ATO FV12 Operating and maintenance manual
FV12 Torque transmitter use instructions
1. brief introduction：
The instrument uses the ARM kernel processor as the main
controller. Connecting to the dynamic torque sensor with the
signal output as the frequency, you can quickly read the current
torque value, the default torque frequency acquisition speed
is 100 times per second, with an OLED screen, showing the
current torque and speed value, and can also display the current
input frequency. Support torque to current or voltage with
speed. Supports the RS485 output. The RS485 can be directly
connected to our UPC to obtain the curve data, or it can also
be incorporated into the RS485 network using the MODBUS RTU.
Read the value of torque and rotational speed in real time.
Current and voltage output: 4-20MA, 4-12-20MA, 0-10V, 0-5-10V,

8. Basic operation instructions：
Modify parameters：Long press for a second to enter the menu, press again, you can switch back and forth in several
parameter interfaces. Press the key can switch the modification bit of the current parameter, and the long press can jump
around the parameters in the current display interface. Press key to modify the current bit of the current parameter. After
the modification is completed, you can directly jump back with the key to the main interface, and automatically save the
modified parameters.
Displays the interface switch：There are three display interfaces, the main display interface shows the current torque
speed, the second display interface shows the torque frequency, the third display interface shows the speed frequency, and
the three display interface can switch around after pressing the key in the main interface.
Modify numerical filtering：When customers need more stable torque values or react to faster torque values, they can
turn the digital filtering up or down. The larger the digital filtering, the more lagging and stable the torque value changes.
When the digital filter value is changed to 1, the torque value is the fastest reaction speed, at 100 times per second.
Curves can be collected in real time using MODBUS RTU or computer protocol.
Torque value zero：Press the long key at the main interface to establish the zero point.
factory data reset：This table power time is pressed on the key to restore the factory setting.
、Newsletter profile
The instrument data is 32 bits, with the high level before and the low level after, please read the multiple of 2. This instrument is equipped with
RS485 interface, which can use the company autonomous protocol and modbus RTU protocol. The communication mode set to 0 indicates the
company autonomous protocol, which is applicable to connect the company upper computer. Communication mode set to 1 indicates using the
modbus RTU protocol. Changing the port rate needs to take effect after a restart.
Communication adopts the instrument active upload protocol：The protocol has six bytes, D0~D5, D0D1 two bytes for torque, D2D3 two bytes
for rotational speed, and D4D5 for the CRC16 check bit of the first four bytes of data. The highest position of D2 indicates positive or negative
torque value, and 1 indicates negative torque value.0 Is a positive number. Depending on the Baud rate, the protocol uploads data at different
speeds, 9600 —— 50 times, 19200 —— 19200, and 200 times 38400 —— per second.
Communication uses the MODBUS-RTU protocol：Address domain + functional domain + data domain + check domain

、Transform output
This instrument is standard equipped with current and voltage transmission output, transmission output resolution of 1 / 16384, output mode of
4-20MA, 4-12-20MA, 0-10V, 0-5-10V, ±5V.
Parameter introduction
Transmission mode: Transmission mode set output mode is data directional output or absolute value output. The transmission mode 0 means the
transmission to the absolute value mode output, and the transmission mode 1 indicates that the transmission has a directional output, which is
generally used on the 0-5-10V transmission. The directional output is only effective when the transmission source is to torque.
Transmission zero point: The change of the transmission zero point will lead to the change of the zero-point output voltage and the output current,
which has been adjusted to the appropriate value before leaving the factory.
Supply capacity: Changing the "supply capacity" will result in the change of the maximum output voltage and the maximum current, with a
maximum supply capacity of 16383.
Range: the torque sensor range or the speed range, modify the range can change the change rate of the transmission output, corresponding to the
current used torque sensor range.
11、Calibration Settings
The first step is to input the current sensor range, with 20NM for example, a range set to 2000 and a display accuracy of 20.00.
Step 2 Long press the key to establish the current torque zero. Or enter the parameter to modify the torque zero frequency
The third step is the frequency of the sensor's full range output, i. e., the upper and lower limit frequencies, in Hz. This calibration operation is
complete.
