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 Value 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 Value 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. Table 2.59
and d4-01, d4-03, d4-05.
Note:
• When you use this function, use d4-08 and d4-09 [Up/Down 2 Bias Upper Limit/Lower Limit] to set the optimal bias limit value.
• Refer to "d4: Frequency Ref Up/Down & Hold" for more information.

V/f CL-V/f OLV CLV AOLV
Sets the function to hold a stopped motor.
V/f CL-V/f OLV CLV AOLV
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.
