Introduction
1.4 Adapting the inverter in line with the application
Inverter with CU240B-2 and CU240E-2 Control Units
Operating Instructions, 07/2010, FW 4.3.2, A5E02299792B AA
17
● New functions are assigned to the digital inputs (P0701 ... P0713)
● New functions are assigned to the digital outputs (P0731 ... P0733)
● Inverter control is interconnected with the signals from the digital inputs (P0800, P0801,
P0840, etc.)
You will find more information about follow-on parameterization for P0700 in the List Manual.
1.4.4 Parameter changes, which subsequently result in internal calculations
When changing the following parameters, the inverter is busy with internal calculations for
several seconds. During this time, no entries are possible.
● p0014 Buffer mode
● p0340 Calculation of control parameters
● p0970 DO/reset drive
● p0971 DO/save drive
● p1082 Maximum speed
● p3235 Phase failure monitoring time
● p3900 Completion quick commissioning
● p1030 Motorized potentiometer config
● p2230 Tech motorized potentiometer config
● p0918 PROFIBUS address
● p2020 Fieldbus baud rate
● p2021 Fieldbus address
● p2030 Fieldbus selection
● p2042 PROFIBUS ident
● p8620 CAN address
● p0804 Data copy, MMC - flash
● p1900 MotID
This state "busy with internal calculations" is displayed as follows:
● at the BOP-2: "Busy"
● at the IOP: Progress bars
Further, the state can also be read-out using p3996:
● r3996 = 0 Inputs possible
● r3996 > 0 Inverter busy, inputs not possible
