Selecting Cooling Fan Operation. YASKAWA V7 Drive, VS-606V7 Series

•

Selecting Cooling Fan Operation

In order to increase lifetime, the cooling fan can be set to operate only when inverter is running.

n039 = 0 (factory setting) : Operates only when inverter is running.

(Continuous operation for 1 minute after inverter is stopped.)

1 : Operates with power ON.

•

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 communication and 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.

Communications connection terminal

Use the following S+, S-, R+ and R- terminals for MEMOBUS communications.

Change the termination resistor as shown below.

At RS-422, RS-485 communications: Turn ON SW2 ON/OFF switch of only the inverter at the termination viewed from the PLC.

Notes: 1.

Separate the wiring for communication from the main circuit wiring or other power lines.

2.

Use shielded cables for communication wiring; connect the shielded sheath to the ground terminal and terminate the other end to prevent it from being connected (to prevent noise malfunction).

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.

•

Setting necessary parameters for communication

Communication related parameters must be set for PLC communication. parameters n151 to n157 cannot be set during communication. Always set them prior to performing communication.

Message format

For communications, the master (PLC) sends a command to the slave (VS-606V7) and the slave responds to it. The configuration for sending and receiving is as shown to the right. The length of the data varies according to the contents of commands (functions).

The interval between messages must be maintained at the following amount.

• 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 MSB 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.

95

• 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).

When a parameter is written from the PLC by communications, the parameter is written to the parameter data area on the RAM in the VS-606V7. ENTER command is a command to write the parameter data on the RAM to the non-volatile memory in the

VS-606V7. Writing data (can be undefined) to register number 0900H during stop executes this ENTER command.

Maximum number of writing times of the non-volatile memory used for VS-606V7 is

100,000; do not execute the ENTER command excessively. When a parameter is changed from the digital operator, the parameter data on the RAM is written to the nonvolatile memory without ENTER command.

Register number 0900H is used only for write-in. If this register is readout, register number error (error code: 02H) occurs.

Performing self-test

VS-606V7 is provided with a function to perform self-diagnosis for operation check of the serial communication I/F circuit. This function is called self-test. In the self-test, connect the sending terminal with the receiving terminal in the communication section.

It assures if the data received by VS-606V7 is not being changed. It also checks if the data can be received normally. Carry out the self-test in the following procedure.

(1) Turn ON the VS-606V7 mini power supply. Set parameter n056 to 35 (self-test).

(2) Turn OFF the VS-606V7 mini power supply.

(3) Make the following wiring with the power supply turned OFF.

(4) Turn the power ON.

Normal operation: Operator displays frequency reference value.

Faulty operation: Operator displays “ signal is turned OFF.

• Energy-saving Control Mode (n140, n158)

Calculates the voltage for the best motor efficiency when operating in energysaving control mode. The calculated voltage becomes the output voltage reference.

The factory setting is set to the max. applicable motor capacity of a Yaskawa standard motor.

The greater the energy-saving coefficient is, the greater the output voltage becomes.

When using a motor other than a Yaskawa standard motor, set the motor code corresponding to the voltage and capacity to n158. Then, change the setting of the energy-saving coefficient K2 (n140) by 5% so that the output power becomes the smallest.

When the motor code is set to n158, the energy-saving coefficient K2, which corresponds to the motor code, is set n140.

Energy-saving search operation

In the energy control mode, the max. applicable voltage is calculated using the output power. However, a temperature change or the use of another manufacturer’s motor will change the fixed parameters, and the max. applicable voltage may not be emitted. In the search operation, change the voltage slightly so that the max. applicable voltage can be obtained.

Condition

Determined by the frequency reference selection (n004)

When the local mode is selected, the target value is determined by frequency reference selection in local mode

(n008).

When the multi-step speed reference is selected, the currently selected frequency reference becomes the target value.

Notes: 1. When selecting frequency reference from the control circuit terminal FR as the target or feedback value, the V-I switch of SW2 on the control circuit board must be selected depending on the input method (current or voltage input).

2. Never use the frequency reference from the control circuit terminal FR for both the target and feedback values. The frequency reference for both the target value and the feedback value becomes the same.

(Example)

When the frequency reference from the control circuit terminal FR, with a voltage of 0 to 10 V, is selected as the target value and n004=2, and when at the same time the frequency reference from the control circuit terminal FR, with a current of 4 to 20 mA, is selected as the feedback value and n164=1, the feedback value will be set as the frequency reference from the control circuit terminal FR.

3. When using the analog signal (0 to 10V / 4 to 20mA) which inputs to the CN2 terminal of the digital operator JVOP-140 as the target or feedback value of

PID control, never use it as a multi-analog input. Parameter n077 (multifunction analog input) should be set to 0 (disabled).

Setting

Range

0 to 100

Initial

Setting

100

This parameter prevents the calculated value of the integral control from exceeding the fixed amount. There is normally no need to change the setting.

Reduce the setting if there is a risk of load damage, or of the motor going out of step by the inverter’s response when the load suddenly changes. If the setting is reduced too much, the target value and the feedback value will not match.

Set this parameter as a percentage of the maximum output frequency with the maximum frequency as 100%.

Parameter n135 is the low-pass filter setting for PID control outputs.

There is normally no need to change the setting.

If the viscous friction of the mechanical system is high or if the rigidity is low causing the mechanical system to resonate, increase the setting so that it is higher than the resonance frequency period.
