3 = Software modulator 3
Unsymmetrical BusClamb in which one switch always conducts 120 degrees to negative
DC-rail to reduce switching losses. However, upper and lower switches are unevenly
loaded and the spectrum is wide.
4 = Software modulator 4:
Pure sinewave, sinusoidal modulator without harmonic injection. Dedicated to be used in
back to back test benches etc. to avoid circulating third harmonic current. Drawback is
that required DC voltage is 15% higher compared to other modulator types.
P2.10.3 Control Options ID1084
These parameter functions are dependent of Vacon Marine application version.
B01 = Disable open loop power limit function
B06 = Activate Closed Loop type speed limit function in Open Loop
B07 = Disables switching frequency decrease due to drive temperature rise
B08 = Disable Encoder fault when brake is closed
B12 = Disable Process Data locking function when Profibus communication fails. When
using Profibus, an occurring communication fault will lock the process data to
previous values. This bit will disable the locking of process data forcing the
values to zero. NOTE: This bit can only be used with Profibus.
B13 = Disable only acceleration when using DI Acc/Dec prohibit function
P2.10.4 Control Options 2 ID1798
These parameter functions are dependent of Vacon Marine application version.
B10 =
P2.10.5 Advanced Options 1 ID1560
B00 = Disable Synchronous modulation
B01 = Use encoder information to slip compensation in Open Loop Speed control
B02 = Disable encoder fault
B03 = Disable slip compensation for reverse direction
B06 = Enable synchronous symmetrical modulation
B07 = Automatically handled by application logic.
B15 = Cosphii = 1 control. This controls the motor reactive power to zero. Possible to
use only with PMS motors in closed loop control.
P2.10.6 Advanced Options 2 ID1561
B00 = Sensorless control for PMS motors. This is an open loop control but uses the
same control system than the normal closed loop control. Calculations try to
estimate the encoder speed instead of using the encoder signal. This mode has
speed and torque range limitations and therefore application limitations. A lower
speed controller gain may be required to gain stability. Useful for generator
applications.
B04 = Enable Start Positioning damping active if PMSM
B08 = Current optimization for PMS motor. This function activates the current
optimization for PMSM motor based on torque calculation and motor parameters.
When activated, the optimization starts after 13 % of the motor nominal speed
