Main Features:
The Starvert iP5a inverter is designed for vector control of pumps and fans, supporting a power range from 5.5 kW to 450 kW with a three-phase 400 V input. It offers multiple control methods including V/F, sensorless vector, and sensored vector control. The output frequency ranges from 0 to 120Hz, and it includes features like PID control, automatic carrier frequency change, and a flux braking algorithm. Optional features include a PLC board, I/O extension, and EMC filters up to 30kW. Communication protocols supported are RS-485 "LG BUS", ModBus/RTU, Profibus-DP, and DeviceNet.

Specifications:
The inverter provides a digital frequency resolution of 0.01Hz and an analog resolution of 0.6Hz. It maintains a frequency accuracy of 0.01% for digital commands and 0.1% for analog signals. The V/F curve can be linear, squared, or user-customized. Overload capacity is 120% for 1 minute and 150% for 30 seconds. Torque boost can be manual or automatic.

Operation and Control:
Operation methods include keypad, terminal block, and RS485 communication. Frequency settings can be adjusted digitally via keypad or analogically with various voltage and current inputs. Operating functions include PID control and 3-wire operation.

Input/Output Features:
The inverter has multi-function terminals for various operations such as forward/reverse operation, emergency stop, and frequency adjustments. Outputs include open collector and relay terminals, with analog outputs selectable from frequency, current, and voltage.

Protection and Alarms:
Protection features include overvoltage, undervoltage, overcurrent, inverter overheat, and motor thermal protection. Alarms cover issues like communication errors, phase loss, and hardware failures.

Environmental and Physical Specifications:
The inverter operates within an ambient temperature range of -10°C to 50°C and can be stored between -20°C and 65°C. It is designed for environments below 1000 meters altitude and 90% relative humidity without condensation. The device should be installed away from corrosive gases, combustible gases, oil mist, or dust.
