This feature detects when the pump is running at maximum speed and the setpoint cannot be reached for a user-dened
time.
Motor alternation
The motor alternation functionality is suitable for applications with 2 motors or 2 pumps sharing 1 drive.
Deragging
This preventive or reactive pump cleaning feature is designed for pumps in wastewater applications.
Initial and nal ramp
Short ramp times to and from minimum speed protects bearings and ensures sucient cooling in applications with sub-
mersible pumps.
check valve protection
A slow ramp-down rate protects check valves and prevents water hammering.
Safe Torque O (STO)
STO enables safe stop (coast) when a critical situationsituation arises.
Low-ow detection
This feature detects no-ow or low-ow conditions of the system.
Pre/post lube
This feature supports a signal to an external device for lubricating mechanical parts to prevent damage and reduce wear
before and during operation.
Flow conrmation
This feature protects equipment from unexpected ow stoppage via communication to external devices, such as valves or
ow switches.
Pipe ll mode
Pipe ll mode comprises functionalities to ll pipes smoothly and avoid water hammering. This feature provides dierent
modes for horizontal and vertical pipes.
Sleep mode
The sleep mode feature saves energy by stopping the pump when there is no demand for the pump to run.
Real-time clock
This option includes back-up battery ensuring synchronization of real-time data.
Password protection
Overload protection
Smart logic control (SLC)
SLC comprises programming of a sequence consisting of events and actions. SLC oers a wide range of PLC functions using
comparators, logic rules, and timers. 4 SLC sequences can be programmed in parallel.
Advanced minimum speed monitoring for submersible pumps
The advanced minimum speed monitoring feature trips the drive if the speed drops below a certain value, protecting
pumps sensitive torwards low speed, for example, submersible pumps.
Freely programmable texts
Use freely programmable texts for information, warnings, and alerts.
Preventive maintenance
This feature enables programming of scheduled service intervals into the AC drive.
Condition-based monitoring
This feature enables warnings and alarms to be triggered when the actual lifetime of the product varies from the expected
lifetime reducing downtime, eliminating unexpected production stops and optizing the maintenance planning. All signals
are processed within the AC drive without need for cloud connection.
Adding to the exibility are the dierent ways of connectivity. The drive can be controlled:
