Page 9: Unit Number Select Switch
F130 acts as a Special I/O unit for Omron SYSMAC CJ1 series PLC. The data exchange between CPU unit and F130 are carried out by the high performance relay area of I/O and DM area. Relay and DM number used by F130 can be selected by the unit number selection switch located on the front panel. -

Page 11: 6-Wire Connection
SHIELD CAUTION The strain gauge type sensor excitation voltage of the F130 is 2.5V or 10V (selectable by setting). Set within the maximum excitation voltage of the strain gauge type sensor you use, and then make connection. Use exceeding the maximum excitation voltage may cause abnormal heating and damage. -
Page 12: Connections To Terminal Block
A1 to A9 and B6 to B9 are unnecessary in this specification, please do not connect input and output signal lines to them. Do not apply the voltage from the outside, or do not short-circuit with parts. It may cause malfunction of F130 and external equipment. -
Page 13: 3．Data Exchange With Cpu
Parameter settings for using F130 as a Loadcell Interface. A set of initial setting data for each F130 is allocated, based on its unit number, to a DM area for high performance I/O unit (inside CPU unit), and is written to this area when the unit is powered on, or a refresh cycle is started. -

When the hold request bit turns OFF, data update is stopped, and the average measurement value of that time is held. -
Page 19: 4．Calibration Method
4-1. What is Calibration? Calibration is performed for matching the F130 to a strain gauge type sensor. That is, F130 must be properly adjusted to indicate 10.00kN when an actual load of 10kN is placed on the strain gauge type sensor. -
Page 20: Actual Load Calibration And Equivalent Input Calibration Procedure
Write initial setting data to the DM area that corresponds to Input initial setting data MACH No. Register initial setting data to F130. To do this, either power on F130 Power on, the F130, or restart it by toggling restart flag in the following or restart sequence: OFF →... -
Page 21: Preparation For Calibration
Minimum data items required for performing proper calibration are: Excitation voltage, Minimum scale division, Sensor rated output value, and Sensor rated capacity value. Initial setting data are registered when F130 is powered on or it restarts. Excitation voltage selection (m) Select the bridge voltage supplied to the strain gauge type sensor. -

5.MEASUREMENT SETTINGS 5. MEASUREMENT SETTINGS 5-1. Analog Filter Selection (m+2) A low-pass filter is provided for filtering input signals from the strain gauge type sensor and cancelingnoise components. The cut-off frequency can be selected from 3Hz, 10Hz, 30Hz, 100Hz, 300Hz, 1kHz. With an increase in the cut-off frequency, the response becomes faster, but noise components may be indicated. -
Page 25: 6．Measurement・Hold Functions
6-1. Measurement Function Measurement value and data update counter The F130 performs A/D conversion at a rate of 3000 times/sec to calculate the measurement value. Each time the measurement value is updated, the data update counter is incremented by one. Since the measurement value and counter value are returned in pairs, how often you see the measurement data of the F130 can be known from the progression of the counter value. -
