Similarly when the speed limit command is smaller than Pr. 13 Starting frequency , thespeed limit value is 0Hz.⋅ When speed limit is to be made using analog input, perform calibration of the analog input terminal 1, 2 and 4. (Refer to page273.)CAUTIONWhen speed limit is to be made using the analog command (terminal 1,2,4), turn off the external signals (RH, RM, RL). If any ofexternal signals (RH, RM, RL) is on, multi-speed limits are made valid.(3) Set the forward rotation and reverse rotation individually (Pr. 807 = "1")Set the speed limit during foward rotation using Pr. 808 Forward rotation speed limit and the speed limit during reverserotation using Pr. 809 Reverse rotation speed limit.The speed during forward and reverse rotation is limited at the setting value of Pr. 808 when "9999" (initial value) is setin Pr. 809 .Speed limitSpeedTorque controllable rangeForward rotationForward rotationPr. 808Pr. 7 Pr. 8Speed limitPr. 808Output torque(%)Speed limit150 1500Pr. 809Reverse rotationSpeed limitReverse rotationTimePr. 809Torque controllable rangeSTF(STR) ON OFF111
Torque control by real sensorless vectorcontrol, vector control(4) Forward rotation/reverse rotation speed limit (Pr. 807 = "2")⋅ When making a speed limit using analog input from terminal 1, the speed limit of the forward and reverse rotationcan be switched according to the polarity of voltage.⋅ Forward/reverse rotation speed limit is made valid when Pr. 868 Terminal 1 function assignment = "5".⋅ For 0 to 10V input, set the forward rotation speed limit. The reverse rotation speed limit at this time is the value ofPr.1 Maximum frequency.⋅ For -10 to 0V input, set the reverse rotation speed limit. The forward rotation speed limit at this time is the value ofPr. 1 Maximum frequency .⋅ The maximum speed of both the forward and reverse rotations is Pr. 1 Maximum frequency .When terminal 1 input is "-10 to 0V" When terminal 1 input is "0 to 10V"SpeedTorque controllable rangeForward rotationPr. 1SpeedForward rotation150 0 150Output torque (%)150 0 150Terminal 1 inputTerminal 1inputOutputtorque (%)Reverse rotationPr. 1Torque controllable rangeReverse rotationSpeedPr. 1The forward rotationspeed limitTorque controllable rangeSpeedTerminal 1 input (0 to 10V)The forward rotation speedlimitPr. 7Torque controllable rangePr. 8Terminal 1 input(-10 to 0V)The reverserotation speedlimitPr. 7Pr. 8TimePr. 1The reverse rotationspeed limitTimeStart signalOFFONStart signal OFFONREMARKS⋅ When making speed limit from terminal 1, make calibration of terminal 1.
