Alternative solutions for airbag safety systems in industrial doors?

• If the door encounters an obstacle while descending, the motor automatically detects resistance changes and either stops or reverses to prevent impact injuries.
• This feature complements the airbag system, ensuring operational safety even if one protective mechanism fails.

This design significantly enhances equipment safety and reliability, delivering comprehensive protection for both personnel and goods.

Automatic Rebound/Stop Working Principle: The system responds based on the real-time current during the closing operation (when the motor encounters an obstacle, the torque increases, which leads to a higher current).

Operatio steps

1. Check and record “the max real-time current value during closing” via “Info → Inquiry → No. 2” . Make sure that the voltage in site is stable.

2. Set the failure height: In “Adv. Parameter → Index 75”, “0000” means this function is disabled; “0005” means 5% of the district from the opening/closing limit.

3. Switch between obstruction stop and rebound: In “Adv. Parameter → Index 73”, “0000” means STOP, and “0001” means REBOUND (default is STOP).
