INFORMATION
If the "STO SIL3" output is not used, 24 VDC must be applied to the "STO2­
ENABLE" input on the servo amplifier.
The single­pole digital outputs O0 … O3 signal the status of the safety functions. Outputs
are assigned to the signals in the safety card's Configurator. The following signals are avail­
able:
} SSA Safe Standstill Acknowledge
– 1: Motor is within the permitted limit values for standstill.
– 0: Standstill monitoring is inactive or motor is outside the standstill range
} SDA Safe Direction Acknowledge
– 1: Drive is moving in the permitted direction.
– 0: Drive is not moving in the permitted direction or monitoring is not activated.
} SRA Safe Range Acknowledge
– 1: Drive is moving within the permitted limit values for speed or position.
– 0: Drive is moving outside the permitted limit values for speed or position, or monit­
oring is not activated.
} SBA Safe Brake Acknowledge
– 1: Brake test was run within the defined period
– 0: Brake test must be activated within a selectable time period, otherwise the axis is
shut down.
The table below shows which outputs signal the status of which safety function.
