optimum motor control under any operating conditions.
1. Dynamic torque-vector control
Dynamic torque-vector control system
performs high-speed calculation to determine the required motor power for the load
status. Our key technology is optimal
control of voltage and current vectors for
maximum output torque.
● A high starting torque of 200% at 0.5Hz.*
* 180% for 40HP or larger models.
● Achieves smooth acceleration/
deceleration in the shortest time for the
load condition.
● Using a high-speed CPU quickly
responds to an abrupt load change,
detects the regenerated power to control
the deceleration time. This automatic
decerelation function greatly reduces the
inverter tripping.
● Feedback control with PG
Enables the inverter to execute “vector
control with PG” by adding an optional PG
feedback card to obtain higher performance.
• Speed control range: 1:1200
• Speed control accuracy :
• Speed control response : 40Hz

● On-line tuning to continuously check for
variation of motor characteristics during
running for high-precision speed control.

second motor, which allows high-precision
driving of the second motor by changeover
operation between two motors.

to the rated torque of the motor
characteristics when combining FRENIC5000G11S
(up to 30HP at dynamic torque-vector control) with
Fuji standard three-phase motor (8-type series, 4
poles). Continuous operation torque is for limits of
allowable load torque for using the motor within the
allowable temperature range and is not for motor
output torque.
The motor output torque is shown by the short-time
operation torque.

When the DC link circuit voltage is higher than 50V, the charge lamp is ON.
Protects the inverter by electronic thermal overload function and by detection of inverter temperature.
Detects DC link circuit overvoltage,and stops the inverter. (460V : 800V DC, 230V : 400V DC)
Detects DC link circuit undervoltage,and stops the inverter. (460V : 400V DC, 230V : 200V DC)
Phase loss protection for power line input.
Protects the inverter by detection of inverter 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 (40HP or larger)
• The inverter trips,and then protects the motor. • Electronic thermal overload protection can be set for standard motor or inverter motor
• Thermal time constant (0.5 to 75.0 minutes) can be preset for a special motor.
• The second motor's electronic thermal overload protection can be preset for 2-motor changeover operation.
• Prevents DB resistor overheating by internal electronic thermal overload relay (10HP or smaller).
• Prevents DB resistor overheating by external thermal overload relay attached to DB resistor (15HP or larger).
(The inverter stops electricity discharge operation to protect the DB resistor.)
• Controls the output frequency to prevent (overcurrent) trip when the output current exceeds the limit value during acceleration.
• Lowers the output frequency to hold almost constant torque when the output current exceeds the limit value during operation at constant speed.
• Controls the output frequency to prevent (overvoltage) trip when the DC link circuit voltage exceeds the limit value during deceleration.
When the inverter executes auto-tuning, detects each phase impedance imbalance.
When the inverter is tripped, it resets automatically and restarts.
