Features

You can compensate for a voltage drop in the low-frequency region to improve motor torque reduction in the low-speed region.

￿Motor torque in the low-frequency range can be adjusted to the load to increase the starting motor torque.

￿The starting torque boost can be changed by switching terminal RT.

￿When simple magnetic flux vector control is selected in Pr. 80, the settings of Pr. 0 and Pr. 46 are invalid.

Pr.18 High speed maximum frequency

You can limit the motor speed.

￿Clamp the upper and lower limits of the output frequency.

￿When you want to perform operation above 120Hz, set the upper limit of the output frequency to Pr. 18 .

(When Pr. 18 is set, Pr. 1 automatically switches to the frequency of Pr. 18. When Pr. 1 is set, Pr. 18 is automatically changed to the

frequency set in Pr. 1.)

￿Used to adjust the inverter outputs (voltage, frequency) to the motor rating.

￿When operating a standard motor, generally set the rated frequency of the motor to Pr. 3 Base frequency. When running the motor using commercial power supply-inverter switch-over operation, set Pr. 3 to the same value as the power supply frequency.

￿When you want to change the base frequency when switching multiple motors with one inverter, use the Pr. 47 Second base frequency.

￿Use Pr. 19 Base frequency voltage to set the base voltage (e.g. rated motor voltage).

Peripheral Devices	Why energy		savings?
Standard		Specifications

Can be used to change the preset speed in the parameter with the contact signals.

Any speed can be selected by merely turning on-off the contact signals (RH, RM, RL, REX signals).

￿The inverter operates at frequencies set in Pr. 4 when RH signal is on, Pr. 5 when RM signal is on and Pr. 6 when RL signal is on.

￿Frequency from speed 4 to speed 15 can be set according to the combination of the RH, RM, RL and REX signals. Set the running frequencies to Pr. 24 to Pr. 27, Pr. 232 to Pr. 239. (In the initial value setting, speed 4 to 15 are unavailable.)

￿Set a larger value for a slower speed increase/decrease or a smaller value for a faster speed increase/decrease.

￿Use Pr. 7 Acceleration time to set the acceleration time required to reach Pr. 20 Acceleration/deceleration reference frequency from 0Hz.

￿Use Pr. 8 Deceleration time to set the deceleration time required to stop from the Pr. 20 Acceleration/deceleration reference frequency.
