Control Mode
Default: 00
Range: 00: V/Hz without encoder feedback
01: V/Hz with encoder feedback
02: Sensorless Vector without encoder feedback
03: Sensorless Vector with encoder feedback
04: V/Hz with encoder feedback and high-speed regulation
05: Sensorless Vector with encoder feedback and high-speed regulation
This parameter determines the control method of the AC drive.
The V/Hz modes (00, 01, & 04) are the basic control modes.
The Sensorless Vector modes (02, 03, & 05) allow improved torque performance
at very low speeds and improved speed regulation. These modes require Auto-
Tuning per P0.05 in order to match the characteristics of the particular motor
being used.
The encoder feedback settings (01, 03, 04, & 05) require the installation of an
optional GS3-FB feedback card in order for the drive to read the encoder signal
from the motor. (Refer to Appendix A of this manual for more information
regarding the GS3-FB.)
The high-speed regulation settings (04 & 05) enable two other parameters which
can be used to reduce system vibration:
Slip Compensation Time Constant (P2.09) and Hunting Gain (P6.37).
