Description

0

0 = No error
1 = 12 bit A/D reference error

1

0 = No error
1 = 1.23V reference error

2

0 = No error
1 = 12 bit DAC error

3

0 = No error
1 = Temperature error

4

0 = No error
1 = Hall Sensor error

5*

0 = No error
1 = Excessive modulator current*

6
7

0 = No error
1 = EEPROM checksum error

* Even though excessive modulator current is being reported, modulator current is not actually
measured in the Logix 3400IQ. The value that is actually being is measured and reported is that the
