Note 1. Set a value other than "00" for at least one of DI1 to DI6. Assign different devices to DI1 to DI6.
2. Set a value other than "00" for at least one of DO1 to DO4.
When [Pr. PSA02 Functional safety unit setting] is set to "_ _ _ 1" and [Pr. PSC03 Safety communication
- Servo motor rotation direction selection with functional safety] is set to "1 _ _ _", set the same value in
the servo amplifier's station number setting or rotary switch axis No. and the [Pr. PSC02 Safety
communication - Axis number selection] (_ _ x x).
(2) Parameters related to [Pr. PSA18 SSM speed]
Set [Pr. PSA18 SSM speed] to a value larger than the SSM hysteresis width ([Pr. PSA19 SSM
hysteresis width]).
(3) Parameters related to [Pr. PSD12 Input device - Noise rejection filtering time DI1] to [Pr. PSD17 Input
device - Noise rejection filtering time DI6].
Set [Pr. PSD12 Input device - Noise rejection filtering time DI1] to [Pr. PSD17 Input device - Noise
rejection filtering time DI6] to a value smaller than that of [Pr. PSD26 Input device - Test pulse off time].
