There are numerous applications where soft starting and limited current peak are needed, thereby making
direct starting of squirrel-cage motors impossible. Traditionally in such cases other types of starting with
reduced stator voltage have been resorted to. The best-known are star-delta starters, autotransformer
starters, stator resistance starters or using part winding motors.
Any reduced starting voltage imposes a current limitation, thus reducing the starting torque, but there will
always be peaks during the change from one point or state to another which can damage the machine being
driven.
Note that in general, all reduced voltage starts reduce torque in squared proportion to the current in the
phases of the motor (not on the line) and the latter in turn is reduced in linear proportion to the voltage. From
this it can be deduced that any start with reduced voltage reduces the torque in squared proportion to the
voltage per motor phase. From this point of view soft starting produces just like any other reduced voltage
start, a reduction in starting torque, according to the adjusted parameters. The advantage is the ease with
which this ramp can be controlled to produce a soft start in accordance with the actual requirement of the
machine.
Advantages of the ASTAT-BP Solid State Soft Starters
1
Increase in productivity and reliability with the use of static
soft starters
Starting and stopping the motor without steps or transitions lengthens the
life of power-driven machine mechanical elements, greatly reducing
stress on transmission and coupling parts.
Consequently, overhauling times are reduced and machine and facility
lifespans are lengthened.
Improvement in acceleration / deceleration characteristics
Being able to start by using the voltage ramp or alternatively by limiting
current lets acceleration fit the load characteristics. Application of a pulse
start may also be selected in cases of high static friction load.
Stopping may be made by cutting-off power or by soft stop ramp.
Internal bypass
In order to reduce heat dissipation and power loss and for better wiring
simplicity, an internal bypass device is incorporated in the ASTAT-BP.
Bypass is closed after ramping up and opens upon stop or soft stop
commands.
Protected motor
The soft starter protects the motor from overloads as well as from
incorrect operating conditions such as loss of an input or output phase,
blocked rotor, thyristor short circuit, etc.
Digital technology
The control system is based on the use of a highly specialized
microcontroller by which signals are treated digitally, thereby avoiding
deratings and adjustments common to analogue circuits and obtaining
excellent precision and speed of execution.
The control board is made with the technology of surface mounting
devices (SMD), which increases equipment reliability.
High level of immunity
Design of the unit was closely tied to the conditions of supply lines, which
handle more disturbances every day. The control signals are
opto-electronically isolated and various levels of protection have been set
up in the circuits to immunize the equipment against external disturbance
and its effects.
Easy to run and adjust
This unit can be used for a wide range of applications.
Adjustments are very easy to make and diverse options maybe selected
for have equipment capabilities suited to application needs every time.
Easy maintenance due to full monitoring
The alphanumeric display and the LEDs on its front overlay makes the
equipment working conditions known at any time.
Pump control
The ASTAT-BP includes several soft stop curves which is more effective
than the standard soft stop, reducing fluid surges or hammering in a pipe
line system. This method reduces the motor speed, by controlling internal
parameters in the motor as well as the output voltage in a close-loop
system.
Advanced functions
The ASTAT-BP includes advanced functions, like linear acceleration ramp,
forward and reverse jog, programmable I/O or connection to a control
system via Modbus protocol included as standard and other optional
protocols.
These functions allow the incorporation of the soft starter to a distributed
control net, in automated plant processes, together with other soft
starters,programmable controllers, variable speed drives, etc.

When ASTAT-BP is connected in DELTA Conf. only Soft Start Curve 0 (Standard) is applied.
Soft Start Curves 1-3 - Pump Control - Induction motors produce peak torque of up to 3 times the
rated torque towards the end of starting process. In some pump applications, this peak may cause a pressure
surge in the pipes.
Soft Start Curves 1, 2, 3 – During acceleration before reaching peak torque, the Pump Control
Program automatically controls the voltage ramp-up, thus, reducing peak torque.
Choice of four pump control acceleration curves: 0!, 1!, 2!, 3!
Soft Start Curve 4 (Torque) – Torque Controlled acceleration - This provides a smooth timecontrolled torque ramp for the motor and the pump.
Note:
Always start with SoftStart Curve 0. If towards the end of ramp, peak torque is too high (pressure is too
high) proceed to Soft Start Curve 1, 2, 3 or 4 in that order.
Used for controlled deceleration of high friction loads.
Determines the motor’s voltage ramp down time.
Determines torque towards the end of a soft stop.
If the current still flows after speed is softly reduced to
zero, you should increase the End Torque setting.
Stop Settings
44..77..44..1
Soft Stop Parameters
The ASTAT-BP incorporates 5 stopping curves that enable you to select the suitable torque curve
Soft Stop Curve 0 – Standard Curve (Default) – voltage is linearly reduced from nominal to zero.
The most stable and suitable curve for preventing prolonged stopping and motor overheating.
Soft Stop Curves 1, 2, 3 Pump Control – In some pump applications, when pumping to higher
elevation a considerable part of the torque is constant and does not decrease with speed.
24
Displays in MINIMIZED MODE and MAXIMIZED MODE.
25
The range of the Ramp DOWN Time can be extended to 1-90 sec. by using the EXPANDED SETTING as described in section 4.7.6 page 36.
It may happen that during the deceleration process when voltage decreases the motor torque abruptly falls
below load torque (instead of smoothly decreasing speed to zero), thus closing the valve and causing water
hammer.
Soft Stop Curves 1, 2 and 3 eliminate the water hammer phenomenon. In pump applications the
load torque decreases in square relation to the speed, thus correcting control of voltage to reduce torque
adequately and to smooth deceleration to a stop.
Note:
It is recommended that Soft Stop Curve 0 be used for all standard applications (not pumps).
To reduce water hammer, select Soft Stop Curve 1, then 2, then 3 in that order.
Soft Stop Curve 4 - Torque Curve - Provides linear deceleration of the torque. In certain loads, linear
torque deceleration can result in close to linear speed deceleration, thus eliminating stall conditions.
Note:
Always use Soft Stop Curve 0. If the motor stalls quickly instead of slowly decreasing its speed, select
Soft Stop Curve 1, 2, 3 or 4 in that order until the problem is solved.

Mounting
The ASTAT-BP must be mounted vertically. Allow sufficient space for suitable airflow above and below the
ASTAT-BP. To improve heat dissipation, it is recommended that you mount the ASTAT-BP directly on the rear
metal plate.
Notes:
(8) Do not mount the ASTAT-BP near heat sources.
(9) Surrounding air temperature in the cabinet should not exceed 50°C
(10) Protect the ASTAT-BP from dust and corrosive atmospheres.
Temperature Range & Heat Dissipation
5
(11) The ASTAT-BP is rated to operate within a temperature range of -10°C (14°F) to + 60°C (122°F).
Relative non-condensed humidity inside the enclosure must not exceed 95%.
50°C and up to 60°C, derate the current by 2.5% for each °C that is above 50°C.

Heat dissipation from the ASTAT-BP is calculated as:
Ploss=3x1.3xI+FAN loss
where:
I represents motor starting current. Note that the motor current during the start process is higher than the
motor rated current.
FAN loss represents power loss caused by all internal fans (refer to section 3 page 11 for fan loss per model).
For example, during start of a 820A motor when Current Limit is set to 400%, heat dissipation can be
calculated as:
Ploss=3x1.3x4x820+50=12,792Watt≈12.8kW
While a 820A motor is running (bypass is closed) and the motor current is 820A, heat dissipation can be
calculated as:
Ploss=3x1.3x0+100+50=3,198Watt≈3.2kW
Important Note: If the motor is started frequently, the cabinet should be designed for greater heat dissipation.
You can reduce the enclosure heating by adding ventilation.

66..11 Standard Starting Procedure
Review all parameters with the Mode and Select keys. Set parameters as required.
If necessary, return to Default Parameters (refer to section 4.5.3 page 21).
Connect mains voltage to the line terminals of the ASTAT-BP.
Set LCD to show Motor Current.
Apply START command
(In these cases the actual current is always lower than the Current Limit setting)
Starting Voltage- set to 30%
Current Limit - set to 300-350%
Ramp UP Time- set to 10 sec.
Upon start, the voltage quickly increases to the Starting Voltage value (30% of Un) and then gradually
ramps-up to nominal.
The current will simultaneously increase to peak current value (lower than the Current Limit setting),
before smoothly decreasing to the operating current.
6.2.2 High Inertia Loads: Crushers, Centrifuges, Mixers, Etc.
(In these cases the actual current is at the CURRENT LIMIT setting during part of the starting time)
Starting Voltage– set 40%
Current Limit– set 400%
Ramp UP Time– set 3 sec
Upon START the voltage and current increase until the current reaches the Current Limit value. The
voltage remains at this value until the motor reaches close to nominal speed, where current starts to decrease
and voltage continues to ramp-up to nominal.

(“water hammer”) of the gauge (abruptly stops the pump and the motor).
• Select Soft Stop Curve 1!! and increase Ramp DOWN Time to 15 seconds. Stop the pump and watch
the pressure gauge and the rate of closing of the check valve as the pump stops. Abrupt stopping of the
pump and motor will cause a loud audible noise emitted from the check valve.
• In most cases, “water hammer” is reduced. If “water hammer” persists, increase the time to 25 seconds
(confirm with motor manufacturer) and try again.
• If “water hammer” persists, increase the Soft Stop Curve setting to 2!!or 3!!. Each increase in the
Soft Stop Curve will reduce the abrupt stop of the pump, thus preventing the “water hammer”
phenomenon.

End Torque During Soft-Stopping a Pump Motor
While decelerating, the check valve may close before Ramp DOWN Time has elapsed, thus allowing current to
flow through stator winding causing unnecessary heat. Select End Torque sensitivity to 1 and stop the
pump, then confirm that the current stopped flowing through the motor shortly after the check valve closed.
If current still flows more than 3-5 seconds after check valve closure, increase End Torque (up to a
maximum value of 10) to stop current flow earlier.

In cases where the current transformers are connected externally (ASTAT-BP

Each current transformer is connected with its 2 wires only and these wires are
not grounded externally.
If previous action does not solve the problem and you are sure that no real
phase loss exists, you can set Phase Loss protection to Disable.
This situation can occur in rare cases when there is no real fault but the ASTATBP recognizes unusual behaviour like when Total Harmonic Distortion in Voltage
(THDV) in the network is high.
If this is a true case of Phase Loss then after setting Phase Loss protection
to Disable the motor will single phase and most likely be tripped by the over
load protection mechanism.
Phase loss might not be detected in motor operating under a light load.

WARNING
ASTAT-BP must be grounded at all times.
When testing the ASTAT-BP control/communication it is possible to use the control
module only without the power section (QBx0210-QBx1100 models).
The control module MUST be properly grounded to avoid danger of electrical shock!!
88..44 D.Set: Generator Parameters Wiring
Based on experience, the power (kW) of a diesel generator should usually exceed at least 1.8 times the
power (kW) of the motor in order to enable consistent motor starts, consult the factory if necessary.
However this should be checked on a case by case basis.
• When starting from a diesel generator, its voltage regulator (especially older type regulators) may be
affected during the starting process, thus causing rapid voltage fluctuations (~350V to ~500V in 400V
systems). In these rare cases, the voltage regulator must be upgraded – consult your diesel generator
supplier.
• When operating from mains and alternatively from a diesel generator, set normal starting characteristics
for mains and suitable parameters for the diesel generator in the DUAL Settings Parameters
settings. When starting from mains, the primary settings (suitable for main starting) will be operative.
Upon starting from a diesel generator, close the contact between the Control Supply and aux. input
terminal C1 to operate in D.Set: Generator Parameters mode.

Note:
QB* – ASTAT BP Range
Transient Protection
8
Line transient voltages can cause a malfunction of the ASTAT-BP and damage to the thyristors. All ASTAT-BPs
incorporate Metal Oxide Varistors (MOV) to protect from normal line voltage spikes.
When the ASTAT-BP is installed Inside Delta, the individual phases of the ASTAT-BP are connected in series with
the individual motor windings (6 conductor connections as with the star-delta starter). The ASTAT-BP must only
conduct about 58 % (=1\÷3) of the rated motor current. This allows the use of a significantly smaller ASTAT-BP.
Note that although when connected Inside Delta the current is reduced by 1.73 (√3), you should choose an
ASTAT-BP as if current is reduced only by 1.5. (1/1.5=0.667=67%)
For example:
For a motor with a rated current of 870A motor, a 960A starter will be selected to operate In-Line.
For Inside Delta ASTAT-BP, we calculate (870 x 67% = 580A) and select a 590A starter.
8.7.2 Notes on Inside Delta Connection
Inside Delta requires 6-wires to the motor.
Wrong motor connection might cause serious damage to the motor windings.
When installing the ASTAT-BP Inside Delta it is highly recommended to use a contactor in series to the ASTATBP or upstream (after motor protection) in order to avoid a damage to the motor if the ASTAT-BP short circuits.
The sinusoidal shape of the current might be imperfect. As a result, higher harmonic content is incurred (THD),
which may be twice the THD value as in the standard In-Line connection.
Motor heat may increase (due to the higher THD).
Phase sequence to the input of the ASTAT-BP (1L1, 3L2 & 5L3 terminals) must be correct. Otherwise, Phase Sequence fault will trip the ASTAT-BP immediately.
Higher torque can not be obtained.
The following factory preset features and functions are not active when Inside Delta mode is configured:
Kickstart
Soft Start Curve selection (Soft Start Curve 0 !! only).
Slow Speed TRQ. (slow speed)
Phase Sequence in OFF mode
Note :
For a high starting torque process, it is recommended to use the ASTAT-BP in the In Line connection.
IMPORTANT! If speed reversing is required, L1, L2 and L3 on the input of the ASTAT-BP can not be switched!
This is because Phase Sequence Disabled can not be implemented when ASTAT-BP is connected Inside
Delta. Thus, in order to reverse motor rotation two motor windings need to be switched as shown in the
following diagram:
(Winding V1-V2 is switched with winding U1-U2):
Reverse speed with ASTAT-BP connection Inside Delta with bypass contactor
to the ASTAT-BP and Inside Delta contactor.
C1 is an Inside Delta contactor.
U1-U2, V1-V2, W1-W2 are motor windings.
o Normally, 4ms <= time response <= 40mS.
o For a long response, time response <= 200mS.
• It is not recommended to transmit to the ASTAT-BP at a rate higher than once per second because this can
slow down ASTAT-BP response times.
• After storing parameter settings, there is a 1 sec. time period during which transmission to the same ASTAT-
BP is forbidden.
• Broadcast commands: not supported.
Notes:
* It is recommended that you connect 120 OHM resistors to both ends of the serial link.
* You must turn OFF (and ON again) power to the controller after changing Baud_Rate, Parity_Check or
Serial_Link_No (Slave Address). These parameters can only be modified manually and not through the
Serial Link.
Ignoring this instruction may result in permanent damage to the Serial Link Hardware
and might result in death or serious injury.
The Modbus RTU frame has the same principal structure for both the "Query" transmission from the Master to
the Slave (ASTAT-BP) and the Response transmission from the Slave to the Master:
"sync": Silent Interval for at least 3.5 character times
38
byte 1: Serial Link No. (= Slave Address) (1..247)
byte 2: Function (1,2,3,4,5,6,8,15 &16 are supported)
byte 3: Data Bytes ($XX)
. . ($XX)
. . ($XX)
byte n-1: CRC_Low ($XX)
byte n: CRC_High ($XX)
"sync": Silent Interval for at least 3.5 characters
A.3. SYNC (Silent Interval)
In RTU mode, messages use a "Silent Interval" more than 3.5 characters to "synchronize". This silent interval
separates transmission frames.
The entire frame must be transmitted as a continuous stream. A silent interval of more than 3.5 characters
during frame transmission will cause the receiving device to ignore the incomplete frame. The next byte is
assumed to be the Serial Link No. of the next frame.
Ignoring the frame can also occur if a second message is transmitted less than 3.5 characters from the end of
the previous frame. This causes the receiving device to consider that frame to be a continuation of the first
frame, thus resulting in a CRC error.
A.4. Serial Link No. (Slave Address)
This contains the ASTAT-BP Slave Number (1..247) on the serial link. The ASTAT-BP default value is 248, which is
the communication OFF condition. Serial Link No. is used as the first byte in both the "Query" transmission
from Master to Slave and in Response transmission from Slave to Master.
Note: Address 0, which is normally used for broadcast transmissions is not supported by the ASTAT-BP.
A.5. Function
The Function code informs the ASTAT-BP what action is requested. In most cases, Function is used as the
second byte in both the "Query" transmission from Master to Slave and in Response transmission from Slave
to Master.
38
When a parity bit is used each character is 11 bits. Therefore the silent interval is 3.5 * 11 / baud rate.

DATA
Data field includes information transferred to and from the ASTAT-BP. The specific data format is changed with
Function. When Word data parameters are transmitted, High Byte is transmitted first, followed by the Low
Byte.
CRC
The CRC (Cyclic Redundancy Check) two bytes (16 bit) are used to check the bytes of the entire frame.
It is generated in the master device and transmitted as the last two bytes of the frame (Low byte is appended
first, followed by the High byte). The slave device regenerates the CRC bytes and compares it to the CRC bytes
received. If the CRC bytes are not identical, the frame is flushed and no response is transmitted to the master.
ASTAT-BP MEMORY ORGANIZATION
The ASTAT-BP memory is organized according to the common Modbus addresses as follows:
ASTAT-BP Use Memory Type Max Query/Response Parameters
Actual Data 3X References Registers, # 1...128, addressed 0..127.
1. Actual Data parameters can be read both at 3X references starting at parameter #1, or (same parameters)
at 4X references starting at parameter #257 (100 hex higher). The additional mapping in 4X references is
designed for the convenience of Modbus Plus users.
2. ASTAT-BP can be controlled using the standard discrete commands (Coils, 0x references) or by writing to
parameter setting #753 with function 16. The additional control option using 4X references is designed for the
convenience of Modbus Plus users. To control, write to register #753 (address 752) only! (one register write,
with function 16).
3. Function 3 should be used to read 4X references. Function 4, to read 3x references.
Actual data includes measured values such as voltage and current. It includes both logic and statistical
information. All parameters are word (two bytes) parameters. The protocol supports only reading of these
parameters.
Parameter # is "1 based". The actual parameter address is 1 lower than parameter #. For example the address
of parameter #1 is 0 (30000).
The parameters have double mapping, at the following 3x & 4x references:

The protocol supports both reading and modifying of (most of) these parameters.
All of these parameters must be set with care. Inappropriate settings of some parameters can result in damage
to both the motor and the ASTAT-BP.
The parameters have the following 4x references:

Notes:
1. Parameter # is "1 based". The address is 1 lower than parameter #. For example address of parameter
#1 is 0 (40000).
2. When the Preset Single Register Function (06) is used to adjust one parameter setting, the
communication program checks that the parameter value is within the allowed limits. If not, an
Exception Response (Exception code 03) is returned instead of Normal response. See Exception
Responses later in this document.
3. If Preset Multiple Register Function (16) is used to adjust one or multiple parameter settings, then even
if one or more parameter settings are out of range, Normal response will be returned.
ASTAT-BP program will check later the value of each parameter. If it is beyond the allowed limit, the
limit value will be stored instead of the transmitted parameter value.
4. It is strongly recommended to preset parameter settings only when the motor is stopped. The ASTAT-BP
enables, however to preset one parameter (using function 06 only) when the motor is running at full
voltage. When motor is Soft Started, Soft Stopped, runs with energy saving or at slow speed, the ASTATBP ignores "Preset Single Register" or "Force Multiple Register" instructions. A "busy" Exception response
is returned by ASTAT-BP whenever its logic condition does not enable presetting.
5. Always wait more than 0.5 sec after using Functions 06 or 16 to preset parameter(s) before
transmitting again to the same ASTAT-BP.
6. Communication parameters 81...87 can only be read through the serial link. They can only be set
(written) manually.
7. It is the user’s responsibility to read and check all changed parameter settings after presetting.
Example 2:
To Read Stop Parameter settings 41-43 addressed as 40-42 (Soft Stop Curve, Ramp Down Time and End
Torque) of ASTAT-BP # 96. The host computer sends the following frame:
byte 1: Serial Link No. ($60)
byte 2: Function ($03)

byte 2: Function ($06)
byte 3: Starting Address High ($00)
byte 4: Starting Address Low ($09) (9)
byte 5: Preset Data High ($01) (300)

480V, Overvoltage DLY = 2Sec) to Parameter settings # 10-13(Addressed as 9-12) of ASTAT-BP # 128, the host
computer sends the following frame:
byte 1: Serial Link No. ($80)
byte 2: Function ($10)

byte 5: No. of Registers High ($00)
byte 6: No. of Registers Low ($04)
byte 7: CRC_Low ($XX)
byte 8: CRC_High ($XX)
Note:
A Normal response will be returned even if the preset data value is beyond the allowed range for one or more
parameter settings. Later the ASTAT-BP program will check the value of each parameter. If it exceeds the
allowed limit, the limit value will be stored instead the transmitted parameter value. It is the user’s
responsibility to read and check all parameter settings after presetting.
A.9. Control Register Write (4X Reference)
The ASTAT-BP incorporates one Control register intended for controlling the ASTAT-BP.
Address: The Control register is register # 753 addressed as 752 (40752).
In order to control the ASTAT-BP uses the Control register:
* Use Function 16 only.
* Use Address_High (page) = 2
* Use Address_Low = 240 (0F0H).
* Write to one register only.
* Use data_high (ms-byte of data) = 5AH.
* Data_low Bits resolution of the control register (ls-byte of data):
bit function Comment
d0 Stop Write "1" (ON) to stop.
d1 Soft Stop Write "1" (ON) to Soft Stop
d2 Start Write "1" (ON) to start
d3 Energy Save Write "1" (ON) to turn On. Write "0" (OFF) to turn Off.
d4 Dual Adjust Write "1" (ON) to turn On. Write "0" (OFF) to turn Off.
d5 Slow Speed Write "1" for Slow Speed. Write "0" for Normal Start.
d6 Slow Spd Reverse Write "1: for Reverse Direction. Write "0" for Forward Direction
d7 Reset Write "1" (ON) to Reset.
1. The Read function of the control register is not possible. To read the ASTAT-BP status, read the Logic_Status
(Actual parameter # 1).
2. Bytes 2..8 of the control frame must be exactly as in the following example. Otherwise an error message is
returned.
3. Hardwired Stop and Soft Stop inputs override the communication. To enable motor starting through
communication, terminals 4 and 5 (Stop & Soft stop) must be connected to the control voltage.
Example 5 - Control Register Write:
To start ASTAT-BP # 11, the host computer sends the following Query frame:
byte 1: Serial Link No. ($0B)
byte 2: Function ($10) Bytes 2..8 must be as in this example!!!
byte 3: Starting Address High ($02)
byte 4: Starting Address Low ($F0)
byte 5: No. of Registers High ($00)
byte 6: No. of Registers Low ($01)
byte 7: Byte Count ($02)
byte 8: Data High ($5A)
byte 9: Data Low ($04) Bit 2 is set, to start.
byte 10: CRC_Low ($XX)
byte 11: CRC_High ($XX)
The ASTAT-BP Normal response:
byte 1: Serial Link No. ($0B)
byte 2: Function ($10)
byte 3: Starting Address High ($02)
byte 4: Starting Address Low ($F0)
byte 5: No. of Registers High ($00)
byte 6: No. of Registers Low ($01)
byte 7: CRC_Low ($XX)
byte 8: CRC_High ($XX)
A.10. Discrete Commands (Coils, 0x References)
The ASTAT-BP incorporates 16 "Coils", (bit parameters), of which only 5 are operative. The other 10 are reserved
and were incorporated to enable the user to use word (16 bits) type parameters. Coil # is 1"1 based". The
actual address is 1 lower than coil #. For example coil #1 is addressed as 0 (00000). The coils have the following
0x references:
Coil # Coil Address Use in ASTAT-BP Comment
1 0 Stop Write "1" (ON) to stop.
2 1 Soft Stop Write "1" (ON) to Soft Stop
3 2 Start Write "1" (ON) to start
4 3 Energy Save Write "1" (ON) to turn On. Write "0" (OFF) to turn Off.
5 4 Dual Adjust Write "1" (ON) to turn On. Write "0" (OFF) to turn Off.
6 5 Slow Speed Write "1" for Slow Speed. Write "0" for Normal Start.
7 6 Slow Spd Reverse Write "1: for Reverse Direction. Write "0" for Forward Direction
8 7 Reset Write "1" (ON) to Reset.
To read coils 1..8 status of ASTAT-BP # 10, the host computer sends the following Query frame:
byte 1: Serial Link No. ($0A)
byte 2: Function ($01)
byte 3: Starting Address High ($00)
byte 4: Starting Address Low ($00)
byte 5: No. of Coils High ($00)
byte 6: No. of Coils Low ($08)
byte 7: CRC_Low ($XX)
byte 8: CRC_High ($XX)
The ASTAT-BP response when coils 7..0 are OFF OFF OFF ON OFF ON OFF OFF:
byte 1: Serial Link No. ($0A)
byte 2: Function ($01)
byte 3: Byte Count ($01)
byte 4: Data (coils 7..0) ($14)
byte 5: CRC_Low ($XX)
byte 6: CRC_High ($XX)
Example 7 - Force Single Coil:
To stop the motor controlled by ASTAT-BP # 1, the host computer writes "1" to the
"STOP COIL" (coil 1 addressed as 0) .
Note: For the Force Single Coil Function, Force Data of $0000 forces "0" = OFF.
Force data of $FF00 forces "1" = ON. The "Query" frame is sent by the host:
byte 1: Serial Link No. ($01)
byte 2: Function ($05)
byte 3: Coil Address High ($00)
byte 4: Coils address Low ($00)
byte 5: Force Data High ($FF) (force ON)
byte 6: Force Data Low ($00)
byte 7: CRC_Low ($XX)
byte 8: CRC_High ($XX)
The Normal (if no exception) response:
byte 1: Serial Link No. ($01)
byte 2: Function ($05)
byte 3: Coil Address High ($00)
byte 4: Coils address Low ($01)
byte 5: Force Data High ($FF)
byte 6: Force Data Low ($00)
byte 7: CRC_Low ($XX)
byte 8: CRC_High ($XX)
Notes:
1. Format is identical for the 3 "discrete" commands: Stop, S.Stop, Start & Reset. For these commands,
writing "OFF" to coil is meaningless. For example, when the ASTAT-BP is in the Stop condition, Coil #1
(Addressed as 0) = 1 (ON). Forcing the Stop Coil #1 to OFF does nothing. However, forcing the Start Coil
(#3) to ON will turn ON the Start Coil, but will also turn Off the Stop Coil.
2. For Energy Save, Dual Adjust, Slow Speed & Slow Speed Reverse Coils, writing "ON" will turn the option
The motor that is controlled by ASTAT-BP # 32 is stopped, Energy Save, Dual Adjust, Slow Speed and Reverse
are set to OFF.
To start the motor using the Dual Adjust parameters and enable Energy Saving feature (after end of starting),
the host computer should write "1" to the Start , Energy Save and Dual Adjust Coils no. 3-5, addressed as 2-4.
The "Query" frame sent by the host:
byte 1: Serial Link No. ($20)
byte 2: Function ($0F)
byte 3: Coil Address High ($00)
byte 4: Coils address Low ($02)
byte 5: No. of Coils High ($00)
byte 6: No. of coils Low ($03)
byte 7: Byte Count ($01)
byte 8: Force Data ($07)
byte 9: CRC_Low ($XX)
byte 10: CRC_High ($XX)
The Normal (if no exception) response is the echo of the Query:
byte 1: Serial Link No. ($20)
byte 2: Function ($0F)
byte 3: Coil Address High ($00)
byte 4: Coils address Low ($02)
byte 5: No. of Coils High ($00)
byte 6: No. of coils Low ($03)
byte 7: CRC_Low ($XX)
byte 8: CRC_High ($XX)
A.11. Discrete Hardwired Inputs (1x References)
The ASTAT-BP incorporates 16 Discrete Inputs, (bit parameters), from which only 6 are operative. The other 10
are reserved and were incorporated to enable use of word (16 bits) type parameters. Input # is "1 based". The
actual address is 1 lower than input #. For example input #1 is addressed as 0 (10000). The inputs have the
following 1x references:
Input # Address ASTAT-BP use Comment
1 0 Stop Open Input (Input reads" 0") to Stop. (Terminal # 4)
Close Input (Input reads "1") to enable Start / Run.
2 1 Soft Stop Open Input (Input reads"0") to Soft Stop. (Terminal # 5)

6..7 5 Reserved
8 7 External Fault Open Input = no fault (Input reads" 0") (Terminal #19)
To read all discrete inputs of ASTAT-BP # 12, the host computer sends the following Query frame:
byte 1: Serial Link No. ($0C) (12)
byte 2: Function ($02)
byte 3: Starting Address High ($00)
byte 4: Starting Address Low ($00)
byte 5: No. of Points High ($00)
byte 6: No. of points Low $08)
byte 7: CRC_Low ($XX)
byte 8: CRC_High ($XX)
The ASTAT-BP response when only Stop and Soft Stop terminals (Inputs 1&2) are connected:
byte 1: Serial Link No. ($0C) (12)
byte 2: Function ($02)
byte 3: Byte Count ($01)
byte 4: Data (Inputs 7..0) ($03)
byte 5: CRC_Low ($XX)
byte 6: CRC_High ($XX)
A.12. Diagnostics
Modbus Function 08 as implemented in the ASTAT-BP supports only Subfunction $0000. It provides for the
"loopback" (Return Query Data) feature, and for checking the Communication Serial Link between the master
and the ASTAT-BP.
To request ASTAT-BP # 1 to return Query data, the master should send following Query frame:
byte 1: Serial Link No. ($01)
byte 2: Function ($08)
byte 3: Subfunction High ($00)
byte 4: Subfunction Low ($00)
byte 5: Data High ($37)
byte 6: Data Low ($A5)
byte 7: CRC_Low ($XX)
byte 8: CRC_High ($XX)
The Normal (if no exception) response is the echo of the Query:
byte 1: Serial Link No. ($01)
byte 2: Function ($08)
byte 3: Subfunction High ($00)
byte 4: Subfunction Low ($00)
byte 5: Force Data High ($37)
byte 6: Force Data Low ($A5)
byte 7: CRC_Low ($XX)
byte 8: CRC_High ($XX)
When the master sends a query frame to an ASTAT-BP, one of the following four responses from the ASTAT-BP
is possible:
1. When no communication error is detected in the query, and no mistake is found by the communication
program module in the ASTAT-BP, a Normal response is returned.
2. If the ASTAT-BP does not receive the query frame (for example because of a disconnected serial link cable)
then no response is returned by the ASTAT-BP. After proper time the master will cause a timeout condition.
3. If the ASTAT-BP receives the query, but faulty CRC bytes and / or Parity bits are detected, no response is
returned by the ASTAT-BP. After the proper time the master will cause a timeout condition.
4. If no communication error is detected in the query, but the ASTAT-BP communication program module finds
an error such as an illegal function, data address or data value, or if the ASTAT-BP is busy, then an Exception
response is returned. The Exception response includes the Exception Code to inform the master about the type
of the error.
Exception Code Response Frame:
The Exception response frame holds fix number of 5 bytes. The first one, the Slave Address field, is the Serial
link number (transmitted in query and identical to ASTAT-BP Serial Link No.). The second byte, the Function field,
returns the echo of the transmitted query function but with the Most Significant Bit set to 1 (adding $80 to the
transmitted function code). The third byte is the Exception Code informing about the type of error. The last two
bytes are the CRC bytes.
Exception Codes supported by the ASTAT-BP:
Exception Code Type Comment
01 Illegal Function Requested Function is not supported.
Functions 1..6, 8, 15 or 16 are supported.
02 Illegal Data Address Data address is not allowable.
03 Illegal Data Value Data Value is not in allowable range.
06 ASTAT-BP Busy ASTAT-BP is busy now. The master retransmits the
message later.
Example 10:
The master is trying to force coil # 17 of ASTAT-BP 32. The ASTAT-BP incorporates only 16 coils.
The Illegal Data Address Exception code will be returned:
Query:
byte 1: Serial Link No. ($20) (32)
byte 2: Function ($05)
byte 3: Coil Address High ($00)
byte 4: Coils address Low ($11) (17, Non existent Coil)
byte 5: Force Data High ($00) ($0000 = "0" = Low)
byte 6: Force Data Low ($00)
byte 7: CRC_Low ($XX)
byte 8: CRC_High ($XX)
Exception response:
byte 1: Serial Link No. ($20)
byte 2: Function ($85) (Original + $80)
byte 3: Exception Code ($02) (Illegal Data Address)
byte 4: CRC_Low ($XX)
byte 5: CRC_High ($XX)
There are cases where the ASTAT-BP returns the Normal response, but the requested action cannot be
performed or is modified by the ASTAT-BP. Few examples are:
Requested Action Performed Action
Write Parameter settings during start process Ignored.
Write multiple parameters (Function 16), some are out of range Limit to allowed range.
Start command (Function 05) while Stop Hardwired Input is open Command ignored
It is the user’s responsibility to verify that the requested action was performed, by reading the value of the
modified parameters or the status of the command Coils.

APPENDIX B - PROFIBUS
B.1. Operation Mode in PROFIBUS:
ASTAT-BP supports both DPV0 and DPV1.
• DPV0 (Cyclic) allows:
o Start and shutdown.
o Read parameters (write parameters are not allowed via DPV0).
• DPV1 allows:
o Everything that DPV0 allows
o Change the cyclic parameters that display via DPV0.
o Write to registers.
B.1.1. Structure of the ASTAT-BP Receiving Frame
The first byte must be 0x5A (90 decimal)
The second byte is as follows:
3 Energy Save
4 Dual Adjust Write
5 Slow Speed
6
Note:
Bit number 0 is the LSB.
Example:
To send Reset, you first need to send 0x5A followed by 0x80.
B.1.2. Structure of the ASTAT-BP Transmitting Frame
The return frame contains 20 pairs of bytes (40 bytes total), representing the contents of 20 registers.
Each pair of bytes represents one register; all of the registers are 16 bit numbers.
The first byte represents the high value of the number (the MSB).
B.1.2.1.
Selection of the DPV0 Registers through Data Request (DPV1)
By writing to Slot number 1 and Index 2, you can change the register that appears in DPV0.
Remember that for each register there are 16 bits (two bytes/one word). The first byte represents the high
value of the register number.
To demonstrate this, let’s say that we want to see the following registers in DPV0 (cyclic):
Logic Status
Motor Current
Line Voltage
Hardwired Inputs
Thermistor Resistance
Thermal Capacity
Frequency
Phase Sequence
DIP Switch
Elapsed Run Time
Step 1: Find the register numbers
In this document, we will use a simple PROFIBUS master tool to demonstrate how to change parameters.
This tool is very simple and it allows you to modify the parameters only by writing the hex numbers.
Go to the table in section B.4 and find the register number for each register. The tool used in our example
requires the hexadecimal value so we also need to convert the register number into its hex equivalent.
The following table shows the register numbers for the registers used in our example.
Step 2: Update the register numbers
Write the following to slot number 1 and index number 2 using Data Request (DPV1).
B.1.3. Read and Write from Random Registers via Data Request
Reading or writing by Data Request (DPV1) allows you to read or write up to 20 registers in a single request.
In order to read or write via Data Request (DPV1) you need to perform 2 operations:
• First update the first register number that we want to read or write.
• Second read or write the register.
Configure the first register number by writing to slot number 2 and index number 2.
The length of the register number must always contain two bytes (word). If we want to read from register
number 5 we need to read from register number 0x0005. The first byte is the high part of the number (the
MSB).
To read or write multiple registers, we need to define the number of the words that we want to read or write.
All the settings to establish PROFIBUS communication are located under the Communication menu. Follow the
steps below to define the PROFIBUS in the ASTAT-BP.
Press the SET PAGE button until the following message appears:
Press SELECT FWD one time and the following message will appear:
