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 torque + 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 EM730/EM730E 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 to F14.34
correspond to F01.00 to F01.34, which are motor nameplate parameters, motor parameters and
encoder parameters; the function code F14.35 corresponds to F00.01, which is used to select the
motor drive mode; the function codes F14.36 to F14.76 correspond to F06.00 to F06.40, which
are vector control parameters; and the function code F14.77 is used to select the
acceleration/deceleration time of the motor 2. Only the parameters of F14.72 are described
below. For the rest of the parameters, refer to the relevant parameters of the motor 1.
