The proof-test is to be performed in 4 steps:
Step nr1 Drive is working with motor torque applied to motor.
This condition is obtained by energizing both STO input signals (ENABLE-A and ENABLE-B)
and by the transmission of PWM commands from Microcontroller to the IGBT Drivers.
WARNING:
Speed and torque applied during this step need to be compliant with acceptable working
conditions of the application where the drive is installed.
Step nr1
partial
result Test Result PASS: Diagnostic LED
“PWM Enable” L2 is LIGHT ON.
If all buffer enable signals are at the right logic level and all related components are correctly
working, then the Diagnostic LED
“PWM Enable” L2 is LIGHT ON.
Test Result FAIL: Diagnostic LED
“PWM Enable” L2 is LIGHT OFF.
If at least one buffer enable signals is not at the right logic level or at least one of the related
components are NOT correctly working, then the Diagnostic LED
“PWM Enable” L2 is LIGHT
OFF.
Step nr2 Activation of the STO function, so no motor torque is applied to motor.
This condition is obtained by de-energizing only one of the STO input signals (ENABLE-A).
Step nr2
partial
result Test Result PASS: Diagnostic LED
“PWM Enable” L2 is LIGHT OFF.
If the buffer Enable signal logic level configuration is correct and all related components are
correctly working, then the Diagnostic LED
“PWM Enable” L2 is LIGHT OFF.
Test Result FAIL: Diagnostic LED
“PWM Enable” L2 is LIGHT ON.
If the buffer Enable signal logic level configuration is not correct or at least one of the related
components are NOT correctly working, then the Diagnostic LED
“PWM Enable” L2 remain
LIGHT ON.
Step nr3 Drive is working again with motor torque applied to motor.
This condition is obtained by energizing again the STO input signal opened during Step nr2
(ENABLE-A) and transmission of PWM commands from Microcontroller to the IGBT Drivers.
WARNING:
Speed and torque applied during this step need to be compliant with acceptable working
conditions of the application where the drive is installed.
Step nr3
partial
result Test Result PASS: Diagnostic LED
“PWM Enable” L2 is LIGHT ON.
Same as Step nr1.
Test Result FAIL: Diagnostic LED
“PWM Enable” L2 is LIGHT OFF.
Same as Step nr1.
Step nr4 Activation of STO function, so no motor torque is applied to motor.
This condition is obtained by de-energizing the other STO input signal (ENABLE-B).
Step nr4
partial
result Test Result PASS: Diagnostic LED
“PWM Enable” L2 is LIGHT OFF.
Same as Step nr2.
Test Result FAIL: Diagnostic LED
“PWM Enable” L2 is LIGHT ON.
Same as Step nr2.
For all steps, the Test Result must be PASS.
Measure to adopt in case of Test Result FAIL:
Board ES927 is damaged

It is mandatory to replace the board with a new one.
