Control inputs
V/R input for change of direction Note:
The encoder can output increasing code values when the shaft is rotated either • Any hardware configuration of the V/R input must take place BEFORE
clockwise or counter-clockwise (when looking from the shaft side). powering up the encoder!
The appropriate option can be selected via a hardware configuration of the V/R • If the V/R input is not configured, then a 0 V configuration will apply
input BEFORE powering up the encoder. (default condition)!
The following table shows the function selection dependent on hardware and • If the direction of rotation is changed due to the V/R configuration, without
software settings: activating the SET function again, and if the encoder is also then powered
up again, a new position value may be outputted, even if the physical shaft
Hardware configuration Function: position of the encoder has not moved! This is due to internal conversion
of the V/R input: increasing code value when the shaft is in the processes.
following direction
• The start-up procedure for the encoder should therefore follow this sequence:
„LOW“ 1. Determine the count direction of the encoder either via the V/R input or via
(0V) on the V/R input (=cw) cw
programming
„HIGH“ 2. Apply power to the encoder
(+V) on the V/R input (= ccw) ccw
3. Activate the SET function, if desired (see SET input below)
„LOW“
(0V) on the V/R input (=cw) ccw • If using a cable wire to configure the V/R input, then for EMC reasons the wire
should not remain open but should be tied either to 0 V or +V!
„HIGH“
(+V) on the V/R input (= ccw) ccw • The response time of the V/R input with +V = 5 ... 30 V DC power supply is
10 ms.
3) Only one channel allowed to be shorted-out:
1) For shaft version only (at shaft end). at +V = 5 V DC short circuit to channel, 0 V, or +V is permitted.
2) If power supply +V correctly applied. at +V * 5 ... 30 V DC short circuit to channel or 0 V is permitted.
4) The power supply at the encoder input must not be less than 4.75 V (5 V - 5%).
