L100 Inverter Getting Star t ed 1–7 Intr oduction to V ariable-Frequenc y Drives The Purpose of Motor Speed Contr ol for Industry Hitachi in verters provide spee d control for 3-phase A C induction motors. Y ou connect A C pow er to the in verter , and connec t the in verter to the motor .
Introduction to Var iable-Frequ ency Drives Get tin g St ar te d 1–8 An in verter , in general, is a device that con verts DC po wer to A C pow er . The popular consumer po wer in verter is designed for po wering an A C appliance from a car battery; put 12VDC in, and get 115V A C 50/60 Hz out, for example.
L100 Inverter Getting Star t ed 1–9 In verter Input and Three-Phase P ower Hea vy industrial machinery often needs the additional po wer a vailable from higher voltage/c urrent sources, and from three-phase po wer . The Hitachi L100 Series of in vert- ers includes tw o sub-groups: the 20 0V class and the 400V class in verters.
Introduction to Var iable-Frequ ency Drives Get tin g St ar te d 1– 10 Intelli gent Functions and P arameter s Much of this manu al is de voted to describing ho w to use in verter functions and ho w to conf ig- ure in verter parameters. The in verter is micropro- cessor -controlled, and has man y independent functions.
L100 Inverter Getting Star t ed 1– 11 V elocity Profi l es The L100 in verter is capable of sophisticated speed control. A graphical representation of that capability will help you understand and program the associa ted parameters. This manual makes use of the velocity prof i le graph used in industry (sho wn at right).
Frequently A sked Questions Get tin g St ar te d 1– 12 Frequentl y Asked Questions Q. What is the main advantage in using an in verter to driv e a m otor , compared to alternati ve solutions? A. An in v erter can vary the motor speed with very little loss of ef ficienc y , unlike mechanical or hydraulic speed control solutions.
L100 Inverter Getting Star t ed 1– 13 Q. Why does t he manual or othe r documentation use terminology such as “ 200V class ” inste ad of naming the actual voltage , such as “ 230 V A C? ” A. A specific in verter model is set at the factory to work across a v oltage range particular to the destination country for that m odel.
Frequently A sked Questions Get tin g St ar te d 1– 14 exhibit leakage curren ts that increase with aging. And, a grounded chassis generally emits less e lectrical noise than an ungrounded one. Q. What type of motor is compatible with the Hitachi in verters? A.

L100 Inverter Operat ions and Monitoring 4–3 W arning Messa g es f or Operating Pr ocedures W ARNING: Be sure to turn on the input po wer supply after clos ing the front case. While being ener gized, be sure not to open the front case. Otherwise, there is the danger of electric shock.
Connecting to PL Cs and Other De vices Operati ons and Monitoring 4–4 Connecting to PLCs and Other De vices Hitachi in verters (driv es) are useful in many types of applications. During inst allation, the in verter ke ypad (or other programmi ng device) will f acilitate the initial conf igura- tion.
L100 Inverter Operat ions and Monitoring 4–5 Specificati ons 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 . Connec to r labeling is sho wn below .
Using Intelligent Input T erminals Operati ons and Monitoring 4–6 Using Intelli gent 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 internal (isolated) +24V field supply (P24) to po wer the inputs.
L100 Inverter Operat ions and Monitoring 4–7 Multi-Speed Sel ect The inverter provides storage parameters for up to 16 different target frequencie s (speeds) that the motor output uses for steady-state run c ondition.
Using Intelligent Input T erminals Operati ons and Monitoring 4–8 While using the multi-speed capability, you can monitor the current frequency with monitor function D01 during each s e gment of a multi-speed operation. There are two ways to program the speeds into the r egisters A20 to A35: 1.
L100 Inverter Operat ions and Monitoring 4–9 Jogging Command When the terminal [JG] is turned on and the Run command is issued, the inverter outputs the programmed jog frequency to the motor. Use a s witch between term inals [JG] and [P24] to activate the JG frequenc y.
Using Intelligent Input T erminals Operati ons and Monitoring 4– 10 T wo- stage Accelerat ion and Deceleration When terminal [2CH] is turned on, the inverter changes the rate of acceleration and deceleration from the initial set tings (F02 and F03) to use the s econd set of a cceleration/ deceleration values.
L100 Inverter Operat ions and Monitoring 4– 11 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 [ FRS] is turned off, the output resumes sending po wer to the motor if the Run command is still acti ve.
Using Intelligent Input T erminals Operati ons and Monitoring 4– 12 External T rip When the terminal [E XT] is turned on, the inverter enters the trip state, i ndicates error code E12, and stops the output. This is a general pur pose interrupt type feature, and the meaning of the error depends on what you connect to the [EXT] terminal.
L100 Inverter Operat ions and Monitoring 4– 13 Unattended Start Protec tion If the Run command is already set when po wer is turned on, the in verter starts running immediately after powerup. The Unattended Start Protection (USP) function pr e v ents that automatic startup, s o that the in verter will not run without outside interve ntion.
Using Intelligent Input T erminals Operati ons and Monitoring 4– 14 Software Loc k When the terminal [SFT] is turned on, the data of all the parameters and functions except the output frequency is locked (prohibited fr om editing). When the data is l ocked, the keypad keys cannot e dit inverter parameters.
L100 Inverter Operat ions and Monitoring 4– 15 Analog Input Current/V oltage Select The [AT] terminal selects whether the inverter use s the voltage [O] or current [OI] input terminals for external f requency control.
Using Intelligent Input T erminals Operati ons and Monitoring 4– 16 Reset In verter The [RS] te rminal causes the inverter to execute the reset ope ration. If the inverter is in Trip Mode, the rese t cancels the Trip state. When the switch betwe en the set terminals [RS] and [P24] i s turned on and off, the inverter executes the reset operation.
L100 Inverter Operat ions and Monitoring 4– 17 PTC Thermisto r Thermal Pr otection Motors that are equipped with a thermi stor can be protected from overheating.
Using Intelligent Output Terminals Operati ons and Monitoring 4– 18 Using Intelli gent Output T erminals The intelligent output terminals are programmable in a similar way to the intelligent input terminals. The in v erter has se v eral output functions which you can assign indi vidu- ally to three physical logic outputs.
L100 Inverter Operat ions and Monitoring 4– 19 Frequency Arri va l S ignal Frequenc y Arri va l [F A1] and [F A2] signals indicate when the output frequency acceler- ates or decelerates to arriv e at a constant frequenc y . Refer to the figure belo w .
Using Intelligent Output Terminals Operati ons and Monitoring 4– 20 Overload Adv ance Notice Signal When the output current e xceeds a preset v a lue, the [OL] t erminal signal turns on. The parameter C41 sets the overload threshold. The ov erload detection circuit operates during po wered motor operation and during regenerati ve braking.
L100 Inverter Operat ions and Monitoring 4– 21 Output Devi ation f or PID Contr ol The PID loop error is def ined as the magnitude (absolute v alue) of the dif fer- ence between the Setpoint (target v alue) and the Process V ariable (actual value). When the error magnitude e xceeds the preset v alue for C44, the [OD] terminal signal turns on.
Using Intelligent Output Terminals Operati ons and Monitoring 4– 22 Alarm Signal The in vert er alarm si gnal is acti ve when a f a ult has occurred and it is in the T rip Mode (refer to the diagram at right). When the fault is cleared the alarm signal becomes inactiv e .
