3.3WIRING THE MAIN CIRCUIT
S Make sure to ground the ground terminal.
(Ground resistance 200V class: 100Ω or less, 400V class: 10Ω or less)
Failure to observe this warning can result in an electric shock or a fire.
S Never connect the AC main circuit power supply to output terminals U, V and W.
The inverter will be damaged and invalidate the guarantee.
S (Standard connection)
Be sure to connect the motor leads to the correct output terminals:
Motor lead U to output terminal U,
Motor lead V to output terminal V, and
Motor lead W to output terminal W.
Failure to observe this caution may cause the motor to run unusual way such as in reverse.
S With the standard connection for the output terminals, the motor rotates counterclock-
wise as viewed from the load side in a forward operation. To rotate the motor clockwise
in a forward operation, connect the output terminals as refered in Appendix 6.
WARNING
CAUTION
(1) Wiring Precautions for Main Circuit Input
(a) Installation of Molded-case Circuit Breaker (MCCB)
Make sure to connect MCCBs or fuses between the AC main circuit power supply and
VS-686SS5 input terminals R, S and T to protect wiring.
(b) Installation of Ground Fault Interrupter
When connecting a ground fault interrupter to input terminals R, S and T, select one that
is not affected by high frequency.
Examples: NV series by Mitsubishi Electric Co., Ltd. (manufactured in or after1988),
EG, SG series by Fuji Electric Co., Ltd. (manufactured in or after 1984)
24
3WIRING
(c) Installation of Magnetic Contactor
Inverter can be used without a magnetic contactor (MC) installed at the power supply side.
When the main circuit power supply is shut OFF in the sequence, a magnetic contactor (MC)
can be used instead of a molded-case circuit breaker (MCCB). However, when a magnetic
contactor is switched OFF at the primary side, regenerative braking does not function and
the motor coasts to a stop.
S The load cannot be operated/stopped by opening/closing the magnetic contactor at the
power supply side.
S When using a brakingresistor unit, use a sequencer to break power supply side on over-
load relay trip contact. If the inverter malfunctions, the braking resistor unit may be
burned out.
(d) Terminal Block Connection Sequence
Input power supply phases can be connected to any terminal regardless of the order of R,
S and T on the terminal block.
(e) Installation of Reactor
When connecting an inverter (200V/400V 15kW or less) to a large capacity power supply
transformer (600kVA or more), or when switching a phase advancing capacitor, excessive peak current flows in the input power supply circuit, which may damage the converter
section. In such cases, install a DC reactor (optional) between inverter ¨1 and ¨2 terminals or an AC reactor (optional) on the input side. Installation of a reactor is effective for
improvement of power factor on the power supply side.
(f)Installation of Surge Suppressor
For inductive loads (magnetic contactors, magnetic relays, magnetic valves, solenoids,
magnetic brakes, etc.) connected near the inverter, use a surge suppressor simultaneously.
(g) Prohibition of Installation of Phase Advancing Capacitor
If a phase advancing capacitor or surge suppressor is connected in order to improve the
power factor, it may become overheated and damaged by inverter high harmonic components. Also, the inverter may malfunction because of overcurrent.
(h) Using Input Noise Filters
Noise filters can reduce a higher harmonics noise leaking from the drive unit to the power
line.

(2) Wiring Precautions for Main Circuit Output
(a) Connection of Terminal Block and Load
Connect output terminals U, V and W to motor lead wires U, V and W. For standard connections, be sure to connect the motor leads to the correct output terminals: motor lead U to
output terminal U, motor lead V to output terminal V, and motor lead W to output terminal
W.
With the standard connection for the output terminals, the motor rotates counterclockwise
as viewed from the load side in a forward operation. To rotate the motor clockwise in a forward operation, connect the output terminals as refered in Appendix 6.
(b) Strict Prohibition of Connection of Input Power Supply to Output Terminals
3WIRING
Never connect the input
power supply to output terminals U, V and W.
(c) Installation of Low-voltage Manual Starter
Make sure to connect a low-voltage manual starter to the inverter output side when the motor is rotated by the load even if the inverter power supply is OFF. Turn OFF the starter before performing maintenance/inspection or wiring.
Example:LB series of AICUT manufactured by Aisei
(d) Strict Prohibition of Short Circuiting or Grounding of Output Circuit
Never touch the output circuit directly or put the output line in contact with the inverter case.
Otherwise, it may cause an electric shock or grounding. In addition, never short circuit the
output line.
(e) Prohibition of Connection of Phase Advancing Capacitor or LC/RC Line Filter
Never connect a phase advancing capacitor or LC/RC line filter to the output circuit.
(f)Avoidance of Installation of Magnetic Starter
Do not connect a magnetic starter or magnetic contactor to the output circuit. If the load
is connected while the inverter is running, the inverter overcurrent protective circuit operates because of inrush current.
(g) Installation of Thermal Overload Relay
An electronic overload protective function is incorporated into the inverter. When using
a thermal overload relay, set inverter constant L1-01 to 0 (motor protection selection: disabled).
27
(h) Using Output Noise Filters

(i)Countermeasures Against Inductive Noise
As described previously,a noise filter can be used to prevent inductive noise fromgenerated
on the output side. Alternatively, cables can be routed through a grounded metal pipe to
prevent inductive noise. Keeping the metal pipe at least 30 cm away from the signal line
considerably reduces inductive noise.

(k) Wiring Distance between Inverter and Motor
If the total wiring distance between inverter and motor is excessively long and the inverter
carrier frequency (main transistor switching frequency) is high, harmonic leakage current
from the cable will adversely affect the inverter and peripheral devices.
Consider the wiring distance between inverter and motor when increasing the carrier frequency value. Carrier frequency can be set by constant C6-02.

in the event of an emergency, a power failure, or an abnormality in the inverter occuring.
Failure to observe this caution can result in personal injury.
S
If using with an elevator, take safety measures on the machine’s side to prevent the ele-
vator from dropping.
Failure to observe this caution can result in personal injury.
S
Do not change signals during operation.
The machine or the inverter may be damaged.
S
All the constants of the inverter have been preset at the factory. Do not change the
settings unnecessarily.
The inverter may be damaged. For supply voltage, follow Par. 4.2.
S
Be sure to set the motor constants in accordance with the values listed on the motor name-
plate.
Failure to observe this caution may cause the torque to be insufficient, which may result in the
following motor malfunctions:
• The motor is pulled in the direction of the load.
• The motor rotates in reverse.
• The motor does not rotate.
• The motor suddenly accelerates.

(2) OPERATION MODE SELECTION
The VS-686SS5 has two operation modes, LOCAL and REMOTE, as described below. These
two modes can be selected by the digital operator “LOCAL/REMOTE” key only while the
operation is stopped. The selected operation mode can be verified by observing the digital
operator SEQ and REF LEDs (both LEDs light in REMOTE mode).
The operation mode at power ON is set to REMOTE (run by control circuit terminals 13 and
14 speed reference and run command from a control circuit terminal) prior to shipment. Multifunction contact inputs from control circuit terminals 3 to 8 are enabled in both operation
modes LOCAL/REMOTE.
LOCAL
REMOTE
Both speed reference and run command are set by the digital operator. SEQ and REF LEDs
go OFF.
Master speed reference and run command can be selected by setting constants b1-01 and
b1-02. The factory setting is “1” (command from control circuit terminal).

APPENDIX 5ERROR PROCESSING IN PG ZERO-PULSE
ADJUSTMENT
Fault (major, minor) which could occur during normal operation is also detected during PG zero-pulse
adjustment. If a fault occurs including minor fault, the motor stops after coasting (baseblock) and PG
zero-pulse adjustment is interrupted regardless of the fault stop mode.
During PG zero-pulse adjustment, errors indicated in the table below are also detected in addition to
the faults which could occur in normal operation. The motor stops after coasting (baseblock) and PG
zero-pulse adjustment is interrupted if any of these errors is detected. The error messages are not recorded in the fault history.
When the PG zero-pulse adjustment is interrupted, the value set for T1-02 is automatically returned
to “0.” The setting for all constants (including T1-0j) is automatically returned to the setting made
before the start of PG zero-pulse adjustment and the setting of these constants cannot be changed.

APPENDIX 6ROTATION DIRECTION OF MOTOR
If the standard connection is used for the output terminals of the main circuit, the motor rotates counterclockwise as viewed from the load side of the motor in a forward operation.
To rotate the motor clockwise in a forward operation, use the following procedures to change the
connection of the terminals and the setting of the constants, check the motor speed detection, and
adjust the PG zero-pulse.
(1) Reconnect the output terminals of the main circuit:
Connect motor lead V to output terminal W.
Connect motor lead W to output terminal V.
Do not change the connection between lead U and output terminal U.

(2) Modify the setting of constant F1-05 (For flux vector control with PG)
Set F1-05 (PG rotation direction) to 0.
(3) Check the motor speed detection (For flux vector control with PG)
Refer to page 48.
(4) Adjust the PG zero-pulse (For flux vector control with PG)
Refer to page 49.
Do not change the connection of the PG cable.
•
If the rotation direction of the motor is set to clockwise for a forward operation (Refer
•
to Fig.A-2), change the connection of the output terminal of the main circuit to the
standard connection and then proceed to steps (2) through (4).
