Storage condition
A motor with PG and option card (OPC-
G11S-PG) are necessary. (ZERO)
P11S series doesn't have this function.
Option card (PG/SY) required
Option card is required.
230V : 400Vdc, 460V : 800Vdc
• Line voltage : 5kV
• Between power line and ground : 7kV (1.2/50µs)
230V : 200Vdc, 460V : 400Vdc
•
Operation details are selected by Function code F14.
• 30HP or smaller inverter
• 40HP or larger inverter
• Thermal time constant (0.5 to 75.0
minutes) can be preset for a special motor.
• External singnal is used for changeover.
Related transistor output : OL
<OL1, OL2>
• The inverter stops electricity discharge
operation, to protect the DB resistor.
Then, usually inverter displays "OU trip".
• Connects the relay output to the terminal
THR, to protect the DB resistor.
Then, usually the inverter displays "OH trip".
Number of Auto reset times and reset
interval can be preset.
Pollution degree 2 when complying with Low
Voltage Directive is needed.
*
When altitude is 6600ft (2000m) or higher,
interface circuit should be isolated from main
power lines, to comply with Low Voltage Directive.
The stopped motor holds its rotor angle. For a rotating motor, the
rotor angle is held after deceleration.
The SY option card can be used for positioning control by
differential counter method.
This function controls the synchronized operation between 2 axes with PGs.
Protects the inverter by electronic thermal and detection of inverter temperature.
Detects DC link circuit overvoltage, and stops the inverter.
Protects the inverter against surge voltage between the main
circuit power line and ground.
Detects DC link circuit undervoltage, and stops the inverter.
Phase loss protection for power line input
Protects the inverter by detection of inverter heat sink temperature.
Short-circuit protection for inverter output circuit
• Ground fault protection for inverter output circuit (3-phase current
detection method)
• Zero-phase current detection method
• The inverter trips, and then protects the motor.
• Electronic thermal overload relay can be selected for standard
motor or inverter motor
• The second motor's electronic thermal overload relay can be
preset for 2-motor changeover operation.
• Before the inverter trips, outputs OL(Overload early warning)
signal at a preset level.
• Prevents DB resistor overheating by internal electronic thermal
overload relay. (10HP or smaller for G11S, 15HP or smaller for
P11S)
•Prevents DB resistor overheating by external thermal overload
relay attached to DB resistor. (15HP or larger for G11S, 20HP or
larger for P11S)
When the inverter executes auto-tuning, detects each phase
impedance imbalance (and stops the inverter).
When the motor temperature exceeds allowable value, the inverter
trips automatically.
When the inverter is tripped, it resets automatically and restarts.
• Indoor use only.
• Free from corrosive gases, flammable gases, oil mist, dusts, and
direct sunlight.
