Error Codes of Alarm 300500
Error code 0018H
Error text HOST interrupt
Extension 1 -
Extension 2 -
Explanation An illegal processor interrupt has occurred.
The cause is probably a hardware error on the control module.
Remedy Check the drive bus cable and cable connections. Replace the control module.
Error code 0019H
Error text DSP-NMI (10 V at pin IRQB of the DPS)
Extension 1 -
Extension 2 -
Explanation An illegal processor interrupt has occurred.
The cause is probably a hardware error on the control module.
Remedy Check the drive bus cable and cable connections. Replace the control module.
Error code 001BH
Error text Actual current measurement starting.
Extension 1 0 : Deviation from current 0
1 : Module selection does not match the existing hardware (V 2.6 and higher).
Extension 2 NC drive number
Explanation When the actual current measuring is starting up and during cyclical operation with a
pulse disable, current 0 is expected as the system ensures that no currents can flow.
Deviation from current 0:
The hardware for actual current measurement may be defective.
Module selection does not match the existing hardware:
If a single-axis power section has been addressed as a two-axis power section by the
module selection (software parameterization of power section), this system error is out-
put via actual current measurement because a current > 0 is measured.
Remedy Deviation from current 0:
Replace the control module. Check the cable connections.
Module selection does not match the existing hardware:
− Change software parameterization of power section (two-axis power section -> sin-
gle-axis power section).
− 2. Define axis as inactive or use a two-axis power section.
