instructions

1.2.9 Others

CAUTION

During transport or under any specific condition, the inverter may not be placed in a

halogen (fluorine, chlorine, bromine, iodine) environment. Otherwise, the inverter may

be damaged or its components will be burned out.

1.3 Precautions

1.3.1 Motor insulation inspection

When the motor is used for the first time, or reused after storing for a long time, or

in a regular inspection, the user must inspect the insulation of the motor to prevent

the poor insulation of the windings of motor from damaging the inverter. The motor

connection must be divided from the inverter during the insulation inspection. It is

recommended to use a 500 V Mega-Ohm-Meter and the insulation resistance shall

not be less than 5 MΩ.

1.3.2 Thermal protection of motor

If the rated capacity of the motor selected is not matching that of the AS500 series

inverter, especially when the rated power of the inverter is greater than that of the

motor, make sure to adjust the parameters for motor protection inside the AS500

inverter or to install a thermal relay to the motor to guarantee the protection to the

motor.

1.3.3 Motor heat and noise

Since the output voltage of the inverter is PWM wave with some harmonic, the

temperature rise, noise and vibration may increase compared with the inverter

running at power frequency.

When a conventional motor driven by an inverter is in prolonged low speed

operation, the motor temperature will rise because the heat dissipation effect of the

1-8

Cha

p

ter 1 Safet

y

instructions

motor becomes poorer. If a prolonged constant-torque low-speed operation is

required, a variable frequency motor must be selected, or forced air cooling be

provided.

1.3.4 Caution to input and output

Because the AS500 inverter outputs PWM wave, the capacitor used for improving

power factor and piezoresistance used for lightening-proof should not be installed

at the output side of the inverter. Otherwise the inverter may have transient

over-current and may be damaged.

No permission for capacitor connection at the output side of the inverter refers to

Figure 1-1.

Figure 1-1 Schematic diagram for non-permission for capacitor connection at the output side of the

inverter

If a contactor is required to be installed between the inverter input terminal and the

power supply, it is prohibited to start or stop the inverter with the contactor.

If switches like contactors are connected between the output terminal and the motor,

make sure to start and stop the inverter when the inverter has no output, it is

prohibited to pick up the contactor when the inverter is outputting, otherwise the

modules in the inverter may be damaged.

Terminals are recommended for the startup / shutdown of the inverter. The user is

absolutely not permitted to directly shut down or start up the inverter via such

switches as contactor on the input terminal of the inverter; otherwise, damages to

equipment may be caused.

instructions

1.3.5 Usage out of the Range of Rated Voltage

The AS500 series inverter shall not be used out of the specified range of operating

voltage. Otherwise, the internal components of the inverter may be damaged. If

needed, please use corresponding voltage regulation device to change the voltage.

1.3.6 Lightning Strike Protection

There are lightning over current protection devices inside the inverter, which has

certain self-protection capacity for sensing the lightning. The user should install

other lightning protection device at the front end of the inverter where lightning

strike occurs frequently.

1.3.7 Leakage protection

Quick startup or shutdown during inverter operation necessarily induces

high-frequency leakage currents, which may sometimes cause misoperation of the

leakage protection circuit. In the event of the aforesaid problems, reduce the carrier

frequency and the length of the lead-in wire appropriately; besides, the leakage

protector must be correctly installed.

Keep the following points in mind when installing a leakage protector:

 It is more proper to install the protector at the input terminal of the inverter and

behind the air circuit breaker (not a fuse circuit breaker).

 The selected leakage protector must be insensitive to higher harmonics

(sensitivity: Above 30 mA) or specially suited for inverter applications. If a common

leakage protector is selected, it must have the sensitivity above 200 mA and the

action time above 0.1 s.

1.3.8 Derating

When the ambient temperature exceeds 40 , the inverter must be derated by 1% ℃

for every increment of one degree Celsius. Also, forced external heat dissipation

must be provided.

At 1,000 m above sea level, the thinner air will deteriorate the heat dissipation effect

1-10

Shanghai Sigriner STEP Electric Co., Ltd.

Cha

p

ter 1 Safet

y

instructions

of the inverter. Therefore, the inverter must be derated by 1% for every increment of

100 m.

When the set carrier frequency exceeds the factory settings, the inverter must be

derated by 10% for every increment of 1 kHz.

For derating, please contact our company for detailed technical support.

1.3.9 About applicable motor

The inverter is applicable to asynchronous squirrel-cage motor and permanent

magnet synchronous motor. Please be sure to select the applicable inverter

according to the Nameplate of the motor.

The inverter has already been configured with default parameters which are

applicable to asynchronous squirrel-cage motor. To perform the motor parameter

identification according to the actual conditions will promote the operation effect.

The short circuit of cable or motor interior may cause the inverter alarm or to be

damaged. Therefore, perform insulation short test for the initially installed motor

and cables, and also make such test during the routine maintenance. Please make

sure that the inverter be cut from the testing parts when the test is undergoing.

4.1.2.10 AC reactor on the output side

An optional AC reactor may be used on the output side to restrain the radio

interference.

Where the cable between the inverter and the motor is long (> 30 m) or several

motors run together, because of the parasitic capacitance effect to ground by long

cable, the leakage current becomes too heavy, and the inverter may suffers from

frequent overcurrent protection, and the destruction of insulation of the motor shall

be avoided, so an output reactor shall be increased.

4.2.2 Wiring precautions

IMPORTANT

a) The connection shall conform to relevant electrical engineering standards.

b) Check the wiring and its reliability after wiring. The following items shall be

checked:

Is all wiring correct?

Have any wire clippings or screws been left inside the Inverter?

Is any screw loosened?

Does any bare wire at terminal end contact with other terminals?

c) Although AS500 is equipped with a braking unit, an external braking resistor is

still necessary. The braking resistor shall be installed between Terminal B and

Terminal 2, and not anywhere else, or the resistor and the Inverter may be

damaged.

d) The DC reactor shall be connected between Terminals 1 and 2, and the

short-circuit bar between them shall be removed.

e) When bus low-voltage running is needed, an emergency power of 200 V shall

be connected between Terminals R0 and T0, and a DC 48V shall be put between

Terminals R and S. These may be saved if no bus-voltage running is required.

f) It is recommended that the grounding wire PE of the Inverter be connected to a

special grounding terminal and the ground resistor shall have its resistance below

10 Ω.

g) The grounding cable shall be as short as possible.

h) When there is need for wiring changes after powering on, the power shall be

cut off first. Since it takes some time for the main circuit charge capacitor to

discharge, subsequent procedures may be taken only after the charging indicator

voltage drop may be calculated as follows:

Line-to-line voltage loss (V) = 3 * line resistance (Ω) * current (A)

4.3.4 Illustration of main circuit wiring

4.3.4.1 Power supply

The inverter must be grounded for protection. In view of high leakage current

(exceeding 3.5 mA), in order to comply with relevant current regulations, at least 1

piece of 10 mm2 earthing conductor or 2 pieces of earthing conductors having the

same cross sectional area with power lead shall be used.

4.3.4.2 Ground Terminal (E)/ (PE)

 It is recommended to connect the ground terminal to a specialized grounding

electrode. Reliable connection shall be ensured. The grounding resistance shall be

lower than 10 Ω.

 The grounding conductor may not be shared with welding machines or other

power devices.

 Always use a grounding conductor that complies with the technical standards on

the electrical equipment and minimize the length of the wire. Long distance

between the grounding conductor and the grounding electrode may lead to leakage

current of the Inverter which causes instability in grounding terminal potential.

 Multi-strand copper lines over 3.5 mm2 shall be used for the grounding wire. It is

recommended to use specific green-yellow grounding wires.

 It is recommended not to loop the grounding wire when more than one inverter is

to be grounded in order to avoid grounding loop.

 For the method to ground inverters more than one, see Figure 4-10.

CAUTION

Improper wiring:

If the input line voltage is applied to (U/T1, V/T2, W/T3), the inverter will be damaged.

Prior to power-on of the inverter, check the power connection.

If replacing with another inverter, please confirm all connections to the inverter complying

with the wiring instructions in this manual.

If not in accordance with this manual, death or serious injury will be caused.

4.3.4.3 +48 V DC power terminals ( 2, )

At power grid failure, storage batteries connected to Terminals ◆ 2 and

may be used to supply a direct low-voltage power to the inverter to enable low

speed running of the motor and protect the machinery from impact.

4.3.4.4 Power supply input terminals for the main circuit (R/L1, S/L2, T/L3)

A 3◆ -phase AC power supply may be connected through a breaker to any one of

Terminals R/L1, S/L2, and T/L3. The phase sequence of the input power supply is

irrelevant to the sequence of R/L1, S/L2, and T/L3.

A noise filter may be installed on the power supply side in order to reduce ◆

transmission and radiation interferences of the Inverter caused to the input power

supply. The noise filter may reduce the electromagnetic interference both from the

power line to the inverter and vice versa.

CAUTION: please use only noise filters specifically for inverters.

4.4.3 Main circuit wiring

To suppress the radiated interference from the output side of the inverter and

reinforce the anti-interference ability, the distance between them should be as large

as possible, particularly, when the cable is laid in parallel and the extended distance

is great relatively. While the signal cable has to cross the power cable, they should

be perpendicular mutually. Main circuit wiring is shown in Figures 4-19 and 4-20

Figure 4-19 Layout 1 of main circuit wiring

Figure 4-20 Layout 2 of main circuit wiring

In general, the control cable must be shielded, and the wire mesh for shielding must

be connected to the metal case of the inverter by means of the cable grips at both

ends, as shown in Figure 4-22.

Figure 4-22 Comparison of grounding methods

4.4.4 Better countermeasures against noise

To reduce noises more effectively, a noise filter shall be installed on both the input

4.4.5 Relationship between cable length and carrier frequency

If the cable linking the inverter and the motor is too long, the high-frequency

leakage current may increase due to distributed capacitance, which may trigger

over-current protection of the inverter output and thus causes negative impacts on

surrounding equipment and electrical machines. Therefore, the cable between the

inverter and the motor shall be no longer than 100 m. Please adjust carrier

frequency PO2.14 and select a noise filter and reactor for the output side according

to the following table.

Cable length 50m and shorter 100m and shorter Over100m

5.1 Run command setting

The digital operator is the basic tool of inverter operation for observing the status

and fault codes of the inverter and setting and viewing the parameters. This chapter

describes basic operations of the operator in detail.

5.1.1 Inverter run command channel

It specifies the physical channels for command receiving, startup, stop, etc. of the

inverter. Run command channels have three kinds:

Operating panel: make control by RUN, STOP, LOC/REM keys on operating panel;

Control terminal: make control by control terminals X0 ~ X7 (digital), A0 ~ A1

(analog);

Communication port: make startup and stop control by control terminals A+, B-

(RS485) through the upper machine.

Selection of run channels may be set by function code P10.01.

Caution: Prior to switching the run channels, please be sure to carry out switching

debugging, or else there will be risk of damaging equipment and personal injury!

5.1.2 Inverter frequency setting channel

Under common running mode, AS500 has four kinds of physical channels for

frequency setting, including:

command is executed, the inverter enters into shutdown state immediately.

Running state: the inverter enters into running state after receiving a run command.

5.1.4 Run modes of inverter

AS500 inverter has four kinds of run modes, sequenced by priority as follows:

Closed-loop run > Multi-speed run > Common run

Closed-loop run: closed-loop selection function becomes valid (P51.00 = 1), and

the inverter will operate in closed-loop mode; namely, PID adjustment is performed

according to setting and feedback (see P51 function codes).

Multi-speed run: in virtue of open/close of multi-function terminals (#3, 4, 5

functions), select multi-stage frequency 1 ~ 7 (P41.00 ~ P41.07) for multi-speed run.

Note: three terminals may not be all in “OFF” state; otherwise, it becomes common

run.

Common run: simple open-loop run mode.

for the AC power supply on the input side of the inverter. “U.0.0.0.0.” will be

displayed on the control panel of the inverter. If the contactor in the inverter is

normally picked up and the characters displayed by the LED digital tube change to

the set frequency, it indicates that the inverter has been successfully initialized. If

any abnormality occurs in the aforesaid power-on process, please open the air

circuit-breaker on the output side, find out the cause and rectify the fault.

5.5.2 Guide to quick debugging

This part prescribes the common but necessary debugging steps for speed control

of the AS500 series inverter in general mode on the basis of the factory settings.

5.5.2.1 Setting of common parameter in each control mode

1. Selection of control mode: select control mode according to application and

demand, referring to P10.00 “Control mode of motor” for details;

2. Selection of running command channel: refer to P10.02 “Selection of given

running command” for details;

3. Selection of given frequency channel and given setting frequency: refer to

P10.03 “Method to setting of frequency and speed” for details;

4. Correctly set P70.02 “Max frequency”, P70.00 “Upper frequency limit” and

P70.01 “Lower frequency Limit”;

5. Direction of motor rotation: To confirm the phase sequence of the motor wiring

and configure P20.09 “Phase sequence of the motor” and P71.05 “Reverse rotation

prohibited” as required by the mechanical load;

6. Acceleration/deceleration time: set P10.09 “Acceleration time” and P10.10

“Deceleration time” as long as possible to meet requirements. If the time is too

short, a great torque will be generated and damage the load, or cause an

overcurrent;

7. Startup/shutdown mode: refer to P11.00 “Startup mode” and P12.00 “Shutdown

mode” for details;

8. Parameters on motor nameplate: set P20.00 ~ P20.06 rated power, number of

poles, rated current, rated frequency, rated rotation speed, rated voltage;

9. Motor overload protection: refer to P21.01 “Motor overload protection mode”,

P21.02 “Motor sensor overload protection threshold”, P21.03 “Motor overload

protection time”, P70.04 “Output torque limitation” for details.

5.5.2.2 Quick debugging for V/F control

5.5.2.3 Quick debugging for vector control

Method to quick debugging for vector control is described in following section with

sensorless vector control without as an example. If “vector control with PG” is used,

it is required to set encoder parameters according to instruction to encoder

parameter P22 in this manual.
