The STO safety function test should be repeated at regular intervals (e.g. annually during the TUEV
inspection).

The following parameters in
fl
uence the deceleration paths:
•
V_1 (Positioning speed)
•
V_3 (Traveling speed)
•
R_NEG1 (upper round-off)
•
R_NEG2 (lower round-off)
•
A_NEG (Deceleration)
When a parameter is changed, the newly calculated deceleration path is indicated in the display after
con
fi
rming the change.
Travel
s31= 1.53m [ok]
To have some leeway to optimise the travel behaviour, the interrupt points should be set to a
deceleration path larger than that which was calculated.
Subsequent reduction of the creep path can be performed directly at the frequency inverter in the
menus
Delay/S_DI3
(for V_3) and
Delay/S_DI2
(for V_2).
To reach almost identical positioning in all
fl
oors, the interrupt points must be set with a precision of
±
1 cm
.
8.5.2
Cut-off points for travel speed V_1
To1prevent overshooting the
fl
ush alignment, the interrupt points V_1, dependent on the deceleration
A_NEG, must be set between
2 and 5 cm
before
fl
ush alignment. If the ride ends before alignment,
the interrupt points need to be correspondingly adjusted. To reach almost identical positioning in all
fl
oors, the interrupt points must be set with a precision of
±
1 mm
.

Carrying out the
fi
rst test run
Warning!
Operating synchronous motors without encoder offset can cause uncontrolled motor movements
In synchronous motors, an encoder offset calibration must be made prior to initial travel (see chapter
"Special functions/rotary encoder calibration")!
When a Ziehl-Abegg motor is purchased in connection with a frequency inverter, the offset
alignment is already taken care of.
If third-party motors are used, the offset must be performed as described in the chapter "Special
functions/rotary encoder calibration".
The
fi
rst trip must be carried out with the return control or as an inspection trip.
