How do I program and wire an E‑Stop for an ATV212 (Altivar 212) drive?

To safely integrate an emergency stop (E‑Stop) using a run permissive on the ATV212 drive, follow these steps:

1. Wiring

• Use a normally closed (NC) E‑Stop contact.
• Connect the contact between terminals R and P24.
• This ensures the circuit opens when the E‑Stop is pressed.

2. Programming

• Set parameter F110 = 0 (assigns the input function).
• Set parameter F112 = 1 (enables run permissive logic).

3. Operation

• When the E‑Stop is activated (contact opens), the drive:
  • Removes output power to the motor
  • Displays “OFF”, indicating the run permissive is not active
• Normal operation resumes only when the circuit is restored.

Tip: Using a run permissive ensures the motor stops immediately when the safety circuit is interrupted.
