◾ Load torque monitoring
◾ Real-time clock
◾ 3 freely programmable
digital time switches
◾ Display of the energy consumption
◾ Free function blocks
◾ PID controller
◾ Bypass
◾ Cascading drives
Communication interfaces – simple and direct integration into the automation environment
◾ Different communication interfaces
• RS485 with USS protocol
• Modbus RTU, BACNet MS/TP
• Siemens FLN P1
• PROFIBUS DP
• CANopen
◾ External 24 V power supply
Special functions for optimum use in building technology
◾ 3 additional, integrated,
freely programmable PID controllers
◾ Multi-zone closed-loop control
◾ Extended operation in the case of fire
(essential service mode)
◾ Automatic acknowledgment of the fault after a power failure
and automatic restart
◾ Synchronization of the inverter to a motor
that is still rotating
◾ Resonance points of the mechanical system
and piping can be skipped
◾ Monitoring of the drive for dry running protection,
blocked protection and belt monitoring
◾ Precise time stamp for fault and alarm logging,
buffer time of up to 5 days
◾ Three selectable events can be controlled
as a function of the weekday / hour / minute
◾ Display of the electrical energy used
◾ Display of the energy saved when compared
to a control with throttle valve
◾ Flexible use of integrated functions for optimum
use in building technology, additional, external
components can be eliminated
◾ Closed-loop drive speed control as a function
of process variables such as temperature,
pressure, flow, air quality
◾ Automatic switchover to line operation for
faults or when the rated speed is reached
◾ Energy-efficient adaptation of the flow rate by
switching in/switching out up to three fixed-speed drives
◾ Simple integration into building management systems,
process control systems and automation systems
◾ Bus is not interrupted when the inverter is in the off state
◾ Distributed control of flaps,
heating and cooling valves without any additional control
◾ Control of pressure, temperature, air quality in up to
three zones (average value, minimum, maximum) with
a setpoint that can be switched over
◾ Maximum operating time of the drive in case
of fire by changing the setpoints, suppressing
faults and automatic restart
