Instruction manual 91/121 V6.3
Autotune mode
Function available only with brushless motor.
Enabling the self-learning function of the brushless motor electrical parameters indicated in the group “Optional param”. Activate this
mode to power drive but without enabling (Green LED RUN off), then you can enable the drive and the measurement phase takes
place (the green LED RUN flashes).
For more information on Autotune mode, see page 54.
Optional Param
Menu group with optional parameters that can be measured automatically by the “Autotune” procedure. If this procedure is not pos -
sible or if the motor parameters are known (provided by the manufacturer), they can be entered manually using the above menu group.
Feedback phase

Displayed only with

degrees
Brushless motor
Set the transducer offset to the motor rotor, if known. This parameter is optional and can be calculated automatically by the “Autot -
une” procedure.
Feedback Direction
With this parameter you can reverse the direction of counting of the transducer connected to the motor. The possible selections are as
follows:
•
NORMAL: The signal coming from the transducer is NOT reversed in direction.
•
REVERSE: The signal from the transducer is reversed in direction.
With a brushless motor this parameter is optional and can be calculated automatically by the “Autotune” procedure; instead for a D.C.
motor this parameter is manually set so as not to generate the “Feedback Fault” alarm (see section 6.4.13 on page 72).
Hall Phase
Minimum Maximum
Units of measure
Displayed only with
-180 °

degrees
Brushless motor with TTL Encoder transducer
Set the offset of the hall sectors relative to the motor rotor, if it is known. This parameter is optional and can be calculated automatic-
ally by the “Autotune” procedure.
Hall Direction
Parameter displayed only with brushless motor with TTL Encoder transducer or brushless Tacho-generator or 10V Tacho-generator.
With this parameter you can reverse the direction of the hall sectors connected to the motor. The possible selections are as follows:
•
NORMAL: The signals of the hall sectors are NOT reversed in direction.
•
REVERSE: The signals in the hall sectors are reversed in direction.
This parameter is optional and can be calculated automatically by the “Autotune” procedure.
Hall inverted
Parameter displayed only with brushless motor with brushless tachometer transducer or 10V Tacho-generator.
With this parameter you can reverse one of the three Hall sectors. Its purpose is to make the hall sectors at 60° compatible with the
specific decoding for the 120° (plus standard) hall sectors. The possible selections are as follows:
•
NO: no hall sensor is to be reversed (hall to 120°).
•
SE1: the hall sensor “SE1” has been reversed (hall at 60°).
•
SE2: the hall sensor “SE2” has been reversed (hall at 60°).
•
SE3: the hall sensor “SE3” has been reversed (hall at 60°).
This parameter is optional and can be calculated automatically by the “Autotune” procedure.
Tacho combin

Brushless Tacho-generator transducer
With this parameter you change the combination of use of the signals measured by the brushless Tacho-generator.
This parameter is optional and can be calculated automatically by the “Autotune” procedure.
Drive Parameters
Menu group to set the main parameters of the drive grouped for faster adjustment. For a normal operating calibration with average
performance it is sufficient to adjust the parameters grouped here.
