4.3 Table Parameter Settings for Speed/Torque (Pressure) Table Operation
4.3.3 Setting Condition for Changing from Speed Table Operation to Torque (Pressure) Table Operation
4-10
Torque (Pressure) Table Operation Example 1 for Pn6A4 = n.1
During speed table operation, if the pressure feedback detection value falls to the setting for
Pn44C (Pressure Feedback Enable Level) or less, torque references are restricted to the setting
of Pn6A5 (Torque (Pressure) Reference during Speed Table Operation) or less. The pressure
reference in Pn6A5 functions as the maximum limit when the pressure feedback detection
value exceeds the value of Pn44C.
Speed table operation changes to torque (pressure) table operation when the motor position
exceeds the table operation switching position (Pn6A8). After operation changes to pressure
table operation, the pressure feedback control follows the setting in Pn44C.
In the following example, speed table operation is changed to torque (pressure) table operation
when the motor position exceeds Pn6A8 even if the pressure feedback detection value does
not exceed Pn44C.
Torque (Pressure) Table Operation Example 2 for Pn6A4 = n.1
During speed table operation, if the pressure feedback detection value falls to the setting for
Pn44C (Pressure Feedback Enable Level) or less, torque references are restricted to the setting
of Pn6A5 (Torque (Pressure) Reference during Speed Table Operation) or less. The pressure
reference in Pn6A5 functions as the maximum limit when the pressure feedback detection
value exceeds the value of Pn44C.
Speed table operation changes to torque (pressure) table operation when the motor position
exceeds the table operation switching position (Pn6A8). After operation changes to pressure
table operation, the pressure feedback control follows the setting in Pn44C.
In the following example, the pressure feedback detection value exceeds Pn44C, so the motor
operates at the pressure reference in Pn6A5. When the motor position exceeds Pn6A8, speed
table operation changes to torque (pressure) table operation.
