Note 10 When this parameter is “0” slip compensation will be disabled when the motor is operating above its base speed. The motor voltage will not be reduced above base
speed.
Note 11 Open Loop Vector: When this parameter is set to “1” the motor voltage will be reduced slightly when the motor is operating above 90% base speed. Slip Compensa-
tion is enabled. Speed control accuracy is improved. This may prevent speed instabilities due to motor voltage saturation. This setting may improve speed regulation
however motor torque/amp will be reduced by up to 10% due to motor voltage reduction above base speed. Flux Vector: Torque linearity is improved.
