(5) Checking gate drive circuit of IGBT PCB(MCC-1252-04)
a. Measuring gate drive voltage
Measuring part Voltage
U phase
V phase
W phase
XYZ phase
b. Checking the signal to IGBT
Pull out the connectors on IGBT PCB CN22, CN23, CN24 and CN25, check the voltage value of eachindicator.
Check all items when it is in Thermo ON and Thermo OFF.
Measuring part Voltage
Thermo On
U phase CN22
V phase CN23
W phase CN24
X phase CN25
Y phase CN12
Z phase CN12
Thermo OFF
U phase CN22
V phase CN23
W phase CN24
X phase CN25
Y phase CN25
Z phase CN25
The voltage values in above positions must be consistent and within the range of the table.
