Okuma Alarm-D 4163 MCS Encoder link error
An error occurred in the encoder communication link, disabling the encoder from detecting positioning speed.
Axis name or none (spindle)
XX = FF (fixed)
YY = 00: YY = 00: Error is detected at the motor encoder.
02: Error is detected at the independent position encoder.
03: Error is detected at ABSO SCALE.
ZZZZ= Encoder link error status at the time of error detection.
bit 15 1: Error in communication with a stand-alone encoder
bit 14 1: Error in communication with ABSO SCALE 2
bit 13 1: Error in communication with ABSO SCALE or encoder with shaft
bit 12 1: Error in communication with motor encoder
bit 11 1: Undefined
bit 10 1: Transmission loop error in AT (auto) mode
bit 9 1: Data over error in data receiving part of interface
bit 8 1: Undefined
bit 7 1: Undefined
bit 6 1: Modulation code error
bit 5 1: CRC error
bit 4 1: Format error
bit 3 1: Double transmission error
bit 2 1: Double reception error
bit 1 1: Parity error
bit 0 1: Time-out error
Probable Faulty Locations
– Motor encoder, ABSO SCALE, encoder with shaft, or stand-alone encoder of the problem axis
– Encoder link cables or connectors
– Inverter unit control board
