Do not use 3 core cables to connect a remotely located motor to the inverter

•

When you operating Brake resistor, the motor may vibrate under the Flux braking operation. In this case, turn off the Flux braking(Pr.50).

•

Make sure that the total cable length does not exceed 665ft (202m). For inverters < =

4.0kW capacity, ensure that the total cable length does not exceed 165ft (50m).

•

Long cable runs can cause reduced motor torque in low frequency applications due to voltage drop. Long cable runs also increase a circuit’s susceptibility to stray capacitance and may trigger over-current protection devices or result in malfunction of equipment connected to the inverter.

•

Voltage drop is calculated by using the following formula:

Voltage Drop (V) = [√3 X cable resistance (mΩ/m) X cable length (m) X current(A)] / 1000

Use cables with the largest possible cross-sectional area to ensure that voltage drop is minimized over long cable runs. Lowering the carrier frequency and installing a micro surge filter may also help to reduce voltage drop.

Installing the Inverter

Do not connect power to the inverter until installati

on has been

fully

completed and the inverter is

ready to be operated. Doing so may result in electric shock.

•

Power supply cables must be connected to the R, S, and T terminals. Connecting power cables to other terminals will damage the inverter.

•

Use insulated ring lugs when connecting cables to R/S/T and U/V/W terminals.

•

The inverter’s power terminal connections can cause harmonics that may interfere with other communication devices located near to the inverter. To reduce interference the installation of noise filters or line filters may be required.

•

To avoid circuit interruption or damaging connected equipment, do not install power factor correction capacitors, surge protection, or electronic noise filters on the output side of the inverter.

•

Use ferrite material to protect signal cables from electro-magnetic interference.

•

Take care when supporting cables using cable ties, to apply the cable ties no closer than 6 inches from the inverter. This provides sufficient access to fully close the front cover.

•

When making control terminal cable connections, use a small flat-tip screw driver (0.1in wide (2.5mm) and 0.015in thick (0.4mm) at the tip).

SA,SB, SC, they are shorted, have 24V voltage.

Do not connect power to the inverter until

installation has been fully completed and the inverter is ready to be operated. Doing so may result in electric shock.

Step 5 PNP/NPN Mode Selection

The ”S” Series inverter supports both PNP (Source) and NPN (Sink) modes for digital inputs at the terminals. Select an appropriate mode to suit requirements using the PNP/NPN selection switch (SW1) on the control board. Refer to the following information for detailed applications.

PNP Mode (Source)

Select PNP using the PNP/NPN selection switch (SW1). Note that the factory default setting is NPN mode. CM is is the common ground terminal for all analog inputs at the terminal, and P24 is 24V internal source. If you are using an external 24V source, build a circuit that connects the external source (-) and the CM terminal.

NPN Mode (Sink)

Select NPN using the PNP/NPN selection switch (SW1). Note that the factory default setting is NPN mode. CM is is the common ground terminal for all analog inputs at the terminal, and P24 is 24V internal source.

Installing the Inverter

Step 6 Disabling the EMC Filter for Power Sources with Asymmetrical Grounding

An EMC filter prevents electromagnetic interference by reducing radio emissions from the inverter. EMC filter use is not always recommended, as it increases leakage current. If an inverter uses a power source with an asymmetrical grounding connection, the EMC filter MUST be disconnected.

•

Do not use the EMC filter if the inverter uses a power source with an asymmetrical grounding structure, for example a grounded delta connection. Personal injury or death by electric shock may result.

•

Wait at least 10 minutes before opening the covers and exposing the terminal connections.

Before

starting work on the inverter, test the connections to ensure all DC voltage has been fully discharged. Personal injury or death by electric shock may result.

Before using the inverter, confirm the power supply’s grounding system. Disable the EMC filter if the power source has an asymmetrical grounding connection. Refer to the figures below to locate the EMC filter on/off terminal and replace the metal bolt with the plastic bolt. If the EMC filter is required in the future, reverse the steps and replace the plastic bolt with the metal bolt to reconnect the EMC filter.

Test Run

After the post-installation checklist has been completed, follow the instructions below to test the inverter.

1 Turn on the power supply to the inverter. Ensure that the keypad display light is on.

2 Select the command source.

3 Set a frequency reference, and then check the following:

•

If V1 is selected as the frequency reference source, does the reference change according to the input voltage at VR?

•

If V2 is selected as the frequency reference source, is the voltage/current selector switch (SW2) set to voltage, and does the reference change according to the input voltage?

•

If I2 is selected as the frequency reference source, is the voltage/current selector switch (SW2) set to current, and does the reference change according to the input current?

4 Set the acceleration and deceleration time.

5 Start the motor and check the following:

•

Ensure that the motor rotates in the correct direction (refer to the note below).

•

Ensure that the motor accelerates and decelerates according to the set times, and that the motor speed reaches the frequency reference.

ote

If the forward command (

Fx) is on, the motor should rotate counterclockwise when viewed from

the load side of the motor. If the motor rotates in the reverse direction, switch the cables at the

and V terminals.

Verifying the

Motor

Rotation

1 On the keypad, set the drv (Frequency reference source) code in the Operation group to 0

(Keypad).

2 Set a frequency reference.

3 Press the [RUN] key. Motor starts forward operation.

4 Observe the motor’s rotation from the load side and ensure that the motor rotates

counterclockwise (forward).

Installing the Inverter

If the motor r

otates

in the reverse direction, two of the U/V/W terminals need to be switched.

•

Check the parameter settings before running the inverter. Parameter settings may have to be adjusted depending on the load.

•

To avoid damaging the inverter, do not supply the inverter with an input voltage that exceeds the rated voltage for the equipment.

•

Before running the motor at maximum speed, confirm the motor’s rated capacity. The “S” Series inverters can be used to easily increase motor speed, use caution to ensure that motor speeds

not accidently exceed the motor’s rated capacity.

In.17.V1 Quantizing

Quantizing may be used when the noise level is high in the analog input (V1

terminal) signal. Quantizing is useful when you are operating a noise-sensitive system, because it suppresses any signal noise. However, quantizing will diminish system sensitivity (resultant power of the output frequency will decrease based on the analog input). You can also turn on the low-pass filter using code In.07 to reduce the noise, but increasing the value will reduce responsiveness and may cause pulsations (ripples) in the output frequency.

Code

Description

Parameter values for quantizing refer to a percentage based on the maximum input. Therefore, if the value is set to 1% of the analog maximum input (60Hz), the output frequency will increase or decrease by 0.6Hz per

0.1V difference.

When the analog input is increased, an increase to the input equal to 75% of the set value will change the output frequency, and then the frequency will increase according to the set value. Likewise, when the analog input decreases, a decrease in the input equal to 75% of the set value will make an initial change to the output frequency.

As a result, the output frequency will be different at acceleration and deceleration, mitigating the effect of analog input changes over the output frequency.

Operation

•

Full control of the inverter is available with the keypad during local operation.

•

During local operation, jog commands will only work if one of the P1–P5 multi-function terminals (codes In.65–69) is set to 13(RUN Enable) and the relevant terminal is turned on.

•

During remote operation (remote operation), the inverter will operate according to the previously set frequency reference source and the command received from the input device.

•

If Ad.10 (power-on run) is set to 0(No), the inverter will NOT operate on power-on even when the following terminals are turned on:

- Fwd/Rev run (Fx/Rx) terminal

- Fwd/Rev jog terminal (Fwd jog/Rev Jog)

- Pre-Excitation terminal To operate the inverter manually with the keypad, switch to local mode. Use caution when switching back to remote operation mode as the inverter will stop operating. If Ad.10 (power-on run) is set to 0(No), a command through the input terminals will work ONLY AFTER all the terminals listed above have been turned off and then turned on again.

•

If the inverter has been reset to clear a fault during an operation, the inverter will switch to local operation mode at power-on, and full control of the inverter will be with the keypad. The inverter will stop operating when operation mode is switched from “local” to “remote”. In this case, a run command through an input terminal will work ONLY AFTER all the input terminals have been turned off.

Inverter Operation During Local/Remote Switching

Switching operation mode from “remote” to “local” while the inverter is running will cause the inverter to stop operating. Switching operation mode from “local” to “remote” however, will cause the inverter to operate based on the command source:

•

Analog commands via terminal input: the inverter will continue to run without interruption based on the command at the terminal block. If a reverse operation (Rx) signal is ON at the terminal

block

at startup, the inverter will operate in the rev

erse direction even if it was running in the

forward direction in local operation mode before the reset.

•

Digital source commands: all command sources except terminal block command sources (which are analog sources) are digital command sources that include the keypad, LCD keypad, and communication sources. The inverter stops operation when switching to remote operation mode, and then starts operation when the next command is given.

A fault may be triggered if the inverter starts operation while a motor’s load (fan-type load) is in free-run state. To prevent this from happening, set bit4 to 1 in Cn. 71 (speed search options) of the Control group. The inverter will perform a speed search at the beginning of the operation.

•

If the speed search is not enabled, the inverter will begin its operation in a normal V/F pattern and accelerate the motor. If the inverter has been turned on without power-on run enabled, the terminal block command must first be turned off, and then turned on again to begin the inverter’s operation.

The digital input for the run command (Fx/Rx-1) must remain closed to allow the inverter to run after a successful reset. When a fault occurs, the inverter cuts off the output and the motor will freerun. Another fault may occur if the inverter begins its operation while motor load is in a free-run state.

If, for example, maximum frequency is 60.00Hz, the Acc/Dec times are set to 5 seconds, and the frequency reference for operation is set at 30Hz (half of 60Hz), the time required to reach 30Hz therefore is 2.5 seconds (half of 5 seconds).

If for example, the acceleration time is set at 6000 seconds, a time scale change from 1 second to 0.01 second will result in a modified acceleration time of 60.00 seconds.

Acc/Dec Time Based on Operation Frequency

Acc/Dec times can be set based on the time required to reach the next step frequency from the existing operation frequency. To set the Acc/Dec time values based on the existing operation frequency, set bA. 08 (acc/dec reference) in the Basic group to 1 (Delta Freq).

Description

bA.69 Xcel Change Fr

When

the

Acc/Dec switch frequency (

bA.69

, Xcel Change Fr) is

set and the

inverter

operation is at or below the set frequency, it will use the accel and decel times set in parameters bA.70 and 71. If the operation frequency is above the switch frequency, it will use the accel and decal times set in parameters ACC and dEC codes. If you configure the P1–P5 multi-function input terminals for multi-step Acc/Dec gradients (XCEL-L, XCEL-M, XCEL-H), the inverter will operate based on the Acc/Dec inputs at the terminals instead of the Acc/Dec switch frequency configurations.

Acc/Dec Pattern Configuration

Acc/Dec gradient level patterns can be configured to enhance and smooth the inverter’s acceleration and deceleration curves. The linear pattern features a linear increase or decrease to the output frequency, at a fixed rate. With an S-curve pattern, a smoother and more gradual increase or decrease of output frequency is performed. S-curve gradient level can be adjusted using codes Ad. 03–06 in the Advanced group.
