The '50.XDIAG' Activation of extended diagnostics (Page 170) pa‐
rameter is set to 'On1', 'On2' or 'On3'.
● OFF
● On
Use this parameter to continuously monitor the total strokes covered
by the actuator. A total stroke corresponds to the path from the lower
endstop of the actuator to the upper endstop and back again, in other
words twice the travel. During operation, partial strokes of the ac‐
tuator are added together into total strokes. Monitoring is performed
in three steps. To activate monitoring, set the parameter to 'On'. Sub-
parameters are displayed. Appropriately set the sub-parameters.
The current value is displayed in Diagnostic value '1.STRKS - Num‐
ber of total strokes' (Page 255). The positioner triggers a message
if the current value exceeds one of the three thresholds. This mes‐
sage is only output if threshold 2 or 3 is not exceeded at the same
time.
OFF
1 ... 1.00E8
Use this sub-parameter to set the base limit for the number of total
strokes. Set the base limit in a range from '1' to '1.00E8'.
1.00E6
0.1 ... 40.0
Use this sub-parameter to set the factor for formation of threshold
1. Set the factor in a range from '0.1' to '40.0'. The threshold is the
product of 'L1.LIMIT' and 'L2.FACT1'.
The threshold 1 message is displayed when threshold 1 is excee‐
ded. The process to activate and display this message is described
in the 'XDIAG' parameter.
