1.4 Wiring between Inverter and Peripheral devices and notice
CAUTION
1. After turning OFF the main circuit power supply, do not touch the circuit
components or change any circuit components before the “CHARGE” lamps
extinguished. (It 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. Never connect the inverter output U/T1, V/T2, W/T3 to the AC source.
4. Always connect the ground lead E to ground.
5. Never apply high voltage test directly to the components within the inverter. (The
semiconductor devices are vulnerable to high voltage shock.)
6. The CMOS IC on the control board is vulnerable to ESD. Do not try to touch the
control board.
7. If Sn-03 is 7,9,11 (2-wire mode) or is 8, 10, 12 (3-wire mode), except parameter
settings of Sn-01 and Sn-02, the other parameter settings will return to their initial
settings at factory. If the inverter is initially operated in 3-wire mode (Sn-03= 8,
10, 12), the motor will rotate in CCW sense after setting changed to 2-wire mode.
(Sn-03= 7, 9, 11). Be sure that the terminals 1 and 2 are OPEN so as not to
harmful to personal or cause any potential damage to machines.
CAUTION
1. Determine the wire size for the main circuit so that the line voltage drop is within
2% of the rated voltage. If there is the possibility of excessive voltage drop due to
wire length, use a larger wire (larger diameter) suitable to the required length
2. If the length of the cable wire between the inverter and the motor exceeds 30m,
use a lower carrier frequency for PWM (adjust the parameter Cn-34). Refer to
Page 3-21

1.7 Wiring main circuit and notice
■ Main circuit wiring
The non-fusible-breaker (NFB) should be installed between the AC source and the
R/L1-S/L2-T/L3 input terminal of MA7200 inverter. The user can make his own decision
of installing electromagnetic contactor block (MCB) or not. To protect against the false
triggering of leakage-current, the user should install a leakage current breaker with
amperage sensitivity≧200mA and operation time≧0.1 sec.
Table 3 230V and 460V class ap plicab le wire size and connector
*2 : The main circuit has terminals of R/L1, S/L2, T/L3, U/T1, V/T2, W/T3, B1/P, B2/R, B2,Θ.
*3 : The control wire is the wire led to the pin terminals of control board.
*4 : In Table 3, the specified Part No. of NFB and MC are the item No. of the products of TECO. The
customer can use the same rating of similar products from other sources. To decrease the noise
interference, be sure to add R-C surge suppressor (R: 10Ω/5W, C: 0.1μF/1000VDC) at the 2
terminals of coils of electromagnetic contactor.
1-14
■ External circuit wiring precaution:
(A) Control circuit wiring:
(1) Separate the control circuit wiring from main circuit wiring (R/L1, S/L2, T/L3, U/T1,
V/T2, W/T3) and other high-power lines to avoid noise interruption.
(2) Separate the wiring for control circuit terminals RA-RB-RC (R1A-R2B-R2C) (contact
output) from wiring for terminals c~j, A01, A02, GND, DO1, DO2 , DOG 15V(or
+12V, -12V), VIN, AIN, AUX, GND, IP12, IG12, A (+), A (-), S(+) and S(-).
(3) Use the twisted-pair or shielded twisted-pair cables for control circuits to prevent
operating faults. Process the cable ends as shown in Fig. 3. The max. wiring distance
should not exceed 50 meter.

sequence.
(2) Never connect the AC power source to the output terminals U/T1, 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 a phase advancing capacitor or LC/RC noise filter to an output circuit.

‧ Determine the wire size for the main circuit so that the line voltage drop is within
2% of the rated voltage. (If there is the possibility of excessive voltage drop, use a
larger wire suitable to the required length)
‧ Installing an AC reactor
If the inverter is connected to a large-capacity power source (600kVA or more),
install an optional AC reactor on the input side of the inverter. This also improves
the power factor on the power supply side.
‧ If the cable between the inverter and the motor is 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:

MA7200 230V/460V 1~20HP model have built-in braking transistor, and can be
connected external braking resistor between B1/P and B2 when lack of braking
ability. Above 25HP models, need to connect braking unit (on ⊕ - \ of inverter)
and braking resistors (on B-P0 of braking unit).
‧ An AC reactor can be added on the power supply side if the inverter is connected to a
much larger capacity power supply system, or the inverter is within short distance
(<10m) from power supply systems, or to increase the power factor on the power
supply side.
‧ Choose the proper AC reactor according to the below list.
Note: The AC reactors are applied only to input side. Do not apply it to output side.

B.EMI SUPPRESSION ZERO PHASE CORE
)
‧ Model : JUNFOC046S -------
‧ Code No. : 4H000D0250001
‧ According to the required power rating and wire size, select the matched ferrite core to
suppress EMI noise.
‧ The ferrite core can attenuate the frequency response at high frequency range (from
100KHz to 50MHz, as shown below). It should be able to attenuate the RFI from
inverter to outside.
‧ The zero-sequence noise ferrite core can be installed either on the input side or on the
output side. The wire around the core for each phase should be winded by following
the same convention and one direction. The more winding turns the better attenuation
effect. (Without saturation). If the wire size is too big to be winded, all the wire can be
grouped and go through these several cores together in one direction.

(11) Auto Torque Boost Gain (Bn-11)
‧ The inverter can increase the output torque to compensate the load increase
automatically through the auto torque boost function. Then the output voltage will
increase. As a result, the fault trip cases can be decreased. The energy efficiency is
also improved. In the case that the wiring distance between the inverter and the
motor is too long (e.g. more than 100m), the motor torque is a little short because
of voltage drop. Increase the value of Bn-11 gradually and make sure the current
will not increase too much. Normally, no adjustment is required.

‧ The PID control function is a control system that matches a feedback value (i.e., a
detected value) to the set target value. Combining the proportional (P), integral (I)
and derivative (D) control make the control possible to achieve required response
with the constant setting and tuning procedure of proportional gain Bn-17, integral
time Bn-18 and derivative time Bn-19.
‧ See the appendix on page App.1 for “PID Parameter Setting”.
‧ Fig. 12 is a Block diagram of the inverter’s internal PID control.
‧ If both the target value and feedback value are set to 0, adjust the inverter output
frequency to zero.

(22) Timer ON_Delay Time (Bn-37)
(23) Timer OFF_Delay Time (Bn-38)
‧ The timer function is enabled when the timer function input setting (Sn-25~28=19)
and its timer function output setting (Sn-30~32=21) are set for the multi-function
input and output respectively.
‧ These inputs and outputs serve as general-purpose I/O. Setting ON/OFF delay
time (Bn-37/38) for the timer can prevent chattering of sensors, switches and so
on.
‧ When the timer function input ON times is longer than the value set for Bn-37, the
timer function output turns ON.
‧ When the timer function input OFF time is longer than the value set for Bn-38, the
timer function output turns OFF. An example is shown below.

(24) Energy Saving Gain (Bn-39)
‧ Input the energy saving command while a light load causes the inverter output
voltage to be reduced and save energy. Set this value as a percentage of the V/F
pattern. The setting range is 50~150%. The factory setting is 100% and the energy
saving function is disabled. If the energy saving gain Bn-39 is not 100%, the
energy saving function is enabled.
‧ In energy saving mode (Bn-39≠100), the output voltage will automatically
decrease and be proportional to energy saving gain Bn-39. The Bn-39 setting
should not be small so that the motor will not stall.
‧ The energy saving function is disabled in the PID close-loop control and during
acceleration and deceleration.

(1) Input Voltage Setting (Cn-01)
‧ Set inverter voltage to match power supply voltage at input side (e.g. : 200V/230V,
380V/415V/440V/460V)
(2) V/F Curve Parameter Settings (Cn-02~Cn-08)
‧ The V/F curve can be set to either one of the preset curves (setting Sn-02=0~14)
or a customer user-set curve (setting Sn-02=15).
‧ Setting Cn-02~Cn-08 can be set by the user when Sn-02 has been set to “15”.
The user-defined V/F curve can be specified through the settings of Cn-02~Cn-08
as shown in Fig. 17. The factory setting is straight line for the V/F curve.
(Cn-05=Cn-07, Cn-06 is not used) as shown below (230V/60Hz case).

Fig. 17. User-defined V/F curve
‧ In low speed operation (<3Hz), a larger torque can be generated by increasing the
slope of V/F curve. However, the motor will be hot due to over-excitation. At the
same time the inverter will be more inclined to fault. Based upon the applied load,
properly adjust the V/F curve according to the magnitude of monitored current
into the motor.
‧ The four frequency settings must satisfy the following relationship, otherwise an
error message “V/F Curve Invalid” will display.
(a)
Max. output freq.≧ Max. voltage freq. > Mid. Output freq. ≧ Min. output freq.
(Cn-02) (Cn-04) (Cn-05) (Cn-07)
(b) Max. output volt.≧ Mid. output volt. > Min. output voltage
(Cn-03) (Cn-06) (Cn-08)
‧ If Mid. Output frequency (Cn-05) = Min. output frequency (Cn-07), the setting
(Cn-06) is not effective.
(3) Motor Rated Current (Cn-09)
‧ Electronic overload thermal reference current
‧ The factory setting depends upon the capacity type of inverter (Sn-01).
‧ The setting range is 10%~200% of the inverter rated output current.
‧ Set the rated current shown on the motor name plate if not using the TECO 4-pole
motor.
3-15
(4) Motor No-Load Current (Cn-10)
‧ This setting is used as a reference value for torque compensation function.
‧ The setting range is 0~99% of the inverter rated current Cn-09 (100%).
‧ The slip compensation is enabled when the output current is greater than motor
no-load current (Cn-10). The output frequency will shift from f1 to f2 (>f1) for the
positive change of load torque. (See Fig. 18)
Slip compensation =

(5) Motor Rated Slip (Cn-11)
‧ This setting is used as a reference value for torque compensation function. See Fig.
17. The setting is 0.0~9.9% as a percentage of motor Max. voltage frequency
(Cn-04) as 100%.
‧ The setting is shown in Fig. 19 in the constant torque and constant output range. If
setting Cn-11 is zero, no slip compensation is used.
‧ There is no slip compensation in the cases when the frequency command is less
than the Min. output frequency or during regeneration.

‧ It is for torque compensation function. The default setting depends upon the
inverter capacity (Sn-01). Normally, the setting does not need to be altered. See
Table 10~11 on page 3-39.
(8) DC Injection Braking Starting Frequency (Cn-14)
(9) DC Injection Braking Current (Cn-15)
(10) DC Injection Braking Time at Stop (Cn-16)
(11) DC Injection Braking Time at Start (Cn-17)
‧ The DC injection braking function decelerates by applying a DC current to the
motor. This happens in the 2 cases:
a. DC injection braking time at start: It is effective for temporarily stopping and then
restarting, without regeneration, a motor coasting by inertia.
b. DC injection braking time at stop: It is used to prevent coasting by inertia when
the motor is not completely stopped by normal deceleration when there is a large
load. Lengthening the DC injection braking time (Cn-16) or increasing the DC
injection braking current (Cn-15) can shorten the stopping time.
‧ For the DC injection braking current (Cn-15), set the value for the current that is
output at the time of DC injection braking. DC injection braking current is set as a
percentage of inverter rated output current, with the inverter rated output current
taken as 100%.
‧ For the DC injection braking time at start (Cn-17), set the DC injection braking
operating time when the motor is started.
‧ For the DC injection braking starting frequency (Cn-14), set the frequency for
beginning DC injection braking for deceleration. If the excitation level is less than
the Min. output frequency (Cn-07), the DC injection braking will begin from Min.
output frequency.
‧ If the DC injection braking time at start (Cn-17) is 0.0, the motor starts from the
Min. output frequency and no DC injection braking are enabled.
‧ If the DC injection braking time at stop (Cn-16) is 0.0, no DC injection braking is
enabled. In this case, the inverter output will be blocked off when the output
frequency is less than the DC injection braking at start frequency (Cn-14).

(12) Frequency Command Upper Bound (Cn-18)
(13) Frequency Command Lower Bound (Cn-19)
‧ The upper and lower bounds of the frequency command are set as a percentage of
the Max. output frequency (Cn-02 as 100%), in increments of 1%.
‧ The relationship Cn-18 > Cn-19 must be abided by. If not, an error message “Freq.
Limit Setting Error” may occur.
‧ When the frequency command is zero and a run command is input, the motor
operates at the frequency command lower bound (Cn-19). The motor will not
operate, however, if the lower limit is set lower than the Min. output frequency
(Cn-07).

‧ Operation is prohibited within the jump frequency range, but changes during
acceleration and deceleration are smooth with no jump. To disable this function,
set the jump frequency 1~3 (Cn-20~Cn-22) to 0.0Hz.
‧ For the jump frequency 1~3 (Cn-20~Cn-22), set the center frequency to be
jumped.
‧ Be sure to set the jump so that Cn-20 ≥ Cn-21 ≥ Cn-22. If not, a message “Jump
frequency setting error” is displayed. For Cn-23, set the jump frequency
bandwidth. If Cn-23 is set as 0.0Hz, the jump frequency function is disabled.
(18) Number of Auto Restart Attempt (Cn-24)
‧ The fault restart function will restart the inverter even when an internal fault
occurs during inverter operation. Use this function only when continuing operation
is more important than possibly damaging the inverter.
‧ The fault restart function is effective with the following faults. With other faults,
the protective operations will engage immediately without attempting to restart
operation.
‧ The fault restart count will automatically increase upon the restart activated and
will be cleared in the following cases:
a. When the operation is normal for 10 minutes after a fault restart is performed.
b. When the fault-reset input is received after the protection operation has been
activated and the fault confirmed. (e.g., by pressing
or enable Fault reset
RESET
terminal e)
c. When the power is turned off and on again.
‧ When one of the multi-function output terminals (RA-RB-RC or R1A-R1B-R1C,
DO1, DO2 or R2A-R2C) is set to restart enabled, the output will be ON while the
fault restart function is in progress. See page 63 for the setting of (Sn-30~Sn-32).

(19) Stall Prevention Level During Acceleration (Cn-25)
(20) Stall Prevention Level During Running (Cn-26)
‧ A stall occurs if the rotor can not keep up with the rotating electromagnetic field in
the motor stator side when a large load is applied or a sudden acceleration or
deceleration is performed. In this case, the inverter should automatically adjust the
output frequency to prevent stall.
‧ The stall prevention function can be set independently for accelerating and
running.
‧ Stall Prevention During Acceleration: See Fig.23. Stop acceleration if Cn-25
setting is exceeded. Accelerate again when the current recovers.
‧ Stall Prevention During running : See Fig.24. Deceleration is started if the run stall
prevention level Cn-26 is exceeded, especially when an impact load is applied
suddenly. Accelerate again when the current level is lower than Cn-26.

‧ Cn-62, 63 are available for 74.03 and later software version only.
‧ Both Overtorque Detection Function and Undertorque Detection Function are
included in Torque Detection Function. The Overtorque Detection Function
detects excessive mechanical load from an increase of output current. The
Undertorque Detection Function detects broken fan belt from a decrease of output
current.
‧ An overtorque 1 condition is detected when the output current exceeds the Torque
Detection Level (Cn-32, Cn-62) for longer than the Torque Detection Time 1
(Cn-33, Cn-63). See Fig.25-a below.
‧ An undertorque condition is detected when the output current is lower than the
Torque Detection Level (Cn-32, Cn-62) for longer than the Torque Detection Time
(Cn-33, Cn-63). See Fig.25-b below.
‧ When Torque Detection 1 is enabled through the setting Sn-12, be sure to set
Torque Detection Level 1 (Cn-32) and Torque Detection Time 1 (Cn-33).
‧ The Multi-Function Output Terminals (Control Circuit Terminals RA-RB-RC or

(31) Speed Search Detection Level (Cn-35)
(32) Speed Search Time (Cn-36)
(33) Min. Baseblock Time (Cn-37)
(34) Speed Search V/F Curve (Cn-38)
‧ The speed search function will search the speed of a frequency coasting motor
from the frequency command or max. frequency downward. And it will restart up
smoothly from that frequency or max. frequency. It is effective in situations such
as switching from a commercial power supply to an inverter without tripping
occurred.

Fig. 26. Speed search timing chart
‧ The speed search command can be set through the multi-function contact input
terminal g ~ j (By setting the parameters Sn-25 ~ Sn-28).
If Sn-25 ~ Sn-28= 21 : Speed search is performed from Max. output frequency
and motor is coasting freely.
If Sn-25 ~ Sn-28= 22 : Speed search starts from the frequency command when
the speed search command is enabled.
‧ After the inverter output is blocked, the user should input speed search command
then enable run operation, the inverter will begin to search the motor speed after
the min. baseblock time Cn-37.
‧ Speed search operation, if the inverter output current is less than Cn-35, the
inverter will take the output frequency as the real frequency at that time. From
those values of real frequency, the inverter will accelerate or decelerate to the set
frequency according to the acceleration or deceleration time.
‧ While the speed search command is being performed, the user can slightly
decrease the setting of V/F curve (Cn-38) in order to prevent the OC protection
function enabled. Normally, the V/F curve need not be changed. (As below)
Note : 1. The speed search operation will be disabled if the speed search command is
enacted from the Max. frequency and the setting frequency. (I.e., Sn-25=20,
Sn-26=21 and multi-function input terminals g, h is used at the same time).
3-25
2. Make sure that the FWD/REV command must be performed after or at the
same time with the speed search command. A typical operation sequence is
shown below.
Ry1
Speed search command

Ry2
RWD/REV run command
3. When the speed search and DC injection braking are set, set the Min.
baseblock time (Cn-37). For the Min. baseblock time, set the time long
enough to allow the motor’s residual voltage to dissipate. If an overcurrent is
detected when starting a speed search or DC injection braking, raise the
setting Cn-37 to prevent a fault from occurring. As a result, the Cn-37 setting
cannot be set too small.
(35) Low Voltage Alarm Detection Level (Cn-39)
‧ In most cases, the default setting Cn-39 need not be changed. If an external AC
reactor is used, decrease the low voltage alarm detection level by adjusting Cn-39
setting smaller. Be sure to set a main-circuit DC voltage so that a main circuit
undervoltage is detected.
(36) Slip Compensation Primary Delay Time (Cn-40)
‧ In most cases, the setting Cn-40 need not be changed. If the motor speed is not
stable, increase the Cn-40 setting. If the speed response is slow, decrease the
setting of Cn-40.
(37) S-curve Characteristic Time at Acceleration Start (Cn-41)
(38) S-curve Characteristic Time at Acceleration End (Cn-42)
(39) S-curve Characteristic Time at Deceleration Start (Cn-43)
(40) S-curve Characteristic Time at Deceleration End (Cn-44)
‧ Using the S-curve characteristic function for acceleration and deceleration can
reduce shock to the machinery when stopping and starting. With the inverter,
S-curve characteristic time can be set respectively for beginning acceleration,
ending acceleration, beginning deceleration and ending deceleration. The relation
between these parameters is shown in Fig. 27.

(41) PG Parameter (Cn-45)
‧ The parameter is set in the unit of pulse/revolution. The factory setting is 0.1 P/R.

‧ Cn-45 and Cn-46 must meet the following relationship:
2 * Cn-45 * Cn-02
< 32767

‧ If not, an error message “Input Error” will be displayed
(43) ASR Proportion Gain 1 (Cn-47)
(44) ASR Integral Gain 1 (Cn-48)
‧ Set the proportion gain and integral time of the speed control (ASR)
(45) ASR Proportion Gain 2 (Cn-49)
(46) ASR Integral Gain 2 (Cn-50)

high-speed operation.

(47) ASR Upper Bound (Cn-51)
(48) ASR Lower Bound (Cn-52)
‧ These settings of Cn-51 and Cn-52 will limit the ASR range.
‧ This parameter set the level of detecting PG speed deviation. The value of Cn-02
is referred as 100%, the default unit setting is 1%.
(50) Overspeed Detection Level (Cn-54)
‧ Set this parameter for detecting overspeed. The value of Cn-02 is referred as 100%,
the default unit setting is 1%. Please refer to the setting of Sn-43.
(51) PID Integral Upper Bound (Cn-55)
(52) PID Primary Delay Time Constant (Cn-56)
‧ Please refer to Fig. 14 “Block diagram for PID control in inverter”
‧ The parameter Cn-55 prevents the calculated value of the integral control of PID
from exceeding the fixed amount. The value is limited within 0-109% of Max.
output frequency (100%). Increase Cn-55 will improve the integral control. If
hunting cannot be reduced by decreasing the Bn-18 or increasing Cn-56, Cn-55
has to decrease. If the setting of Cn-55 is too small, the output may not match the
target setting.
‧ The parameter Cn-56 is the low-pass filter setting for PID control output. If the
viscous friction of the mechanical system is high, or if the rigidity is low, causing
the mechanical system to oscillate, increase the setting Cn-56 so that it is higher
than the oscillation period. It will decrease the responsiveness, but it will prevent
the oscillation.
(53) Motor Line-to-Line Resistance R1 (Cn-57)
‧ Set the motor’s terminal resistance (including the motor external cable resistance)
in Ω unit.
‧ The default setting depends upon the type of inverter (but do not include the motor
external motor cable resistance).
3-28
‧ This value will be automatically set during autotuning. See “Motor parameter
autotuning selection” on page 3-73.
‧ Increase the setting when the generating torque is not large enough at low speed.
‧ Decrease the setting when the generating torque is extremely high and cause
overcurrent trip at low speed.
(54) Motor Rotor Equivalent Resistance R2 (Cn-58)
‧ Set the motor’s rotor Y-equivalent model resistance in unit.
‧ The default setting depends upon the type of inverter. Normally this value isn’t
shown on the motor’s nameplate, so it might be necessary to contact motor
manufactor.
‧ This value will be automatically set during autotuning. See “Motor parameter
autotuning selection” on page 3-73.
(55) Motor Leakage Inductance Ls (Cn-59)
‧ Set the motor’s rotor Y-equivalent model leakage inductance in mH unit.
‧ The default setting depends upon the type of inverter.
‧ This value will be automatically set during autotuning. See “Motor parameter
autotuning selection” on page 3-73.
(56) Motor Mutual Inductance Lm (Cn-60)
‧ Set the motor Y-equivalent model mutual inductance in mH unit.
‧ The default setting depends upon the type of inverter.
‧ This value will be automatically set during autotuning. See “Motor parameter
autotuning selection” on page 3-73.

(57)Slip Compensation Gain (Cn-61)
‧ The parameter Cn-61 improves speed accuracy while operating with a load.
‧ Usually, the setting Cn-61 need not be changed. Adjust the setting if the speed
accuracy is needed to improve.
‧ When actual speed is low, increase the set value.
‧ When actual speed is high, decrease the set value.

(3) Inverter capacity selection (Sn-01)
‧ The inverter capacity has already been set at factory according to the following
tables. Whenever the control board is replaced, the setting Sn-01 must be set again
according to the following tables.
‧ Whenever the setting Sn-01 has been changed, the inverter system parameter
settings should be changed based upon the constant torque (CT) load (setting of
Sn-61= 0) or variable torque (VT) load (Sn-61= 1).
*1 Use the variable torque patterns when there is a quadratic or cubic relationship between the speed
and load, such as in fan or pump applications. The user can properly choose the desired (V/f)
patterns (Sn-02=04, 05, 06, or 07) based upon the load torque characteristics.
*2 In the fan or pump applications, the load torque have a quadratic or cubic relationship between
the speed and load. The inverter capacity rating can be increased to a value that doubles its own
specified capacity rating in some special case. But, due to the real hardware limitation, 230V 1HP,
2HP, 3HP, 10HP, 25HP, 40HP and 460V 1HP, 2HP, 3HP, 30HP, 50HP can not be adapted any
larger capacity.
(4) V/F curve selection (Sn-02)
‧ Set the inverter input voltage (Cn-01) first to match the power supply voltage. The
V/f curve can be set to ant of the following.
Sn-02 = 00~14: one of 15 pre-set curve patterns
= 15: V/F pattern can be set by the user through setting of Cn-01~Cn-08

‧ Initialized setting of parameter (Sn-03= 7~12)
Except the parameter of Sn-01~02 and Sn-61, the parameter groups of An-□□,
Bn-□□, Cn-□□ and Sn-□□ can be initialized as factory setting according to
the different input voltage. At the same time, the terminal g~j can be set as
2-wire or 3-wire operation mode under different setting of Sn-03. Please see
2-/3-wire operation mode on page 3-53.
(6) Run Source Selection (Sn-04)
‧ The parameter is used to select the source of run command.
Sn-04 = 0 : digital operator
= 1 : control circuit terminal
= 2 : RS-485 communication
‧ If Sn-04 is set as 1, the run source is from the control circuit terminal. Under the
initial setting of 2-wire operation (through setting of Sn-03=7 or 9 or 11), the run
source will be FWD/STOP, REV/STOP.
‧ If Sn-04 is set as 1, the run source is from the control circuit terminal. Under the
initial setting of 3-wire operation (through setting of Sn-03=8 or 10 or 12), the run
source will be RUN, STOP, FWD/ REV.
‧ For more details, see “2-/3- wire operation” on page 3-53.
(7) Frequency Command Setting Method Selection (Sn-05)
‧ The parameter is used to select the source of frequency command.
Sn-05 = 0 : digital operator
= 1 : control circuit terminal
= 2 : RS-485 communication
(8) Stopping Method Selection (Sn-06)
‧ Setting the stopping method used when a stop command is executed.

‧ After the stop command is input and the minimum baseblock time (Cn-37) has
elapsed, DC injection braking is applied and the motor stopped.
‧ The DC injection braking time depends upon the output frequency when the stop
command is input and the “DC injection time at stop” setting (Cn-16) as shown in
Fig. 31.
‧ Lengthen the minimum baseblock time (Cn-37) when an overcurrent (OC) occurs
during stopping. When the power to an induction motor is turned OFF, the
counter-electromotive force generated by the residual magnetic field in the motor
can cause an overcurrent to be detected when DC injection braking stop is applied.

(12) Frequency Command Characteristics Selection (Sn-10)
30.16 previous or later version set Sn-68=–0––
The positive and negative characteristics of analog frequency command (0~10V/
4~20mA) is as follow diagram:
‧ The parameter Sn-69 and settings 5-8 of Sn-12 are available for 74.03 and later
software versions.
‧ The inverter supports 2 sets of torque detection function. Each of them can set as

‧ Please refer to “Stall prevention level during acceleration” on page 3-20.
(18) Stall Prevention Selection During Deceleration (Sn-15)
‧ If external braking resistor unit is installed, the Sn-15 setting must be disabled
(Sn-15= 0).
‧ If no external braking resistor unit is installed, the inverter can provide about 20%
regenerative braking torque. If the load inertia is so large that it exceeds the
regenerative braking torque, the parameter Sn-15 is set as “1”. When setting
Sn-15= 1 (enabled) is selected, the deceleration time (Bn-02 or Bn-04) is extended
so that a main circuit overvoltage does not occur.

Sn-16 = 0 : Disabled (Stall may occur when a large load is applied)
= 1 : Enabled (Deceleration will start if the motor current is larger than the
stall prevention level during running and continues for more than
100ms. The motor is accelerated back to the reference frequency
again when the current falls below this level Cn-26).
‧ Please refer to “Stall prevention level during running” on page 3-20.
(20) Operation Selection at Fault Contact during Fault Retrying (Sn-17)
Sn-17 = 0 : Do not output fault restart. (The fault contact does not work)
= 1 : Output fault restart. (The fault contact operates)
‧ Please refer to “Number of auto restart attempt” on page 3-19.
(21) Operation Selection at Power Loss (Sn-18)
‧ This parameter specifies the processing to be performed when a momentary power
loss occurs (within 2 sec)
Sn-18 = 0 : When power loss ride through is enabled, operation will be restarted
after a speed search envoked if the power is restored within the
allowed time.
= 1 : When power loss ride-through is disabled the inverter will stop after a
momentary power loss. An undervoltage fault will be detected then. If
the power is interrupted for more than 2 seconds, the fault contact
output will operate and the motor will coast to stop.
(22) Zero Speed Braking Selection (Sn-19)
‧ The run-source and frequency command is input from control circuit under the
setting of Sn-04=1 & Sn-05=1, If Sn-19 is enabled, the blocking torque will be
generated in DC-braking mode when the frequency command is 0V and
forward –run source is “ON”.
‧ A time-chart shows the above action as below. The zero-braking selection Sn-19 is
set to 1 and the DC-braking current Cn-15 is limited within 20% of rated current.

(25) Detection Mode Selection of External Fault (Sn-22)
‧ An external fault is detected (at terminal e), the following operation will be
performed based upon the setting of Sn-22
Sn-22 = 0 : Decelerate to stop with the specified deceleration time Bn-02.
= 1 : Coast to stop.
= 2 : Decelerate to stop with the specified deceleration time Bn-04.
= 3 : Continue running with no regard of external fault.
overload is detected according to the characteristic curves of
protection operating time. vs. motor rated current setting (Cn-09).
Sn-23 = 1 : The overload is detected according to the standard motor cold start
curve.
= 2 : The overload is detected according to the standard motor hot start curve.
= 3 : The overload is detected according to the specific motor cold start curve.
= 4 : The overload is detected according to the specific motor hot start curve.
‧ Disable the motor protection function (setting 0) when 2 or more motors are
connected to a single inverter. Use another method to provide overload protection
separately to each motor, such as connecting a thermal overload relay to the power
line of each motor.
‧ The motor overload protection function should be set as Sn-23= 2 or 4 (hot start
protection characteristic curve) when the power supply is turned on or off
frequently, because the thermal values is reset each time when the power is turned
off.
‧ For the motor without forced cooling fan, the heat dissipation capability is lower
when in the low speed operation. The setting Sn-23 can be either ‘1’ or ‘2’.
‧ For the motor with forced cooling fan, the heat dissipation capability is not
dependent upon the rotating speed. The setting Sn-23 can be either ‘3’ or ‘4’.
‧ To protect the motor from overload by use of electronic overload protection, be
sure to set the parameter Cn-09 according to the rated current value shown on the
motor nameplate.

(27) Frequency Characteristics Command Selection at External Analog Input Terminal
(Sn-24)
Sn-24 = 0 : Frequency command is input at VIN terminal (0~10V)
= 1 : Frequency command is input at AIN terminal (4~20mA)
= 2 : Frequency command is the addition (VIN + AIN) at VIN (0~10V) and
AIN (4~20mA) terminal.
= 3 : Frequency command is the combination (VIN - AIN) at VIN (0~10V)
and AIN (4~20mA) terminal. If the value (VIN - AIN) is negative, the
reference command will take ‘0’ as a result.
‧ On inverter with 4P101C01301control board, if Sn-68=–1––and Sn-05=1 VIN
allowing input ±10V, set Sn-24 to select main frequency:
Sn-24 = 0 : frequency command is controlled by VIN(-10~+10V) input.
(Corresponding main frequency: -10V ~ +10V→ Reverse frequency
100% ~ forward frequency100%)
= 1 : frequency command in controlled by AIN(4~20mA) input.
(the status of forward/ reverse is set by user)
= 2 : frequency command is controlled by VIN and AIN, the sum of both
(VIN + AIN).
= 3 : frequency command is controlled by VIN and AIN, the balance of
both (VIN - AIN).
(When (VIN + AIN) < 0 or (VIN - AIN) < 0, main frequency switched
to reverse status.
Sn-24 = 0、2、3, forward or reverse is control by main frequency command polar.

‧ Forward/Reverse Change (setting : 00)
‧ Under 3-wire initialization mode (Sn-03= 8 or 10 or 12),the multi-function
input terminals g~j have setting “00”, the inverter will be in the 3-wire mode
operation. As shown in Fig. 37, the Forward/Reverse change mode is set at the
terminal g.
‧ Under a standard 2-wire initialization mode as shown in Fig. 39(a), S1 and S2
can not be both “ON” at the same time.
When S1= “ON” and S2= “OFF”, the motor is FWD running. When S1=”OFF”
and S2= “ON”, the motor is REV running. When S1= “OFF” and S2= “OFF”, the
motor stops running.
‧ When Sn-25= ‘01’, the 2-wire operation mode has its self-sustaining function.
Only through the multi-function input terminalg, the operator can stop the
inverter after pressing the “STOP” key as shown in Fig. 39(b). As shown in Fig.
39(b), the switches S1, S2 and S3 do not need to be the self-sustaining switches.
When S1 is depressed “ON”, the motor will be forward running. After S3 is
depressed “ON”, the motor will stop. When S2 is depressed “ON”, the motor
will be reverse running. After S3 is depressed “ON”, the motor will stop.

*1 When the parameter Sn-05= 0, the reference command is input by the setting of An-01.
Instead, when the parameter Sn-05= 1, the reference command is input from analog
command through the terminal VIN and AIN.
*2 If the parameter Sn-29= 0, the auxiliary frequency (the 2nd step frequency setting: AUX
frequency) is input from the AUX terminal. If the parameter Sn-29 ≠ 0, the 2nd step
frequency setting is determined by the parameter of An-02.
‧ Acceleration Time And Deceleration Time Change (Setting : 07)
‧ The acceleration time and deceleration time can be changed through the control
circuit terminal g~j as described on page 3-4.
‧ External Baseblock (A Contact) (Setting : 08)
‧ External Baseblock (B Contact) (Setting : 09)
‧ With either of these settings, the multi-function input terminal controls its
inverter baseblock operation.
‧ During running: As an external baseblock signal is detected, the digital operator
will display a “B.B. Alarm”. Then, the inverter output is blocked. After the
baseblock signal is cleared, the motor will resume running according to its then
reference signal.
‧ During deceleration : An external baseblock signal is input, the digital operator
will display “ B.B. Alarm”, the inverter is blocked from output and the output
frequency will drop to zero. The motor will then coast to stop freely. After this
external baseblock signal is cleared, the inverter will stay in stop mode.
‧ Acceleration and Deceleration Ramp Hold (Setting : 10)
‧ With this setting, the signal of Acceleration/deceleration ramp hold (input from
the multi-function input terminals) will pause the Acceleration/deceleration of
motor and maintain the then output frequency. The motor will coast to stop if an
OFF command is input while the acceleration / deceleration ramp hold input is
ON, the then output frequency will be memorized and the command of
Acceleration/deceleration ramp hold is released.

‧ Inverter Overheat Alarm (Setting : 11)
‧ When the inverter detects a overheat signal “ON”, the digital operator will
change its display as “Overheat Alarm”. And the inverter still maintains its
operation. When the overheat signal is “OFF”, the digital operator will restore
its previous display automatically. No RESET-key pressing is required.
‧ FJOG Command (Setting : 12)
‧ RJOG Command (Setting : 13)
‧ The jogging can be performed in forward or reverse rotation.
Setting = 12: FJOG command “ON”: Run forward at the jog frequency (An-17).
= 13: RJOG command “ON”: Run reverse at the jog frequency (An-17).
‧ The forward jog and reverse jog commands have priority over other frequency
command commands.
‧ The inverter will stop running with the stopping method set by the setting of
Sn-06 if the forward jog and reverse jog commands are both ON for more than
500 ms.
‧ PID Integral Reset (Setting : 14)
‧ In the application of PID control, the integral can be reset to zero (ground)
through the multi-function input terminal g~j (Sn-25~28= 14).
‧ PID Control Invalid (Setting : 15)
OFF PID control valid (close-loop)
ON PID control invalid (open-loop)
‧ This setting can be used in the changeover of test run. To disable the PID
function (PID control invalid is “ON”),an open-loop operation or jog operation
can be performed in the test. The system can be set up properly after some test
runs. Then, the system can be changed into PID control mode. Moreover, if the
feedback signal is not usable, the PID function is disabled through this setting.
‧ The setting of Sn-64 can be used to enable or disable the PID function.
‧ External Fault Contact A (Setting : 16)
‧ External Fault Contact B (Setting : 17)
‧ The external fault input terminal is set to “ON”, an external fault then occurs. If
the external input terminal h is set for the external fault input terminal use, a
message of “Fault Ext. Fault 6” will be displayed.
‧ There are 5 terminal to be assigned as external fault inputs, they are terminal e,
g, h, i, j
‧ When an external fault occurs, the inverter will be blocked from output and the
motor will coast to stop.
