2. Assign a parameter to the Analog Output port that we wish to calibrate.
This parameter should be one that we can change from minimum to
maximum for test purposes only. IDC Command Test is a good example.
See previous page on assigning an output.
3. Set IDC Command Test to 0.000 pu. This is the minimum. Adjust the
Zero adjustment screw on the isolator to read 4 mA.
4. Set IDC Command Test to 1.500 pu. This is the maximum. Adjust the
Span adjustment screw on the isolator to read 20 mA.
5. Repeat the process until no more adjustments are required.
6. Set IDC Command Test to 0.750 pu to ensure you read 12 mA (Half-
scale). Set IDC Command Test to 0.000 pu.
7. Assign the required parameter to the Analog Output port we have
calibrated.
8. Save all changes to NVRAM.
Configurable Alarms
Ensure that the configurable alarms have been programmed in the drive control.
Instructions on where to locate the following External Fault related tasks in the
manual are listed below:
• Setting Fault Masks: Refer to Fault Masks on page 128 (Chapter 3)
• Setting External Fault Text: Refer to User Definable External Text on
page 131 (Chapter 3)
• Setting Fault Classes: Refer to Drive Commissioning on page 169
The external faults can be tested by lifting the wires to all external warning / fault
inputs while running in system test mode. These wires are terminated at the
Digital I/O boards. Opening the circuit at any point will verify the external
fault’s configuration and functionality. However, it is preferable to actually force
the trips from the source. If that is not possible, then an acceptable alternative is
to lift the wire at the protective device.
18 Pulse Phasing Test Prior to applying medium voltage and running the drive, it is important to verify
the phase rotation on the input of all 18 Pulse drives. The following tests do not
need to be performed on AFE rectifier drives unless they incorporate
synchronous transfer:
• Line Terminal Resistance Measurements
• Application of Medium Voltage Power
ATTENTION: Do not short the lifted wire to ground when testing the circuit or
damage will occur to the Digital I/O board and possibly weld the equipment’s
trip contact.
