FR-A800 E.ECA — Encoder signal loss for orientation
Trip — immediate stop
CAUSE
Why does it occur?
- The inverter output is shut off when the machine end encoder signal is shut off during machine end orientation control under Vector control
- This protective function is not available in the initial status. • Check for the encoder signal loss. • Check that the encoder specifications are correct. • Ch
REMEDY · Step by step
How to fix it?
- • 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. (Refer to page 89.) • Supply the power to the encoder
- Alternatively, supply the power to the encoder at the same time as to
Do not reset repeatedly before identifying the cause. Repeated resets while ignoring a trip/alarm can cause secondary damage (IGBT failure, motor winding damage, etc.).
