7Interface Definition
Hinweis
In the BUS system with an EFKA interface motor other modules (e. g. I/O) must have an address less than $7F.
Note
A BUS termination resistor of 100 Ohm is provided in the control. Therefore, the control must be the last module to
be connected to the RS485 BUS. If several controls are connected, see chapter “Examples of Connections“.
7.1 Baud Rate Selection
Baud rate Jumper in plug B3
125,000 Baud All pins open
41,667 Baud Connect pin 16 to pin 15 (0V)
31,250 Baud Connect pin 17 to pin 15 (0V)
9,600 Baud Connect pins 16 and 17 to pin 15 (0V)
7.2 Protocol
§Data transfer according to ISO 1745.
§Only the commandsdata link establishment and RTS are valid.
§The control is selected withaddress $F0 (preset value). If several controls are connected further addresses up to $FF
are valid.
§Data transfer in ASCII (see also chapter ASCII Data Transfer).
§One word = 10 bit (1 start bit, 8 data bits, 1 stop bit, no parity bit).
7.3 Transmit Timeout before “NAK“
After detecting an error the “NAK“ acknowledgment will only be sent after a “timeout”. See the following table for the
length of the “timeout” depending on the baud rate.
125,000 Baud 2ms Timeout
41,667 Baud 3ms Timeout
31,250 Baud 4ms Timeout
9,600 Baud 10 ms Timeout
7.4 Byte to Byte Timeout
If, in a telegram, a “timeout” is exceeded from one word to the next, “NAK” will be sent. Simultaneously, bit 6 is set in the
communication register (parameter 00). See the following table for the length of the “timeout” depending on the baud rate.
125,000 Baud 6ms Timeout
41,667 Baud 8ms Timeout
31,250 Baud 10 ms Timeout
9,600 Baud 22 ms Timeout

EFKA AB286A5400

7.5 Communication Monitoring (System Values D, Group E)
A “timeout” for communication monitoring can be set by means of parameter E3. This “timeout” can be set at 10-
millisecond steps within a range of 0 and 255 (max. 2.5 seconds). If, in this parameter, a value not equal to zero is inputted,
there must always be an RTS to or a data link establishment with the slave within the allowed time. If the “timeout” is
exceeded, the drive stops in position 2 and sets bit 6 in the communication register (parameter 00). The “timeout” starts
with the next telegram after the data link establishment for parameter E3. Monitoring can be deactivated by inputting the
value zero in parameter E3 (preset value). Please note that the new value becomes effective only with the next telegram.
7.6 Control Characters
SOH $01 start of header
ADR $F0 address (can be set)
STX $02 start of text
ETX $03 end of text
ACK $06 acknowledge
NAK $15 not acknowledge
ENQ $05 enquiry
BCC Check sum EXOR logic operation from ADR to ETX
7.7 Special Characters
= $3D equals / value assignment
, $2C Separator in list call
. $2E Separator
7.8 Data Link Establishment
Higher level control = Master, AB286A = Slave
Master transmits -SOH ADR STX Text ETX BCC
Slave transmits -ADR ACK If telegram o.k.
-ADR NAK In case of error
Parameters in the control are modified by the data link establishment. The Text contains the modification information.
The general form of a modification is: Parameter = Value.
Parameter number and corresponding range of values are described in chapter Parameters.
7.9 RTS
Master transmits -SOH ADR STX Text ENQ
Slave transmits -SOH ADR STX Text ETX BCC
-ADR NAK In case of error
The Master receives information on the control status by means of RTS. This information is transmitted in the form of
status bytes. RTS only transmits the parameter number. More information on status bytes is described in chapter
Parameters.
7.10 Text
The Text contains all default options for the modification of settings in the AB286A control or polling of operational
statuses. These setings and operational statuses are described in detail in chapter Parameters.

EFKA AB286A540013
7.11 Stop Input
0 = Run / 1 = Stop
The start of the drive can be suppressed or the running motor can be stopped immediately by the “stop“ signal. The drive
can only be restarted after a reset (hardware or software). The stop signal must be on for at least 10ms.
7.12 Error Output
0 = Ready for operation / 1 = Error
The “error“ signal is issued whenever one of the following items applies:
§Hardware error
§Software error
§External 180° signal missing
§Commutation transmitter cord or frequency converter disturbed
§Line voltage too low
§Blocking, motor overstrained
Error description parameter 01 bit 2: If the external synchronization window is found after the command “go to
reference point“, this bit will be set. The error signal is issued and the drive stops.
The error signal can be reset (hardware or software).
8Parameters
The parameters are divided into the following groups:
Group 0: Status and Control Registers
Contain information on the actual control status.
Group 1-4: Control Values
The control values correspond to the system values after power on. They can be modified online
during the functional sequence.
Group 5-7: System Values
The system values serve as basic settings which are rarely modified. These values can be programmed
once and are saved after power off.
Attention: The system values cannot be modified during sewing.
Group E: Operational Statuses
The actual operational statuses can be read out here, e. g. actual counter reading or actual speed.
Group F: Characteristics

8.1 Special Features
When setting the speeds (parameters 10, 11, 61, 62, 63 and 64), half the value must be transmitted, i.e. the value “2000”
[2 RPM] must be transmitted for a requested speed of 4000 [RPM].
8.2 Bit Descriptions
8.2.1 “RDY“ Bit 5 in Status Byte 1
The “ready bit“ will not be set in case of the following errors:
0 = Error, as described below / 1 = Ready for operation
§Hardware error
§Software error
§Position transmitter not connected or defective
§Commutation transmitter cord or frequency converter disturbed
§Line voltage too low
§Blocking, motor overstrained

8.2.2 “NPE“ Bit 6 in Status Byte 1
This status bit will be set if the drive is within a window of +/- 8 increments around the reference point after the command
“go to reference point”. When leaving this range, the bit will be erased. The drive goes to the reference point in conjunction
with control byte 1 bit 7 and the positioning speed (parameter 12). In order to stop exactly at the reference point the
positioning speed should be as low as possible.
8.2.3 “P1E, P1A, P2E, P2A, P3E, P3A“ in Status Byte 2
Status bits “PxE“ with increasing edge and “PxA“ with falling edge will be set for the corresponding position. These bits
are preserved until the next change of status of the respective position. Furthermore, the bits can be used for triggering an
interrupt (synchronization with position...).
8.2.4 “PSYN“ Bit 7 in Status Byte 1
This status bit is set after the position transmitter has been synchronized. Then the value in parameter E0 as well as all other
status signals of the positions are valid.
8.2.5 “P2T“ Bit 0 in Control Byte 2
If this bit has been set, a single impulse (LOW – HIGH – LOW) is issued at the output of position 2. This command will
only be executed at standstill. The bit is reset after issuing this impulse or whenever the drive has not stopped.
8.2.6 “2N“ Bit 1 in Control Byte 2
If this bit is set, the speeds are doubled. The quadruple speed must now be transmitted. Internally, the speed is limited to
10000 RPM. The positioning speed will not be doubled.
Control Byte 2 bit 1 = 0 èdouble speed
Control Byte 2 bit 1 = 1 èquadruple speed
8.2.7 “ZSTP_“ Bit 2 in Control Byte 2
If this bit is set, accurate positioning is disabled. The drive stops out of the positioning speed (parameter 68).
8.2.8 “PNLIM“ Bit 5 in Control Byte 2
At this setting the speed is limited if the pedal speed is higher. The pedal speed has priority if it is lower than this limit.
8.3 Functional Descriptions
8.3.1 Stop Segment Angle for Positioning (System -values C, Group 7)
An angle with which the stop point can be moved backward depending upon the set stop position can be set by means of
parameter 72. The positions (1E, 1A, 2E, 2A, 3E, 3A) will not be changed.
The preset value for parameter 72 is 0. The maximum value is 50 increments (e. g. 50 * 1.4° = 71.1°) and can be changed
in single increments. Transmission is done at 2 bytes.

EFKA AB286A540019
8.3.2 Run-Out Angle for Positioning (System Values D, Group E)
An angle with which the stop point can be moved forward depending upon the set stop position can be set by means of
parameter E2. The positions (1E, 1A, 2E, 2A, 3E, 3A) will not be changed. The preset value for parameter E2 is 6. The
maximum value is 25 increments and can be changed in single increments (i. e. 25 * 1.4° = 35°). Transmission is done at 2
bytes.
8.3.3 Accurate Positioning
Accurate positioning is time-optimized and reproducible. Ensure that the value of ramp 3 (the preset value in parameter 1A
corresponds to the value in parameter 5A) is lower than the maximum braking ramp determined by the system (3 to 5
[1/min * ms] lower than the maximum value). In order to determine the maximum braking ramp, set the value of ramp 3 to
the maximum (255). The value for ramp 3 is the quotient of speed and braking time (in ms).
In the example, the ramp is the quotient of speed change / time.
