If a fixed PKW length is selected only one parameter value can be transferred.
In the case of indexed parameter, you must use the variable PKW length if you wish to have the values of
all indices transferred in a single telegram.
In selecting the fixed PKW length, it is important to ensure the value in question can be transferred using
this PKW length.
P2013 = 3, fixes PKW length, but does not allow access to many parameter values.
A parameter fault is generated when an out-of-range value is used. The value will not be accepted but the
converter state will not be affected.
Useful for applications where parameters are not changed, but MM3s are also used.
Broadcast mode is not possible with this setting.
P2013 = 4, fixes PKW length.
Allows access to all parameters, but indexed parameters can only be read one index at a time.
Word order for single word values are different to setting 3 or 127, see example below.
P2013 = 127, most useful setting.
PKW reply length varies depending on the amount of information needed.
Can read fault information and all indices of a parameter with a single telegram with this setting.
Example:
Set P0700 to value 5 (P0700 = 2BC (hex))
P2013 = 3
P2013 = 4
P2013 = 127

Index 0 defines a time T_off after which a fault will be generated (F72) if no telegram is received via the
USS/MODBUS channel RS485.
Index 1 defines a time T_off after which a fault will be generated (F71) if no telegram is received via the
USS channel RS232 (reserved).
Index:
[0]
USS/MODBUS on RS485
[1]
USS on RS232 (reserved)
Notice:
If time set to 0, no fault is generated (i.e. watchdog disabled).
Note:
The telegram off time will function on RS485 regardless of the protocol set in P2023.
