5. Actuator would not operate without servo-on and pause signals.
(1) Servo ON Signal (SON)
The servo-on signal (SON) is available to select whether to enable or disable in the initial
setting process “Servo Control”.
If it is set to “Enable”, the actuator would not operate unless turning this signal ON.
If parameter No.21 is set to “Not to use”, SON is made disable. If it is set to “Disable”, the
servo becomes on and the actuator operation becomes enabled as soon as the power
supply to the controller is turned ON and the emergency stop signal is cancelled.
Have the setting that suits to the desirable control logic.

(2) Pause Signal (STP, *STP)
If Single Solenoid is selected and the stop signal is set to “Use” in the initial setting, unless
this signal is enabled, the actuator would not operate.
If this signal is not to be used, set the stop signal to “Not to use” in the initial setting
process.
If not in use, the operation of the actuator is available even with this signal not being
enabled.
6. Clock Setting in Calendar Function
There may be a case in the first time to supply the power after delivery that Gateway Error
Code 4A “Real Time Clock Vibration Stop Detected” is generated. In the case this happens, set
the current time with a teaching tool.
If the battery is fully charged, the clock data is retained for approximately 10 days after the
power is turned OFF.
Even though the time setting is conducted before the product is shipped, the battery is not fully
charged. Therefore, there may be a case that the clock data is lost even if the days described
above have not passed.
7. Rotary actuator cannot be set to Multi-Rotation Specification.
Rotary actuator cannot be set to Multi-Rotation Specification since the index mode setting
cannot be performed.

8. The controller is not applicable for the high output function.
This controller does not respond to the high output even if it is connected to an actuator that is
applicable for the high output function. It provides the operation in normal output.
