Status-LEDs
The upper three LEDs show the state of the state machine within the basic unit SE-Power
FS, see
The state is read out from the basic unit SE-Power FS via communication
objects and then displayed.
The lower two LEDs display the status of the driver supply voltage.
Status display
Meaning
State
○ Normal operation
○ Safe Torque Off (STO)
○ Safety circuit error
All LEDs Off: The Functional Safety Module is not
initialized / not operational.
--
○ Normal operation
○ Safe Torque Off (STO)
○ Safety circuit error
Normal operation, which is "non-safe state".
The safety module FSM 2.0
– is initialized error-
free and operational.
Z2, Z3
○ Normal operation
○ Safe Torque Off (STO)
○ Safety circuit error
Safe state" SAFE TORQUE OFF, this means that
the power output stage of the basic unit SE-Power
FS is reliably switched off.
Z1
○ Normal operation
○ Safe Torque Off (STO)
○ Safety circuit error
The safety conditions are violated. The detected
state of the two driver supply voltages does not
comply with any of the defined valid states. The
PWM has been deactivated, the power output
stage is not reliable switched of, and that means
that the system is in a "non-safe state".

Click on this button to confirm a module replacement. Thereby, the integrated functional
safety is parameterised or projected. An existent error message due to a module
replacement will not be generated again after Save and Reset.
