[Pr. Pf18_Sto Diagnosis Error Detection Time (**Stod)]; [Pr. Pf19_Friction Failure Prediction - Compensation Coefficient 1 (Tsl)] - Mitsubishi Electric MELSERVO-J5 MR-J5-G User Manual

[Pr. PF18_STO diagnosis error detection time (**STOD)]

Initial value
10 [s]
Set the time from when the error of the STO input or STO circuit is detected until the occurrence of [AL. 068.1 STO signal
mismatch error].
When "0" is set, [AL. 068.1] is not detected.
The safety level depends on the setting value of this servo parameter and whether STO input diagnosis is performed by TOFB
output as shown in the following table.
Setting value
0
1 to 60
When the STO function is not used with the short-circuit connector connected to the CN8 connector, the safety level does not
change even after setting this servo parameter.
This servo parameter cannot be used with the MR-J5-_G_-RJ or the MR-J5W_-G_.
The alarm occurs when an STO input error is detected.
Refer to the following table for details.

[Pr. PF19_Friction failure prediction - Compensation coefficient 1
(TSL)]
Initial value
0 [0.0001 %/°C]
Set compensation coefficient 1 to compensate the dynamic friction being used for the friction failure prediction.
When the friction failure prediction warning selection is set to the automatic threshold setting, the value will be calculated
automatically from the estimated dynamic friction.
When performing threshold manual setting on an equipment for which the threshold setting has been made once, set the
value that has been calculated by the threshold automatic setting.
Setting this servo parameter decreases the possibility of erroneous detection of friction failure prediction, even with the
manual threshold setting.
