This is the PID control parameter Kp for the speed loop,
which affects the response to the motor speed. A larger Kp
value indicates higher adjustment sensitivity and
adjustment intensity. A smaller Kp value indicates lower
adjustment sensitivity and adjustment intensity. The low‑
speed speed loop Kp is used at the low speed.
F2‑01 Speed loop
integral time 1
0.01s to
10.00s
0.50s The reciprocal of the speed loop integral time constant is
the integral gain. The speed loop integral time constant
affects the steady‑state speed error of the motor and the
stability of the speed loop system. Increasing the speed
loop integral time constant slows down the response of the
speed loop. In this case, increase the speed loop
proportional gain to shorten the response time of the speed
loop. The low‑speed speed loop Ti is used at the low speed.
F2‑02 Switching
frequency 1
0.00 Hz to F2‑
05
5.00 Hz The speed loop PI parameters are divided into low‑speed
and high‑speed groups. If the running frequency is lower
than F2‑02 (switching frequency 1), the speed loop PI
adjustment parameters are F2‑00 and F2‑01. If the running
frequency is higher than F2‑05 (switching frequency 2), the
speed loop PI adjustment parameters are F2‑03 and F2‑04.
If the running frequency falls between switching frequency
1 and switching frequency 2, speed loop PI adjustment
parameters are switched between F2‑00/F2‑01 and F2‑03/
F2‑04. The parameter value must be lower than F2‑05
(switching frequency 2).
F2‑03 Speed loop
proportional gain 2
1–300 20 This is the PID control parameter Kp for the speed loop,
which affects the response to the motor speed. A larger Kp
value indicates higher adjustment sensitivity and
adjustment intensity. A smaller Kp value indicates lower
adjustment sensitivity and adjustment intensity. The high‑
speed speed loop Kp is used at the high speed.
F2‑04 Speed loop
integral time 2
0.01s to
10.00s
1.00s The reciprocal of the speed loop integral time constant is
the integral gain. The speed loop integral time constant
affects the steady‑state speed error of the motor and the
stability of the speed loop system. Increasing the speed
loop integral time constant slows down the response of the
speed loop. In this case, increase the speed loop
proportional gain to shorten the response time of the speed
loop. The high‑speed speed loop Ti is used at the high
speed.
