Error code 0022H
Error text PCU-ASIC for motor measurement systems missing for at least one axis.
Extension 1 -
Extension 2 -
Explanation 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.
Remedy Replace the control module. Check cable connections, perform remedial measures
(check shielding or ground connection).
Error code 0023H
Error text Incorrect IPU_submodule is plugged into the motor measurement system.
Extension 1 Read K1C register of the relevant PCU ASIC.
Extension 2 NC drive number
Explanation The motor measuring system has a motor encoder with a voltage output. A correspond-
ing IPU submodule with a voltage input is required. An unexpected submodule has been
detected.
Remedy Replace the control module. Check cable connections, perform remedial measures
(check shielding or ground connection).
Error code 0024H
Error text Illegal physical axis number
Extension 1 Read K1C register of the relevant PCU ASIC.
Extension 2 NC drive number
Explanation 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
Remedy Replace the control module. Check cable connections, perform remedial measures
(check shielding or ground connection).
Error code 0025H
