Rockwell Automation Liqui-Flo DBT Reach Drive - Manual (Page 65)

Parameter Descriptions 3-39
Selects the drive’s response to increasing drive temperature and may reduce the
current limit value as well as the PWM frequency. If the drive is being used with a sine
wave filter, the filter is likely tuned to a specific carrier frequency. To ensure stable
operation, it is recommended that Drive OL Mode be set to 1 = Reduce CLim.
Sets the carrier frequency for the PWM output. Drive derating may occur at higher
carrier frequencies. For derating information, refer to Appendix A.
Important: If Motor Cntl Sel (53) is set to FVC Vector, the drive will run at 2kHz
carrier frequency when operating below 6 Hz.
Selects amount of droop that the speed reference is reduced when at full load torque.
Zero disables the droop function.
Important: Selecting “Slip Comp” with Feedback Select (80) in conjunction with
Droop RPM @ FLA may produce undesirable results.
