The Schneider Electric ATV340D11N4 is a high-performance machine drive. Its functions go far beyond simple motor speed control, focusing on dynamic response, industrial safety, and precision motion.
1. High-Performance Motion Functions
1ms Task Cycle: Features one of the fastest processing speeds in the industry, allowing the drive to react to sensor inputs or PLC commands in near real-time.
Closed-Loop Capability: When fitted with an optional encoder card, it provides exact position and speed feedback, essential for precision indexing and zero-speed torque.
Universal Motor Support: Optimized to run standard induction, high-efficiency Permanent Magnet (PM), and high-torque Synchronous Reluctance motors.
2. Integrated Safety Functions (SIL3/PLe)
It eliminates the need for many external safety components by embedding safety logic directly into the drive:
STO (Safe Torque Off): Standard protection to prevent accidental motor restarts.
SS1 (Safe Stop 1): Manages a safe, controlled deceleration during an emergency stop.
SLS (Safely Limited Speed): Ensures the motor stays below a safe speed during manual maintenance or machine setup.
3. Application-Specific Logic
Hoisting & Lifting: Includes dedicated Safe Brake Management logic to ensure heavy loads do not slip or drop during start/stop cycles.
Master/Slave (Load Sharing): Built-in software allows two drives to work together to drive a single mechanical load (like a long conveyor) by sharing the torque equally.
Multi-Motor Parallel: Can control several motors at once, provided they are within the drive's total current rating.
4. Rugged Industrial Reliability
Harsh Environment Ready: Boards are 3C3 and 3S3 coated, the highest grade for protection against chemical gases (like chlorine or ammonia) and conductive dust.
Predictive Maintenance: Monitors its own internal components (like the cooling fan) to alert you before a failure occurs.
