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:
1:
2:
3:
Notice: If the technological application is set to p0500 = 0 ... 3 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 p0500 = 0 and when the calculation is initiated, the following parameters are set:
- p1574 = 10 V
- p1750 bit 2 = 0
- p1802 = 4 (SVM/FLB without overcontrol) (PM240: p1802 = 0, PM260: p1802 = 2)
- p1803 = 106 % (PM260: p1803 = 103 %)
For p0500 = 1 and when the calculation is initiated, the following parameters are set:
- p1574 = 2 V
- p1750 bit 2 = 0
- p1802 = 4 (SVM/FLB without overcontrol) (PM240: p1802 = 0)
- p1803 = 106 % (PM260: p1803 = 103 %)
For p0500 = 2 and when the calculation is initiated, the following parameters are set:
- p1574 = 2 V (for separately-excited synchronous motors: 4 V)
- p1750 bit 2 = 1
- p1802 = 4 (SVM/FLB without overcontrol) (PM240: p1802 = 0)
- p1803 = 106 % (PM260: p1803 = 103 %)
For p0500 = 3 and when the calculation is initiated, the following parameters are set:
- p1574 = 2 V
- p1750 bit 2 = 1
- p1802 = 4 (SVM/FLB without overcontrol) (PM240: p1802 = 0)
- p1803 = 106 % (PM260: p1803 = 103 %)
Re p1750:
The setting of p1750 is only relevant for induction motors.
p1750 bit 2 = 1: Sensorless closed-loop control of induction motors effective up to a frequency of zero.
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.
Re p1802 / p1803:
p1802 and p1803 are only changed, in all cases, if a sine-wave output filter (p0230 = 3, 4) has not been selected.
