(Note 2) Cat. 4 requires test pulse for the purpose of safety input diagnose.
(Note 3) To use multiple safety functions, the lower safety level will be provided.
Ex.) When STO and SLS are used and Encoder configuration is Conf. 1, Safety level of Servo amplifier is SIL2, PL d, Cat.3.
(Note 4) Since STO and SBC do not monitor the encoder data, torque control can be used.
(Note 5) Except for STO and SBC, encoder data is monitored, however torque control can be used because the encoder is duplicated.
