Type 16 Bit Volatile
This parameter shows the state of the signals from the position feedback device as given in the table below. This parameter is intended as a
debugging aid.
Device Type (mm.038): AB

Device Type (mm.038): SMART-ABS, Sankyo
The only signal connection between the drive and the encoder is the communications link which changes too fast to be viewed in a parameter. To
assist with debugging this parameter shows the error status byte from the encoder. The tables below show the meaning of each bit.
SMART-ABS
Bit Meaning
0 Over-speed
1 Low resolution
2 Counting error
3 Counter overflow
4 Encoder temperature
5 Multi-turn error
6 Low battery
Battery alarm. The battery is below the allowed threshold while the encoder
7
is powered up.
Bits 0 to 7 are being updated. If this bit is zero then Bits 0 to 7 show the
8
value the last time the data was read from the encoder.
