423 U1 voltage
(U1 VOLTAGE)
Value:
0.0 - 999.0 V
Function:
Parameters 423-428 are used when in parameter
101Torque characteristic a selection has been made
of Special motor characteristic [8]. It is possible to
determine a U/f characteristic on the basis of four
definable voltages and three frequencies. The voltage
at 0 Hz is set in parameter 133 Start voltage.
Description of choice:
Set the output voltage (U1) that is to match the first
output frequency (F1), parameter 424 F1 frequency.
424 F1 frequency
(F1 FREQUENCY)
Value:
0.0 - par. 426 F2 frequency
Function:
See parameter 423 U1 voltage .
Description of choice:
Set the output frequency (F1) that is to match the first
output voltage (U1), parameter 423 U1 voltage .
425 U2 voltage
(U2 VOLTAGE)
Value:
0.0 - 999.0 V
Function:
See parameter 423 U1 voltage.
