2.2 List of parameters
Description:
Displays the effective modulator mode.
Value:
1:
Flat top modulation (FLB)
2:
Space vector modulation (SVM)
9:
Optimized pulse pattern
Description:
Sets the configuration for the modulator.
Notice:
Bit 1 = 1 can only be set under a pulse inhibit and for r0192.14 = 1.
Note:
For bit 00 = 0:
Voltage limitation from the minimum of the DC link voltage (lower ripple in the output current, reduced output
voltage).
For bit 00 = 1:
Voltage limitation from averaged DC link voltage (higher output voltage with increased ripple in the output current).
The selection is only valid if the DC link compensation is not performed in the Control Unit (bit 1 = 0).
For bit 01 = 0:
DC link voltage compensation in the modulator.
For bit 01 = 1:
DC link voltage compensation in the current control.
Description:
Sets the phase sequence reversal for the motor without setpoint change.
If the motor does not rotate in the required direction, then the output phase sequence can be reversed using this
parameter. This means that the direction of the motor is reversed without the setpoint being changed.
Value:
0:
OFF
1:
ON
Caution:
For operation with encoder, if the output phase sequence is changed, under certain circumstances it may be
necessary to change the direction of rotation for the encoder (see p0410).
The encoder polarity is also checked for the rotating measurement (see p1959).
Note:
This setting can only be changed when the pulses are inhibited.
