Page 3 NOTATION FOR SAFETY PRECAUTIONS Read this instruction manual thoroughly before installation, operation, mainte- nance, or inspection of the Varispeed V7. In this manual, safety precautions are classified as either warnings or cautions and are indicated as shown below. WARNING Indicates a potentially hazardous situation which, if not avoided, may result in death or serious injury.
Page 4 PRECAUTIONS FOR UL/cUL MARKING • Do not connect or disconnect wiring, or perform signal checks while the power supply is turned ON. • The Inverter internal capacitor is still charged even after the power supply is turned OFF. To prevent electric shock, disconnect all power before ser- vicing the Inverter, and then wait at least one minute after the power sup- ply is disconnected.
Page 5 (open chassis type), or below 40°C (105°F) for NEMA 1 (TYPE 1), IP20 (top closed type). Overheating may cause a fire or damage the Inverter. • The Varispeed V7 generates heat. For effective cooling, mount it vertically. Refer to the figure in Mounting Dimensions on...

WIRING WARNING (Ref. page) • Only begin wiring after verifying that the power supply is turned OFF. Failure to observe this warning may result in an elec- tric shock or a fire. • Wiring should be performed only by qualified personnel.
Page 7: (Ref. Page)
CAUTION (Ref. page) • Verify that the Inverter rated voltage coincides with the AC power supply voltage. Failure to observe this caution may result in personal injury or a fire. • Do not perform a withstand voltage test on the Inverter.
Page 8: Failure To Observe This Warning May Result In An Elec
OPERATION WARNING (Ref. page) • Only turn ON the input power supply after con- firming that the Digital Operator or blank cover (optional) are in place. Do not remove the Digital Operator, remove the covers, or set rotary switches while current is flowing. Failure to observe this warning may result in an elec- tric shock.
Page 9: The Wiring For The Control Circuit Unless The Multi
WARNING (Ref. page) • If an alarm is reset with the operation signal ON, the Inverter will restart automatically. Reset an alarm only after verifying that the operation sig- nal is OFF. Failure to observe this warning may result in injury. •...
Page 10 If the indicators are not OFF, the capacitors are still charged and can be dangerous. • Do not perform withstand voltage test on any part of the Varispeed V7. The Inverter is an electronic device that uses semi- conductors, and is thus vulnerable to high voltage.
Page 11 CAUTION (Ref. page) • The control PCB employs CMOS ICs. Do not touch the CMOS elements. They are easily damaged by static electricity. • Do not connect or disconnect wires, connectors, or the cooling fan while power is applied to the circuit.

Page 29 4. Wiring • Only begin wiring after verifying that the power sup- WARNING ply is turned OFF. Failure to observe this warning may result in an electric shock or a fire. • Wiring should be performed only by qualified per- sonnel.
Page 30 4. Wiring emergency stop by using the external terminals. Delayed response may cause injury or damage the machine. Wiring Instructions 1. Always connect the power supply for the main circuit inputs to the power input terminals R/L1, S/L2, and T/L3 (R/L1, S/L2 for single- phase power) via a molded-case circuit breaker (MCCB) or a fuse.
Page 31 5. Voltage drop should be considered when determining the wire size. Voltage drop can be calculated using the following equation: Phase-to-phase voltage drop (V) × wire resistance (Ω/km) × wiring distance (m) × current (A) × 10 Select a wire size so that voltage drop will be less than 2% of the normal rated voltage.

Page 95 Explicit Message Communications The DeviceNet-compatible Inverters can transfer explicit messages (defined in DeviceNet specifications) to and from a DeviceNet master.

Page 201 Undertorque Detection An alarm signal can be output to a multi-function output terminal (P1 or P2) when the load on the machine side suddenly becomes lighter (i.e., when an undertorque occurs). To output an undertorque detection signal, set the output terminal funci- ton selection in n057, n058, or n059 to 8 (undertorque detected, NO contact) or 9 (undertorque detected, NC contact).
Page 202 7. Programming Features Undertorque Detection Level (n118) Sets the undertorque detection current level in units of 1 %. (Inverter rated current=100 %) When detected by torque is selected, motor rated torque becomes 100 %. Factory setting=10 % Undertorque Detection Time (n119) If the time for which the motor current is less than the undertorque detection level (n118) is longer than the undertorque detection time (n119), the undertorque detection function operates.
Page 203 If the indicators are not OFF, the capacitors are still charged and can be dangerous. • Do not perform withstand voltage test on any part of the Varispeed V7. The Inverter is an electronic device that uses semi- conductors, and is thus vulnerable to high voltage.
