speed limit is AI1 (percentage) * F13.09 * F13.18 and that corresponding to the reverse
speed limit is AI1 (percentage) * F13.09.
Maximum operating frequency in torque control = upper frequency limit of torque
control + offset of upper frequency limit (valid only when F13.08=1 to 5), but the
maximum operating frequency is limited by the maximum frequency of F00.16.

When the motor drives an object to move, it is necessary to overcome static/dynamic
friction. You can set this group of parameters to enable the motor rotation at the specified
torque while overcoming the inherent static/dynamic friction. The motor is mainly subject
to static friction before rotation and dynamic friction after starting rotating. In short, the
output performance of the motor is related to this group of parameters.
The specific description of this group of parameters is as follows: “when the actual
frequency (estimate frequency in SVC) is less than or equal to the set value of F13.12, the
output torque is the „set F13.11 static friction torque compensation‟; and when the
actual frequency is greater than the set value of F13.12, the output torque is „set
F13.13 dynamic friction torque compensation‟”. The larger the compensation value, the
stronger the compensation force will be. The compensation percentage is equal to the
torque setting percentage.

Parameter Group of Motor 2 of F14 group
The two motors of the A90 series inverter can be switched. For the two motors, the
motor nameplate parameters, encoder parameters and VF control or vector control
parameters can be set separately, and the VF control or vector control can be selected
independently. In addition, the parameters of the two motors can be tuned separately.
All motor parameters in the second group are included in the F14 group, and the
function codes are defined the same as those in the first group. The function codes F14.00
