11.8 H: Terminal Functions
882 YASKAWA ELECTRIC SIEP C710617 05F YASKAWA AC Drive GA700 Technical Manual
OFF : Run command is disabled. When the drive is running, it stops according to b1-03 setting.
■ 71: Torque Control
Setting Function Description
71 Torque Control
Sets the function to switch between torque control and speed 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 Description
72 Zero Servo
Sets the function to hold a stopped motor.
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 Description
75 Up 2 Command
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.
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 11.63 gives information about the relation between operation of the Up/Down
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.
