F2‑00 Speed loop

1–300 Asynchronous
motor: 30
Synchronous
motor: 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 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 Switchover
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,
you need to 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.
