0021H
Two active axes: At least one is defined as single-axis module by SERVO.
-
-
The NC has attempted to activate the second axis on a single-axis module, possible com-
munication failures on the drive bus or control module defective.
Replace the control module. Check cable connections, perform remedial measures
(check shielding or ground connection).
0022H
PCU-ASIC for motor measurement systems missing for at least one axis.
-
-
The motor measuring system is either not fitted or is defective for at least one axis of the
drive module. As the configuration of the measuring systems is detected by the NC and
communicated to the drive, communication failures on the drive bus can also cause this
error.
Replace the control module. Check cable connections, perform remedial measures
(check shielding or ground connection).
0023H
Incorrect IPU_submodule is plugged into the motor measurement system.
Read K1C register of the relevant PCU ASIC.
NC drive number
The motor measuring system has a motor encoder with a voltage output. A corresponding
IPU submodule with a voltage input is required. An unexpected submodule has been
detected.
Replace the control module. Check cable connections, perform remedial measures
(check shielding or ground connection).
0024H
Illegal physical axis number
-
-
An illegal internal axis number was detected during software processing (only 0 or 1 is
permitted in the case of 2-axis modules).
Possible causes: Defective control module, EMC interference
Replace the control module. Check cable connections, perform remedial measures
(check shielding or ground connection).
0025H
Illegal physical axis number
-
-
An illegal internal physical axis number was detected during software processing.
Possible causes: Defective control module, EMC interference
Replace the control module. Check cable connections, perform remedial measures
(check shielding or ground connection).
