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 braker (MCCB) or a fuse. Never connect them to terminals U/T1,V/T2,W/T3, –, +1 or +2.

Refer to page 111 for recommended peripheral devices. For singlephase inverters, always use terminals R/L1 and S/L2. Never connect to terminal T/L3.

Inverter Power Supply Connection Terminals

(2) Connect the motor wiring to terminals U/T1, V/T2 and W/T3 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 57.

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

the power wiring. Use twisted-pair shielded wire when inputting the

frequency 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 con-

form to CE requirements. (8) Only basic insulation to meet the requirements of protection class 1 and

overvoltage category II is provided with control circuit terminals.

Additional insulation may be necessary in the end product to conform to

CE requirements. (9) A closed-loop connector should be used when wiring to the main circuit

terminal. (10) 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) × wiring distance (m) × current (A) × 10

-3

Select a wire size so that voltage drop will be less than 2% of the normal

rated voltage.

 Wiring the Main Circuit

[Example of 3-phase,

200V class, 1.5kW

inverters]

GOOD GOOD POOR

• Main circuit input power supply

Always connect the power supply

line to

input terminals R/L1, S/L2,

and T/L3

[

R/L1, S/L2

for single-phase inverters]. Never connect them to terminal U/T1,V/T2,W/T3, –, +1, or +2.

Otherwise the inverter may be damaged.

For single-phase inverters, always use terminals R/L1 and S/L2. Never connect to terminal T/L3.

•

Grounding (Use ground terminal .)

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

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

NOTE

• Inverter output

Connect the motor terminals to U/T1, V/T2, W/T3.

Wiring the main circuit terminals

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

Connect with a Phillips (plus) screwdriver.

 Wiring the Control Circuit

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 5.5mm (0.22in.).

* SW7 can be changed according to sequence input signal (S1 to

S5) polarity. 0V common: NPN side (factory setting) +24 common: PNP side Refer to page 106 for SW7. Refer to page 67 for SW8.

 Wiring Inspection

After completing wiring, check the following :

▫ Wiring is proper.

▫ Wire clippings or screws are not left in the unit.

▫ Screws are securely tightened.

▫ Bare wire in the terminal does not contact other terminals.

If the FWD (REV) run command is given during the operation reference selection (n02=1) from the control circuit terminal, the motor will start automatically after the main circuit input power supply is turned ON.

NOTE

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

5. OPERATING THE INVERTER

 Test Run

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

1 Run command from the digital operator (potentiometer/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 mini using the digital operator (with potentiometer). For instructions on operation, refer to page 35.

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

If the potentiometer is switched rapidly, the motor also accelerates or decelerate rapidly corresponding to the potentiometer movement. Pay attention to load status and switch the potentiometer with the speed not to affect motor movement.

Operation Check Points

▫ Motor rotates smoothly. ▫ Motor rotates in the correct direction. ▫ Motor does not have abnormal vibration or noise. ▫ Acceleration or deceleration is smooth. ▫ Current matching the load flows. ▫ Status indicator LEDs and digital operator display are correct.

 Operating the Digital Operator

All functions of the VS mini are set by the digital operator. Below are descriptions of the display and keypad sections.

Description of Status Indicator LEDs

There are two LEDs on the middle right section of the face of the VS mini. The inverter status is indicated by various combinations of ON, BLINKING and OFF LEDs. RUN indicator and status indicator on the button have the same function.

For details on how the status indicator LEDs function at inverter faults, refer to Section 8 “FAULT DIAGNOSIS AND CORRECTIVE ACTIONS” on page 87. If a fault occurs, the ALARM LED lights.

The fault can be reset by turning ON the fault reset signal (or pressing

key on the digital operator) with the operation signal OFF or

by turning OFF the power supply. If the operation signal is ON, the

fault cannot be reset by the fault reset signal.
