Switch−off and switch−on thresholds
ƒ The switch−off threshold defines the voltage level of the DC−bus voltage, at which
the pulse inhibit is activated.
ƒ The switch−off and switch−on thresholds dependent on C0173 can be gathered from
the following table:

Tip!
If undervoltage is existent for more that 3 s, or if mains connection is carried
out, an entry into the fault memory is effected.
ƒ This operational mode can occur if the control module is fed via the
terminals X6/+24 and X6/GND by means of an external supply and the
mains are disconnected.
ƒ If there is no undervoltage anymore (mains are reconnected again), the
entry in the fault memory is not continued, but deleted. This case does not
describe an error, but a state of the drive controller.
Undervoltages of less than 3 s are interpreted as a fault (e. g. mains fault) and
are entered into the fault memory. In this case, the fault memory is updated.
