016 Position Drift1 (drift monitoring at standstill):
Important notes for DS240 / DS246 see chapter 7.4.1
This Parameter handles drift movements at standstill. If the period
time of the input frequency exceeds the adjusted „Wait-Time“ (see
parameter 002), the sensor is assigned to frequency = 0, even if a
slow drift movement is present.
In case of an illegal drift, this Parameter allows to preset an error
threshold (symmetrical position /- xxx pulses). The
monitoring is only performed at standstill and begins at position 0,
immediately when frequency = 0 is detected.
0
Drift monitoring not active
xxx An error message appears, when the position is drifting
out of the adjusted window of +/- xxx pulses (single
edge evaluation).

017 Phase Err Count1
(faulty pulse counting limit)
:
Important notes for DS240 / DS246 see chapter 7.4.1
The DS unit is able to detect incorrect pulse sequences as well as
faulty phase positions.
The error status will be released if the adjusted number of faulty
pulses is exceeded.
Incorrect pulses can be caused by faulty wirings, EMC-problems,
incorrect mode settings, when turn up the encoder supply or when
reverse the direction Parameter.

018 Set Frequency1
(simulation of a fixed encoder frequency)
:
This Parameter is used for test purposes and allows to substitute
the real encoder frequency by a fixed frequency.
The setting will take effect, if
- the unit state (DIL switch) = “Programming Mode” and
- the setting of Parameter 62 = 7 (see also chapter 7.4.7 )

When using two encoders with differing pulse rates or in case of a mechanical reduction between
both encoders, the higher frequency must be converted to the lower frequency by using the
scaling factors (see chapter
8. ).
