Service Data

Record customer name, location, date and drive ID number

Record drive nameplate data

Record motor nameplate data and compare it to the dimensional drawings

Record encoder nameplate data, if applicable

Record harmonic filter nameplate data, if applicable

Record source of control power, auxiliary cooling information, environmental conditions, drive password

Record all Dip switch settings, jumper settings and revision levels on printed circuit boards, power supplies,

communication modules and protective relays

Control Power Off Tests

Verify mechanical interlocks

Perform a resistance check on all devices and snubber circuits

Verify that the 3-phase control power coming into the control section is within specification. Most drives will

not have this option

Verify that all additional sources of low voltage power are within specification and have grounded neutrals

Control Power On Tests

Power Supply Tests

Apply control power and verify that AC voltages are within specifications

Verify the AC/DC output is 56V DC at the input of the DC/DC converter and at the input to gate driver power

supplies. Adjust if necessary

Verify the 20V output of SGCT IGDPS boards

Verify that all of the DC outputs in the DC/DC converter are at rated value

Verify that healthy lights are on for all control boards and firing boards (Use wire harness with power supply

adapter to test SCR gate driver boards or use the test power harness [part no. 80018-695-51; one for 2kV

drives, two for 3 and 4 kV drives and three for 6 kV drives] with the appropriate standard IEC line cord to test

the rectifier SGCT devices using the SPS power supply boards)

Converter Tests

Confirm that SCR and SGCT gating pulse sequence are correct for all devices

Programming the Operator Interface

Verify preliminary parameter settings

Calibrate signal conditioners

Set analog outputs

Fault masks / External faults

Analog I/O

PLC In/Out

System Tests

Perform a system test with low voltage control/test power

Prove all protection functions as desired

Verify that all emergency stop devices are functioning correctly

Calibrate the analog I/O

Verify that the drive cooling fan(s) is/are operating properly

Measure input contactor drop out time (2-cycle advance warning needed if input contactor is not part of drive

line-up)
