VLT ® 2000 Series The control possibilities of the VLT I Operation and display (group 0..) In this group you will find parameters concerning the display read-out, local operation and setup handling. The settings of parameters 101-112 will be suitable for normal applications using standard induction mo- tors at constant torque load without parallel-coupled motors. Note: The choice between the 10 different display read-outs mentioned on page 48 is not an element of this group. Open loop: If parallel-coupled motors are used on a VLT frequency converter output terminal, or any synchronous type of motor is used, select the open loop mode.
Further adjustments may improve the effective torque or give a more accurate speed, if the motor data deviates from the typical standard values. Manual tuning is possible in parameters 107-112 for adjustment of values. I Load and motor (group 1) This group of parameters has been reserved for the adjustments necessary to adapt the VLT frequency converter to the required application and motor.
