Danfoss iC7 Series User Manual

Bit
Description
0
Shows that a general problem has been detected, see parameter 9.1.9 Encoder Status Word for details.
2
No valid position from the connected absolute encoder. Can be caused by supply voltage, wiring issues, electrical noise, or
defective encoder. Check supply voltage, clock and data signals. Reducing clock/baud rate might help especially in case of
long encoder cable.
3
No valid position from the connected absolute encoder. Can be caused by supply voltage, wiring issues, electrical noise, or
defective encoder. Check supply voltage, clock and data signals. Reducing clock/baud rate might help especially in case of
long encoder cable.
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.
8
Absolute encoder or resolver signal error. Check wiring and encoder.
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.
10
No valid position from the connected absolute encoder. Can be caused by supply voltage, wiring issues, electrical noise, or
defective encoder. Check supply voltage, clock and data signals. Reducing clock/baud rate might help especially in case of
long encoder cable.
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
least 0.875 V: U
A
2
+ U
B

.
15
Shows that no zero pulse has been detected after moving a full rotation. Check wiring and encoder.
