VFD-M Series part number. These fuses (or equivalent) must be used on all installations where

compliance with U.L. standards is a required.

CAUTION!

1. Make sure that power is only applied to the R/L1, S/L2, T/L3 terminals. Failure to comply may

result in damage to the equipment. The voltage and current should lie within the range as

indicated on the nameplate.

2. All the units must be grounded directly to a common ground terminal to prevent lightning strike

or electric shock.

3. Please make sure to fasten the screw of the main circuit terminals to prevent sparks which is

made by the loose screws due to vibration.

4. Check following items after finishing the wiring:

A. Are all connections correct?

B. No loose wires? C. No short-circuits between terminals or to ground?

4. Damaged insulation of wiring may cause personal injury or damage to circuits/equipment if it

comes in contact with high voltage.

5. The AC motor drive, motor and wiring may cause interference. To prevent the equipment

damage, please take care of the erroneous actions of the surrounding sensors and the

equipment.

6. When the AC drive output terminals U/T1, V/T2, and W/T3 are connected to the motor terminals

U/T1, V/T2, and W/T3, respectively. To permanently reverse the direction of motor rotation,

switch over any of the two motor leads.

7. With long motor cables, high capacitive switching current peaks can cause over-current, high

leakage current or lower current readout accuracy. To prevent this, the motor cable should be

less than 20m for 3.7kW models and below. And the cable should be less than 50m for 5.5kW

models and above. For longer motor cables use an AC output reactor.

8. The AC motor drive, electric welding machine and the greater horsepower motor should be

grounded separately.

9. Use ground leads that comply with local regulations and keep them as short as possible.

10. No brake resistor is built in the VFD-M series, it can install brake resistor for those occasions

that use higher load inertia or frequent start/stop. Refer to Appendix B for details.

11. Multiple VFD-M units can be installed in one location. All the units should be grounded directly

to a common ground terminal, as shown in the figure below. Ensure there are no ground

loops.

Note: Use twisted-shielded, twisted-pair or shielded-lead wires for the control signal wiring. It is

recommended to run all signal wiring in a separate steel conduit. The shield wire should only be

connected at the drive. Do not connect shield wire on both ends.

Analog inputs (AVI, ACI)

Analog input signals are easily affected by external noise. Use shielded wiring and keep it as



short as possible (<20m) with proper grounding. If the noise is inductive, connecting the shield

to terminal GND can bring improvement.

If the analog input signals are affected by noise from the AC motor drive, please connect a



capacitor (0.1μF and above) and ferrite core as indicated in the following diagrams:

Digital inputs (M0~M5)

When using contacts or switches to control the digital inputs, please use high quality



components to avoid contact bounce.

Digital outputs (MO1)

Make sure to connect the digital outputs to the right polarity, see wiring diagrams.



When connecting a relay to the digital outputs, connect a surge absorber or fly-back diode



across the coil and check the polarity.

Revision May 2008, ME14, SW V3.04 2-11

Chapter 2 Installation and Wiring|

General

Keep control wiring as far away as possible from the power wiring and in separate conduits to



avoid interference. If necessary let them cross only at 90º angle.

The AC motor drive control wiring should be properly installed and not touch any live power



wiring or terminals.

NOTE

If a filter is required for reducing EMI (Electro Magnetic Interference), install it as close as



possible to AC drive. EMI can also be reduced by lowering the Carrier Frequency.

DANGER!

Damaged insulation of wiring may cause personal injury or damage to circuits/equipment if it comes

in contact with high voltage.

 Pr.11. This parameter is used to determine the time required for the AC drive to decelerate

from the Maximum Output Frequency (Pr.03) down to 0 Hz. The rate is linear unless the S-

Curve (Pr.14) is “Enabled”.

 Pr.12 and Pr.13: Provide an additional Accel/Decel time although Time 1 is the default. A

Multi-Function input terminal must be programmed to select Accel/ or Decel/ Time 2 and the

terminal must be closed to select Accel/Decel Time 2 (See Pr.38 to Pr.42).

 In the below diagram, suppose the Maximum Output Frequency is 60 Hz (Master Freq),

Minimum Output Frequency (start-up) is 1.0 Hz, and accel/decel time 1 is 10 seconds. The

actual time for the AC drive to accelerate from start-up to 60 Hz is 9.83 seconds (deceleration

time is also 9.83 seconds), can be determined by the formula.

 When the JOG function is activated, the AC drive will accelerate from Minimum Output

Frequency (Pr.08) to Jog Frequency (Pr.16). Drive must be in “stop” status for the operator to

activate the JOG function. Likewise, during Jog operation, other commands cannot be

accepted through the keypad but FORWARD, REVERSE and STOP. The JOG function can

be remotely activated when the Jog terminal is closed, and if the Jog terminal opens, the AC

drive will decelerate from Jog Frequency to zero. The accel / decel time is entered as Jog

Accel / Decel Time (Pr.15). Multi-function Input terminals (M1-M5) can also be used to initiate

the JOG operation if so programmed.

The desired speed frequencies are entered in Pr.17 to Pr.23. When the associated multi-

function input terminal is closed, drive will run at one of these specific frequencies.

 Multi-step speeds (Pr.17 to Pr.23), Pr.78, Pr.79, and Pr.81 to Pr.87; are used for multi-step

motion control, which is executed in an orderly manner, similar to a PLC program.

 During deceleration, the DC bus voltage may exceed its maximum allowable value due to

motor regeneration. When this function is enabled, the AC drive will stop decelerating, and

maintain a constant output frequency to prevent from over-voltage tripping. Drive will resume

deceleration when the voltage drops below the setting for Pr.25.

Note: In applications where inertia is low, over-voltage during deceleration would not occur. When

inertia is high, the AC drive will automatically extend the deceleration period. If a faster stop is

needed, then a dynamic brake resistor should be used.

Chapter 4 Parameters|

 Under certain conditions, the AC drive output current may increase abruptly, and exceed the

value specified by Pr.26. This is commonly caused by rapid acceleration or excessive load on

the motor. When this function is enabled, the AC drive will stop accelerating and maintain a

constant output frequency. Drive will resume accelerating only after the current drops below

the setting for Pr.26.

Notes:

1. DC Braking during starting is used for loads that may move before the AC drive starts, such

as hoists and cranes. These loads may also be moving in the wrong direction. Under such

circumstances, the DC Braking can be used to hold the load in position before applying a

forward motion.

2. DC Braking during stopping is used to stop faster than the ramp-to-stop or to hold a

stopped load in position. A dynamic brake resistor may be needed in order to stop loads of

high inertia.

AC drive output is then turned off.

Pr.34

Base-Block Time for Speed Search

Unit: 0.1sec

Settings 0.3 to 5.0 sec Factory Setting: 0.5 sec

 When a momentary power loss is detected, the AC drive will stop its output and will wait during

a specified time interval called Base Block (entered in Pr.34) before resuming operation.

Setting of this parameter should make the residual output voltage due to regeneration almost

zero, before the drive resumes operation.

 This parameter also determines the search time when performing external Base-Block and

Fault Reset (Pr.72).

Pr.35

Maximum Current Level for Speed Search

Unit: 1%

Settings 30 to 200% Factory Setting: 150

 Following a power failure, the AC drive will start its speed search operation only if the output

current is greater than the value determined by Pr.35. When the output current is less than that

of Pr.35, the AC drive output frequency is at a “speed synchronization point” and will

accelerate or decelerate back to the operating frequency at which it was running prior to the

power failure.

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

100% on Pr.44 makes the Maximum Output Frequency (Pr.03) of the AC drive to correspond to the

+10VDC analog voltage output. (The actual voltage is about +10VDC, and can be adjusted by Pr.44)

The analog output voltage is also directly proportional to the output current of the AC drive. A setting

of 100% on Pr.44 makes the 2.5 times rated current of the AC drive to correspond to the +10 VDC

analog voltage output. (The actual voltage is about +10 VDC, and can be adjusted by Pr.44)

Note: Any type of voltmeter can be used. If the meter reads full scale at a voltage less than 10 volts,

then Pr.44 should be set by the following formula:

Pr.44 = ((meter full scale voltage)/10)×100%

For Example: When using a meter with a full scale of 5 volts, adjust Pr.44 to 50%

 Motor Rated Current

Unit: 0.1A

Settings 30.0% FLA to 120.0% FLA Factory Setting: FLA

 Factory setting is the AC drive rated current. When setting this parameter, just input the motor

rated current value without any calculation.

 Use the following criteria to determine the setting of this parameter: no-load current < rated

current of motor < rated current of AC drive. You can use this parameter to limit the output

current to the motor as to prevent overheat.

Pr.53

 Motor No-Load Current

Unit: 0.1A

Settings 00%FLA to 99%FLA Factory Setting: 0.4*FLA

 The rated current of the AC drive means 100%. Setting of this parameter affects the slip

compensation. The setting value must be smaller than the motor rated current setting in Pr.52.

(this parameter displays the value of actual current.)

Pr.54

 Torque Compensation

Settings 00 to 10 Factory Setting: 00

 This parameter forces the AC drive to increase its voltage output during start-up in order to

obtain a higher initial starting torque.

 Slip Compensation

Settings 0.00 to 10.00 Factory Setting: 0.00

Revision May 2008, ME14, SW V3.04 4-47

Chapter 4 Parameters|

 This parameter can be used to compensate motor slip. Although no linear, it typically adds 6Hz

for a setting of 10 if Pr.03=60 Hz. When the output current of the AC drive is greater than the

motor no-load current (Pr.53), the AC drive will adjust its output frequency according to this

parameter.

Pr.56

Over-Torque Detection Level

Unit: 1%

Settings 30 to 200% Factory Setting: 150

 A setting of 100% is proportional to the Rated Output Current of the drive.

 This parameter sets the Over-Torque Detection level in 1% increments. (The AC drive rated

current is equal to 100%.)

Pr.62

Over-Torque Detection Time

Unit: 0.1 sec

Settings 0.0 to 10.0sec Factory Setting: 0.1sec

 This is the duration for over-torque detection. When the output current is larger than the over-

torque detection level (Pr.61), an over-torque condition exists and the detection time (Pr.62) is

timed-out. Any of the multi-function output terminals set to indicate over-torque, will then close.

Unit: 0.01

Settings 0.01 to 160.0 Factory Setting: 1.00

 The coefficient K determines the multiplying factor for the user-defined unit.

 The display value is calculated as follows:

Display value = output frequency x K

 The display window is only capable of showing four digits, yet you could use Pr.65 to create

larger numbers. The display windows uses decimal points to signify numbers up to three digits

as illustrated in next page:

Display Number Represented

9999 The absence of a decimal point indicates a four-digit integer.

999.9

A signal decimal point between the middle and the right-most numbers is a true

decimal point. For example, the number 123.4 would be displayed as “123.4”.

A single decimal point after the right-most number is not a true decimal point; instead

9999.

it indicates that a zero follows the right-most number. For example, the number 12340

would be displayed as “1234.”

Two decimal points (one between the middle and the right-most numbers, and one

999.9.

after the right-most number) are not true decimal points; instead they indicate that two

zeros follow the right-most number. For example, the number 345600 would be

displayed as “345.6.”.

3.3 ADR (Communication Address)

Valid communication addresses are in the range of 0 to 254. An address equals to 0

means a broadcast to all AC drives (AMD) in the network. In this case, the AMD will not

reply to the master device.

For example, communication to AMD with address 16 decimal:

ASCII mode: (ADR 1, ADR 0)=’1’,’0’ => ‘1’=31H, ‘0’=30H

RTU mode: (ADR)=10H

3.4 Function (Function code) and DATA (data characters)

The format of data characters depends on the function code. The available function codes

are described as follows:

03H: read data from register
