Does Multiturn IncOder increment turn count when the device is not powered?

No. If the IncOder were to move whilst the power is off, then when power is re-applied the IncOder cannot determine how many revolutions may have been performed. It is a requirement that the IncOder does not move by more than ±1.5 degrees whilst power is off. Multiturn IncOder is an absolute inductive encoder with non-volatile turn count storage. Turn count is stored in this non-volatile memory so that it is retained during “loss of power” events. When power is re-established, the turn count is retrieved and turn counting will continue.
