■ ＂WARNING＂ or “ CAUTION＂
DANGER！
1. Be sure to turn off the main circuit power before any wiring work is to conduct.
2. Do not touch the circuit or replace any component right after turning off the power
source until the ＂CHARGE＂ LED off because of the high voltage still in the
converter. (LED “Charge＂ lamp indicates that there is still some charge in the
capacitor)
3. Never connect the output terminals U, V, W to AC power supply by mistake.
4. Only authorized personnel should be permitted to perform maintenance, inspections or
parts replacement.
5. Always connect the ground lead E to ground.
6. Never apply high voltage test directly to the components within the inverter. (The
semiconductor devices are vulnerable to high voltage shock).
WARNING
1. Install a (or more) cooling fan to keep the temperature below 45 ℃, when
mounting the inverter in enclosure.
2. Never apply high voltage test directly to the components within the inverter. (The
semiconductor devices are vulnerable to high voltage shock).
3. The CMOS IC on the control board is vulnerable to Electro-Static Discharge. Do not
try to touch the control board.
4. All the parameters of the inverter have been preset at the factory. Do not change the
settings unnecessarily except the case of special application.
CAUTION
1. Prior to installation, operation, and maintenance, read this manual thoroughly and make sure to be
proceeded by qualified professional personnel.
2. Verify if the model types is same as your expectation.
3. Do not install the converter with any damage or missing part.
4. Each inverter shall be attached with QC marking. Do not install the inverter without QC marking.

2-3 Wiring between the inverter and peripheral devices and notice
1. Always use ground leads that comply with AWG standards and make sure the
length is as short as possible. (refer Table 3)
2. Always check the output voltage and maximum current of the power source if it
can handle the required power.
3. Never connect AC main circuit power supply to output terminals U/V1, V/T2 and
W/T3.
4. Make sure all the screws properly tightened/fixed together
5. The MCCB (Molded-Case Circuit Breaker) should be installed between the AC
power supply and input terminals R/L1-S/L2-T/L3 on the GHS-V8 inverter.
The user can make his own decision whether or not to install a MC (Magnetic
Contactor) block. When a ground fault interrupter is used, select the one with
no influence for high frequency. Setting current should be 200mA or above and
the operating time at 0.1 second or longer to avoid false triggering.
Grounding.
1. Always use the ground terminal (E) with a ground resistance of less than 100 ohm.
2. Never ground GHS-V8 with other devices such as welding machines, motors, and
other large-current electrical equipment, or ground pole. Run the ground lead in
separate conduit from leads for large-current electrical equipment.
3.Always use ground leads that comply with AWG standards and make sure the length
is as short as possible.
4.When using several GHS-V8 inverters side by side, it is preferable to ground each
unit separately to ground poles. However, connecting all the ground terminals of
GHS-V8 in parallel while only grounding one of the GHS-V8's to the ground pole is
also permissible. Be sure not to form a loop with the ground leads.
(a) Correct
(b) Correct
(c) Not Accept able
Wiring Main Circuit Terminals:
1. Phase rotation of input terminals R/L1, S/L2, T/L3 is available in either
direction. (Clockwise and Counter-Clockwise)
2. Never connect AC main circuit power supply to output terminals U/V1, V/T2 and
W/T3.
3. Connect the output terminals U/T1, V/T2, W/T3 to motor lead wires U/T1, V/T2,
and W/T3, respectively.
4. Check that the motor rotates forward with the forward run source. Switch over any
2 of the output terminals to each other and reconnect if the motor rotates in reverse
with the forward run source.
5. Never connect power factor correction capacitors or input side EMI/RFI filters to
GHS-V8 output.
GWAN HSIAN ELECTRIC&MACHINERY CO.,LTD

Wiring Control Circuit terminals:
1. After turning OFF the main circuit power supply, do not touch or change any
circuit components until the LED “CHARGE＂ lamp has extinguished. (LED
“Charge＂ lamp indicates that there is still some charge in the capacitor).
2. Never do wiring work or take apart the connectors in the inverter while the power
is still on.
3. Separate the control circuit leads from the main circuit leads (R/L1, S/L2, T/L3,
U/T1, V/T2, W/T3) and other power cables to prevent erroneous operation caused
by noise interference. When necessary, try to have main-circuit wire and control
circuit wire cross in 90 degree to avoid signal interference.
4. Separate the control circuit terminals leads RA-RB-RC (R1A-R2B-R2C) (contact
output) from leads to terminals ~, A01, A02, GND, DO1, DO2 (R2A-R2C),
DOG and 15V, VIN, AIN, AUX, GND, IP12, IG12, A (+), A (-).
5. Use twisted-pair or shielded twisted-pair cables for control circuits to prevent
operating faults. Process the cable ends as shown in Figure 3. The maximum wiring
distance should not exceed 150 feet.
6. When the digital multi-function output terminals connect serially to an external
relay, an anti-parallel freewheeling diode should be applied at both ends of the
relay.
7. Never apply high voltage test directly to the components within the inverter. (The
semiconductor devices are vulnerable to high voltage shock).
8. The CMOS IC on the control board is vulnerable to Electro-Static Discharge. Do
not try to touch the control board.
9. If Sn-03 is set to 3,5,7 for 2-wire operation or if Sn-03 is set to 4,6,8 for 3-wire
operation, the parameter settings will return to factory default settings. (Except for
parameter settings in Sn-01 and Sn-02, they will remain at their modified settings).
If the inverter is initially operated in 3-wire mode (Sn-03= 4,6,8), the motor will
rotate in CCW direction after setting has been changed to 2-wire mode. (Sn-03=
3,5,7). Be sure that terminals 1 and 2 are OPEN to ensure protection against
personal harm or injury and to prevent any potential damage to machines.
10. If the cable between the inverter and the motor is excessively long, the
high-frequency leakage current will increase causing the inverter output current to
increase as well. This may affect peripheral devices. To prevent this, adjust the
carrier frequency as shown below.

Example of connection between the GHS-V8 and typical peripheral devices are shown as below.
■ Power supply switch (NFB) and earth leakage breaker
‧ Refer to Table3, choose the power supply switch of proper current
rating.
‧ Do not use the NFB as the switch that the inverter is used to control
the running or stop of motor.
‧ When the earth leakage breaker installed to protect the leakage
current fault, be sure the earth leakage breaker has the sensitivity
amperage ≧ 200 mA and operation time ≧ 0.1 sec to avoid
false-triggering.
■ Electromagnetic contactor
In normal operation, you don＇t need an electromagnetic contactor.
However, you need to install an electromagnetic contactor
while in the case of sequence control through the external device or
automatically re-start after power outage.
Do not use the electromagnetic contactor as the switch that control
the operation of running or stop.
■ AC reactor
‧ The AC-Side reactor on the input AC side can be improve the power
factor and suppress the surge current.
■ Input noise filter
‧ GHS-V8 will comply with the EN55011 Class A regulation if an
input noise filter is used。
‧ Please consult with the selection guide on Appendix ＂Noise filter
at power supply side＂
■ Inverter
‧ Input power supply can be connected to any terminals or terminals
block.
‧ Please connect the ground terminal
to the site ground securely.
■ Output noise filter
‧ Install the noise filter to eliminate noise transmitted through the power
line and the inverter so that the electromagnetic conductive noise and
inductive noise can be reduced to an acceptable level.
‧ Please consult with the selection guide on Appendix“zero-phase
noise filter＂
‧
■ Induction Motor
‧ If one inverter is drive more than one motor, the inverter＇s rated
current should be much greater than the sum of total current of
motors while in operation.
‧ The inverter and the motor should connect to the ground separatedly.

1. The PID Control Function is a control system that matches
the feedback value (i.e., a detected value) to the target value.
Combining the Proportional (P), Integral (I) and Derivative
(D) control enable the PID controller to achieve required
response through the tuning procedure of PID Proportional
Gain Bn-14, PID Integral Time Bn-15 and PID Derivative
Time Bn-16.
2. Please refer to Fig 7 of “Block diagram of PID Control”.
3. To enable PID, set Sn-41=1. The detected value is obtained
through the input terminals of master speed terminals (VIN
& AIN). Its source of target value (frequency command)
can be determined/selected from 1) operator 2) RS-485 3)
AUX control terminal under the setting of Sn-05.(refer
Sn-05). Note that if the target value is from the AUX
multi-function analog terminal, the setting of Sn-29 is set as
Sn-29=11.
4. Please refer to Fig 8 ‘Response of PID control for
STEP-shape (deviation) input’ for the meaning of the
Bn-13, Bn-14, Bn-15 and Bn-16and how they work in PID
control.。
5. If both the target value and feedback value are set to 0,
make the inverter output frequency to zero by tuning the
PID offset Bias Bn-17.

Deviation = Target Value - Detected Value × Bn-13.
P’s Control Output = Deviation × Bn-14.
I’s Control Output will increase with time and the output will be equal to the deviation after time specified
by parameter Bn-15.
The parameter Cn-44 will prevent the calculated value of the Integral Control (with the Integral Time
Bn-16) in the PID Control from exceeding the fixed amount.
