6. Parameter Settings

z Servo-on Input Disable Selection (No.21 FPIO)

Parameter No. 21 is used to set whether enable or disable the servo-on input signal.

Setting

Enable (Use)

Disable (Do not use)

The factory setting is “0” [Enable].

z SIO Communication Speed (No.16 BRSL)

This parameter is not used with this controller. It applies to controllers of serial communication type.
If this parameter is set, it sets the communication speed to be used when the controller implements serial communication
control via the PLC’s communication module.
Set Parameter No. 16 to a value appropriate for the specification of the communication module.
9600, 19200, 38400 or 115200 bps can be selected as the communication speed.
The factory setting is “38400” bps.

z Minimum Delay Time for Slave Transmitter Activation (No.17 RTIM)

This parameter is not used with this controller. It applies to controllers of serial communication type.
If this parameter is set, it defines the minimum delay before the controller’s transmitter is activated following the completion of
command reception, when the controller implements serial communication control via the PLC’s communication module.
The factory setting is “5” msec. If the communication module specification exceeds 5 msec, set the required time in Parameter
No. 17.

z Silent Interval Multiplication Factor (No.45 SIVM)

This parameter is not used with this controller. It applies to RS485 serial communication commands.
If this parameter is set, it defines the multiplication factor of silent interval time to be used for delimiter judgment in the RTU
mode.
The factory setting is the communication time corresponding to 3.5 characters in accordance with the Modbus specification.
This parameter need not be changed in normal conditions of use where the actuator is operated using a PC or teaching
pendant.
If the character sending interval exceeds the silent interval because the scan time of the PLC is not ideal, however, you can
extend the silent interval time through Parameter No. 45.
The minimum setting unit is 1 (times), and the input range is 0 to 10. If “0” is set, it means that the silent interval multiplication
factor is disabled.
