with other boards to form various types of ac and dc
motor drives. The interface circuitry controls and processes drive and motor signals, and customer I/O. (The
interface circuitry and three main microprocessors are
used for other functions in TC2000 applications.) The
SDCC's three main microprocessors are:
NOTE Indicates an essential or important procedure,
practice, condition, or statement.
•
Drive Control Processor (DCP). An 80C186 microcontroller (U1) with numerous built-in peripheral
functions and uses both digital and analog I/O.

selects, wait-state generators, an interrupt controller, timer/counters, and the direct memory access
(DMA) controller. DCP software consists of user
interfaces, outer regulating loops (such as speed and
position), and system level functions.
•
Motor Control Processor (MCP). An 80C196 microcontroller (U21) with high-speed I/O, conventional digital I/O, analog I/O, timer/counters, and a
The SDCC interfaces with the other boards of the controller and external signals via eight connectors (designated
_PL). See Figure 3 for an SDCC layout diagram showing
the locations of the connectors and Tables 3 − 9 for the
pin signals of each connector. Connectors to other boards
are as follows:
•
1PL − I/O between the Power Supply/Interface Board
(DS200IMCP, DCI, SDCI, or DCFB) and the SDCC
•
2PL − ±5, 15, and 24 V dc inputs from the Power
Supply/Interface Board to the SDCC
•
3PL − SDCC outputs to the LAN Communications
Card (DS215SLCC)
•
6PL − I/O between the Drive Terminal Board
(531X305NTB) or Simple Drive Terminal Board
(DS200STBA) and the SDCC
•
7PL − I/O between the Signal Processor Card
(531X309SPC) or Multibridge Signal Processing
Card (DS200SPCB) and the SDCC (not present on
SDCCG3s)
•
8PL − I/O between the Drive Terminal Board
(531X305NTB) or Simple Drive Terminal Board
(DS200STBA) and the SDCC
•
9PL − Not Used (not present on SDCCG3s)

watchdog timer. MCP software consists of inner
loops such as current regulators, and motor/technology specific functions such as dc phase control, ac
motion control, and ac general purpose.
•
Co-motor Processor (CMP). A TMS320C25 digital
signal processor (U35) that performs math-intensive
functions for motor control algorithms too complex
for the MCP. The SDCC uses this processor and its
associated circuitry only when the drive requires the
additional processing capability. The CMP interfaces only to its EPROM and MCP/CMP dualported RAM.
The DS215SDCC card includes onboard software stored
in five memory chips: four EPROMs (U11, U12, U22,
and U23) that contain configuration data programmed at
the factory and one EEPROM (U9) that contains fieldadjustable parameters. These memory chips are contained in sockets on the SDCC.
When ordering replacement boards, note that the
DS200SDCC card does not include the five memory
chips mentioned above (the sockets are empty).
AUXILIARY BOARD MOUNTING PROVISIONS
NOTE
When replacing a DCC, specify a
DS215SDCC card as a replacement to ensure
that the five memory chips are in
cluded.
The SDCC has mounting provisions for other auxiliary
boards and modules. The following boards can be
mounted on the SDCC:
•
DS215SLCC or 531X306LCC LAN Communications
Card
CARD GROUPS
•
531X309SPC Signal Processor Card
There are currently three group numbers of the SDCC
available (G2 versions were never manufactured). The
variations between the groups are as follows:
•
DS200SPCB Multibridge Signal Processor Card
•
DS200SDCCG1A_ _: Used in AC2000, DC2000,
and EX2000 drive applications
LED DISPLAY
•
DS200SDCCG3A_ _: Variation of SDCC that has
reduced functionality (used in DC1000 drives)
•
DS200SDCCG4A_ _: Used in TC2000 turbine applications (same as G1A except with enlarged EE parameter storage area and different firmware)

A bank of 10 diagnostic LEDs is provided on the SDCC
and displays fault codes in either BCD (binary coded
decimal) or binary form, depending on the fault number
(see Figure 3 for location). The LEDs indicate faults in a
blinking mode as follows:
SDCC Drive Control Card
•
GEI-100029C
Faults 1 to 399
− slow blink rate
− BCD pattern (left-most two LEDs encode the
hundreds digit; next four, the tens digit; rightmost, the units digit; see Figure 1)

Faults 400 to 1023
− faster blink rate
− binary pattern (left-most LED is 29 [or 512], second-most LED is 28 [or 256], and so on; see Figure 2)
No fault or drive not running
− sequential blinking, two at a time
− blinking from outer positions inward to center,
and back
These same LEDs can be set by software jumper to also
coarsely display drive variables when running. (For example, displayed in an absolute or signed bar graph
mode). Setting software jumpers this way does not inhibit
the LED fault display.

The system trips when a hard reset is initiated; the system should not normally be reset
when running.
A reset can be generated in four ways:

RESET CIRCUITS
The SDCC provides four reset circuits, including a
RESET pushbutton.
•
By pressing the RESET pushbutton on the SDCC
(See Figure 3 for location.)
•
By applying +5 to +24 V dc to customer interface
points on the STBA or NTB/3TB boards (These
points interface with the SDCC through 6PL.)
•
By the SDCC generating a reset via programmed
software control
•
By the SDCC generating a reset via automatic internal hardware watchdog protection.
APPLICATION DATA
TESTPOINTS
The SDCC includes onboard testpoints for test and troubleshooting purposes. Testpoints are metal posts located
in specific signal paths. These signals can be measured or
viewed on an oscilloscope or other measuring instrument.
Table 1 lists and defines each testpoint. Figure 3 shows
testpoint locations.
CONFIGURABLE HARDWARE
The SDCC includes configurable hardware that must be
set correctly for the application:
•
Berg-type (manually movable) hardware jumpers,
identified by a JP nomenclature (see Table 2)
•
Wire jumpers, identified by a WJ nomenclature (see
Table 2)
These jumpers are used for factory test or user application
options. Most of the jumper selections have been factory
set. The test data sheets supplied with each controller (in
the drive/exciter door pocket) indicate these factory set
positions. Table 2 lists the jumper descriptions, showing
the default setting first.
Figure 3 is a layout diagram of the SDCC, showing the locations of all jumpers.

Board number and description
The DS215SDCC card includes onboard software stored
in five memory chips: four EPROMs (U11, U12, U22,
and U23) that contain configuration data programmed at
the factory, and one EEPROM (U9) that contains fieldadjustable parameters. These memory chips are contained
in sockets on the SDCC.
PROCEDURE FOR REPLACING BOARDS
WARNING
When ordering replacement boards, note that the
DS200SDCC card does not include the five memory chips
mentioned above (the sockets are empty).
To prevent electric shock, turn off power to
the drive, then test to verify that no power
exists in the board before touching it or any
connected circuits.
NOTE
The SDCC may also be used to replace a
531X301DCC Drive Control Card (DCC).
These instructions include information for
replacing a DCC with an SDCC, including
procedures for transferring software configuration parameters from the old DCC to the
new SDCC, and setting software parameters
(jumpers) on the SDCC for configuration
functions performed via hardware jumpers on
the DCC.
When replacing a DCC, specify a
DS215SDCC as a replacement to ensure that
the five memory chips are included.
CAUTION
To prevent equipment damage, do not remove
boards or connections, or re-insert them,
while power is applied to the drive.
Treat all boards as static-sensitive. Use a
grounding strap when changing boards or
software chips, and always store boards in
anti-static bags or boxes they were shipped in.
To replace an SDCC:
1.
Turn off the power to the drive, then wait several
minutes for all the capacitors to discharge. Test any
electrical circuits before touching them to ensure the
power is off.
2.
Open the drive's cabinet door to access the printed
wiring boards. (The DCC or SDCC is located in the
drive’s board rack, facing the front.)
WARRANTY TERMS
The GE Motors & Industrial Systems Terms and Conditions brochure details product warranty information, including the warranty period and parts and service
coverage.
The brochure is included with customer documentation. It
may be obtained separately from the nearest GE Sales Office or authorized GE Sales Representative.

SDCC Drive Control Card
If a programmer module is included, remove the programmer by pulling the snaps (holders, located in
each corner) outward to release the programmer
cover and keypad, then pulling the programmer loose
from the KPPL connector. (The keypad plugs into
connector KPPL on the LCC or SLCC.)
7.
NOTE
It may be necessary to remove auxiliary
boards mounted on the DCC or SDCC as described in step 5 before disconnecting cables
from the DCC or SDCC.
4.
Carefully disconnect all cables from the DCC or
SDCC (and any auxiliary board mounted on standoffs) as follows:
−
5.
8.
Verify cables are labeled with the correct connector name (as marked on the card) to simplify reconnection.
−
For ribbon cables, grasp each side of the cable
connector that mates with the board connector
and gently pull the cable connector loose.
−
For cables with pull tabs, carefully pull the tab.
CAUTION
Always use the nylon washers when inserting
screws into the card to avoid damage to the
card.
16
b.
Insert the screws with nylon washers into the
same point on the back of the new SDCC as they
were removed from on the old card.
c.
Place standoffs into position on the front side of
the new SDCC and tighten the screws with nylon
washers to secure the standoffs.
Set all configurable items on the replacement (new)
SDCC in the exact position as those on the card being
replaced.
NOTE
Because of upgrades, boards of different revision levels may not contain identical hardware. However, GE Drive Systems assures
compatibility of its replacement boards.
9.
Release the DCC or SDCC from the board rack by
pushing back on the plastic snaps (holders), then remove the DCC or SDCC.
Remove the screws with nylon washers that secure the standoff to the old card by removing the
screws with nylon washers from the back side of
the old card.
When replacing an SDCC, if a board revision
has added or eliminated a configurable component, or re-adjustment is needed, refer to
Table 2. If replacing a DCC with an SDCC,
refer to the corresponding paragraph under
Replacing/Inserting Software.
CAUTION
6.
a.
NOTE
Remove any auxiliary boards mounted to the DCC or
SDCC by removing the screws (with nylon washers)
that secure the board to the standoffs on the DCC or
SDCC, then remove the auxiliary board.
Avoid dropping mounting hardware into the
unit, which could cause damage.
Move all standoffs from the card being replaced to
the replacement (new) SDCC as follows:
Install the new SDCC into the board rack, ensuring
that all holders snap into position to secure the
SDCC.
10. Reconnect all cables to SDCC as labeled. Ensure that
cables are properly seated at both ends.
11. Install auxiliary boards on standoffs (if applicable)
with screws (with nylon washers) removed in step 5
and reconnect all cables as labeled. Ensure that cables
are properly seated at both ends.
12. If a Programmer module is included, carefully plug
the keypad into connector KPPL on the LCC or
SLCC and snap the cover into place.
SDCC Drive Control Card
NOTE
After replacing the SDCC in an application
with critical analog I/O functions, the gains
and offsets may require fine-tuning to compensate for variations in component tolerances between the old card and the new.
GEI-100029C
Replacing an SDCC
When replacing an SDCC, transfer the onboard software
to the new card as follows:
NOTE
To ensure compatibility of the onboard software with existing equipment, transfer the
four EPROMs from the old card to the new as
described in steps 1 and 2.
HARDWARE ADJUSTMENTS
Most of the jumper selections have been factory set. The
test data sheets supplied with each controller (in the drive
door pocket) indicate these positions. Table 2 lists and
defines the jumpers.
1.
In most applications, all WJ jumpers are factory set to the
correct position, and all JP jumpers except JP1 should be
in position 1-2 (JP1 should be in position 2-3). Use these
settings unless the instructions indicate otherwise. As described previously, ensure that the jumpers on the new
card are placed the same as on the old card, unless the instructions indicate otherwise. Refer to Table 2, which lists
the default setting first. Figure 3 shows jumper locations.
CAUTION
To prevent damage to memory chips, ensure
that chips are properly oriented when inserting them into sockets.
2.
Repeat step 1, one chip at a time, for each of the remaining EPROM chips.
3.
Remove the EEPROM (U9) chip from the old card
and insert it into the respective socket in the new
SDCC.
4.
If the failure symptoms that caused the card to be replaced still exist, perform the following:
NOTE
Some of the configuration functions on the
DCC using hardware jumpers are implemented on the SDCC via software jumpers
(parameters stored in EEPROM). If replacing
a DCC with an SDCC, refer to the following
section, Replacing/Inserting Software, for information on setting software jumpers on the
SDCC to match hardware jumper settings of
the old DCC. (Also see Table 10.)
REPLACING/INSERTING SOFTWARE
The SDCC uses a different EEPROM chip than that used
on the DCC, and some of the hardware jumpers on the
DCC are implemented as software jumpers on the SDCC.
Therefore, the procedures for replacing/inserting software
differ, depending upon whether a DCC or SDCC is being
replaced. The following paragraphs describe the procedures for replacing an SDCC, and for replacing a DCC
with an SDCC.
Remove one of the four EPROM chips (U11, U12,
U22, or U23) from the old card and insert it into the
respective socket on the new SDCC.
a.
Install new EPROMs and (blank) EEPROM
(shipped with the new card if a DS215SDCC).
b.
Program the new EEPROM per the customer
software adjustment values using the ST2000
(see GEH-5860), GE Control Systems Toolbox
(see GEH-6333), LynxOS Drive Configurator
(see GEH-6203), or ST1000 Drive Configuration
Tools (see GEH-6341).
Replacing a DCC with an SDCC
When replacing a DCC with an SDCC, the replacement
card must be a DS215SDCC to ensure that the five memory chips are included. The configuration data from the
old DCC must be loaded into the new SDCC's EEPROM
per the procedure in this paragraph.
17
GEH-100029C
SDCC Drive Control Card
The EEPROM (U9) used on an SDCC has twice the capacity of that used on a DCC. Therefore, the chip from the
DCC cannot be merely transferred to the new card. To
maintain the configuration from the DCC, use the ST2000
(see GEH-5860), GE Control System Toolbox (see GEH6333), or LynxOS Drive Configurator (see GEH-6203) to
load the configuration into the EEPROM supplied with
the SDCC.
If the ST2000, GE Control System Toolbox, or LynxOS
Drive Configurator is not available, read the configuration
from the DCC EEPROM into a file as described in the
following procedure. This procedure requires a personal
computer capable of serial communications with the drive
via the COMPL port, and capable of uploading and downloading files.
NOTE
Step 1 of the following procedure can be performed with the DCC EEPROM installed in
either the DCC or SDCC. If the DCC
EEPROM is installed in an SDCC, fault 396
(EEBADSIZ) will occur. To prevent this fault
from interfering with the software upload, set
EE.3 to 21.
18
1.
With the original EEPROM installed, upload its configuration to a file by issuing the following serial
command to the drive:
^x0-4095<Enter>
NOTE
If the new EEPROM is totally blank (no programming label attached), parameters EE.2
and EE.3 must be set to 21 using a Programmer before performing step 2.
2.
Install the new EEPROM in the SDCC and download
the configuration file to the drive.
Table 10 lists and defines DCC hardware jumpers that
have been implemented as software jumpers on the
SDCC. After the DCC configuration has been loaded into
the SDCC EEPROM, refer to Table 10 and change any
software jumper settings required to match the hardware
jumper settings of the DCC.
SDCC Drive Control Card
GEI-100029C
NOTE
The following table defines the hardware jumpers on the DCC Drive Control Card that have been implemented as software parameters on the SDCC Drive Control Card. When replacing a DCC with an SDCC, if a
DCC hardware jumper listed has been moved from the default position (listed first in the following table), the
corresponding software parameter for the SDCC must be changed to the required value using either the
ST2000 (see GEH-5860), GE Control System Toolbox (see GEH-6333), or LynxOS Drive Configurator (see
GEH-6203).

SDCCG1 allows encoders 0, 1, and 2 to be used simultaneously with no restrictions, unlike the DCC which had
latency constraints on software encoder #0. This jumper
is used for backward compatibility only.
WARNING -- prior to revision 2.22, SDCC firmware tied
hardware encoder 0 to software encoder 0 and hardware
encoder 1 to software encoder 1. Revision 2.22 permits
this mode only by setting EE.7.0; the default mode for
EE.7.0 now becomes backward compatible with the DCC.
Note that hardware encoder #1 is not supported on the
SDCCG3; therefore this jumper should not be set.
