11.8 H: Terminal Functions
OFF : Run command is disabled. When the drive is running, it stops according to b1-03 setting.
■
71: Torque Control
Setting Function
71 Torque Control
ON : Torque control
OFF : Speed control
Note:
When this function is enabled, set d5-01 = 0 [Torque Control Selection = Speed Control].
Input the Speed/Torque Control Switchover Time
Use parameter d5-06 [Speed/Torque Changeover Time] to set the length of time, in milliseconds, that the drive
will wait to switch between speed and torque control. When the speed/torque control switchover signal changes in
the time set in d5-06, the three analog inputs will keep their present value. Complete the signal switchover with an
external source in this time.
Note:
Refer to "Switch Speed Control and Torque Control" for more information.
■
72: Zero Servo
Setting Function
72 Zero Servo
This function will hold a stopped motor if an external force is applied or an analog reference is offset.
Note:
• Refer to "b9: Zero Servo" for more information.
• When you use the Zero Servo function, keep the Run command ON. Zero servo stops the motor and if you turn OFF the Run
command, it will not have power.
■
75: Up 2 Command
Setting Function
75 Up 2 Command
When you activate the terminal set for Up2 Command, the bias will increase. When you activate the terminal set
for Down 2 Command, the bias will decrease. When you activate or deactivate the two commands, the drive will
hold the frequency reference.
2 Command and d4-01, d4-03, d4-05.
Note:
• When using this function, set the optimal bias limit value with d4-08 and d4-09 [Up/Down 2 Bias Upper Limit/Lower Limit].
• Refer to "d4: Frequency Ref Up/Down & Hold" for more information.

V/f CL-V/f OLV
Sets the function to switch between torque control and speed control.
V/f CL-V/f OLV CLV
Sets the function to hold a stopped motor.
V/f CL-V/f OLV CLV
Sets the function to increase the frequency reference bias value to accelerate the motor when the
terminal is activated. Set this function and H1-xx = 76 [Down 2 Command] together.
