Below is a list of functions sorted according to the following categories:

Control modes

• Linear and quadratic torque characteristic for fluid flow and positive displacement machines
• ECO mode for additional energy saving in U/f control mode
• Sensorless vector control for sophisticated control tasks and high-output motors

Connections

• 2 analog inputs (current/voltage can be selected) to directly connect pressure/level sensors
• 2 additional analog inputs to connect Pt1000/LG‑Ni1000/DIN‑Ni1000 temperature sensors
• Direct control of valves and flaps using two 230 V AC relays

Interfaces

• PROFINET, EtherNet/IP, PROFIBUS, USS, BACnet MS/TP, FLN P1, and Modbus-RTU communication

Software functions

• Automatic restart function after power failure
• Automatic restart
• Flying restart
• Skip frequencies
• 1 PID controller for the closed-loop control of the motor speed as process controller for temperature, pressure, air quality or levels
• 3 freely-programmable PID controllers
• Hibernation mode
• Load check function to monitor belts and flow
• Cascade connection
• Multi-zone controller
• Essential service mode
• Real time clock with three time generators

IOP‑2 wizards for special applications with and without PID controller, such as

• Pumps: Positive displacement (constant load torque) and centrifugal pumps (quadratic load torque)
• Fans: Radial and axial fans (quadratic load torque)
• Compressors: Positive displacement (constant load torque) and fluid flow machines (quadratic load torque)
