error
An error occurred in communication through the encoder link.
XXYYZZZZ
XX = FF[Hex] (fixed)
YY = 00[Hex] Detection of error at motor attached encoder.
01[Hex]: Detection of error at shaft attached encoder.
02[Hex]: Detection of error at separately installed encoder.
03[Hex]: Detection of error at absolute scale.
04[Hex]: Detection of error at sub-slider
ZZZZ = Encoder link status at the detection of error
bit 15 = 1:
Error in the communication with the separately installed
encoder
bit 14 = 1:
Error in the communication with the absolute scale 2
bit 13 = 1:
Error in the communication with the shaft attached
encoder or absolute scale
bit 12 = 1:
Error in the communication with the motor attached
encoder
bit 11 : Undefined
bit 10 = 1 : AT mode send loop error
bit 9 = 1:
Receive IF section data number over error
bit 8: Undefined
bit 7: Undefined
bit 6 = 1 : Modulation code error
bit 5 = 1 : CRC error
bit 4 = 1 : Format error
bit 3 = 1 : Double send error
bit 2 = 1 : Double receive error
bit 1 = 1 : Parity error
bit 0 = 1 : Timeout error
Check the encoder
of the corresponding
axis.
Change the encoder
link cable.
Change the MIV unit.
11
Encoder error
The motor attached encoder failed to detect the position data.
XXYYZZZZ
XX = Error code of encoder
YY = Detailed status of encoder
ZZZZ = Multi-turn position data
If the multi-turn position data exceeded the allowable turn
range:
XX = 0 (fixed)
YY = 1 (fixed)
ZZZZ = Multi-turn position data
Change the motor
attached encoder.
No.
