YASKAWA MANUAL NO. TOE-S616-60. 2 Preface This manual is designed to ensure correct and suitable application of Varispeed G7-Series Inverters. Read this manual before attempting to install, operate, maintain, or inspect an Inverter and keep it in a safe, convenient location for future reference. Before you understand all precautions and safety information before attempting application. General Precautions · The diagrams in this manual may be indicated without covers or safety shields to show details. [. . . ] · If the motor response is low, decrease the set value. Hunting-prevention Function The hunting-prevention function suppresses hunting when the motor is operating with a light load. This function can be used in V/f without PG and V/f with PG. Related Constants Name Constant Number Change during Operation Control Methods V/f V/f with PG Open Loop Vector 1 Flux Vector Open Loop Vector 2 Display Hunting-prevention function selection Description Setting Range Factory Setting N1-01 Hunt Prev Select 0: Hunting-prevention function disabled 1: Hunting-prevention function enabled The hunting-prevention function suppresses hunting when the motor is operating with a light load. This function is enabled in V/f control method only. If high response is to be given priority over vibration suppression, disable the hunting-prevention function. 0 or 1 1 No A A No No No N1-02 Set the hunting-prevention gain multiplication factor. Normally, there is no need to make this setting. Make the adjustments as follows: · If vibration occurs with light load, increase the setting. Hunt Prev Gain · If the motor stalls, reduce the setting. If the setting is too large, the voltage will be too suppressed and the motor may stall. Hunting-prevention gain 0. 00 to 2. 50 1. 00 No A A No No No 6-36 Improved Operating Efficiency Stabilizing Speed (Speed Feedback Detection Function) The speed feedback detection control (AFR) function measures the stability of the speed when a load is suddenly applied, by calculating the amount of fluctuation of the torque current feedback value, and compensating the output frequency with the amount of fluctuation.

Normally, there is no need to make this setting. Adjust this constant as follows: · If hunting occurs, increase the set value. · If response is low, decrease the set value. Adjust the setting by 0. 05 at a time, while checking the response. 0. 00 to 10. 00 1. 00 No No No A No No N2-02 Speed feedback detection control (AFR) time constant AFR Time Set the time constant to decide the rate of change in the speed feedback detection control. 0 to 2000 50 ms No No No A No No 6-37 Machine Protection This section explains functions for protecting the machine. Reducing Noise and Leakage Current The switching frequency of the Inverter's output transistor can be changed to reduce carrier noise and leakage current from the motor.
