safety interlock circuit to avoid un-
wanted drive trips.
• No power factor correction capaci-
tors can be connected between
drive and motor.
• Two speed motors must be wired
permanently for full speed.
• Y-start, -run motors must be wired
permanently for run.
Installation checks
1. Input fusing in power supply for all drives
must be provided.
2. Environmental concerns - for standard
NEMA 1 drive:
• Clean air supply
• Dry air (5% to 85% relative humidity,
non-condensing)
• 32°F (0°C) to 104°F (40°C) ambient
temperature operating range, or as
rated
• 1000m (3,300 ft) maximum eleva-
tion with no derating
• Keep any construction dirt out of
drive.
3. Wiring
• Wire drive in accordance with in-
structions and diagrams received
with drive.
• Separate conduits must be provi-
ded to drive for input power, output
power, and control wiring.
• Protect signal wires from noise.
• Ground each drive individually.
• Double check input and output pow-
er wiring for correct location.
Setting up drive for motor start
Ensure that all warnings provided in this manual have
been adhered to. Apply power to the unit. Enter motor
nameplate data into drive through Quick Menu.
1. Parameter 102, MOTOR POWER (in kW)
(See conversion table in parameter 102, Mo-
tor Power, in this manual.)
2. Parameter 103, MOTOR VOLTAGE
3. Parameter 104, MOTOR FREQUENCY
4. Parameter 105, MOTOR CURRENT
5. Parameter 106, MOTOR SPEED
6. Parameter 107, select AUTOMATIC MOTOR
TUNING
Operational tests - HAND
1. Check motor rotation from drive. If incorrect,
disconnect input power from drive and re-
verse two leads between drive and motor.
2. Accelerate motor quickly to full speed and
verify operation.
3. Decelerate motor quickly to stop and verify
operation.
4. 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.
