DOK-INDRV*-GEN-**VRS**-WA01-EN-P
C0120 Error when reading encoder data => motor encoder
Supported by Firmware Variant:
FWA-INDRV*-
MPH02
VRS-MS
FWA-INDRV*-
MPB02
VRS-MS
FWA-INDRV*-
MPD02
VRS-MS
During the transition check from communication phase
2 to
communication phase 3 (C0100) an error during the reading of the
encoder data from the data memory of the motor encoder was detected.
Note:
Measuring systems with their own data memory are DSF/HSF
and resolvers, as well as measuring systems with EnDat
interface (Heidenhain company) and HIPERFACE
interface
(Stegmann company).
Cause
Remedy
Measuring system cable defective
Check measuring system cable
Measuring system defective
Replace measuring system
Encoder interface card defective
Replace encoder interface card

During the transition check from communication phase
2 to
communication phase
3 (C0100) an error with regard to the
parameterization of the motor encoder hardware was detected.
Cause
Remedy
Parameterization
P-0-0074, Encoder type 1 (motor
encoder)
does not match interface card (e.g. EN1
with EnDat encoder)
Check whether parameterized encoder type matches
interface card that has been plugged in
In the case of "current control with motor encoder"
(see
P-0-0045, Control word of current
controller
), "operation without encoder" was
detected to have been set in
P-0-0074, Encoder
type 1 (motor encoder)
Enter value appropriate for motor encoder in
P-0-0074,
Encoder type 1 (motor encoder)
Parameterization in
P-0-0077, Assignment motor
encoder->optional slot
is incorrect
Correct assignment of motor encoder and optional slot
in parameter
P-0-0077, Assignment motor
encoder->optional slot
