4. WIRING

• Wiring Instructions

(1) Always connect the power input terminals R/L1, S/L2, and T/L3 (R/L1, S/L2 for

single-phase) and power supply via a molded-case circuit breaker (MCCB). Never connect them to U/T1, V/T2, W/T3.

The single-phase (200V class) inverter can be connected to a 200V 3-phase input. However, when terminal T/L3 is connected to single-phase, never use the terminal for other purposes.

Connect to R/L1, S/L2, T/L3 Connect to R/L1, S/L2 Connect to R/L1, S/L2, T/L3

(2) Connect the motor wiring to terminals U, V, and W on the main circuit output side

(bottom of the inverter).

(3) If the wiring distance between inverter and motor is long, reduce the inverter

carrier frequency. For details, refer to “Reducing motor noise or leakage current (n46)” on page 68.

(4) Control wiring must be less than 164ft(50m) in length and separate from the power

wiring. Use twisted-pair shielded wire when inputting the freque ncy signal

externally. (5) Tighten the screws on the main circuit and control circuit terminals. (6) Do not connect or disconnect wiring, or perform signal check while the power

supply is turned ON. (7) For 400V class inverters, make sure to ground the supply neutral to conform to CE

requirements. (8) A closed-loop connector should be used when wiring to the main circuit terminal. (9) Voltage drop should be considered when determining wire size.

Voltage drop can be calculated using the following equation:

Phase- to phase voltage drop (V) = √3 wire resistance (Ω/km) x wiring distance

(m) x current (A) x 10 Select a wire size so that voltage drop will be less than 2% of the normal rated

voltage.

• Wiring the Main Circuit

L1 L2 L3

• Main circuit input power supply

Connect the power supply wiring to input terminals L1 (R), N/L2(S) and L3(T) [L1(R), N/L2(S) for single-phase specifications]. Never connect them to U/ T1, V/T2, W/T3, B1, B2, -, +1, or +2. Otherwise the inverter may be damaged. Single-phase voltage may be connected to inverter but do not use terminal T/L3 for any other purposes.

Single-phase (200V class, 0.75kW

NOTE

or less) voltage may be connected to terminal T/L3. Never use the terminal with other purposes.

• Grounding (Use ground terminal .)

Make sure to ground the ground terminal according to the local grounding code. Never ground the VS-606V7 in common with welding machines, motors, or other electrical equipment.

When several VS-606V7 units are used side by side, ground each unit as shown in examples. Do not loop the ground wires.

[Example of 3-phase 400V class, 0.37 inverters]

• Braking resistor connection (optional).

To connect the braking resistor, cut the protector on terminals B1 and B2.

To protect the braking resistor from overheating, install a thermal overload relay between the braking resistor and the inverter. This provides a sequence which shuts off the power supply, by a thermal relay trip contact.

Use this same procedure when connecting a braking resistor unit. Refer to page 104.

• Inverter output

Connect the motor terminals to U, V, W.

Wiring the main circuit termina ls

Pass the cables through wiring hole and connect. Be sure to mount the cover in its original position.

• Wiring the Control Circuit

Only basic insulation is provided for the control circuit terminal s. Additional insulation may be necessary in the end product.

• Control Circuit terminals

Pass the cable through wiring hole and connect. Be sure to mount all the covers on the original position.

* SW1 can be changed according to sequence input

signal (S1 to S7) polarity. 0V common: NPN side (factory setting) 24 common: PNP side Refer to pages 67 and 76 for SW2

Wiring the control circuit terminals

Screwdriver blade width

Insert the wire into the lower part of the terminal block and connect it tightly with a screwdriver.

Wire sheath strip length must be 0.22 in. (5.5mm).

Open the front cover and verify that the strip length is 0.22 in. (5.5mm)

• Wiring Inspection

After completing wiring, check the following:

• Wiring is properly connected.

• Wire clippings or screws are not left inside the unit.

• Screws are securely tightened.

• Bare wires in the terminal do not come in contact with other terminals. If the FWD (REV) run command is given during the operation reference selec-

Test Run

The inverter operates by setting the frequency (speed). There are three types of operation modes for the VS-606V7:

1. Run command from the digital operator (local pote ntiometer/digital setting).

2. Run command from the control circuit terminal.

3. Run command from communications (MEMOBUS communications). Prior to shipping, the drive is set up to receive run command and frequency reference

from the operator. Below are instructions for running the VS-606V7 using the digital operator JVOP-140 (with local potentiometer) or optional JVOP-147 (without local potentiometer. For instructions on operation, refer to page 37.

Operation reference or frequency reference parameters can be selected separately as shown below.

• Typical setting of V/f pattern Set the V/f pattern according to the application as described below . For 400V class, the voltage values (n012, n015, and n017) should be doubled. When running at a frequency exceeding 50Hz/60Hz, change the maximum output frequency (n011).

Note: Be sure to set the maximum output frequency according to the motor char-

acteristics

(Factory setting)

Increasing voltage of V/f pattern increases motor torque, but excessive increase may cause motor over excitation, motor overheat, or vibration.

Note: n012 is to be set to motor rated voltage.

•

Full-range automatic torque boost (when V/f mode is selected. n002=0)

Motor torque requirement changes according to load conditions. Full range automatic torque boost adjusts voltage of V/f pattern according to the requirement. The VS-606V7 automatically adjusts the voltage during parameter-speed operation as well as during acceleration. The required torque is calculated by the inverter. This ensures tripless operation and energy-saving effects.

Output voltage Torque compensation gain (n103) Required torque

∝

• Operation

Normally, no adjustment is necessary for torque compensation gain (n103 factory setting: 1.0). An excessively high setting of torque compensation gain will res ult in motor over excitation, and possible inverter faults. If adjustments are necessary , adjust n103 in increments/decrements of 0.1 for optimization. When wiring distance between the inverter and the motor are long it may be necessary to increas e t he setting of n103. When motor generates vibration, decrease the setting of n103.

Adjustment of torque compensation time parameter (n104) and torque iron loss compensation parameter (n105) are normally not required.

Adjust torque compensation parameter under the following conditions:

• Increase setting when the motor generates vibration.

• Reduce setting when motor response is low.

•

Using Vector Control Mode

Setting the control mode selection (n002) can use a vector control mode.

n002=0: V/f control mode (factory setting)

1: Vector control mode

Precaution for voltage vector control application

•

Since vector control needs motor parameters, the YASKAWA standard motor parameters have been set at the factory prior to shipment. Therefore, when an inverter exclusive-use motor is used or when a motor of any other manufacturer is driven, the required torque characteristics or speed control characteristics may not be maintained because the parameters are not matched. Set the following parameters so that they can match the motor parameters.

Adjusting speed setting signal

•

To provide frequency reference by analog input of control circuit terminal FR and FC, the relationship between analog input and frequency reference can be set.

FREQUENCY REFERENCE

(a) Analog frequency reference gain (n060)

The frequency reference provided when analog input is 10V(20mA) can be set in units of 1%. (maximum output frequency n011=100%)

∗ Factory setting : 100%

(b) Analog frequency reference bias (n061)

The frequency reference provided when analog input is 0V (4mA or 0mA) can be set in units of 1%. (Maximum output frequency n011=100%)

∗ Factory setting : 0%

Typical setting

•To operate the inverter with frequency reference of 0% to 100% at 0 to 5V input

•To operate the inverter with frequency reference of 50% to 100% at 0 to 10V input

Adjusting frequency upper and lower limits

• Frequency reference upper limit (n033) Sets the upper limit of the frequency reference in units of 1%. (n011: Maximum output frequency = 100%) Factory setting: 100%

• Frequency reference lower limit (n034) Sets the lower limit of the frequency reference in units of 1%. (n011: Maximum output frequency = 100%) When operating at frequency reference 0, operation is continued at the frequency reference lower limit. However, when frequency reference lower limit is set to less than the minimum output frequency (n016), operation is not performed. Factory setting: 0%

Using two accel/decel times

*When “deceleration to a stop” is selected (n005=0).

Torque detection

If an excessive load is applied to the machine, the resultant output current increase can be compared to the threshold setting of parameter n098, then output alarm signals to multi-function output terminals MA, MB, P1 and P2.

To output an overtorque detection signal, set output terminal function selection n057 to n059 to “overtorque detection” [Setting:6 (NO contact) or 7 (NC contact)].

∗

Overtorque detection release width (hysterisis) is set at approx. 5% of inverter rated current.

• Overtorque detection level (n098) Sets the overtorque detection current level in units of 1%. (Inverter rated current = 100%) When detection by torque is selected, motor rated torque becomes 100%. Factory setting: 160%

• Overtorque detection time (n099) If the time when the motor current exceeds the overtorque detection current level (n098) is longer than overtorque detection time (n099), the overtorque detection function operates. Factory setting: 0.1sec.

• Overtorque detection function selection 2 (n097) When vector control mode is selected, overtorque detection can be performed either by output current or by output torque. When V/f control mode is selected, n097 setting becomes invalid, and overtorque is detected by output current.

Setting Description

Jump frequencies (n083 to n086)

This function allows the prohibition or “jumping” of critical frequencies so that the motor can operate without resonance caused by machine systems. This function is also used for dead band control. Setting the value to 0.00Hz disables this function.

Set prohibited frequency 1, 2 or 3 as follows:

n083 > n084 > n085 If this condition is not satisfied the

inverter displays for one second and restores the data to original settings.

Operation is prohibited within jump frequency range. However, motor operates smoothly (without jumping) during accel/decel.

Continuing operation by automatic fault reset (n082)

Operator stop key selection (n007)

Selects processing when STOP key is pressed during operation either from multi-function input terminal or communications.

Setting Description

STOP key effective when running either from multi-function input terminals or communications. When STOP key is pressed, the inverter stops according to the setting of the parameter n005.

At this time, the digital operator displays “ “ alarm (blinking). This stop command is held in the inverter until both forward and reverse run commands are open, or until run command from communications becomes zero.

STOP key is ineffective when running either from multi-function input terminals or

communications.

Selecting stopping method (n005)

Selects the stopping method suitable for application.

Setting Description

0 Decel eration to sto p 1 Coast to stop

• Deceleration to stop Example: when accel/decel time 1 is selected

* When frequency reference is changed during running.

Upon termination of the FWD (REV) run command, the motor decelerates at the decel rate determined by the time set to decel time 1 (n020) and DC injection braking is applied immediately before stop. DC injection braking is als o applie d when the motor decelerates by setting frequency reference lower than minimum output frequency (n016) with FWD (REV) run command ON.

If the decel time is short or the load inertia is large, over voltage (OV) fault may occur at deceleration. In this case, increase the decel time or install a optional braking resistor.

Braking Torque: Without braking resistor: Approx. 20% torque of motor rating

With braking resistor: Approx. 150% torque of motor rating

• Coast to stop Example: when accel/decel time 1 is selected

* When frequency reference is changed during running.

Upon removal of the FWD (REV) run command, the motor starts coasting.

Applying DC injection braking

• DC injection braking current (n089) Sets DC injection braking current in units of 1%. (Inverter rated current=100%)

• DC injection braking time at stop (n090) Sets the DC injection braking time at stopping in units of 0.1 second. When the setting of n090 is 0, DC injection braking is not performed but inverter output is shut OFF at the timing of DC injection braking start.

When coasting to a stop is specified in stopping method selection (n005), DC injection braking at stop does not operate.

Preventing Motor from Stalling (Current Limit)

Automatically adjusts the output frequency and output current according to the load to continue operation without stalling the motor.

• Stall prevention (current limit) level during acceleration (n093) Sets the stall prevention (current limit) level during acceleration in units of 1% (Inverter rated current = 100%).

Factory setting: 170% A setting of 200% disables the stall prevention (current limit) during acceleration.

During acceleration, if the output current exceeds the value set for n093, acceleration stops and frequency is maintained. When the output current goes down to the value set for n093, acceleration starts.

* Stops the acceleration to prevent the motor

from stalling.

† Release width (hysteresis) of stall prevention

during accel is approx. 5% of inverter rated current.

In the constant horsepower area [output frequency > max. voltage output frequency (n013)], the following equation automatically decreases the stall prevention (current limit) level during acceleration, but the stall prevention level will never go below 40% of n093.

• Stall prevention (current limit) level during running (n094) Sets the stall prevention (current limit) level during running in units of 1% (Inverter current = 100%).

• Factory setting: 160%

A setting of 200% disables the stall prevention (current limit) during running. If the inverter is at speed agree and output current exceeds the value set for n094 for

longer than 100msec, deceleration starts. Deceleration continues until the output current falls below the value set for n094.

When this occurs, the inverter will accelerate back up to the set frequency. Stall prevention accel/decel settings during operation are set either by accel time 1

(n019) and decel time 1 (n020), or accel time 2 (n021) and decel time 2 (n022).

* Decreases frequency to prevent the motor

from stalling.

† At acceleration start, output hysteresis is

approx. 5% of inverter rated current.

Decreasing Motor Speed Fluctuation

Slip compensation (When V/f control mode n002=0)

As the load becomes larger, motor speed is reduced and motor slip value is increased. The slip compensating function controls the motor spe ed at a parame te r value even if the load varies.

When inverter output current is equal to the motor rated current (n036), the compensation frequency is added to the output frequency.

The electronic thermal overload function monitors motor temperature, based on inverter output current and time, to protect the motor from overheating. When electronic thermal overload relay is enabled, an “ ” error occurs, shutting OFF the inverter output and preventing excessive overheating in the motor. When operating with one inverter connected to one motor, an external thermal relay is not needed. When operating several motors with one inverter, install a thermal relay on each motor.

Using MEMOBUS (MODBUS) Communications

Serial transmission is available with VS-606V7 using programmable controller (MEMOCON series) and MEMOBUS.

MEMOBUS (MODBUS) communications

•

MEMOBUS system is composed of a single master (PLC) and slaves (1 to 31 VS-606V7 units). Communication between master and slave (serial communication) is controlled according to the master program with the master initiating communica tion a nd the slave responding. The master sends a signal to one slave at a time. Each slave has a pre-registered address No., and the master specifies the number and conducts signal communication. The slave receives the communications to carry out designated functions and reply to the master.

3. When communication is performed through RS-485, connect S+ and R+, S- and R- terminals outside the inverter as shown right side.

Procedure for communications with PLC

The following shows the procedure for communications with PLC. (1) Connect the communication cable between the PLC and the VS-606V7 with the

power supply turned OFF. (2) Turn the power ON. (3) Set the parameters (n151 to n157) required for communication by using the digital

operator. (4) Turn the power OFF once to verify that the digital operator displays have been

completely erased. (5) Turn the power ON again. (6) Communications with the PLC starts.

• Data: Composes a series of data by combining holding register numbers (test codes for loop-back numbers) and their data. Data length depends on the contents of the commands.

• Error check: CRC-16 (Calculate the value by the following method.)

1. The default value at calculation of CRC-16 is normally 0. In the MEMOBUS system, change the default to 1 (all 1 to 16-bit).

2. Calculate CRC-16 assuming that the loop address LSB is MS B and the last data MSB is LSB.

3. Also calculate CRC-16 for a response message from the slave and refer it to CRC-16 in the response message.

• Read out holding register contents [03H]

Reads out the contents of the holding registers with the continuous numbers for the specified quantity. The contents of holding register is divided into the upper 8 bits and the lower 8 bits. They become the data items in response message in the order of numbers. Example: Reads out status signal, fault contents, data link status and frequency reference from the VS-606V7 (slave 2).
