjustments must be made before the testing operation.

Of the 9 functions; position higher/lower limit absolute value alarms, input from controller 

higher/lower limit absolute value alarms, automatic operation, manual operation, occurrence of 

position error, occurrence of error of input from controller error and control loop trouble; three 

can be selected as events (auxiliary output signals) for contact output.

A motor action which is safe enough at the time of a position error (error of electric potential 

input from control motor) or an input error (error of input signal from controller) can be set.

Selectable from 3 types: Suspension (stand-by action), closing and opening of motor by setting 

its action time.

Selectable from suspension (stand-by action) and setting of position (0~100%). 

   

The output of the position or the control input can be done.

Scaling (reverse scaling) is possible.

Communication setting is possible.  For details, please refer to the communication instruction 

manual.

To remove the noise content of input signals sent from controller.

To position output 0 to 100%, scaling (changing higher limit and/or lower limit) control output 

signal can be done freely in a range from - 10 to 110%. 

To control input signal 0 to 100%, scaling (changing higher limit and/or lower limit) control 

output signal can be done freely in a range from - 10 to 110%. 

Not effective during manual operation.  This is the function to make limiters (limitation) work 

on higher and lower limits of opening.  The function is used, for example, to avoid full opening 

or full closing.

In the case of combined output of SSR and contact, the motor speed can be adjusted by 

controlling ON time and OFF time of operating output to the motor during automatic operation.

Control is carried out by opening/closing operation of the position, using the square of input as 

a target position value.

Keylock means to lock keys so they cannot work when pressed.  There are four selectable types 

of keylock: Without keylock; keylock of screen groups 1 and 2; all keylock except manual 

operation; and all keylock.
