VLT 6000 Start-Up

Pre-installation Checks

1. Compare drive model number to what was ordered.
2. Ensure each of following are rated for same voltage:
•
Drive
•
Power line
•
Motor
3. Record following motor data:
•
Voltage
•
Frequency
•
Full load current
•
Full load speed
•
Power — convert HP to kW (See conversion table in parameter
102, Motor Power, in this manual.)
4. Ensure that rated drive current is equal to or greater than total full
load current.
•
For multiple motor operations, add up full load current ratings of
all motors.
•
Drive can be at most one size smaller than motor.
•
If drive rating is less than motor, full motor output cannot be achieved.
5. Check motor wiring:
•
Any disconnect between drive and motor should be interlocked
to drive safety interlock circuit to avoid unwanted drive trips.
•
No power factor correction capacitors can be connected between
drive and motor.
•
Two speed motors must be wired permanently for full speed.
Y-start, H-run motors must be wired permanently for run.
•

Installation Checks

1. Input fusing in power supply for all drives must be provided (see
Input Fuses section in this manual).
2. Environmental concerns — for standard NEMA 1 drive:
•
Clean air supply
•
Dry air (max 95% relative humidity, non-condensing)
•
14 o F to 104 o F ambient temperature operating range, or as rated
•
3,300 foot maximum elevation with no derating
3. Mounting
•
Vertical
•
Drives with heat sink fins exposed in back of unit must be
mounted against a solid surface (see Clearances section in this
manual).
•
Keep any construction dirt out of drive.
4. Wiring
•
Wire drive in accordance with instructions and diagrams received
with drive.
•
Separate conduits must be provided to drive for input power,
output power, and control wiring.
•
Note that safety interlock and remote run/stop circuitry is 115 VAC
for drives with bypasses.
•
Use knockouts or conduit entry plates. Avoid metal shavings in cabinet.
28
•
Protect signal wires from noise.
•
Ground each drive individually.
•
Double check input and output power wiring for correct location.

Setting Up Drive for Motor Start

Enter motor nameplate data into drive through Quick Menu.
1. Parameter 101:
•
If one motor is connected to drive, set to AEO FUNCTION.
•
If more than one motor connected to drive, set to MULTIPLE
MOTORS. (Parameter 108, MULTIPLE MOTOR STARTING
VOLTAGE should be adjusted later to provide reliable starts and
minimum starting current.)
2. Parameter 102, MOTOR POWER (in kW) (See conversion table in
parameter 102, Motor Power, in this manual.)
3. Parameter 103, MOTOR VOLTAGE
4. Parameter 104, MOTOR FREQUENCY
5. Parameter 105, MOTOR CURRENT
6. Parameter 106, MOTOR SPEED
7. Parameter 107, (optional) select AUTOMATIC MOTOR ADAPTA-
TION and run AMA in accordance with procedure in parameter
107, Automatic Motor Adaptation, in this manual.
8. Press HAND START key to initiate operation in local control.
Operational Tests — HAND
1. Check motor rotation from drive. If incorrect, disconnect input
power from drive and reverse two leads between drive and motor.
2. If a bypass is provided, check motor rotation in bypass mode. If
incorrect, disconnect input power from drive and reverse two input
power leads.
3. Accelerate motor quickly to full speed and verify operation.
4. Decelerate motor quickly to stop and verify operation.
5. Operate motor over entire speed range while closely checking for
resonance.
Operational Tests — AUTO
1. Ensure that drive follows run/stop and safety interlock commands
from system.
2. Ensure drive follows speed reference, or feedback, from system.

Final Adjustments

1. Use parameters 216 through 220 to reject any resonant points.
2. Lock out keypad functions, as required.

General Troubleshooting

1. Display Messages:
•
AUTO START—Drive has tripped off and is in process of
automatically restarting.
•
TRIP—Drive has tripped off. Press RESET to start.
•
TRIP LOCKED—Drive has tripped off. Remove and apply
power before restarting with RESET.
2. Refer to Warnings and Alarms section in this manual.
3. Check tightness of all connections and wires for proper location.
4. Measure input signals.
5. Check drive input and output for balanced voltage and current.
