7.1. Error reaction
Digital intelligent AC servo drives offer the possibility of preselecting
different error reactions for each drive in a drive package. Error reactions
1 and 2 make it possible to complete machining operations on workpieces
even in the event of errors occurring in other drive package axes not
involved in the machining process (e.g. loading axes).
INDRAMAT classifies errors according to:
– Errors causing an error reaction in the entire drive package.
– Errors causing individual drive-specific error reactions.
Errors causing an error reaction in all drives connected up to one power
supply module are:
22 "Motor encoder error"
24 "Overcurrent"
60 "Bridge fuse"
61 "Earth-fault fuse"
67" "Faulty hardware synchronization"
69 "± 15 Volt error"
70 "± 24 Volt error"
71 "± 10 Volt error"
72 "+ 8 Volt error"
73 "Voltage supply driver stage"
(For more details on errors, see Section 9)
Danger through involuntary drive movements!
The errors stated above prevent the drive being stopped under
controlled conditions.
1. The drive affected by the error sends an error signal to the power
supply module.
2. The power supply module cuts the power.
3. The error signal "undervoltage" sent by the power supply module to
the drives is ignored by the unaffected drives. These can then be
brought to a standstill in under normal process conditions via the NC
control. However, stopping under normal process conditions will
depend on the residual energy available in the DC link circuit.
4. The deceleration path can be shortened via the power supply module
by activating the "plug braking" function (see documentation on the
installed power supply module).
