Monitoring The Number Of Changes In Direction "O._Dchg - Siemens 6DR50 Series Operating Instructions Manual

L2.FACT1 - Factor 1
Use this sub-parameter to set the factor for the formation of limit threshold 1. Set the factor in
a range from "0.1" to "40.0". The limit threshold is the product of "L1.LIMIT" and "L2.FACT1".
The threshold 1 error message is displayed when the limit threshold 1 is exceeded. The
procedure to activate and display this error message is described in the "XDIAG" parameter.
The factory setting is "1.0".
L3.FACT2 - Factor 2
Use this sub-parameter to set the factor for the formation of limit threshold 2. Set the factor in
a range from "0.1" to "40.0". The limit threshold is the product of "L1.LIMIT" and "L3.FACT2".
The threshold 2 error message is displayed when the limit threshold 2 is exceeded. The
procedure to activate and display this error message is described in the "XDIAG" parameter.
The factory setting is "2.0".
L4.FACT3 - Factor 3
Use this sub-parameter to set the factor for the formation of limit threshold 3. Set the factor in
a range from "0.1" to "40.0". The limit threshold is the product of "L1.LIMIT" and "L4.FACT3".
The threshold 3 error message is displayed when the limit threshold 3 is exceeded. The
procedure to activate and display this error message is described in the "XDIAG" parameter.
The factory setting is "5.0".

Monitoring the number of changes in direction "O._DCHG"

O. DCHG - Monitoring the number of changes in direction
Use this parameter to continuously monitor the number of changes in direction of the
actuator beyond the deadband.
Configure the following settings to activate the function:
1. Set the "O. DCHG" parameter to "On". Sub-parameters are displayed. Monitoring is
activated.
2. Set the suitable parameter values in sub-parameters. The setting options available in
sub-parameters are described below.
The current value is displayed in the "2 CHDIR" diagnostics parameter. The positioner
triggers a fault message if the current value exceeds a limit threshold.
The factory setting is "OFF".
