(percentage) * F13.09
F13.08=5: High-Frequency Pulse Input (X7)
Under the torque control mode, the upper limit frequency is set through HDI
(percentage) * F13.09
Please refer to the description of F00.04 for detailed explanations of AI1-AI4 and
X7. F00.04 has the same meanings as AI1-AI4 and X7. 100.00% is the percentage
inputted through F13.09 (Upper Limit Frequency of Torque Control)
F13.08=6 or 7: Communication Setting of Torque Control Upper Limit
Frequency
For master-slave communication (F10.05=1) and the inverter is slave (F10.06=0) the
upper limit frequency is 700FH (Communication Setting) * F10.08 (proportional
coefficient) * F00.18 (upper limit frequency). The range of 700FH is 100.00% to
100.00%. Details are shown at table 12-2.
For general communication (F10.05=0)
F13.08=6, the upper limit frequency is 700BH (Communication Percentage Setting)
* F13.09 (upper limit frequency)
F13.08=7, the upper limit frequency is 7018H (Communication Setting)
The range of 700BH is 0.00% to 200.00%. The range of 7018H is 0.00 to F00.16
(maximum frequency).
The upper limit frequency of torque control mode is used to set forward or reverse
maximum frequency of the inverter.
For torque control mode if the load torque is less than the motor output torque, the
motor speed will continue to rise, to prevent mechanical systems appear coasters and
other accidents, must limit the highest motor speed; Even if the load is greater than the
motor output torque and the motor will be reversed. If F13.19 is set to 1 motor run
highest load frequency is still limited, if F13.19 is set to 0 means that the highest motor
running load frequency is not restricted.
The reverse upper limit frequency is decided by F13.09 * F13.18.
For example, Torque reference is positive, torque control upper limit frequency is
