Parameters
List of Parameters
p1810 Modulator configuration / Modulator config
Access level: 3
Can be changed: U, T
Min
-
Description: Sets the configuration for the modulator.
Bit field: Bit Signal name
00 Avg value filter for V_lim (only for
Vdc_comp. in modulator)
01 DC link voltage compensation in the current
control
Notice: Bit 1 = 1 can only be set under a pulse inhibit and for r0192.14 = 1.
Note: Bit 00 = 0:
Voltage limitation from the minimum of the DC link voltage (lower ripple in the output current, reduced output volt-
age).
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).
Bit 01 = 0:
DC link voltage compensation in the modulator.
Bit 01 = 1:
DC link voltage compensation in the current control.
p1820[0...n] Reverse the output phase sequence / Outp_ph_seq rev
Access level: 2
Can be changed: C(2), T
Min
0
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:
1:
Note: This setting can only be changed when the pulses are inhibited.
p1825 Converter valve threshold voltage / Threshold voltage
Access level: 4
Can be changed: U, T
Min
0.0 [Vrms]
Description: Sets the threshold voltage drop of the valves (power semiconductor devices) to be compensated.
Note: The value is automatically calculated in the motor data identification routine.
p1828 Compensation valve lockout time phase U / Comp t_lock ph U
Access level: 4
Can be changed: U, T
Min
0.00 [µs]
Description: Sets the valve lockout time to compensate for phase U.
Note: The value is automatically calculated in the motor data identification routine.
