Bit Description
7 An absolute encoder has not yet been configured or encoder initialization is in progress. This is just a status bit showing
that the encoder is not yet ready to provide valid position information.
9 Shows that invalid data has been received on the absolute channel. Check wiring and encoder, might be caused by electri-
cal noise disturbing the data transmission.
12 Shows that the absolute and incremental tracks count opposite on an absolute encoder with incremental track. Invert the
incremental direction by swapping A and B.
13 Shows a mismatch between the incremental track and the absolute track or the zero pulse. Indicates that the set incremen-
tal resolution is wrong.
14 SinCos encoder signal error - indicates too low signal voltage. The combined voltage on A and B at standstill must be at
2
least 0.875 V: U + U
A B
15 Shows that no zero pulse has been detected after moving a full rotation. Check wiring and encoder.
P 9.1.9 Encoder Status Word
Description: Shows an overall status indication represented in the following bits: Bit 0: Plug detect; Bit 1: Encoder supply; Bit 2:
Resolver; Bit 3: Short protect; Bit 15: Encoder data not ready.
Default Value : NA
Unit: -
Following are the bits and description.
Bit Description
0 Shows that the Plug Detect connection between pin 11 and 13 is interrupted. Check the connection and that the plug is
correctly inserted.
1 Shows that the encoder power supply is overloaded. Check the load connected to pin 7 and 9.
2 Shows that the resolver signal is missing or invalid. Check the resolver signal, might be a wiring problem or a defective
resolver.
3 Shows that a short circuit has been detected on one or more of the 4 tracks A, B, Z and D. Check the wiring.
15 Shows that no valid data has been received from a connected absolute encoder. Check that the encoder configuration
matches the encoder specifications. Next check the wiring and the encoder.

Description: Select the required configuration of the interface consisting of 4 tracks A, B, Z and D. The interface offers various com-
binations of 1 or 2 devices.
