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-S 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 (Chapter 3).
!
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-S series corresponds with this regulation.)
!
CAUTION! The rated voltage of power system that is installed on AC drive must be
equal to or less than 240 Volts (460V model is 480 Volts) and the current must be equal
to or less than 5000A RMS.
!
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

3. During installation, follow all local electrical, construction, and safety codes for the country
the drive is to be installed in.
4. Ensure that the appropriate protective devices (circuit breaker or fuses) are connected
between the power supply and AC drive.
5. Make sure that the leads are connected correctly and the AC drive is properly grounded.
(Ground resistance should not exceed 100 Ω .
For 460V-class AC drive, the ground
resistance should not exceed 10Ω.)
6. Use ground leads that comply with AWG/MCM standards and keep them as short as
possible.
7. Multiple VFD-S units can be installed in one location. All the units should be grounded
directly to a common ground terminal. The VFD-S ground terminals may also be
connected in parallel, as shown in the figure below.
Ensure there are no ground loops.
Forward
running
8. 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, the motor will rotate counterclockwise (as
viewed from the shaft ends of the motor) when a forward operation command is received.
To reverse the direction of motor rotation, switch over any of the two motor leads.
9. Make sure that the power source is capable of supplying the correct voltage and required
current to the AC drive.
10. Do not attach or remove wiring when power is applied to the AC drive.
11. Do not monitor the signals on the circuit board while the AC drive is in operation.
12. For the single-phase applications, the AC input line can be connected to any two of the
three input terminals R/L1, S/L2, T/L3.
Note: This drive is not intended for the use with single-phase motors.
13. Route the power and control wires separately, or at 90°angle to each other.

14. 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.
15. If the AC drive is installed in the place where a load reactor is needed, install the filter close
to U/T1, V/T2, W/T3 side of AC drive. Do not use a Capacitor or L-C Filter
(Inductance-Capacitance) or R-C Filter (Resistance-Capacitance).
16. When using a GFCI (Ground Fault Circuit Interrupt), select current sensor with not less
than 200mA, and not less than 0.1-second detection to avoid nuisance tripping
3.6 Motor Operation Precautions
1. When using the AC drive to operate a standard 3-phase induction motor, notice that the
energy loss is greater than an inverter duty motor.
2. While using the standard induction motor at low speed, the temperature of the motor may
rise, so do not operate the motor at low speed for a long period of time.
3. When the standard motor operates at low speed, the motor output torque will decrease,
please decrease the load during the operation.
4. If 100% output torque is desired at low speed operation, it may be necessary to use a
special motor that can handle this load (inverter duty).

be programmed to select acceleration/deceleration time 2 and the terminals must be
closed to select acceleration/deceleration time 2. See Pr.4-04 to Pr.4-08.
In the diagram shown below, the acceleration/deceleration time of the AC drive is the
time between 0 Hz to Maximum Output Frequency (Pr.1-00). Suppose the Maximum
Output Frequency is 60 Hz, start-up frequency (Pr.1-05) is 1.0 Hz, and
acceleration/deceleration time is 10 seconds. The actual time for the AC drive to

Analog Current Meter
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.1-00) of the AC drive
corresponds to +10VDC analog voltage output. (The actual voltage is about +10VDC, and can
be adjusted by Pr.3-01).
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. 3-01)
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.3-01 should be set by
the following formula:
Pr.3-01 = ((meter full scale voltage)/10) ×100%
For example: When using the meter with full scale of 5 volts, adjust Pr.3-01 to 50%.

Example 5:
In this example a 1 volt negative bias is used. In a noise environment, it is advantageous to
use negative bias to provide a noise margin (1V in this example).
Example 6:
In this example, a negative bias is used to provide a noise margin. Also a potentiometer
frequency gain is used to allow the Maximum Output Frequency to be reached.
Example 7:
In this example, the potentiometer is programmed to run a motor is both forward and reverse
direction. A motor will be idle when the potentiometer position is at mid-point of its scale.

There is a built-in RS-485 serial interface, marked (RJ-11 Jack) on the control
terminal block, for VFD-S Series. The pins are defined above.
Each VFD-S AC drive has a pre-assigned communication address specified by Pr.
(9-00). The computer then controls each AC drive according to its communication
address.
VFD-S can be setup to communicate on Modbus networks using one of the
following modes: ASCII (American Standard Code for Information Interchange) or
RTU (Remote Terminal Unit). Users can select the desired mode along with the
serial port communication protocol in Pr. 9-04.

ADR (Communication Address)
Valid communication addresses are in the range of 0 to 254. Communication address
equals to 0 means broadcast to all AC drives (AMD), in this case, the AMD will not reply
any message 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

CRC (Cyclical Redundancy Check) is calculated by the following steps:
Step 1 : Load a 16-bit register (called CRC register) with FFFFH.
Step 2: Exclusive OR the first 8-bit byte of the command message with the low order byte
of the 16-bit CRC register, putting the result in the CRC register.
Step 3: Examine the LSB of CRC register.
Step 4: If the LSB of CRC register is 0, shift the CRC register one bit to the right with MSB
zero filling, then repeat step 3. If the LSB of CRC register is 1, shift the CRC
register one bit to the right with MSB zero filling, Exclusive OR the CRC register
with the polynomial value A001H, then repeat step 3.
Step 5: Repeat step 3 and 4 until eight shifts have been performed. When this is done, a
complete 8-bit byte will have been processed.
Step 6: Repeat step 2 to 5 for the next 8-bit byte of the command message. Continue
doing this until all bytes have been processed. The final contents of the CRC
register are the CRC value.
When transmitting the CRC value in the
message, the upper and lower bytes of the CRC value must be swapped, i.e.
the lower order byte will be transmitted first.
The following is an example of CRC generation using C language. The function takes two
arguments:
Unsigned char* data
Unsigned char length
a pointer to the message buffer
the quantity of bytes in the message buffer
The function returns the CRC value as a type of unsigned integer.

Exception response:
Except for broadcast messages, the AC drive is been expected to return a normal
response after receiving command messages from the master device. The following
depicts the conditions that no normal response is replied to the master device.
The AC drive does not receive the messages due to a communication error; thus, the
AC drive has no response. The master device will eventually process a timeout
condition.
The AC drive receives the messages without a communication error, but cannot handle
it, an exception response will return to the master device and an error message “CExx”
will display on the keypad of AC drive. The xx of “CExx” is a decimal code equal to the
exception code that will describe below.
In the exception response, the most significant bit of the original command code is set to
1, and an exception code explains the condition that caused the exception is returned.

MAINTENANCE AND INSPECTIONS
Modern AC drives are based on solid state electronics technology, preventive maintenance is
required to operate this AC drive in its optimal condition, and to ensure a long life. It is
recommended to perform a monthly check up of the AC drive by a qualified technician.
Before the check up, always turn off the AC Input Power to the unit. Wait at least 2 minutes
after all display lamps have gone out, and then confirm that the capacitors have fully
discharged by measuring the voltage between B1 and Ground using a multimeter set to
measure DC.
6.1 Periodic Inspection
Basic check up items to detect if there were any abnormality during the operation.
1. Whether the motors are operating as expected.
2.
3.
4.
5.
Whether the installation environment is abnormal.
Whether the cooling system is operating as expected.
Whether any irregular vibration or sound occurred during the operation.
Whether the motors are overheated during the operation.
6. Always check the input voltage of the AC drive with Voltmeter.
6.2 Periodic Maintenance
!
1.
WARNING! Disconnecting AC power before processing!
Tighten and reinforce the screws of the AC drive if necessary, cause it may loose due to
the vibration or changing of temperatures.
2.
Whether the conductors or insulators were corroded and damaged.
3.
Check the resistance of the insulation with Mega-ohmeter.
4.
Often check and change the capacitors and relays.
5.
If use of the AC drive is discontinued for a long period of time, turn the power on at least
once every two years and confirm that it still functions properly. To confirm functionality,
disconnect the motor and energize the AC drive for 5 hours or more before attempting to
run a motor with it.
6.

Note1: The table above gives approximate wire size for the zero phase reactors but the
selection is ultimately governed by the type and diameter of cable fitted i.e. the cable
must fit through the center hole of zero phase reactors.
Note2: Only the phase conductors should pass through, not the earth core or screen.
Note3: When long motor output cables are used an output zero phase reactor may be
required to reduce radiated emissions from the cable.
