- Choice of the proportional gain for zero speed:
The P-gain corresponds to
Spd=0 P gain
Enable spd=0 P
= Enabled
The P-gain corresponds to the normal P-gain
Enable spd=0 P
= Disabled
- The P-gain at a zero speed is set via
Spd=0 P gain
, when
Enable spd=0 P
is enabled.
- The intervention threshold for the recognition of zero speed is determined with
Ref 0 level
. It is expressed
in the dimension set by the factor function.
Adaptive of the speed regulator
n

!
The adaptive of the speed regulator is factory set as disabled. It must be used only when the
gain of the speed regulator has to get higher than the speed range or it has to be replaced with
another unit. As for the interaction among the parameters see section 6.13.2, “Adaptive spd
reg”.
- Enable of the adaptive with a blocked drive.
Enable spd adap
= Enabled. In this way the settings of
Speed
P
and
Speed I
are disabled.
- Determine on the basis of which unit the gain of the speed regulator has to be changed. It normally depends
on the speed (
Select adap type
= Speed).
- If the gain has to be changed on the basis of another unit, set
Select adap type
= Adap reference. This unit is
connected to the device as an analog value via an analog input. For this reason the
Adap reference
variable
must be assigned to an analog input (see in the following pages the configuration of the analog inputs).
The other possibility is to insert
Adap reference
via the serial interface or a Bus. In this case the insertion
via the terminal strip is not necessary.
- Entering
Adap speed 1
and
Adap speed 2
three different speed ranges are available with several gains.
Value expressed as a percentage of
Speed base value
and respectively of the max value of
Adap reference
.
- With
Select adap type
= Speed: the optimization is carried out as described for the “Speed regulator”. To
this purpose the following points must be taken into consideration:
- Enter with
Gen offset
a value which is at the beginning of the range to be optimized but which at the
same time is outside the range set with
Adap joint XX
.
- Enter with
Gen amplitude
the step, so that the speed remains inside the range to be optimized.
- The optimization is carried out separately for each range and the paramters of the regulator are set for
each range with
Adap P gain XX
and
Adap I gain XX
.
- After the optimization of the different phases look over the whole speed range.
- By changing the value of
Adap joint XX
it is possible to reduce the instabilities present in the transients
during the changes from one range to the other. Increasing the values the transients are slighter.
- With
Select adap type
= Adap reference: the optimization depends on the system and it is impossible to
state here the general information needed.
- When the speed zero logic is disabled (factory setting) with a blocked drive the gains of the speed regulator
are active. These are set via
Adap P gain 1
and
Adap I gain 1
. When the speed zero logic is enabled, the
values set for a motor at a stop are valid.
