2.8 H: Terminal Functions
YASKAWA TOEPYAIGA8002B GA800 Drive Programming 377
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 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 Value 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 2.59 gives information about the relation between operation of the Up/Down 2 Command
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.
