(e.g. X with Y).
Motor encoder cables crossed.
Phases connected incorrectly to
motor.
Motor encoder cable is defective.
Incorrect entry in motor table
(rotation direction, no. pole pairs).
Motor defective.
Check the motor cabling.

2688 The 5V power supply of the iTNC is
outside the permissible tolerance
range.
2720 The amplitude of the encoder signal
is too large or the signal for
contamination is active.
44 The amplitude of the encoder signal
is too small or the signal for
contamination is active.
Corrective action
Inform your service agency.
Check the control and cabling of
the pulse release.
Check Uz.
If the power supply is not
regenerative: Is the braking resistor
connected?
If the power supply is regenerative:
Is the energy recovery activated?
Check the grounding and shielding
of the cable.
Exchange the power module.
For P controls: Exchange the
interface card.
Exchange the motor drive control
board.
Inform your service agency.
Check the motor encoder and
leads.
Exchange drive control board.
Inform your service agency.
Check motor and motor cables.
Check the entry in the motor table.
Inform your service agency.
Check the inverter.
Check the motor and cabling.
Check the machine parameters.
Inform your service agency.
Check the amplitude of the
encoder signal.
Check the amplitude of the
encoder signal.
