Introduction to Varia ble-Frequency Drives Getting Star ted 1–18 Intr oduction to V ariable-Frequency Drives The Purpose of Motor Speed Contr ol for Industry Hitachi in verters provide speed control fo r 3-phase A C induction motors. Y ou connect A C power to the in verter , and connect the in verter to the motor .
L200 2 Inverter Getting Star ted 1–19 T orque and Constant V olts/Her tz Operation In the past, A C variab le speed dri ves used an open loop (scalar) technique to control speed. The constant-volts-per -hertz operation maintains a constant ra tio between the applied voltage and the applied frequenc y .
Introduction to Varia ble-Frequency Drives Getting Star ted 1–20 In ver ter Output to the Motor The A C motor must be connected only to the in verter’ s output terminals. The output terminals are uniquely labeled (to dif ferentiate them from the input terminals) with the designations U/T1, V/T2, and W/T3.
L200 2 Inverter Getting Star ted 1–21 Intelligent Functions and P arameters Much of this manual is de voted to describ ing how to use in ve rter functions and how to conf ig- ure in verter parameters. The in verter is micro- processor- controlled, and has many indepen dent functions.

L200 2 Inverter Getting Star ted 1–23 Frequentl y Asked Questions Q. What is the main advantage in using an in verter to dri ve a motor , c ompared to alternativ e solutions? A. An in verter can vary the motor speed wi th very little loss of eff iciency , unlike mechanical or hydraulic speed control solutions.
Frequently Asked Qu estions Getting Star ted 1–24 Q. Why doesn’ t the motor hav e a neutral connection as a return to the in verter? A. The motor theoretically represent s a “balanced Y” load if all three sta tor windings ha ve the same impedance.
L200 2 Inverter Getting Star ted 1–25 Q. Ho w will I kno w if my application will require resistiv e braking? A. For ne w applications, it may be dif f icult to tell before you actually test a motor/driv e solution.

During those times, the in verter ke ypad keys will not function (e xcept for the Stop ke y).
L200 2 Inverter Configuring Drive P arameters 3–9 “F” Gr oup: Main Profile P arameters The basic frequency (speed) prof ile is defined by parameters contained in the “F” Group as show n to the right.
“A” Group: Standard Function s Configuring Drive P arameters 3–10 “A” Gr oup: Standard Functions Contr ol Source Settings The in verter provides fle xibility in ho w you control Run/Stop operation and set the output frequency (motor sp eed).
L200 2 Inverter Configuring Drive P arameters 3–11 Run Command Source Setting - F or parameter A002, the follo wing table provides a further description of each option, and a refe rence to other pag.
“A” Group: Standard Function s Configuring Drive P arameters 3–12 The in verter has other control sources that can temporarily ove rride the parameter A001 setting, forcing a dif ferent output frequenc y source. The follo wing table lists all frequency source setting methods and their relati ve priority (“1” is the highest priority).
L200 2 Inverter Configuring Drive P arameters 3–13 Basic P arameter Settings These settings af fect the most fundamental be ha vior of the in verter—the outputs to the motor . The frequency of the in verter’ s A C output determines the motor speed.
“A” Group: Standard Function s Configuring Drive P arameters 3–14 Analog Input Settings The in verter has the capability to accept an external analog input that can command the output frequency to the motor . V oltage i nput (0 –10V) and current input (4–20mA) are av ailable on separate terminal s ([O] and [OI], respecti vely).
L200 2 Inverter Configuring Drive P arameters 3–15 A016: External Frequency Filter Time Constant – This filter smooths the analog input signal for the in verter’ s output frequency reference. • A016 sets the f ilter range n=1 to 16. This is a simple moving a verage calculation, where n (number of samples) is va riable.
“A” Group: Standard Function s Configuring Drive P arameters 3–16 The example graph belo w shows a typical an alog input wa veform. The filter remo ves the noise spikes. When a speed change (such as le vel increase) occurs, the filter naturally has a delayed response.
L200 2 Inverter Configuring Drive P arameters 3–17 NO TE: When setting function A039 = 01, the actu al jogging deceleration time depends on the standard Deceleration T ime Setting F003/F203.
“A” Group: Standard Function s Configuring Drive P arameters 3–18 T orque Contr ol Algorithms The in verter generates the motor output according to the V/f algorithm selected. Parameter A044 selects the in verter algorithm for generating the frequency output, as sho wn in the diagram to the right (A244 for 2nd motor).
L200 2 Inverter Configuring Drive P arameters 3–19 Be aw are that running the motor at a lo w speed for a long time can cause motor ov erheating. This is particularly true when manual torque boost is ON, or if the motor relies on a built-in f an for cooling.

L200 2 Inverter Configuring Drive P arameters 3–21 DC Braking Settings The DC braking feature can provide additional stopping torque when compared to a normal deceleration to a stop. DC braking is particularly useful at low speeds when normal decelera- tion torque is minimal.
“A” Group: Standard Function s Configuring Drive P arameters 3–22 Frequency-related Functions Frequency Limits – Upper and lo wer limits can be imposed on the inv erter output frequency . These limit s will apply regard less of the source of the speed refer- ence.
L200 2 Inverter Configuring Drive P arameters 3–23 Jump Fr equencies – Some motors or machines exhi bit resonances at particular speed(s), which can be destructi ve for prolonged running at those speeds. The in verter has up to three jump fr equencies as sho wn in the graph.
“A” Group: Standard Function s Configuring Drive P arameters 3–24 PID Contr ol When enabled, the built-in PID loop calculates an ideal in verter output v alue to cause a loop feedback process v ariable (PV) to move closer in v alue to the setpoint (SP).
L200 2 Inverter Configuring Drive P arameters 3–25 A utomatic V oltage Regulation (A VR) Function The automatic voltage re gulation (A VR) featur e keeps the in verter output wav eform at a relati vely constant amplitude during po wer input fluctuations.

Glossary Appendix A A–2 Glossary Ambient T emperatur e The air temperature in the cham ber containing a po wered electronic unit. A unit’ s heat sinks rely on a lo wer ambient temperature in order to dissipate heat aw ay from sensiti ve electronics.
L200 2 Inverter Appendix A A–3 DC Braking The in verter DC braking feature stops the A C commutation to the motor , and sends a DC current through the motor windings in order to stop the motor . Also called “DC injection braking, ” it has li ttle ef fect at high speed, and is used as the motor is nearing a stop.
Glossary Appendix A A–4 Fr ee-run Stop A method of stopping a motor , caused when the in verter simply turns OFF its motor output connections. This may allo w the motor and load to coast to a stop, or a mechanical brake may intervene and shorten the deceleration time.
