7.3 IGBT Voltage Output Distortion
The procedure shows an example to compensate the output voltage
distortion due to IGBT voltage drop and its switching characteristics.
Use a 3 channel digital scope + 1 current probe.
In the
INTERFACE / An Out 1
menu, program the Analog output 1:
-
C08.00 - AO 1 src
connected to
Norm speed
variable
On the 21-22 drive terminals (Analog output 1), place channel 1 of the
digital scope to display the motor speed, (see chapter 4.3).
- Connect the current probe on channel C of the digital scope on one of
the motor wires to display the motor current (It's possible to use a
differential probe on XY5/XY4 regulation board test points instead of a
current probe on the output phases).
- Run the motor at 300 rpm.
Go to menu:
REG PARAM / DeadTime
Adjust:
E04.01 - Dead time slope
parameter to match the figure 7.3.1.
