5024 DIVISION_LIN_SCALE
Linear scale graduations
Unit: Default:
nm 20000
5021 ENC_ABS_TURNS_MOTOR
Multi-turn resolution, absolute encoder, motor
Unit: Default:

5023 ENC_ABS_DIAGNOSIS_MOTOR
Diagnostic bits of absolute value encoder, measuring system
Bit 0=1: "Lighting failed"
Bit 1=1: "Signal amplitude too small"
Bit 2=1: "Faulty code connection"
Bit 3=1: "Overvoltage"
Bit 4=1: "Undervoltage"
Bit 5=1: "Overcurrent"
Bit 6=1: "Battery change necessary"
Bit 7=1: "Control check error"
Bit 8=1: "EnDat encoder cannot be used"
Bit 9=1: CDtrack on encoder ERN1387 defective
Bit 10=1: "Protocol cannot be interrupted"
Bit 11=1: "SSI level on data line detected"
Bit 12=1: "TIMEOUT reading measured values"
Bit 13=1: "CRC error"
Bit 14=1: SSI encoder returned alarm
Bit 15=1: "Encoder faulty"

Unit: Default:
HEX 0
4-142
Minimum: Maximum:
1000 (0) 5000000
The standard parameterizing machine data provided support only linear mea-
suring systems. ROD encoders must be converted by the user, i.e. the distance
traversed by the drive between two (coarse) increments must be entered. Value
0 is automatically entered if MD 5011 bit 4 is set to 0 (no linear measuring sys-
tem).
Rotary absolute value encoders cannot be implemented until software version
HLA 01.01.11 and beyond
Minimum: Maximum:
0000 65535
Number of displayable revolutions of absolute value encoder in motor measur-
ing system. The value is read-only.
Minimum: Maximum:
0000 65535
Resolution of motor absolute value encoder in measuring pulses per revolution.
The value is read-only.
Minimum: Maximum:
0 BFFF
