Features of the safety function:
The motor becomes torque-free and no longer generates any hazard-
ous movements.
The safety function "safe stop 1" corresponds to a category 1 stop
(controlled braking) in accordance with EN 60204-1.
In the Configurator, the braking ramp is specified and monitoring is
activated. The braking period depends on the speed of the motor
The drive starts with the configured braking ramp when safety func-
tion SS1 has been activated. Once the time has elapsed, STO is ac-
tivated.
The drive starts with the configured braking ramp when
- there is an internal error
- limit values are exceeded
Safety function STO is activated when
- the actual braking period is longer than the configured STO delay
time.
- the configured limit value for the position error is exceeded.
- another error occurs while SS1 is activated
- the STO delay time has elapsed
Automatic STO at standstill
A standstill threshold for activating the safety function STO can be
Safety function STO is activated when
- standstill is achieved while the STO delay time is running.
- the STO delay time has elapsed.
"Ready" output: "1" Signal (+24 VDC). The safety card is ready for op-
eration.
To achieve SIL3 or Ple: Connect the output "STO SIL3" to servo am-
