№SR-ZSV00039 － 36 －Motor Business Unit, Appliances Company, Panasonic Corporation2）UsageAfter a gain switching mode for each control mode to use, and make gain switching function valid(Pr1.14=1) by Pr1.14 “2nd gain setup” to use.Switchingmode setting Condition of switching Description of gain switching0 Fixed to the first gain Fixed to 1st gain (Pr1.00 to Pr1.04).1 Fixed to the second gain Fixed to 2nd gain (Pr1.05 to Pr1.09).2 Gain switch The first gain is used when Gain switch (GAIN) is open.The second gain is used when Gain switch (GAIN) is connected to COM-.* If Gain switch (GAIN) is not assigned to any input signal, the first gain isalways used.3 Torque command If the previously used first gain has caused the absolute value of the torquecommand to exceed “Level + Hysteresis” [%], the second gain is used.If the previously used second gain has caused the absolute value of thetorque command to stay below “Level – Hysteresis” [%] for the delay time,the first gain is used again.4 Fixed to the first gain Fixed to 1st gain (Pr1.00 to Pr1.04).5 Speed command If the previously used first gain has caused the absolute value of the speedcommand to exceed “Level + Hysteresis” [r/min], the second gain is used.If the previously used second gain has caused the absolute value of thespeed command to stay below “Level – Hysteresis” [r/min] for the delaytime, the first gain is used again.5 Speed command If the previously used first gain has caused the absolute value of the speedcommand to exceed “Level + Hysteresis” [r/min], the second gain is used.If the previously used second gain has caused the absolute value of thespeed command to stay below “Level – Hysteresis” [r/min] for the delaytime, the first gain is used again.7 Position command If the first gain has been previously used and the position command is not0, the second gain is used.If the second gain has been previously used and the position command hasstayed 0 for the delay time, the first gain is used again.8 Not in-position If the previously used first gain has caused incomplete positioning, thesecond gain is used.If the previously used second gain has caused in-position state to bemaintained for the delay time, the first gain is used again.9 Actual speed If the previously used first gain has caused the absolute value of the actualspeed to exceed “Level + Hysteresis” [r/min], the second gain is used.If the previously used second gain has caused the absolute value of theactual speed to stay below “Level – Hysteresis” [r/min] for the delay time,the first gain is used again.10 Position command + actual speedIf the first gain has been previously used and the position command is not0, the second gain is used.If the second gain has been previously used, the position command hasstayed 0 for the delay time and the absolute value of the actual speed isbelow “Level – Hysteresis” [r/min], the first gain is used again.
