Absolute Encoder
ATM60 SSI
Zero-point adjustment*
ATM60 Encoders feature electric zero-point
adjustment.
The zero point can be adjusted in 2 ways:
• By pressing operating the button located
under PG cap on the back of the housing
• Via a SET line, which can be operated by
the control system
* The SET value can be freely defined using a
programming tool.
Zero-point adjustment using the button
Switch on the voltage. Move the drive shaft,
with the Encoder already mounted, to the
mechanical zero position. Remove the PG
cap. Press the button using a suitable , blunt
and non-conducting object for at least 40 ms.
Since the position value alters rapidly during
activation of the zero-point adjustment, ensu-
re that the drive shaft cannot move during
activation.
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 of
0.7*Us...Us, to the SET line, for at least 40 ms.
Since the position value alters rapidly during
activation of the zero-point adjustment, ensu-
re that the drive shaft cannot move during
activation.
Counting direction
The forward/backward input (V/R_) determi-
nes the Encoder’s counting direction.
If not connected, this input will be “HIGH”.
When, looking at the Encoder shaft and rota-
ting it clockwise (right turn), it will count in
ascending sequence. However, if it is
required that the encoder counts in
ascending sequence, with anticlockwise
rotation, then this connection must be
permanently connected to the “LOW” level
(GND).
Maintenance advice
ATM60 Encoders are maintenance-free.
We recommend regularly
- checking the mechanical fixings.
- checking the screw connections and
plug-in connections.
