0018H
HOST interrupt
-
-
An illegal processor interrupt has occurred.
The cause is probably a hardware error on the control module.
Check the drive bus cable and cable connections. Replace the control module.
0019H
DSP-NMI (10 V at pin IRQB of the DPS)
-
-
An illegal processor interrupt has occurred.
The cause is probably a hardware error on the control module.
Check the drive bus cable and cable connections. Replace the control module.
001BH
Actual current measurement starting.
0: Deviation from current 0
1: Module selection does not match the existing hardware (V 2.6 and higher).
NC drive number
When actual current measuring is starting up and during cyclic operation with a pulse dis-
able, a zero current is expected, as the system ensures that no currents can flow.
Deviation from zero current:
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 output
via actual current measurement because a current > 0 is measured.
Deviation from current 0:
Replace the control module. Check cable connections.
Module selection does not match the existing hardware:
- Change software parameterization of power section (two-axis power section -> single-
axis power section).
- 2. Deactivate axis or use a two-axis power section.
0020H
Second axis 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).
