"Measured value function" command
Measured values for energy need to be supplied for efficient energy management. The
PROFIenergy specification offers various measured values from which to choose, each of
which is assigned a measured value ID. The ET 200SP motor starter supports the
instantaneous values of the phase current and the mean value of the phase currents as
measured values.
The measured values are uniquely identified by IDs. The following measured value IDs 7, 8,
9, and 33 are supported:
● ID = 7: Current rms value of the phase current a (L1)
● ID = 8: Current rms value of the phase current b (L2)
● ID = 9: Current rms value of the phase current c (L3)
● ID = 33: Mean value of the three phase currents (a+b+c)/3
The current values are transferred with the following tolerances:
● Domain = 0x03 → IEC 61557-12
● Class = 0x0B → 5 %
The result is that the measured values are transferred with an accuracy of 5 % relative to the
maximum configurable rated operational current I

Time_to_Pause
Time_min_length_of_stay
Time_to_operate
Time_min_Pause
Time the starter requires in order to change to energy
saving mode. With the ET 200SP motor starter, this time is
always 100 ms.
Minimum time that the device spends or should spend in
saving mode.
For the ET 200SP motor starter: 150 ms
Time that will elapse before the starter changes back to the
operating state.
For the ET 200SP motor starter: 100 ms (due to startup
sequence)
Time that is compared with t
with the "Start_Pause" command to the motor starter);
if t ≥ t , the device switches to saving mode.
