Response to modified safety-related parameters
If modified safety-related parameters are received during run-up, the parameters are
displayed. Confirm the modified parameters by pressing the Reset button twice before
continuing work.
If modified safety-related parameters are received after run-up has been completed, the
motor starter responds as follows depending on its status:
● Motor OFF in automatic mode
The motor starter accepts the new parameters. The parameters are indicated by the
LEDs' flashing sequence. To activate the parameters, confirm them with the blue button.
The motor cannot be switched on before the parameters are activated.
● Motor ON in automatic mode and in manual local mode
The motor starter rejects the parameters. The "Parameter changes not allowed in motor
ON state" message is issued. As communication is not secure, the motor starter does not
respond to the modified parameters. Depending on the parameterization, entries in data
set "DS92" or diagnostic interrupts are generated. The entries in data set "DS92" are
deleted as soon as the modified parameters are active.
● Manual local mode
The motor starter accepts the new parameters and saves them. As soon as manual local
mode is ended, the parameters are activated and indicated by means of the LEDs'
flashing sequence. Confirm the parameters with the blue button. The motor cannot be
switched on before the parameters are activated.
The motor starter remains in the safe state (STO) until you have confirmed the parameters.
Before you have confirmed the parameters, they can already be read out in data set
"DS203". Data set "DS201" is accepted. A group warning in data set 92 (Page 126) and in
the process image of the inputs is triggered. Moreover, a maintenance alarm, "New safety-
related parameters received" (0x1036), can be generated.
Response to invalid parameterization
If inconsistent or invalid parameterization is detected, the applicable parameters are
discarded. Entries in data set "DS92" or diagnostic interrupts are generated. To narrow down
the invalid parameterization, compare the parameter values from the data sets "DS201" and
"DS203" or "DS202" and "DS204".
Reading back the data sets "DS201" and "DS202" returns the last correctly transferred data
set, even if it is rejected later due to inadmissible content.
Data sets with incorrect lengths are rejected and discarded. The starter continues to operate
with the last valid parameter.
