SET input Output
This input is used for a one-time alignment (zeroing) of the encoder immediately Output Default-function
after installation. A high control pulse (+V) applied to this input for a minimum A1 battery control
of 10 ms will reset the current encoder position to the pre-programmed setpoint
value. The default value is zero.

Notes:
• The SET function should only be implemented when the encoder shaft is at
rest.
• For the duration of the SET pulse the SSI interface does not function and
therefore does not output any valid position values! In order to avoid
malfunctions, no SSI clock pulse should occur during the SET pulse.
• If a cable wire is used to configure the SET input, then for EMC reasons
the wire should not remain open but should if at all possible be tied to 0 V,
provided no SET pulse is triggered!
• The response time of the SET input with +V = 5 ... 30 V DC power supply is 10 ms.
