4 Quick-start guide
The checkbox Motor without commutating generator must be ticked for all drives in which
the connected angle encoder does not supply any commutation signals, e.g. in the case of
linear motors. For a correct commutation of the motor, there must be a valid commutation
position after the servo is switched on and before it is enabled for the first time. For this
purpose, the encoder angle referred to 1 revolution must be known. This is not the case for
incremental angle encoder systems, for example. They require additional measures for
determining the commutation position. The checkbox must also be ticked if the motor
includes a rotary encoder that does not supply any commutation signals.
The selection field Further settings depends on the type of application:
Rotatory The button Gearbox display units opens the menu Display units where you
can enter values for your gear (see section 4.4.2 Configuration of the
display unit on page 45).
The button Rotary axis allows you to set a positioning range and to specify
the behavior of the interpolator when positioning in this range.
Translatory The button Feed constant display units opens the menu Display units
where you can enter values for your gear (see section 4.4.2 Configuration of
the display unit on page 45).
The field displayed in light blue shows the display units that are currently used. The button
Settings can also be used to access the Display units menu (see section 7.3 Display units
on page 126).
The tab Extension is where special settings for motors without commutation signals can
be performed.
Risk of damage to the servo drive
If the settings are not ideal, a successful automatic determination of the commutation
position may no longer be possible.
This is why only experts should perform these settings. If this is not possible, they
should only be performed after consultation!
In general, the following types of angle encoders do not require a determination of the
commutation position:
l
Resolvers
l
EnDat
l
Hiperface/Hiperface DSL
l
Analogue encoders with a Z1 track (e.g. ERN1387)
l
Angle encoders with Hall support (block commutation)
