AR7257-04 - KSB PumpDrive-R, 45 kW, PDRVR_045K00, IP20 + circuit boards sealing + Profibus

Self-cooled frequency converter (FC) that enables continuous speed control of asynchronous and synchronous motors.

Protection functions:
Full drive protection through overcurrent limitation and PTC thermistor monitoring
Automatic speed reduction in case of overload and overtemperature, phase failure protection, motor-side short-circuit monitoring, over/undervoltage monitoring
Suppression of resonance frequencies
Cable break monitoring (live zero)
Dry-running protection and hydraulic blockage protection
Characteristic map monitoring
Emergency operation with reduced speed in case of overtemperature, undervoltage, or failure of a mains phase

Control/Regulation:
Actuator operation via setpoint specification (analog and digital input, display, fieldbus)
Freely selectable maximum speed (0 to 590 Hz)
Control operation via integrated PID controller
Control variables are pressure, temperature, level, flow rate
Sensorless differential pressure control
Sensorless flow rate control
Sensorless flow rate-dependent pressure setpoint adjustment for compensating pipe friction losses (DFS function) for improved energy savings
Flow rate estimation
Alternative setpoint
Pump operating cycle
Smart Logic function with 10 Actions for Simple Drive Tasks

Operation and Display:
Display for showing measured values and alarms and for parameterization, including fault history, operating hours counter (motor, frequency converter)
Operating point display (Q, H)
Energy saving counter
Service interface for connection to computer software
Quick menu for brief commissioning of PumpDrive functions
Programmable acceleration and deceleration ramps
Vector control with switchable motor control method (ASM, SuPremE)
Automatic motor adaptation, overridable by parameterization
Manual-0-Automatic operation
Standby operation (Standby mode)
Deragging function

Installation options:
Optional support for Profibus DP, Modbus TCP, ProfiNet, Ethernet/IP, or DeviceNet
