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: 1: Pumps and fans
3: Pumps and fans, efficiency optimization
Dependency: For p0096 = 2 (Dynamic Drive Control) p0500 cannot be changed.
Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1), "Dynamic Drive Control" (DDC, p0096
= 2)
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 p0500 = 1 and when the calculation is initiated, the following parameters are set:
- p1570 = 100 %
- p1580 = 0 % (no efficiency optimization)
- p1574 = 2 V
- p1750.2 = 0
- p1802 = 9 or 19 (optimized pulse pattern for p0300 = 14)
- p1803 = 106 %
For p0500 = 3 and when the calculation is initiated, the following parameters are set:
- p1570 = 103 % (flux boost for full load)
- p1580 = 100 % (efficiency optimization)
- p1574 = 2 V
- p1750.2 = 1: Encoderless control of the induction motor is effective down to zero frequency.
- p1802 = 9 or 19 (optimized pulse pattern for p0300 = 14)
- p1803 = 106 %
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)
