FR-E800 E.ECT — Encoder signal loss

CAUSE

Why does it occur?

1. The inverter output is shut off when the encoder signal is shut off under orientation control, encoder feedback control, or Vector control
2. This protective function is not available in the initial status. (This protective function is available for the standard model, the Ethernet model, and the safety communication model.) • Check for the encoder signal loss. • Check that the encoder specification

REMEDY · Step by step

How to fix it?

1. • Remedy the signal loss. • Use an encoder that meets the specifications. • Make connection securely. • Make a switch setting of a Vector control compatible option correctly. • Supply the power to the encoder
2. Alternatively, supply the power to the encoder at the same time when the power is supplied to the inverter
3. If the power is supplied to the encoder after sent to the inverter, check that the
