2 Parameters
2.2 List of parameters
Note: Bit 0 ... 3 only have influence for sensorless vector control, bit 4 only for vector control with encoder. Bit 2 is pre-
assigned depending on p0500.
For bit 2 = 1:
The sensorless vector control is effective down to zero frequency. A change is not made into the open-loop speed
controlled mode.
This operating mode is possible for passive loads. These include applications where the load itself does not generate
any active torque and therefore only acts reactively to the drive torque of the induction motor.
If bit 2 = 1, then bit 3 is automatically set to 1. Manual de-selection is possible and may be sensible if the saturation
characteristic (p1960) was not measured for third-party motors. Generally, for standard SIEMENS motors, the
already pre-assigned (default value) saturation characteristic is adequate.
When the bit is set, the selection of bits 0 and 1 is ignored.
For bit 2 = 0:
If the model feedback is deactivated (p1784 = 0), with bit 2 = 0, then bit 3 is also automatically set to 0.
For bit 5 = 1:
The selection of HF signal injection is only relevant for permanent-magnet synchronous motors (PMSM). Therefore,
activation of bit 5 is only possible outside of motor commissioning (p0010 = 0).
In order to achieve user-friendly configuration of the power unit components in the oversampling mode, when
activated for the first time, initially p1810.3 is set, and then an automatic system boot is initiated. This is only possible
if all of the axes connected to the Control Unit are switched off (refer to the setting conditions for p0009); otherwise, it
is not possible to set the bit.
When deactivating p1750.5, p1810.3 remains unchanged and the system does not boot again.
Therefore, to reverse configure the power unit components from the oversampling mode (after manually deselecting
p1750 bit 5) then initially p1810 bit 3 must be manually deleted and then a manual warm restart initiated.
As an alternative to a warm restart: save the parameters and carry out a POWER ON (switch-off/switch-on).
When the function "safety without encoder" (p9306/p9506) is activated, this setting is not permissible and results in
monitoring errors.
For bit 6 = 1:
The following applies for encoderless vector control of induction motors:
For a blocked motor (see p2175, p2177) the time condition in p1758 is bypassed and a change is not made into
open-loop controlled operation.
The following applies for encoderless vector control of synchronous motors:
For a blocked motor (see p2175, p2177), the speed ramp-function generator is held in open-loop speed controlled
operation, and a change is not made into closed-loop controlled operation.
For bit 7 = 1:
The following applies for encoderless vector control of induction motors:
If the changeover limits are parameterized too low (p1755, p1756), then they are automatically increased to rugged
values by the absolute amount p1749 * p1755.
The effective time condition for changing over into open-controlled operation is obtained from the minimum of p1758
and 0.5 * r0384.
Activation can make sense for applications that demand a high torque at low frequencies and therefore low speed
gradients.
Adequate parameterization must be ensured (p1610, p1611).
