VFD-V Series

Preface

Thank you for choosing DELTA’s high-performance VFD-V Series. VFD-V Series

are manufactured by adopting high-quality components, material and incorporating the

latest microprocessor technology available.

 Getting Started

This manual will be helpful in the installation, parameter setting, troubleshooting, and daily

maintenance of the AC motor drives. To guarantee safe operation of the equipment, read

the following safety guidelines before connecting power to the AC drives. Keep this

operating manual handy and distribute to all users for reference.

WARNING

Always read this manual thoroughly before using VFD-V series AC Motor Drives.

DANGER! AC input power must be disconnected before any maintenance. Do not

connect or disconnect wires and connectors while power is applied to the circuit. Maintenance must be performed by qualified technicians.

CAUTION! There are highly sensitive MOS components on the printed circuit boards.

These components are especially sensitive to static electricity. To avoid damage to these components, do not touch these components or the circuit boards with metal objects or your bare hands.

DANGER! A charge may still remain in the DC-link capacitor with hazardous voltages

even if the power has been turned off. To avoid personal injury, please ensure that power has turned off before operating AC drive and wait ten minutes for capacitors to discharge to safe voltage levels.

CAUTION! Ground the VFD-V using the ground terminal. The grounding method must

comply with the laws of the country where the AC drive is to be installed. Refer to Basic Wiring Diagram.

DANGER! The AC drive may be destroyed beyond repair if incorrect cables are

connected to the input/output terminals. Never connect the AC drive output terminals U/T1, V/T2, and W/T3 directly to the AC main circuit power supply.

CAUTION! The final enclosures of the AC drive must comply with EN50178. (Live parts

shall be arranged in enclosures or located behind barriers that meet at least the requirements of the Protective Type IP20. The top surface of the enclosures or barrier that is easily accessible shall meet at least the requirements of the Protective Type IP40). (VFD-V series corresponds with this regulation.)

CAUTION! Heat sink may heat up over 70oC (158oF), during the operation. Do not

touch the heat sink.

3.6 Wiring Notice

1. There are corresponding ring terminals which will be included with each unit (15-30HP),

and please use the proper crimping tool by KST INC. P/N: KST-HDC38A for securing

the conductor.

2. When wiring up, and that the wiring route specifications are settled, please conduct the

wiring following the electrician regulations.

3. The connection between the three-phase AC input power and the main circuit terminal

R/L1, S/L2, T/L3 has to set up a none-fusing switch in between. The best is to series

connect with an electro-magnetic contactor (MC) so as to cut off the power supply at the

same time when the inverter protection function acts. (The two ends of the

electro-magnetic contactor should have the R-C Varistor).

4. There is no phase-order differentiation in the input power R/L1, S/L2, T/L3 and users

could connect with either one of use.

5. The ground terminal E is grounded with the third-type grounding method (with the

grounding impedance under 100Ω).

6. The grounding wire of the inverter could not be grounded at the same time with

machinery with grand current loading, like that of the electric soldering machine and of

the motor with grand horsepower; they have to be grounded individually.

7. The shorter the ground wire, the better it is.

8. When several inverters are grounded at the same time, be sure not to make it into a

ground circuit. Please refer to the following diagram:

FWD RUN

9. If the output terminals U/T1, V/T2 and W/T3 of the inverter are connecting relatively to

the U, V, and W terminals of the motor, the FWD indicator located on the digital control

panel of the inverter will be lit, and that means the inverter is running forward, and the

rotation direction of the motor will be shown as the right hand side diagram above; if the

REV indicator is lit, it means that the inverter is running in reverse direction, and the

rotation direction will be of the opposite direction compared with the above diagram. If

users are not sure of whether the connection between output terminals U/T1, V/T2 and

W/T3 of the inverter is of one-to-one connection with U, V, and W terminals of the motor,

simply swap either two wires among the U, V, and W terminals of the motor for

correction if the inverter is running forward while the motor is running at reverse

10. Be sure of the power voltage and the greatest current possible supplied.

11. When the “Digital Hand-held Programming Panel” is displayed, please do not

disconnect or dissemble any wiring.

12. No braking resistor is installed within the VFD-V inverter (selective purchasing item),

therefore, be sure to purchase and install the braking resistor if to be used on occasions

when the loading inertia is great or that it is of frequent start/stop.

13. Be sure not to connect the AC power with the terminals U/T1, V/T2 and W/T3 on the

power-generating side of the inverter.

14. Please tightly fasten the screws of the main circuit terminals so as to prevent sparks

generated due to the vibration and loosening of the screws.

15. Wiring of the main circuit and of the control circuit should be separated so as to prevent

erroneous actions. If the interlock connection is needed, please make it an

intersection of 90°.

16. If terminals U/T1, V/T2 and W/T3 on the power-generating side of the inverter is in need

of the noise wave-filter, it is then necessary to use the induction-type L-Varistor, but be

sure not to add in the phase-carrying capacitor or the L-C- and R-C-type wave filters.

17. Please use the separating wire as much as possible during control wiring, and be sure

not to expose the peeled-off separation net in front of the terminal to the external.

18. Please use the separating wire or tube as much as possible during power wiring, and

ground these two ends of the separating layer or tube to the ground.

19. If the installation site of the inverter is sensitive to interferences, please have the RFI

wave filters installed, and the nearer the inverter to the installation site, the better. In

addition, the lower the carrier wave frequency of, the less the interferences.

20. If the electric-leakage circuit breaker is installed in the inverter, it could serve as the

protection for the electric-leakage error, and as the prevention on the erroneous actions

of the electric-leakage circuit breaker; please select the sensor current above 200mA

with the action time of more than 0.1 second to have these actions accessible.

Bit

settings

Bit 0 1 Parameters are read only 201

Bit 1 1 Disable Frequency and Torque Command changes. 212

Bit 2 1 Keypad disable 224

 This parameter offers several functions.

1) The user may reset all parameters to their original factory settings.

2) The user may disable the keypad function.

3) The user may lock the parameters and allow them to be read only.

4) The user may disable the drive from accepting frequency or torque command

changes.

Throughout this manual, there are parameters such as this one, which use a term called

Bit Setting. This is simply the ability to have one parameter conduct multiple functions.

 Example 1: Assume the function of Pr. 00-02 is set for “Disable Frequency and Torque

Command changes.” By referring to the above chart, we know Bit 1 is equal to “2”,

because the hex to decimal conversion is (2 ^ the bit = the decimal value). Therefore

21 = 2, and the decimal “2”, should be set in Pr. 00-02 to disable the frequency and

torque commands.

 Example 2: Assume Pr. 00-02 is set for “Disable Frequency and Torque Command

changes” + “Keypad Disabled”. If we follow what we have learned, “Disable

Frequency and Torque Command changes” must be set to decimal “2”; and “Keypad

Disable” must be set to decimal “4”. The summation of the two decimal numbers gives

us 6. By entering the number 6 in the parameter, both functions are enabled.

 A setting of 1 enables the “Parameters are Read Only” feature, but Pr. 00-00~00-23,

continue to be accessed.

 If users would like to reset the parameters to original factory-settings, simply set the Pr.

00-02 to “9” or “10”. If a password was entered, this must first be decoded to allow the

parameters to be reset.

 This parameter defines the display content the User Defined setting. The User Defined

setting may be displayed upon power up (Pr. 00-03) or by pressing the Mode key on the

keypad and scrolling until the “U” is illuminated.

00-05 User-Defined Coefficient Setting

Factory setting 0

Settings 4 digit 0-3: the number of the decimal places

3-0 digit 40~9999

 This parameter allows the user to define a special value relative to the output frequency.

4th digit: Setting of the decimal places; 0 means that there is no decimal place and 3

stands for three decimal places.

3~0 digit: The actual value the maximum output frequency should correspond to.

 Example: To display rpm’s for a 4-pole 60Hz motor with a base speed 1800rpm and no

slip, Pr 00-05 must be set as follows.

Set the 4th bit = 0, 3rd bit = 1, 2nd bit = 8, 1st bit = 0, 0 bit = 0.

The result of setting 01800 in Pr. 00-05 determines the value at 60Hz (Maximum Output

Frequency).

 After this parameter is set, all functions relative to the frequency (except for the V/F

Curve frequency parameters) will automatically be changed to an RPM sale. RPM,

instead of Hz, will now be the unit for the keypad, and thus, if it is displayed as 60.00

before the setup, it will now display 1800 after the setup. Other parameters such as the

multi-step speed and JOG will be automatically changed also.

 Pr. 00-07: This parameter allows the user to input their password and disable the

parameter lockout. An incorrect password may be entered 3 times and then a “Pcode”

will flash on the display, alerting the user the password is incorrect. The drive must be

powered off and then powered on again to clear the Pcode display.

 Pr. 00-08: This parameter allows the user to input their password to lock out the

parameters from further changes.

To enter a password, the same password must be input twice within two minutes. To

verify the password was entered correctly, display the content of Pr. 00-08. If the

content is “1”, the password is entered. If the content is “0”, no password is entered.

 To permanently disable the password. Enter the password in Pr. 00-07, then enter 0

into Pr. 00-08 twice within two minutes.

 To re-activate the password, either enter an incorrect password into Pr. 00-07 or power

down and then re apply power to the AC drive.

This parameter allows the user to define the PU05 function. It also allows the user to

determine if the drive retains the direction and speed command after power has been

removed.

 Pr. 00-09 = Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 = xxxxx  Bit0 = This setting determines if it is necessary to press the PROG/DATA key first, to

enable the frequency/torque commands via up/down keys on the PU05.

VFD-V Series

 Bit1 = This setting allows the frequency/torque commands of PU05 and RS485 to either

be retained or forgotten after power has been removed.

 Bit2 = This setting allows the frequency/torque commands of the UP/DOWN external

terminals to either be retained or forgotten after power has been removed.

 Bit3 = This setting allows the FWD/REV direction to either be retained or forgotten after

power has been removed.

 Bit4 = This parameter does not have to be memorized into EEPROM; its original value

will be recovered after the power is turned back on.

Example: If the frequency is to be controlled by the UP/DOWN keys (bit 0 = 0) and the

frequency is to be retained after power off (bit 1 = 1) and the direction is also to

be retained (bit3=1) then Pr. 00-09 must be set to 01010.

Settings 0 V/F Control

1 V/F Control + PG

2 Vector Control (open loop)

3 Vector Control + PG (closed loop)

4 Torque Control

5 Torque Control + PG

 This parameter determines the control mode for the AC motor drive

0: V/F control: Drive will follow the V/F curve described by Pr. 01-00 to 01-08.

1: V/F control + PG: Drive will follow the V/F curve described by Pr. 01-00 to 01-08, but will

have more speed accuracy.

2: Vector Control: Enables Open Loop Vector control. To acquire the best results, it is

recommended to use the auto-tuning feature of the drive Pr. 05-00. By using this

feature, 200% rated torque may be obtained at 0.5Hz. For more open loop vector

control, refer to group 5 parameters. While in Vector Control, Pr. 01-03 to 01-08 and Pr.

05-04 are not used.

3: Vector control + PG: Enables the Closed Loop Flux Vector Control. The Closed Loop

Flux Vector Control will offer the highest torque and speed accuracy control. 200%

torque at 0Hz and a 1:1000 turn down ratio. While in Vector Control, Pr. 01-03 to 01-08

and Pr. 05-04 are not used.

Page 38

VFD-V Series

4: Torque control: Enables Torque (current) Control. Torque control allows the user to run

the AC drive based on current instead of frequency.

5: Torque control + PG: Enables the Closed Loop Torque Control. This will increase the

torque accuracy throughout the speed range and disabled Pr. 05-04.

Note: PI values for PG (closed loop), vector control (open loop) and torque control are

determined by Pr. 05-21~05-25.

 This parameter may also be used in Vector control to determine if the drive will skip the

zero point. If the drive skips the zero point, it will stop at the frequency determined by

Pr.01-09 and then start again in the opposite direction at Pr.01-09. The Vector control

will generate its own V/F curve, therefore please select 0 or 1 for this parameter setting

when in Vector mode.

00-12 Constant Torque Operation Selection

Factory setting 0

Settings 0 oL (100%) Constant torque operation

1 oL (125%) Variable torque operation

 When “1” is selected, the oL fault level is 125% of rated drive current. All other over load

ratings will not change, example: 150% of rated drive current for 60 sec.

00-13 Optimal Acceleration/Deceleration Setting

Factory setting 0

Settings 0 Linear acceleration/deceleration (follow Pr. 01-12 to 01-21)

Auto acceleration (follow Pr. 07-09), Auto deceleration (follow Pr.

06-02)

Linear acceleration/deceleration, but conduct the stall prevention

throughout the auto acceleration/deceleration function.

 Optimal Acceleration/Deceleration settings could ease the drive’s vibration during loaded

starts and stops. Also if the detected torque is small, the processor will speed up the

acceleration time and reach the set frequency at the fastest and smoothest startup

possible. At deceleration, the processor will monitor regenerated voltage and

automatically stop the drive at the fastest and smoothest time possible. Pr. 07-09

(Maximum Current Level for Speed Search) is regarded as the target of the output

current upon acceleration.

00-14 Time Unit for Acceleration/Deceleration and S Curve Factory setting 0

Settings 0 Unit: 0.01 sec

1 Unit: 0.1 sec

 This parameter determines the time unit for the Acceleration/Deceleration setting. This

allows the user to choose either high resolution or long acceleration/deceleration times.

Refer to parameters (Pr. 01-12~01-19), the 1st to the 4th Acceleration/Deceleration Time,

(Pr. 01-20, 01-21) the JOG Acceleration/Deceleration Time and (Pr. 01-24~01-27) the S

Operation Frequency

 The PWM carrier frequency has a direct effect on the electromagnetic noise of the motor

and heat dissipation of the drive. Therefore, if the surrounding noise is greater than the

electromagnetic noises of the motor, it is suggested to lower the carrier frequency, to

decrease the temperature of the drive. Although a quiet operation may be achieved with

a higher carrier frequency, it is necessary to take into consideration the relative wiring

length between the motor and drive and the effect this high frequency may have on the

motor windings.

 During SOFT PWM, the electromagnetic noises are less annoying at the same carrier

frequency for standard operation.

5-9

Page 41

VFD-V Series

 If the carrier frequency’s lower bound (Pr. 00-16) > the carrier frequency’s upper bound

(Pr. 00-15), then the carrier frequency will be operated at the upper bound level.

00-18 Auto Voltage Regulation (AVR) Function

Factory setting 0

Settings 0 AVR function enabled

1 AVR function disabled

2 AVR function disabled during deceleration

 This parameter selects the AVR mode. AVR is used to regulate the output voltage to

the motor.

 The input voltage to the AC motor drive could range from AC180V-264V at, 50Hz/60Hz.

When this occurs, the output voltage to the motor will also vary from 180 to 264 unless

the AVR function is enabled. When enabled, the AVR function will limit the voltage to the

motor, based on Pr. 01-02.

00-19 Automatic Energy-Saving Operation

Settings Bit 0 0 Disable automatic energy-saving operation

1 Enable automatic energy-saving operation

Bit 1 0 Maximum output voltage equals to the input power voltage

Maximum output voltage could be greater than the input power

voltage (over-modulation available)

 When the Auto Energy-Saving function is enabled, the drive will operate with full voltage

during acceleration and deceleration. At constant speed the AC drive will calculate the

optimal output voltage value for the load. It is possible for the output voltage to be 25%

below Maximum Output Voltage during auto energy saving operation. This function

should not be used with variable loads or continuous rated output loads. During these

types of conditions, the operation will cycle on and off, giving poor energy saving results.

Coast to stop: the drive will stop the output instantly upon a STOP command and the

motor will coast to stop according to its inertia (time unknown).

(1) In applications where the motor must stop after the drive is stopped, please select

“Ramp to Stop”. This is often a safety consideration.

(2) If the inertial load is large, it is recommended to set the drive for “Coast to Stop” to

eliminate nuisance Over Voltage faults.

 When setting the V/F curve, please follow this hierarchy for frequency:

01-01≥01-03≥01-05≥01-07. There is no hierarchy for the voltage setting, but a high

voltage at low output frequencies may cause motor failure. At low frequencies, always

use the lowest voltage necessary for the application.

01-09 Startup Frequency

Factory setting 0.50

Settings 0.00~400.00Hz

 The Start-up Frequency is the initial frequency output upon a RUN command. If the

startup frequency setting is greater than the Maximum Output Frequency (Pr. 01-00), the

drive will default to Pr. 01-00 as the start point.

 When the Pr. 07-12 (Speed-Tracing Function) is enabled, Pr. 01-09 (Start-up frequency)

is disabled.

01-10 Upper Bound Frequency

Factory setting 100.0

Settings 0.0~110.0%

01-11 Lower Bound Frequency

Factory setting 0.0

Settings 0.0~100.0%

 These parameters set the upper and lower limits of the output frequency. If the

command frequency is lower than the Lower Bound frequency, the motor will be

operating at ZERO speed; if the command frequency is greater than the Upper Bound

frequency, the motor will then operate at the Upper Bound frequency.

 The Acceleration Time the time needed for the drive to ramp from 0.0Hz to Maximum

Output Frequency (Pr. 01-00). The Deceleration Time is the time needed for the drive

to ramp down from Maximum Output Frequency (Pr. 01-00) to 0.00Hz.

 The acceleration/deceleration times will be disabled if Pr. 00-13 (Auto

acceleration/deceleration Selection) is set for automatic operation.

Acceleration/Deceleration times 2 to 4 are enabled by using a multi-function terminal



(Pr.02-01 to 02-06) set to 8 or 9. Acceleration/Deceleration time 4 may also be

selected via Pr. 01-23.

Acceleration/Deceleration time 1 are the factory default for out-of-the-box operation.



The acceleration time has a direct effect on the rise of current upon a RUN command.



If the application load is large and the acceleration time is short (1 second) it is possible

the drive will fault with an “oc”. Similarly if the deceleration time is short (1 second) it is

possible the drive will fault with an “ov” due to motor regeneration.

 Three of

six methods include a “Line Start Lockout” feature. When Line

the

start lock out is enabled, the drive will not recognize a RUN command upon power up. The VFD-V must see the terminal state change from low to high. This is a safety feature for applications where applying power does not determine a RUN command.

The Line Start Lockout feature does not guarantee the motor will never start under this

condition. It is possible the motor may be set in motion by a malfunctioning switch.

02-16 Counter Values Achieve the Pre-Set Values

Factory setting 0

Settings 0~65500

 The input contact of the counter could set the multi-function terminal MI6 (with the

designated terminal Pr. 02-06 as 26) as the trigger terminal, and when the counting is over

(which reaches the destination), the signals could select one among the multi-function

output terminals (with Pr. 02-10~02-13 set as 21) to be the motion contact.

02-17 Designated Counter Value Achieved

Factory setting 0

Settings 0~65500

 When the counter value starts counting upward from 1 to the setting of this parameter, its

corresponding multi-function output terminal contact with the “arbitrary counting

achieves the output indication” function would start functioning. This parameter could

be utilized at the moment when the counting is almost to an end, and then, set the

output signal to enable the drive operating at a low speed till it stopped.

These interferences constantly affect the stability of analog control and using the Input

Noise Filter will create a more stable system.

 If Pr. 03-13 is large, the control will be stable, yet the response to the input will be slow. If

Pr. 03-13 is small, the control may be unstable, yet the response to the input will fast.

The analog output voltage is directly proportional to the output frequency of the AC drive. With

the factory setting of 100%, the Maximum Output Frequency (Pr.01-00) of the AC drive

corresponds to +10VDC analog voltage output. (The actual voltage is about +10VDC, and can

be adjusted by Pr.03-16).

The analog output voltage is directly proportional to the output current of the AC drive. With the

factory setting of 100%, the 2.5 times rated current of the AC drive corresponds to +10VDC

analog voltage output. (The actual voltage is about +10VDC, and can be adjusted by Pr.

03-16)

Note: Voltmeter specification: The sourcing capability of the output is limited to 0.21mA.

Sourcing voltage: 10V. Output resistance: 47kΩ.

If the meter reads full scale at a voltage less than 10 volts, then Pr.03-16 should be set

by the following formula:

Pr.03-16 = ((meter full scale voltage)/10) ×100%

For Example: When using the meter with full scale of 5 volts, adjust Pr.03-16 to 50%.

measures (R1, R2, Lc)

measures (R1, R2, Lc, Lm, calculated by the motor’s no-load

current)

 This parameter automatically measures the motor’s characteristics and enters the values

into Pr.05-02, Pr.05-06~09, Pr.05-12, Pr.05-16~19, respectively.

Note 1. The Torque/Vector control mode is not intended for use with multiple motors connected

to one AC drive.

Note 2. If two motors will be connected to one drive and both must be auto tuned, it is

necessary to set a multi-function input terminal to switch between Motors 1 and 2.

This will enable the drive to enter the calculated values into the correct parameter

positions.

Note 3. When using the Auto tune feature with a loaded motor, please set Pr05-00 = 2 or 3. A

setting of 2 or 3 is a “Static tune” and no movement of the motor is necessary to

calculate the motor characteristics. If a Static tune is desired, please make sure to

input the correct No-Load and Full-Load current before conducting the Auto Tuning

feature.

Motor Auto Tuning Procedure:

1. Make sure all the parameter settings are at the factory settings and all power wiring is

correct.

2. Remove any load on the motor before proceeding with the auto tuning (Nothing should be

connected to the motor shaft).

3. Enter the motor rated voltage in Pr. 01-02 and motor rated frequency in Pr. 01-01.

4. Set Pr. 05-00 = 1, 2, or 3, then press the “RUN” key on the keypad to execute the motor

auto-tuning operation (Caution: the motor will begin to turn if Pr.05-00 is set to 1). The

execution time is about 2 minutes. (The greater the horsepower of the motor, the longer the

acceleration/deceleration time should be set).

5. After the auto tuning procedure is complete, verify the parameters (Pr.05-02, Pr.05-06~09,

Pr.05-12 and Pr.05-16~19) have been updated. If not, set Pr.05-00 = 1 to 3 and press the

“RUN” key again.

based on the requirement of the application.

05-01 Full-Load Current of Motor 1 Factory setting A(100%)

Settings XXXA(30~120%)

 This parameter will limit the AC drive output current in order to prevent the motor from

overheating.

 The value entered must be in Amps, and should be found on the motor nameplate.

 This parameter and Pr. 05-01 must be programmed correctly if the drive is to operated in

the Vector or Torque control mode, the Electronic Thermal Overload Relay is used (Pr.

06-09), or if the Slip Compensation function is used (Pr. 05-04).

05-02 No-Load Current of Motor 1 Factory setting A(40%)

Settings XXXA(5~90%)

The motor’s no-load current must be less than Pr. 05-01. This parameter directly



effects the amount of the slip compensation generated and the no-load current during

Vector control mode. Please set this parameter carefully.

05-03 Torque Compensation of Motor 1 (for the V/F Mode Only)

Factory setting 0.0

Settings 0.0~25.0%

This parameter increases the amount of voltage the drive will output to the motor during



operation to increase motor torque. The V/F Torque Compensation is based on the

setting of the parameter.

 Be careful when setting this parameter. Always start at the lowest setting and increase the

value until sufficient torque is achieved. A large Torque Compensation may generate

more voltage than needed and the motor will overheat and possibly be damaged.

05-04 Slip Compensation of Motor 1 (for V/F mode only)

Settings

0.0-10.0%

Factory setting 0.0

 While driving an asynchronous motor, an increasing load will cause an increase in slip.

This parameter may be used to compensate the nominal slip within a range of 0.0-10.0%.

When the output current of the drive is greater than the motor’s no-load current (setting of

Pr. 05-02), the drive will adjust the output frequency to the motor to compensate for slip.

Note 1. If Pr.05-02 > the rated current of the motor, the slip compensation will not work

correctly.

Note 2. To obtain effective slip compensation, use the auto tune feature Pr.05-00.

*The factory setting is twice the value for the 460V model

07-01 DC Braking Current Level

Factory setting 0

Settings 0~100%

This parameter sets the DC braking current level in percentage, for use with DC injection



braking. The percentage is based on the rated current of the AC drive. When programming

this parameter, be sure to increase the percentage slowly from 0, until sufficient braking

torque is obtained. A current level too high may damage the motor.

 During a power loss, if the power loss time is less than the time defined by this parameter,

the AC drive will resume operation. If the Maximum Allowable Power Loss Time is

exceeded, the AC drive output is then turned off.

 If the power loss occurs while the AC drive is under heavy load, it is possible all available

ride through power will be dissipated in the motor and the AC drive will shut down quickly

(less than 1 second).

The Momentary Power Loss function is only enabled while the “Lu” is displayed on the

 This parameter selects the method for speed search. Settings 2 and 3 are used when

the motor direction is always guaranteed. If it is possible the motor direction may be either REV or FWD upon a speed search, then selection 4 or 5 should be used.

 The speed search function is most applicable to a large Punch Press machine, blower,

or other high inertia application. While these applications normally stop, using the “Coast to Stop” method, this may take 2~5 minutes or the application comes to a complete stop. However, with the speed search function enabled, users could instantly start the drive without waiting for the flywheel to come to a stop and the drive would quickly find the speed and bring the motor to speed.

By adding an encoder (PG) to the application, a faster and more speed search would



occur.

08-01 Proportional Gain (P)

Factory setting 80.0

Settings 0.0~500.0%

 This parameter determines the gain of the feedback loop. If the gain is large, the

the gain is small, the response will be weak and slow.

08-02 Integral Time (I)

Factory setting 1.00

Settings 0.00~100.00 Sec

0.00: no integral

 This parameter determines the speed of response for the PID feedback loop. If the

integral time is long, the response will be slow. If the integral time is short, the response

will be quick. Be careful not to set (I) too small, since a rapid response may cause

oscillation in the PID loop.

 If the integral time is set as 0.00, Pr. 08-02 will be disabled.

08-03 Differential Time (D)

Factory setting 0.00

 PI Control: controlled by the P action only, and thus, the deviation cannot be eliminated

entirely. To eliminate residual deviations, the P + I control will generally be utilized.

And when the PI control is utilized, it could eliminate the deviation incurred by the

targeted value changes and the constant external interferences. However, if the I

action is excessively powerful, it will delay the responding toward the swift variation.

The P action could be used solely on the loading system that possesses the integral

components.

5-60

Page 92

VFD-V Series

 PD Control: when deviation occurred, the system will immediately generate some

operation load that is greater than the load generated single handedly by the D action to

restrain the increment of the deviation. If the deviation is small, the effectiveness of the

P action will be decreasing as well. The control objects include occasions with integral

component loads, which are controlled by the P action only, and sometimes, if the

integral component is functioning, the whole system will be vibrating. On such

occasions, in order to make the P action’s vibration subsiding and the system stabilizing,

the PD control could be utilized. In other words, this control is good for use with

loadings with no braking functions over the processes.

 PID Control: Utilize the I action to eliminate the deviation and the D action to restrain the

vibration, thereafter, combine with the P action to construct the PID control. Use of the

PID method could obtain a control process with no deviations, high accuracies and a

stable system.

08-08 Detection Time of the Feedback Error

3.4 The LRC Check of the ASCII Mode

The LRC Check is the added sum from “Address” to “Data Contents”. For example, in

3.3.1, the LRC Check for the inquiry message will be: 01H + 03H + 21H + 02H + 00H +

02H = 29H, then take the complementary of 2, D7H.

3.5 The CRC Check of the RTU Mode

The CRC Check starts from “Address” and ends in “Data Contents”. Its calculation is as

follows:

Step 1: Load the 16-bit register (the CRC register) with FFFFH.

Step 2: Exclusive OR the first 8-bit byte message command with the 16-bit CRC

Step 3: Shift the CRC register one bit to the right and fill in 0 to the higher bit.

Step 4: Check the value that shifts to the right. If it is 0, save the new value from

Step 3 into the CRC register, otherwise, Exclusive OR A001H and the

CRC register, then save the result into the CRC register.

Step 5: Repeat Steps 3 and 4 and calculates the 8-bit.

Step 6: Repeat Steps 2~5 for the next 8-bit message command, till all the

message commands are processed. And finally, the obtained CRC

CRC Check must be placed interchangeably in the Check Sum of the

message command.

What follows is the calculation example of the CRC Check using the C language: unsigned char* data  // index of the message command unsigned char length  // length of the message command
