P2
vector control parameter
61
In vector control mode, the output of the speed loop regulator is the torque current
command, which is used to filter the torque command. This parameter generally does not
need to be adjusted. When the speed fluctuates greatly, the filtering time can be
appropriately increased. If the motor oscillates, the parameter should be appropriately
reduced. The speed loop filter time constant is small, the inverter output torque may fluctuate
greatly, but the speed response is fast.

During deceleration ,the overexcitation control can suppress the rise of the bus voltage
and avoid overvoltage faults. The larger the overexcitation gain, the stronger the
suppression effect.
In the case where the inverter is easy to overvoltage alarm during the deceleration
process, it is necessary to increase the overexcitation gain. However, the overexcitation
gain is too large, which tends to cause an increase in the output current, which needs to be
weighed in the application.
For applications where the inertia is small, there is no voltage rise during motor
deceleration. It is recommended to set the overexcitation gain to 0. For those with braking
resistors, it is also recommended to set the overexcitation gain to 0.

In the speed control mode, the maximum value of the inverter output torque is
controlled by the torque upper limit source.
P2-09 is used to select the setting source of the upper torque limit. When it is set by
analog quantity, pulse and communication, the corresponding setting of 100%
corresponds to P2-10, and 100% of P2-10 is the rated torque of the inverter.
