9.2.3 After-test Installation of
Parallel Drive Modules
After completing tests of the parallel drive module in
standalone mode, perform the following steps to return it
to operation.
1.
Remove power from the system.
2.
Reinstall the module into the parallel drive
system.
3.
Reconnect DC and AC busbars to the module.
4.
Connect the 44-pin ribbon cable MDCIC to the
connectors at the top of the module.
5.
Apply power to the drive.
Alarm 70, Illegal FC
Config
appears.
6.
Enter the parallel drive module type code (shown
on the drive module label) and save it to
EEPROM.
7.
Power cycle the drive. The parallel drive module
is ready for use.
9.2.4 Programming the Parallel Drive
Module
1.
Connect the 44-pin cable from the MDCIC of the
service kit to the top plate of the parallel drive
module.
2.
Connect the current scaling card to master drive
slot MK101 (Inv1) on the service kit MDCIC. See
chapter 15.1.3 Recommended Current Scaling Cards
3.
Connect the 24 V option D card to the option D
slot of the service kit.
4.
Apply 24 V DC power supply to the option card.
The parallel drive module is ready to be
programmed.
9.2.5 Service Kit Troubleshooting
•
If
alarm 240, Illegal PS config error
appears, verify
that the correct current scaling card is placed in
the parallel drive module.
•
If
alarm 14, short circuit
appears, check that the
current scaling card is placed correctly.
•
If
alarm 243, Brake IGBT fault
appears, ensure that
fuse microswitch harnesses are properly
connected in the parallel drive module, even
though the fuses are not used.
•
Do not place the current scaling card in slots
MK108–MK110.
•
Ensure that both ends of the 44-pin MDCIC cable
are properly seated in the connectors.
9.3 Signal Test Board
9.3.1 Signal Test Board
The signal test board (p/n 176F8437) provides access to
various signals that can be helpful in troubleshooting the
unit.
The signal test board is plugged into power card connector
MK104. Points on the signal test board can be monitored
with or without the DC bus disabled. Sometimes, the unit
needs the DC bus enabled and operating a load to verify
some test signals.
is a description of the signals available on the
signal test board.
Chapter 9 Special Test Equipment
of this
guide explains when these tests are used and describes
the correct test results.
