L100 Inverter Operations and Monitoring 4–3 W arning Messages for Operating Pr ocedures Before continuing, please read the follo wing W arning messages. W ARNING: Be sure to turn ON the input powe r supply only after closing the front case. While being ener gized, be sure not to open the front case.
Connecting to PLCs and Other Devices Operations and Monitoring 4–4 Connecting to PLCs and Other De vices Hitachi in verters (dri ves) are useful in man y types of applications . During installation, the in verter ke ypad (or other programming device) will f acilitate the initial configura- tion.
L100 Inverter Operations and Monitoring 4–5 Example Wiring Diagram The schematic diagram below pro vides a gene ral example of logic connector wiring, in addition to basic po wer and motor wiring co ve red in Chapter 2.
Example Wiring Di agram Operations and Monitoring 4–6 Specifications of Contr ol and Logic Connections The control logic connectors are located just behind the front panel half-door . The relay contacts are accessible behind the main door . Connector labeling is shown belo w .
L100 Inverter Operations and Monitoring 4–7 T erminal Listing Use the follo wing tables to locate pages for intelligent input and output material in this chapter .
Using Intelligent Input Terminals Operations and Monitoring 4–8 Using Intelligent Input T erminals T erminals [1], [2], [3], [4], and [5] are identical, programmable inputs for general use. The input circuits can use the in verter’ s inte rnal (isolated) +24V f ield supply (P24) to power the inputs.
L100 Inverter Operations and Monitoring 4–9 Forwar d Run/Stop and Re verse Run/Stop Commands: When you input the Run command via the terminal [FW], the in verter ex ecutes the Forw ard Run command (high) or Stop command (lo w).
Using Intelligent Input Terminals Operations and Monitoring 4–10 Multi-Speed Select The inverter can store up to 16 different target frequencies (speeds) that the motor output uses for steady-state run condition.
L100 Inverter Operations and Monitoring 4–11 While using the multi-speed capability, you ca n monitor the current frequency with monitor function D_01 during each se gment of a multi-speed operation. There are two ways to program the speeds into the registers A_20 to A_35: 1.
Using Intelligent Input Terminals Operations and Monitoring 4–12 Jogging Command The Jog input [JG] is used to command the motor to rotate slowly in small i ncrements for manual operation. The speed is limited to 10 Hz. The frequency for the jogging opera- tion is set by parameter A_38.
L100 Inverter Operations and Monitoring 4–13 T wo-stage Acceleration and Deceleration When terminal [2CH] is turned ON, the inverter changes the ra te of acceleration and deceleration from the initial settings (F_02 and F_03) to use the second set of accelera- tion/deceleration values.
Using Intelligent Input Terminals Operations and Monitoring 4–14 Free-run Stop When the terminal [FRS] is turned ON, the in verter stops the output and the motor enters the free-run state (coasting). If terminal [F RS] is turned OFF , the output resumes sending power to the motor if the Run command is still acti ve.
L100 Inverter Operations and Monitoring 4–15 External T rip When the terminal [EXT] is turned ON, the inverter enters the trip state, indicates error code E12, and stops the output. This is a gene ral purpose interrupt type feature, and the meaning of the error depends on what you c onnect to the [EXT] terminal.
Using Intelligent Input Terminals Operations and Monitoring 4–16 Unattended Start Protection If the Run command is already set when power is turned ON, the in verter starts running immediately after po werup.
L100 Inverter Operations and Monitoring 4–17 Software Loc k When the terminal [SFT] is turned ON, the data of all the parameters and functions (except the output frequency, depending on the setting of B_31) is locked (prohibited from editing). When the data is locked, the ke ypad keys cannot edit inverter parameters.
Using Intelligent Input Terminals Operations and Monitoring 4–18 Analog Input Current/V oltage Select The [AT] terminal selects whether the inverter uses the voltage [O] o r current [OI] input terminals for external frequency control.
L100 Inverter Operations and Monitoring 4–19 Reset In ver ter The [RS] terminal causes the inverter to execute the reset operation. If the inverter is in Trip Mode, the reset cancels the Trip state. When the signal [RS] is turned ON and OFF, the inverter executes the reset operation.
Using Intelligent Input Terminals Operations and Monitoring 4–20 Thermistor Thermal Pr otection Motors that are equipped with a thermisto r can be protected from overheating. Input terminal [5] has the unique ability to sense a thermistor resistance.
L100 Inverter Operations and Monitoring 4–21 Using Intelligent Output T erminals The intelligent output terminals are programma ble in a similar way to the intelligent input terminals. The in verter has se veral output functions that you can assign individu- ally to three physical logic outputs.
Using Intelligent Output Terminals Operations and Monitoring 4–22 Run Signal When the [R UN] signal is selected as an intelligent output terminal, the in verter outputs a signal on that terminal when it is in Run Mode. The output logic is acti ve lo w , and is the open collector type (switch to ground).
L100 Inverter Operations and Monitoring 4–23 Frequency Arriv al Signals The F requency Arrival group of outpu ts help coordinate external systems with the current velocity prof ile of the in verter . As the name implies, output [F A1] turns ON when the output fr equency arrives at the standard set frequency (parameter F_01).
Using Intelligent Output Terminals Operations and Monitoring 4–24 Frequency arri val output [F A1] uses the standard output frequency (parameter F_01) as the threshold for switching. In the figure to the right, Frequenc y Arriv al [F A1] turns ON when the output frequency gets within 0.
L100 Inverter Operations and Monitoring 4–25 Overload Adv ance Notice Signal When the output cur rent exce eds a preset value, the [OL] terminal signal turns ON. The parameter C_41 sets the ov erload threshold. The ov erload detection circuit operates during po wered motor opera- tion and during regenerati ve braking.
Using Intelligent Output Terminals Operations and Monitoring 4–26 Output Deviation f or PID Control The PID loop error is defined as the magnitude (absolute va lue) of the dif fer- ence between the Setpoint (target v alue) and the Process V a riab le (actual v alue).
L100 Inverter Operations and Monitoring 4–27 Alarm Signal The in verter alarm signal is acti v e when a f ault has occurred and it is in the T rip Mode (refer to the diagram at right).
Using Intelligent Output Terminals Operations and Monitoring 4–28 The alarm output terminals are connected as sh o wn belo w (left) by default. The contact logic can be in verted as sho wn (below right) by using the parameter setting C_33. The relay contacts normally open (N.
L100 Inverter Operations and Monitoring 4–29 Analog Input Operation The L100 in verters provide for analog input to command the in verter frequency output va lue. The analog input terminal group includes the [L], [OI], [O], and [H] terminals on the control connector , which provide for V oltage [O] or Current [OI] input.
Analog and Digita l Monitor Output Operations and Monitoring 4–30 Analog and Digital Monitor Output In the system design for in verter applications it is useful to monitor the in verter opera- tion from a remote location. In some cases, this requires only a panel-mounted analog meter (moving-coil type).
L100 Inverter Operations and Monitoring 4–31 TIP: When using the analog meter for monitori ng, adjust the meter so it has a zero reading when the [FM] output is zero. Then use scale factor B_81 to adjust the [FM] output so the maximum frequency in the in verter corresponds to a full-scale reading on the meter .
PID Loop Operation Operations and Monitoring 4–32 PID Loop Operation In standard operation, the in verter uses a reference source sel ected by parameter A_01 for the output frequency , which may be a fi x ed v alue (F_01), a v ariable set by the front panel potentiometer , or value from an analog input (v oltage or current).
L100 Inverter Operations and Monitoring 4–33 Configuring the In ver ter f or Multiple Motor s Simultaneous Connections For some applications, you may need to connect two or more motors (wired in parallel) to a single in verter’ s output.
