Sd7

What does 087 mean?

An initialization error occurred at the absolute value encoder at X8, or the encoder electronics are defective. This can result from a loose cable, an open circuit, an incorrect encoder type, or failure during rotor position adjustment.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Check the absolute value encoder for correct function.

2. 4

   Set the voltage supply via parameter C0421 to 8.0 V.

3. 5

   If a non-Stegmann encoder is connected, replace it with a compatible Stegmann encoder.

4. 6

   If a rotor position adjustment failed (C0095 = 1), repeat the adjustment after a TRIP reset and with controller enable.
