2.2 List of parameters
For p1750:
The setting of p1750 is only relevant for induction motors.
p1750.2 = 1: Encoderless control of the induction motor is effective down to zero frequency.
This operating mode is possible for passive loads. These include applications where the load does not generate
regenerative torque when breaking away and the motor comes to a standstill (zero speed) itself when the pulses are
inhibited.
For p1802 / p1803:
p1802 and p1803 are only changed, in all cases, if a sine-wave output filter (p0230 = 3, 4) has not been selected.
Description: Sets the technology application.
The parameter influences the calculation of open-loop and closed-loop control parameters that is e.g. initiated using
p0340 = 5.
Value: 0: Constant load (linear characteristic)
1: Speed-dependent load (parabolic characteristic)
Dependency: Not visible with application class: "Dynamic Drive Control" (DDC, p0096 = 2)
Refer to: p1300
Notice: If the technological application is set to p0501 = 0, 1 during commissioning (p0010 = 1, 5, 30), the operating mode
(p1300) is pre-set accordingly.
Note: The calculation of parameters dependent on the technology application can be called up as follows:
- when exiting quick commissioning using p3900 > 0
- when writing p0340 = 1, 3, 5
For p0501 = 0, 1 and when the calculation is initiated, the following parameters are set:
- p1802 = 0
- p1803 = 106 %
- p3855.0 = 1 (DC quantity control on)
For p1802 / p1803:
These parameters are only changed, in all cases, if a sine-wave output filter (p0230 = 3, 4) has not been selected.
Description: Sets the technology application for dynamic applications (p0096 = 2).
The parameter influences the calculation of open-loop and closed-loop control parameters that is e.g. initiated using
p0340 or p3900.
Value: 0: Standard drive (e.g. pumps, fans)
1: Dynamic starting or reversing
5: Heavy-duty starting (e.g. extruders, compressors)
Dependency: The calculation of parameters dependent on the technology application can be called up as follows:
- when exiting quick commissioning using p3900 > 0
- when writing p0340 = 1, 3 or 5
Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Refer to: p1610, p1750
