Its embedded graphical programming environment and advanced control features enable rapid development, fast commissioning, and reliable operation across a broad range of machine control and process automation applications.
 

Features

Benefits
PLC with graphical programming language
Eliminates the need for an external PLC by enabling process logic directly within the drive. Programs can be created using block diagrams, text-based code, state machines, and algorithms. All drive events, digital and analog I/O, and drive parameters can be used for position, speed, and torque control
PC-based configuration software
Simplifies commissioning and maintenance with fast setup for various motor types. Supports automatic and manual regulator tuning, real-time monitoring of drive parameters, a dual-channel oscilloscope, and advanced diagnostic tools
Fault and event logging
Stores fault and event history in non-volatile memory, preserving critical operational data even after power loss. Logged information includes timestamps and key operating values such as temperature, DC bus voltage, and load current
Configurable protection functions
Enhances equipment reliability and safety with protection against following error, overvoltage, undervoltage, overcurrent, short circuit, I²T overload, and overtemperature conditions. Supports automatic or manual fault reset and multiple fault indication and stop modes
Acceleration and deceleration profiles
Improves machine performance and reduces mechanical stress with configurable linear and S-curve acceleration/deceleration profiles, including optional acceleration limiting
Built-in tuning generators
Reduces setup time and optimizes performance with automated tuning of current and velocity control loops
