     Measures of inverter • If a large value is set in Pr.72 PWM frequency selection, decrease the Pr.72 setting. (Noise from the motor increases.) • Increase the setting of speed (torque) setting filter Pr.822, Pr.832 (Pr.826, Pr.836). NOTE • As changing the speed (torque) setting filter will affect the response level of the inverter to the command, adjust the setting by looking at the machine movement.

  • Page 37: Motor Thermistor Interface

    MOTOR THERMISTOR INTERFACE A vector-controlled motor with thermistor (SF-V5RUT/A) detects the motor temperature with the motor-side thermistor and sends the detected temperature to the inverter as a feedback. This operation reduces fluctuation of the generated torque due to temperature changes. The detected motor temperature can be output as an output signal (Y55 signal) or be displayed on the monitor.

  • Page 38: Terminals

    NOTE • The motor temperature detection is valid for the first motor. When applying the second motor (RT signal is ON), temperature detection is not performed. • To detect temperature with FR-A8AZ, be sure to use the SF-V5RUT/A, a dedicated motor with thermistor.
