4.4 Wiring the main circuits
4.4.1 Wiring at the side of power supply
●4.4.1.1 Circuit breaker
It is necessary to connect a circuit breaker which is compatible with the capacity of
inverter between 3ph AC power supply and power input terminals (R, S and T). The
CHV180 series frequency inverter special for elevator Wiring
.16.
capacity of breaker is 1.5~2 times to the rated current of inverter. Please refer to the
chapter of Specifications of Breaker, Cable, and Contactor for details.
●4.4.1.2 Contactor
In order to cut off the input power effectively when something is wrong in the system,
contactor should be installed at the input side to control the ON-OFF of the main circuit
power supply.
●4.4.1.3 AC reactor
In order to prevent the rectifier damage result from the large current, AC reactor should
be installed at the input side. It can also prevent rectifier from sudden variation of
power voltage or harmonic generated by phase-control load.
●Input EMC filter
The surrounding device may be disturbed by the cables when the inverter is working.
EMC filter can minimize the interference. Just like the following figure.
Figure 4.7 Wiring at input side.
4.4.2 Wiring for inverter
●4.4.2.1 DC reactor
CHV180 inverters (18.5kW~30kW) are equipped with internal DC reactors for the
improvement of power factors and the avoidance of damage from high input current to
the rectifying components because of the high-capacity transformer. The device can
also cease the damage to the rectifying components which are caused by supply net
voltage transients and harmonic waves of the loads.
●4.4.2.2 Braking unit and braking resistor
Inverters of 15kW and below have built-in braking unit. In order to dissipate the
regenerative energy generated by dynamic braking, the braking resistor should be
CHV180 series frequency inverter special for elevator Wiring
.17.
installed at (+) and PB terminals. The wire length of braking resistor should be less than
5m.
• Inverters of 18.5kW and above need connect external braking unit which should be
installed at (+) and (-) terminals. The cable between inverter and braking unit should be
less than 5m. The cable between braking unit and braking resistor should be less than
10m.
•The temperature of the braking resistor will increase because of the released energy.
Safety protection and good ventilation is recommended during the installation. If the
braking unit is needed, (+) and (-) terminal of the braking correspond to the (+) and (-)
terminal of the inverter and the braking resistor is connected to the terminal of BR1 and
BR2.
Note: Be sure that the electric polarity of (+) (-) terminals is right; it is not allowed to
connect (+) with (-) terminals directly, Otherwise damage or fire could occur.
4.4.3 Wiring at motor side of main circuit
●4.4.3.1 Output reactor
If the distance between the inverter and the motor is longer than 50m, frequent
overcurrent protection may occur to the inverter because of high leakage current
caused by parasitic capacitance effects from the long cables to the ground. In order to
avoid the damage of the motor insulation, it is necessary to add reactor compensation.
●4.4.3.2 Output EMC filter
EMC filter can minimize the radio noise cause by the cables between the inverter and
the motor and the leakage current of the conducting wires, which is illustrated as
below:
Figure 4.8 Wiring at motor side.
4.4.4 Wiring of regenerative unit
Regenerative unit is used for putting the electricity generated by braking of motor to
the grid. Compared with traditional 3 phase inverse parallel bridge type rectifier unit,
regenerative unit uses IGBT so that the total harmonic distortion (THD) is less than 4%.
Regenerative unit is widely used for centrifugal and hoisting equipment. Please refer to
The Manual of Regenerative Units of RBU Series for details.

insurance of safety and avoidance of electrical shock and fire. It is apporiate to use
thick and short multiple copper core wires whose sectional area is larger than 3.5m ㎡.
It is not recommended to use the public earth wire; otherwise, the grounding wires may
complete the circuit.
4.5 Wiring control circuit terminals
4.5.1 Precautions
Use shielded or twisted-pair cables to connect control terminals.
Connect the ground terminal (PE) with shield wire.
The cable connected to the control terminal should leave away from the main
circuit and heavy current circuits (including power supply cable, motor cable,
relay and contactor connecting cable) at least 20cm and parallel wiring should be
avoided. It is suggested to apply perpendicular wiring to prevent inverter
malfunction caused by external interference.

4.6 Installation guidline to EMC compliance
4.6.1 General knowledge of EMC
EMC is the abbreviation of electromagnetic compatibility, which means the device or
system has the ability to work normally in the electromagnetic environment and will not
generate any electromagnetic interference to other equipments.
EMC includes two subjects: electromagnetic interference and electromagnetic
anti-jamming.
According to the transmission mode, Electromagnetic interference can be divided into
two categories: conducted interference and radiated interference.
Conducted interference is the interference transmitted by conductor. Therefore, any
conductors (such as wire, transmission line, inductor, capacitor and so on) are the
transmission channels of the interference.
Radiated interference is the interference transmitted in electromagnetic wave, and the
energy is inverse proportional to the square of distance.
Three necessary conditions or essentials of electromagnetic interference are:
interference source, transmission channel and sensitive receiver. For customers, the
solution of EMC problem is mainly in transmission channel because of the device
attribute of disturbance source and receiver can not be changed.
4.6.2 EMC features of inverter
Like other electric or electronic devices, inverter is not only an electromagnetic
interference source but also an electromagnetic receiver. The operating principle of
inverter determines that it can produce certain electromagnetic interference noise. And
the same time inverter should be designed with certain anti-jamming ability to ensure the
CHV180 series frequency inverter special for elevator Wiring
.21.
smooth working in certain electromagnetic environment. The following is its EMC
features:
Input current is non-sine wave. The input current includes large amount of
high-harmonic waves that can cause electromagnetic interference, decrease the grid
power factor and increase the line loss.
Output voltage is high frequency PMW wave, which can increase the
temperature rise and shorten the life of motor. And the leakage current will also
increase, which can lead to the leakage protection device malfunction and
generate strong electromagnetic interference to influence the reliability of other
electric devices.
As the electromagnetic receiver, too strong interference will damage the inverter
and influence the normal using of customers.
In the system, EMS and EMI of inverter coexist. Decrease the EMI of inverter
can increase its EMS ability.
4.6.3 EMC Installation Guideline
In order to ensure all electric devices in the same system to work smoothly, this section,
based on EMC features of inverter, introduces EMC installation process in several
aspects of application (noise control, site wiring, grounding, leakage current and power
supply filter). The good effective of EMC will depend on the good effective of all of these
five aspects.
4.6.3.1 Noise control
All the connections to the control terminals must use shielded wire. And the shield layer
of the wire must ground near the wire entrance of inverter. The ground mode is 360
degree annular connection formed by cable clips. It is strictly prohibitive to connect the
twisted shielding layer to the ground of inverter, which greatly decreases or loses the
shielding effect.
Connect inverter and motor with the shielded wire or the separated cable tray. One side
of shield layer of shielded wire or metal cover of separated cable tray should connect to
ground, and the other side should connect to the motor cover. Installing an EMC filter
can reduce the electromagnetic noise greatly.
4.6.3.2 Site wiring
Power supply wiring: the power should be separated supplied from electrical transformer.
Normally it is 5 core wires, three of which are fire wires, one of which is the neutral wire,
and one of which is the ground wire. It is strictly prohibitive to use the same line to be
both the neutral wire and the ground wire
CHV180 series frequency inverter special for elevator Wiring
.22.
Device categorization: there are different electric devices contained in one control
cabinet, such as inverter, filter, PLC and instrument etc, which have different ability of
emitting and withstanding electromagnetic noise. Therefore, it needs to categorize these
devices into strong noise device and noise sensitive device. The same kinds of device
should be placed in the same area, and the distance between devices of different
category should be more than 20cm.
Wire Arrangement inside the control cabinet: there are signal wire (light current) and
power cable (strong current) in one cabinet. For the inverter, the power cables are
categorized into input cable and output cable. Signal wires can be easily disturbed by
power cables to make the equipment malfunction. Therefore when wiring, signal cables
and power cables should be arranged in different area. It is strictly prohibitive to arrange
them in parallel or interlacement at a close distance (less than 20cm) or tie them
together. If the signal wires have to cross the power cables, they should be arranged in
90 angles. Power input and output cables should not either be arranged in interlacement
or tied together, especially when installed the EMC filter. Otherwise the distributed
capacitances of its input and output power cable can be coupling each other to make the
EMC filter out of function.
4.6.3.3 Grounding
Inverter must be ground safely when in operation. Grounding enjoys priority in all EMC
methods because it does not only ensure the safety of equipment and persons, but also
is the simplest, most effective and lowest cost solution for EMC problems.
Grounding has three categories: special pole grounding, common pole grounding and
series-wound grounding. Different control system should use special pole grounding,
and different devices in the same control system should use common pole grounding,
and different devices connected by same power cable should use series-wound
grounding.
4.6.3.2 Leakage Current
Leakage current includes line-to-line leakage current and over-ground leakage current.
Its value depends on distributed capacitances and carrier frequency of inverter. The
over-ground leakage current, which is the current passing through the common ground
wire, can not only flow into inverter system but also other devices. It also can make
leakage current circuit breaker, relay or other devices malfunction. The value of
line-to-line leakage current, which means the leakage current passing through
distributed capacitors of input output wire, depends on the carrier frequency of inverter,
the length and section areas of motor cables. The higher carrier frequency of inverter,
CHV180 series frequency inverter special for elevator Wiring
.23.
the longer of the motor cable and/or the bigger cable section area, the larger leakage
current will occur.
Countermeasure:
Decreasing the carrier frequency can effectively decrease the leakage current. In the
case of motor cable is relatively long (longer than 50m), it is necessary to install AC
reactor or sinusoidal wave filter at the output side, and when it is even longer, it is
necessary to install one reactor at every certain distance.
4.6.3.5 EMC Filter
EMC filter has a great effect of electromagnetic decoupling, so it is preferred for
customer to install it.
For inverter, noise filter has following categories:
Noise filter installed at the input side of inverter;
Install noise isolation for other equipment by means of isolation transformer or
power filter.
4.6.4 If user install inverter and EMI filter according to the installation guideline, we
believe inverter system comply with following compliance.

5.2.4 Motor parameter autotune
If “Sensorless Vector Control” or “Vector Control with PG” mode is chosen, motor
nameplate parameters must be input correctly as the autotuning is based on it. The
performance of vector control depends on the parameters of motor strongly, so to
achieve excellent performance, firstly must obtain the parameter of motor exactly.
This function is not the same between synchronous motor and asynchronous motor, for
details please refer to the description of function code P0.08.
The procedure of motor parameter autotuning is as follows:
Firstly, choose keypad command as the run command source (P0.01).

high speed control accuracy and speedy dynamic response.
2: V/F control: It is suitable for the low-end elevator which requires lower accuracy or is
used for debugging.
Note:
When selecting the vector control, it is necessary to set the nameplate parameters and
encoder parameters correctly and complete the autotuning before running to get right
motor parameters (for synchronous motor, it is the pole position angle). Right
parameters are the assurance for high performance of vector control.

The advantage of high carrier frequency: ideal current waveform, little current
harmonic wave and motor noise.
The disadvantage of high carrier frequency: increasing the switch loss, increasing
inverter temperature and the impact to the output capacity. The inverter needs to
derate on high carrier frequency. At the same time, the leakage and electrical magnetic
interference will increase.
Applying low carrier frequency is contrary to the above, too low carrier frequency will
cause unstable running, torque decreasing and surge.
The manufacturer has set a reasonable carrier frequency when the inverter is in
factory. In general, users do not need to change the parameter.
When the frequency used exceeds the default carrier frequency, the inverter needs to
derate 20% for each additional 1k carrier frequency.

2: Static autotuning:
When performing static autotuning, If it is difficult to disconnect the load, static autotuning
is recommended,and choose the right motor style, input parameters (P2.04~P2.08) on
the nameplate of motor. For asynchronous motor, the stator resistor, rotor resistor,

leakage inductance of motor can be detected and the mutual inductance and current
without load will not be detected by static autotuning.If needed, user should input
suitable value according to experience.
For synchronous motor, the self-learning current (P4.10) is set to get the magnetic pole
initial position (P4.03).
Note:
Correct the zero-bias value of encoder (P4.08 and P4.09) which is displayed
by Pb.06 and Pb.07 when it is not connected to the encoder.
The direction of encoder (P4.02) must be right.When the inverter is
forwarding, the motor is counterclockwise rotation seen from motor shaft
side, and the direction of encoder is set to be forward.
When autotuning, the actual current (Pb.03) should be between 80.0% and
110%, or adjust P4.10.
Continuous autotuning for 3 times, if the deviation of each magnetic pole
position is less than 10 degrees, it shows the autotuning is right, otherwise if
the magnetic pole is more than 10 degrees, it must be reautotuned.
Static autotuning is valid for SIN/COS encoder, and rotation autotuning is
suitable for UVW encoder.

P1.14 is the initial speed when the inverter starts. If the setting speed is less than start
speed, the output frequency is 0 when running. Only when the setting speed is greater
than or equal to start speed, the inverter will start with start speed, and run according
to S-curve. If setting a right value, overcome static friction, and reduce shock at
starting. P1.15 is the duration time with starting speed in the process of starting.

detection
The above function codes will be valid after the forced deceleration switch input is
selected, the effect of forced deceleration is to prevent elevator from top-hitting or
bottom-clashing in the process of up or down running. There is only one group forced
deceleration switch in low speed elevator, and there are two or three groups forced
deceleration switches in the high speed elevator. The installation of sketch map is as

Figure 6.8 Installation sketch of forced deceleration switch.
For example, when the elevator is running up close to top, forced deceleration switch 3
will act, if the checked running speed is greater than P1.28XP0.02 at this time, elevator
will decelerate at the value of P1.27 to 0, The detailed curve is as follow:

Feedback terminals signal of forced deceleration switch action is effective.
During run-up process, it comes across up-forcing switch, or during run-down
process, it comes across down-forcing switch.
Current running speed is greater than the detected speed of corresponding
forced deceleration switch, if not; the inverter will keep the current running state.
After the forcing decelerating action, the speed will be reduced continuously with
P1.23, P1.25, and P1.27 until 0.
Note:
1)The priority of forced deceleration is only less than the priority of forcing
slow–down to stop, the priority is like this: forced deceleration 1 > forced
deceleration 2 > forced deceleration 3.
2) The 100% of forced deceleration detection value is corresponding with
elevator rated speed (P0.02).
3) It will not response the forced deceleration during motor autotuning.

1: For normal motor (within the function of low speed compensation), the lower the
speed, the poorer the cooling effect. Based on this reason, if output frequency is lower
than 30Hz, inverter will reduce the motor overload protection threshold to prevent normal
motor from overheat.
2: For variable frequency motor (without the function of low speed compensation),As the
cooling effect of variable frequency motor has nothing to do with running speed, it is not

Figure 7.8 Wiring terminals in asynchronous PG card.
Among them, +12V and COM1 are the power supply output for the encoder; TERA+,
TERA-, TERB+ and TERB- are the input terminal for the encoder; TER-OA, TER-OB
and COM1 are the output terminal for frequency division signal and there is no PE in
the internal of the card, so the user can ground by themselves during use.
The frequency coefficient of asynchronous PG card is determined by the DIP switch on
the card. There are 8 switches and the frequency coefficient is decided by the shown
binary figures that are added by 1. ” 1” on the switch s the low bit and “8” is the high bit.
When the DIP is switched to ON, the bit is valid, reverse it is “0”.

The signal wire of the PG card should be routed separately from the power lines.
Please select the shield cables as the PG signal wire for the avoidance of encoder
signal.
The shield layer of the encoder cables should be founded with one end (for example,
the PE end of the inverter) for the avoidance of the signal interference.
If the frequency division output of the PG card is connected with the user power supply,
the voltage is less than 24V, otherwise, the PG card may be damaged.

Note:
1) The installation position and method of synchronous motor PG card are the
same as that of the asynchronous motor PG card, but the contact pin has two
lines, the contact pin of asynchronous motor PG card is only one line(the below
line of CN9).
2) The dimension of SIN/COS type synchronous PG is consistent with UVW type
PG card only without dial switching for frequency division.
3) The PG card of asynchronous motor is used in all of CHV series inverters, but
the PG card of synchronous motor is only used to CHV180 inverter. When user
is using the synchronous tractor, they must select the PG card of synchronous
motor.
7.4.3 Description of Terminals and Dial Switch

TER-OA, TER-OB and COM1 are the signal terminals of frequency division output.
Note: PE terminal in PG card are not grounded to the earth, so users can
grounding it by themselves.
DB15 is the port of the encoder input signal. The sequence of the ports signal is as
below:

When using the synchronous PG card, it is necessary to insert the connecting wire of
SIN/COS or UVW whose signal array is corresponding with PG card into DB15 of PG
card.
The frequency division coefficient is determined by the dial switch on the card. The dial
switch consists of 8 bits. The frequency division is decided by the value of the binary
digits (at dial switch) plus 1. The bit marked as “1” on the DIP switch is the lower binary
bit, while “8” is the higher binary bit. When the dial switch is switched to ON, the bit is
valid, indicating “1”; otherwise, it is invalid, and it is indicating “0”.
Frequency division coefficients are shown in the table below:

8.2 Common faults and solutions
Inverter may have following faults or malfunctions during operation, please refer to the
following solutions.
No display after power on:
Inspect whether the voltage of power supply is the same as the inverter rated
voltage or not with multi-meter. If the power supply has problem, inspect and solve
it.
Inspect whether the three-phase rectify bridge is in good condition or not. If the
rectification bridge is burst out, ask for support.
Check the CHARGE light. If the light is off, the fault is mainly in the rectify bridge or
the buffer resistor. If the light is on, the fault may be lies in the switching power
supply. Please ask for support.
Power supply air switch trips off when power on:
Inspect whether the input power supply is grounded or short circuit. Please solve
the problem.
Inspect whether the rectify bridge has been burnt or not. If it is damaged, ask for
support.
Motor doesn’t move after inverter running:
Inspect if there is balanced three-phase output among U, V, and W. If yes, then
motor could be damaged, or mechanically locked. Please solve it.
If the output is unbalanced or lost, the inverter drive board or the output module
may be damaged, ask for support.
The inverter displays normally when power on, but switch at the input side trips
when running:
Inspect whether the output side of inverter is short circuit. If yes, ask for support.
Inspect whether ground fault exists. If yes, solve it.
If trip happens occasionally and the distance between motor and inverter is too far,
it is recommended to install output AC reactor.

.99.
10. Communication protocol
10.1 Interfaces
RS485: asynchronous, half-duplex.
Default: 8-E-1, 19200bps. See Group PC parameter settings.
10.2 Communication modes
(1) The protocol is Modbus protocol. Besides the common register Read/Write operation,
it is supplemented with commands of parameters management.
(2) The drive is a slave in the network. It communicates in ‘point to point’ master-slave
mode. It will not respond to the command sent by the master via broadcast address.
(3) In the case of multi-drive communication or long-distance transmission, connecting a
100~120Ω resistor in parallel with the master signal line will help to enhance the
immunity to interference.
10.3 Protocol format
Modbus protocol supports both RTU and ASCII mode. The frame format is illustrated as
follows:
Modbus adopts “Big Endian” representation for data frame. This means that when a
numerical quantity larger than a byte is transmitted, the most significant byte is sent first.
RTU mode
In RTU mode, the Modbus minimum idle time between frames should be no less than
3.5 bytes. The checksum adopts CRC-16 method. All data except checksum itself sent
will be counted into the calculation. Please refer to section: CRC Check for more
information. Note that at least 3.5 bytes of Modbus idle time should be kept and the start
and end idle time need not be summed up to it.
