Reading parameters

Read access enables direct reading of all parameters of the frequency inverter. This is useful if
the parameter is not connected to a source. Since the read access is effected to the non-
realtime system of the frequency inverter, an instruction may take longer than 1 ms. The in-
struction is processed for the duration of the parameter access even if this takes longer than 1
ms.
If a non-permissible data set or index is selected, it will be replaced by one of the following
data sets or indices.
Data Set/
Index
0
1...4/
1...max. index
Invalid value
All data sets are accessed from the RAM. Internal access to the EEPROM and RAM is done in
the same way.

I2
I3 b Release read access
- -
I4
Description:
The function reads the value of the parameter set up in P1 "Parameter number" and P2 "Data
set/index". The value is converted to a frequency value. Via Input I3 read access is enabled.
I3 = 0: No read access.
I3 = 1: The parameter value is read. The instruction is executed until the value is read.

Description:
The function reads the value of the parameter set up in P1 "Parameter number" and P2 "Data
set/index". The value is converted to a current value. Via Input I3 read access is enabled.
I3 = 0: No read access.
I3 = 1: The parameter value is read. The instruction is executed until the value is read.
