Finding the Encoder rotating direction
The following procedure describes how to find the encoder rotating direction.
34
Action
2. Connect the synchronization switch to the
encoder interface unit (DSQC 377) on the
controller.
Action
1. Tap: Inputs and Outputs symbol on the FlexPen-
dant.
2. Tap: View and select: I/O Units
3. Scroll down and selected: Qtrack - d377
4. Scroll down to c1position
5. Run the encoder in forward direction while
checking the value for C1Position.
If the number counts up:
• No action is required.
If the number counts down:
• the connection of the two encoder faces
(0° and 90°) must be interchanged.
