● Safety Parameter List
The following safety functions are presently able to be configured:
• Parameter 0: Function Input X10.22
• Parameter 1: Active-Time Delay
• Parameter 2: STO-Power-On-Test
Parameter 0 Value Range Explanation Note Flow Chart
Function
X10.22
Without Function
No safety relevance.
Function X10.22 is freely
programmable (BIAS)
Initial Factory Settings
(default values)
Acknowledgement
+ Emergency Stop
STO-function activation
through additional
lowhigh edge of the
X10.22 input
acknowledgement and
Emergency Stop before
the STO shutdown
through additional
highlow edge of the
X10.22 input.
See below
Acknowledgement
STO-function activation
through additional
lowhigh edge of the
X10.22 input
acknowledgement.
After the recognition
of the edge – the
active time delay will
be started!
Emergency Stop
Before the STO
shutdown through
additional highlow
edge of the X10.22
input.
After the recognition
of the edge, when the
rotational speed =0
then the emergency
stop ramp will be
executed and when
the rotational speed
=0, the time delay for
the brake will be
started!
Parameter 1 Value Range Explanation
Active-Time Delay
(in 10 ms
increments)
4 Initial Factory
Settings
(Default Value)
4- 500 (*10 ms)
Time delay for the activation of the final stage after
acknowledgement (24 V) of both STO inputs, for example of
the acknowledgement inputs (in the event that they have been
configured).
Note: If the STO inputs, for example, the acknowledgement
inputs are removed (0V) before the expiration of the active
time delay, then the time will be reset and only reactivated with
a new edge (24 V).
Parameter 2 Value Range Explanation
STO-Power-On-
Test
activate (0),(default)
deactivate (1)
The STO-Power-on-Test does not allow by deactivated STO
(STO1# and STO2# High) to activate the drive.
The 7-Segment-Display shows
. The drive will able to
activate after the safety function STO was activated and is
deactivate.
The safety function could activated by a safety gate or an
emergency stop
It is possible to use a PLC to automate this test.
