How can I configure an ATV312 drive for forward and reverse using a ±10 V speed reference?
Resolution:
This setup allows you to control both direction (forward/reverse) and speed using a single analog input signal ranging from +10 V to -10 V. Positive voltage commands forward rotation, while negative voltage commands reverse rotation.
Follow these steps to configure the drive:
-
Assign the speed reference:
- Set parameter FR1 (Reference Channel 1) to AI2 in the CTL (Control) menu.
-
Wire the analog input:
- Connect the ±10 V signal between AI2 and COM on the drive.
-
Operation:
- Positive voltage (+) → Forward direction
- Negative voltage (-) → Reverse direction
- The voltage level determines the speed in each direction.
This configuration enables bi-directional control using a single analog signal input, simplifying wiring and control logic.
