No. Symbol Name and function
Initial
value
[unit]
Setting
range
PSA20 **SMERL Servo motor encoder resolution - Lower
Set an encoder resolution of the servo motor.
Set lower four digits in decimal numbers with this parameter.
4304
[pulse/
rev]
0
to
9999
PSA21 **SMERH Servo motor encoder resolution - Upper
Set an encoder resolution of the servo motor.
Set upper four digits in decimal numbers with this parameter.
Do not set "0" for the servo motor encoder resolution ("0" for both [Pr. PSA20] and [Pr.
PSA21]).
Setting "0" will trigger [AL. 7A.3 Parameter combination error (safety observation function)].
When the values set for the servo motor encoder resolution ([Pr. PSA20] and [Pr. PSA21])
do not match with the resolution of the actually connected encoder, [AL. 7A.3 Parameter
combination error (safety observation function)] will occur.
Refer to section 7.2 for details.

PSA22 **SAADT Position feedback fixing error detection time
Set a time until [AL. 79.8 Position feedback fixing error] is detected.
Setting "0" will disable a diagnosis for [AL. 79.8 Position feedback fixing error].
In addition, when servo motors with functional safety are used, detection of [AL. 79.8] is not
performed.

PSC01 **SNC Safety communication - Communication cycle
Select a communication cycle for the safety communication.
Set the same value as of the controller to "Safety communication - Communication cycle". When a different
value is set, [AL. 7C.1 Functional safety unit communication setting error (safety observation function)] will
occur.
