CoreTech Encoder
Zero-point adjustment ARS 60
Zero-pulse assignment DRS 60/DRS 61
CoreTech encoders have electrical zero-point
adjustment.
The zero-point adjustment can be carried out
in 2 ways:
• Operate the push button located under
the PG cap
• Via a SET line*, which can be operated
from the control system (not possible in
all designs, see pin allocation)
* Not available in DRS 60/DRS 61
incremental encoders

Zero-point adjustment/Zero-pulse
assignment using the push button
Switch on the voltage. Set the drive shaft,
with the encoder mounted, to the mechanical
zero position. Remove the PG cap. Operate
the push button with a suitable, blunt and
non-conducting object for at least 40 ms.
Since the position value alters rapidly during
zero adjustment/zero-pulse assignment, care
must be taken to ensure that the drive shaft
remains stationary during adjustment.
Refit the PG cap.
Zero-point adjustment using the SET line*
Switch on the voltage. Move the drive shaft,
with the encoder already mounted, to the
mechanical zero position. Apply a level
between 0.7*Us...Us to the SET line for a
period of at least 40 ms. Since the position
value alters rapidly during zero adjustment,
care must be taken to ensure that the drive
shaft remains stationary during adjustment.
