 Modes

This section describes the VS-656DC5 monitor modes, switching between modes, and

accessing/setting user constants.

VS-656DC5 Modes

The VS-656DC5 user constants and monitoring functions have been organized in groups

called modes that make it easier to read and set user constants.

The VS-656DC5 is equipped with 4 modes, as shown in Ta b le 9.

Table 9 Modes

Mode Primary function(s)

Operation mode The VS-656DC5 can be run in this mode.

Use this mode when monitoring values such as DC voltage feedback or
power supply frequency, displaying fault information, or displaying the
fault history.

Initialize mode Use this mode when selecting the language displayed on the Digital Opera-

tor, selecting the access level for reading/setting user constants, or initializ­ing the user constants.
The language to be displayed on the Digital Operator is set to English (A1­00 = 0) prior to shipment.

Programming mode Use this mode when reading/setting the user constants required for opera-

tion.
The program-mode functions are subdivided into the following groups:

• Application: Operation mode selection

• Tuning: Acceleration time, AVR, etc.

• Option: Settings for Optional Cards

• Terminal: Settings for sequential I/O and analog I/O

• Protection: Settings for the motor and VS-656DC5 protection functions

5.4 PERIODIC MAINTENANCE OF PARTS

The VS-656DC5 is configured of many parts, and these parts must be operating properly in

order to make full use of the VS-656DC5 functions.

Among the electronic components, there are some that require maintenance depending on

their usage conditions. In order to keep the VS-656DC5 operating normally over a long

period of time, it is necessary to perform periodic inspections and replace parts according to

their service life.

When replacing parts, be careful not to drop any, such as screws, inside the VS-656DC5.

Failure to observe this caution may result in a short-circuit and a fire.

Periodic inspection standards vary depending the installation environment and usage condi-

tions of the VS-656DC5. The VS-656DC5’s maintenance periods are noted below. Keep

them as reference.

6.4 Informing the VS-656DC5 of a Peripheral Device Fault to Stop the VS-656DC5 (External Fault Function)

The external fault function operates the fault contact output to stop the VS-656DC5 opera-

tion when a malfunction or fault occurs in any of the VS-656DC5 peripheral devices. At

this time, the Digital Operator displays Efx [External Fault (Input Terminal x)]. “x” of Efx

indicates the terminal number to which the external fault signal is input. For example, when

an external fault signal is input to terminal 3, the Digital Operator displays EF3.

To use the external fault function, set H1-01 to H1-05 (Multi-function Contact Input Termi-

nals 3 to 7) to 24 to 2F.

Select the values to be set to H1-01 to H1-05 according to the combination of the following

three conditions:

• The level of a signal input from the peripheral device

• The external fault detection method

• The operation at external fault detection

Appendix B PRECAUTIONS ON VS-656DC5 APPLICATION

The total load capacity must be less than the VS-656DC5 rated output capacity according to

the motoring side capacity and the regenerating side capacity that are driven at the same

time.

Max.voltage - Min.voltage
3-phase average voltage

 Input AC Reactor

Input AC reactors each of which corresponds to each capacity of the VS-656DC5, (consider-

ing saturation current and thermal items) are necessary for the PWM converter VS-656DC5.

Use the proper reactors for applications.

 VS-656DC5 Power OFF and Harmonics Filter

Set up sequence that opens after the VS-656DC5 operation is stopped at the VS-656DC5

power suply side. Be sure to attach the specified harmonics filter to reduce the influence on

other devices caused by surge voltage at open that unexpectedly occurs during run.

 Installation on the VS-656DC5 Output (DC) Side

If installing a circuit breaker or a magnetic contactor on the VS-656DC5 output (DC) side to

shut down the power supply in an emergency, observe the following precautions.

• Be sure to confirm that the charge lamps on the VS-656DC5 and the Inverter are not lit,

and then turn on the circuit breaker or contactor.

If the circuit breaker or contactor is turned on while power is supplied to the VS-

656DC5 and the Inverter, an overcurrent may occur and damage the circuit breaker or

contactor.

• Be sure to confirm that the circuit breaker or contactor is turned on before the power is

turned on for the VS-656DC5.

E-58

Appendix B PRECAUTIONS ON VS-656DC5 APPLICATION

 Power Supply Capacity Selection

Use a power supply with a capacity larger than the VS-656DC5 rated input capacity. If a

power supply with a capacity smaller than the VS-656DC5 rated input capacity is used, an

operation error may occur. When selecting a power supply, contact your Yaskawa represen-

tative.

Use the following formula to obtain the VS-656DC5 rated input capacity.

S

conv 3 × IAC_rate × Vin ÷

[I

: VS-656DC5 rated input current (A), V

1000

: Power supply line voltage (V)]

in

 Interlocking with Inverters

It is necessary to interlock between the VS-656DC5 and the Inverter to stop the Inverter by

using the VS-656DC5 fault signal. To restart the operation after a memontary power loss at

the Inverter side, the timing for reactivation must be assured.

The “MC Operating (MCON)” signal that the VS-656DC5 outputs from the control terminal

is used to assure the timing. When the “MC Operating (MCON)” signal is “open,” use the

Inverter external baseblock input to make a sequence to shut OFF the Inverter output.

[Typical Interlock]

• When reactivation after momentary power loss is not performed (Coasting to a stop by

momentary power loss detection)

Insert the VS-656DC5 “MC Operating (MCON)” output to the Inverter “External Fault”

input.

The Inverter “External Fault” input is NC contact input. To prevent external fault oper-

ation at power supply ON, select “External fault accepted only during RUN.”

• When reactivation after momentary power loss is performed as system

Insert the VS-656DC5 “MC Operating (MCON)” output to the Inverter “External BB”

input.

Select reactivation after momentary power loss at the Inverter side. Then select the

coasting lead-in mode or speed search mode.

Select NC contact input for the Inverter “External BB” input.

 Precautions on Application of Peripheral Devices

When a noise filter is attached on the VS-656DC5 power supply side, use a noise filter of the

reactor type (without a capacitor) such as finemet zero-phase reactor, and attach it behind the

MCCB at the power supply side. Do not use a capacitor-built-in type noise filter since the

harmonic components may overheat or damage the capacitor.

E-59

 When the Power Supply is a Generator

• Use the VS-656DC5 that is exclusively for generators. (For further information, contact

your YASKAWA representative.)

• Select the generator capacity approx. twice as large as the VS-656DC5 input power sup-

ply capacity. (For further information, contact your YASKAWA representative.)

• Set such deceleration time or load so that the regenerative power from the motor will be

10% or less of the generator capacity.

 When A Phase Advance Capacitor or Thyristor Controller Is Provided

for the Power Supply

No phase advance capacitor is needed for the VS-656DC5. Installing one on the VS-

656DC5 will result in reduction of power factor.

For the phase advance capacitor that has already been installed on the same power supply

system as the VS-656DC5, attach a series reactor to prevent oscillation with the VS-

656DC5.

Contact your YASKAWA representative, if any derive generaing voltage surge or voltage

distortion such as DC motor drive thyristor controller or magnetic agitator is installed on the

same power supply system.

 Prevention from EMC (Radio Noise) or Harmonics Leak Current

No preventive action from harmonics current is needed. However, some preventive actions

from EMC (radio noise) or harmonics leak current are necessary as well as the general

inverter drives.

If any device that is apt to be affected by noise is near the VS-656DC5, use a noise filter of

the above-mentioned reactor type (zero-phase reactor).

Use a leakage relay or an earth leakage breaker designed for Inverters (products provided

with prevention from harmonics leak current), when necessary.

 Guideline for Harmonics Reduction

The guideline for harmonics is available for users who receive 6.6 kV or more from the

power supply system.

 Influence by Power Supply Distortion

When the power supply voltage is distorted, or when several devices are connected in paral-

lel to the same power supply, the harmonics contents become larger since the harmonics of

the power supply system enter the VS-656DC5.
