Example 3: Activation If The Selection Is Changed (Only If The Inverter Is Disabled) - Lenze i55AE125B Manual

14.9.3

Example 3: Activation if the selection is changed (only if the inverter is disabled)

Activation method 0x4046 (P755.00)
Switches S3 and S4 serve to select the parameter set (see the following table). At the same
•
time, the change-over is activated by a status change of the selection inputs.
Change-over is only possible if the motor is not started (switch S1 open).
•
Switch S2 ("Load parameter set") is ignored in this configuration.
