Ctr.14 : Autotune
• During the autotune phase, brake control is
disabled.
• Measurements taken when Ctr.14 = Running must
be performed with the motor uncoupled since the drive
drives the motor at 2/3 of its rated speed. This autotune
is necessary only in closed loop operating mode ( ).
Make sure that this operation does not present any safety
risks, and that the motor is stopped before the autotune
procedure.
• After modifying the motor parameters, repeat
autotuning.
None (#):
No autotune performed.
At the end of an autotune procedure, Ctr.14 reverts to None.
Stationary: Motor data completed
- If Ctr.02 = Induction motor in open loop mode or Induction
motor in vector control mode: The stator resistance and
voltage offset respectively are measured and stored.
- If Ctr.02 = PM motor (Servo) in vector control mode: The
stator resistance and voltage offset respectively are
measured and stored.
The stator inductance is measured but not stored. An
alarm is generated if its value is very different from the
value entered in Mtr.08 . The current loop is automatically
set.
- Other Ctr.02 modes: no action.
Procedure:
- Ensure that the motor parameters have been configured ( Mtr
«Motor nameplate»
menu) and that the motor is stopped.
- Enable the drive.
- Give a run command.
- Wait until the procedure ends.
- Disable the drive and remove the run command.
The motor is then ready to operate normally.
Parameter Ctr.14 reverts to «None» as soon as autotuning
is complete.
Rotating: motor data incompleted
- If Ctr.02 = Induction motor in open loop mode: Procedure
not compatible with this control mode.
- If Ctr.02 = Induction motor in vector control mode: The
stator resistance and voltage offset are measured and
stored. The Transient inductance / Ld Mtr.08 and total
inductance «Ls» are also measured and stored. The
power factor Mtr.05 is automatically updated.
- If Ctr.02 = PM motor (Servo) in vector control mode: The
stator resistance and voltage offset are measured and
stored. The Transient inductance / Ld Mtr.08 and no-load
EMF Mtr.09 are measured and stored. An alarm is
generated if their values are very different from the values
entered in Mtr.08 and Mtr.09 .
- Other Ctr.02 modes: no action.
Procedure:
- Ensure that the motor parameters have been configured and
that the motor is stopped.
- Enable the drive.
- If the drive is undersized in relation to the motor power, reduce
the current limit Ctr.04 in order to avoid causing the drive to
trip.
- Give a run command. The motor is driven, then performs a
freewheel stop when autotuning is complete.
- Wait until the procedure ends.
- Disable the drive and remove the run command.
The motor is then ready to operate normally.
Parameter Ctr.14 reverts to «None» as soon as autotuning
is complete.
Encoder offset measure/rotor parking:
This mode is only active if Mtr.10 is set to «UVW only»,
«Incremental UVW», «Hall effect sensor» or «Resolver». In
this mode, the motor runs at very low speed so that the encoder
offset can be measured. This offset is automatically stored in
Mtr.13 .
Encoder offset measure/signal injection:
Reserved for the «Advanced» menu.
CAUTION:
If a stop command is given before the end of the autotune
phase, an «Autotune» trip is generated.
