Function
14 Friction torque characteristic with automatic plotting to optimize the speed
controller
15 Automatic optimization of the technology controller
16 The sign of the system deviation for the additional, free technology control‐
ler can be switched over.
A new parameter defines the sign of the system deviation matching the
particular application, e.g. for cooling or heating applications.
17 The technology controller output can be enabled and disabled during op‐
eration
18 Ramp-function generator remains active with enabled technology controller
19 Line contactor control using a digital output of the inverter to save energy
when the motor is switched off
20 Fast flying restart for PM330 Power Modules:
The "Flying restart" function does not have to wait for the motor demagnet‐
ization time, and identifies the motor speed without requiring a search op‐
eration.
21 Load torque monitoring extended to include the following functions:
● Protection against blocking, leakage and dry running operation in pump
applications
● Protection against blocking and broken belts in fan applications
22 Automatic switchover of the real time clock from daylight saving time (sum‐
mer time) to standard time (winter time).
23 New or revised default settings of the interfaces: p0015 macros 110, 112
and 120
24 Expansion of the temperature sensors to include DIN-Ni1000 for analog
inputs AI 2 and AI 3
25 Communication via AS-Interface.
Default setting of the communication via AS-i: p0015 macros 30, 31, 32
and 34
26 Communication expansion via Modbus:
Adjustable parity bit, access to parameters and analog inputs
27 Extending communication via BACnet:
Access to parameters and analog inputs
28 The bus error LED for communication via USS and Modbus can be switch‐
ed off
29 Default of the minimum speed to 20% of the rated motor speed
30 For commissioning with an operator panel, the inverter automatically backs
up the measured data retentively in the ROM after identification of the motor
data.
31 The result of the energy savings calculation for flow machines is available
as a connector
32 New "ppm" unit (parts per million) for unit switching
33 Displaying speeds during commissioning via operator panel in units of Hz
instead of rpm. Conversion from Hz to rpm via p8552
34 Voltage-dependent current limit for 600V devices of Power Module PM330
and PM240-2
Converter with the CU240B-2 and CU240E-2 Control Units
