High-function General-purpose Inverter RX2 Series User’s Manual
Automatic torque boost control is used when a motor with an encoder is driven; that require a certain
torque at the start; and when the motor revolution speed needs to be equal to the command speed.
The feedback of the encoder signal from the motor allows highly accurate frequency control.
As for adjustment of the automatic torque boost control, refer to 7-2-6 Automatic Torque Boost on page
7-12.
In the V/f control with feedback (FB), a correction of PI control is conducted on the command frequency
for the fed-back frequency to control the motor.
Precautions for Correct Use
• When [CA-90] = 02, Input terminals [A] and [B] are switched to the terminals for feedback
control. When [CA-90] ≠ 02, terminals [EA] and [EB] of the feedback option RX2-PG01 are
enabled.
•See 7-2-16 Encoder Feedback Control on page 7-37.
