Interactions with the various operating modes

PROFIenergy is influenced by the operating modes (Page 24) as follows:
• The energy saving mode only works in the "Automatic" mode.
When the 3RW5 soft starter in the "Manual operation bus" or "Manual operation local" modes
receives a command to switch to energy saving mode or operating mode , it will only switch
to the corresponding mode after switching to "Automatic" mode.
• The "Manual operation bus" and "Manual operation local" modes are not influenced by
PROFIenergy.
You can also switch to the "Manual operation bus" and "Manual operation local" operating
modes and control the 3RW5 soft starter manually. When you switch back to "Automatic"
mode, the 3RW5 soft starter will respond according to the last command.
• Cyclic and acyclic data transmission (e.g. process images, data records, diagnostics, alarms)
to and from the 3RW5 soft starter are still possible.

Commands for PE measured value function

Efficient energy management requires the provision of measured values for energy. The
PROFIenergy specification offers various measured values from which to choose, each of which
is assigned a measured value ID.

Description
Time required for the 3RW5 soft starter to enter energy saving
mode. If present and the 3RW5 soft starter was in the ON state, a
parameterized deceleration ramp time is added.
This time is as follows for 3RW5 soft starters: 200 ms + deceleration
ramp time
The minimum time that the 3RW5 soft starter will or should remain
in energy saving mode.
This time is as follows for 3RW5 soft starters: 0 ms
Time until the 3RW5 soft starter returns to operating mode.
This time is as follows for 3RW5 soft starters: 0 ms
Device-specific minimum pause time.
After a minimum pause time t
switches to energy saving mode.
t = t + t + t
