- Via the
Set flux / if
parameter (FLUX REGULATION menu) the calculation of the curve parameters will
be carried out. Enter this parameter then press ENT to execute the calculation.
The procedure requires a few seconds.
- Set the operating mode of the field control (
Constant current / Voltage control
), set the value of
Flux
current max
at 100% and save the parameters.
- Changing of
Max out voltage
or
Motor nom flux
need a new curve tuning.
Speed-up function
With loads having a high moment of inertia it is possible to check the jumps during the speed changes. They can
be reduced using the function “Speed-up”. The figures 5.3.7.3 and 5.3.7.4 show the influence of this function.
Figure 5.3.7.3: Above: Actual spd; Below: Motor current jumps with the speed
changes due to a high moment of inertia. The function Speed-up is not active.
Figure 5.3.7.4: Above: Actual spd; Below: Motor current. The same drive with
Speed -up function active.
Parameters used in the example:
Speed up base
14 ms
Speed up gain
50 %
Speed up filter
20 ms
Setting of the speed zero logic
- The speed zero logic is factory set as disabled. See section 6.7.2, “Speed zero logic”, for a description of
the drive behavior.
- Disable of the I-section of the speed regulator with n=0:
I-section disabled:
Enable spd=0
I = Enabled
I-section enabled:
Enable spd=0 I
= Disabled
n
ote
!
When the motor is at a stop, it is possible to avoid the creep of the drive disabling the I sec
-
tion. In this case when the motor is at a stop, it can not receive any load and therefore this
function is not suitable for all applications!
- Suppression of the P-gain set via
Spd=0 P gain
:
- If the reference is above
Ref 0 level
:
Enable spd=0 R
= Enabled
- If the ref.and/or the reaction are above
Ref 0 level
:
Enable spd=0 R
= Disabled
n
ote
!
Enable spd=0 R
is active only when
Enable spd=0 P
is enabled.
