Expansion encoder parameters.
“Expansion” means that when the encoder PG2 is used for the output, it can be used together with the
pulse input signal of the external equipment to perform the frequency division output for the output pulse
of the drive. If the division coefficient is set as 1, there is no frequency division; if the division coefficient is
set as 2, divide the division coefficient with the number of input pulses, and the final value will be the
output value, and so on.
It is used to define the PG wire-break detection time.
If P04.15=0, it indicates that the PG wire-break will not be detected, and the Er.PG1 will be shielded.
0: Coast to stop(Er.PG1)
Under the vector control with PG or V/F control with PG, if the PG wire is broken, the drive will report fault,
and Er.PG1 will be displayed. At the same time, the drive will stop output, and the motor will coast to stop.
1: Switch to SVC running
Switch to the open loop running mode.
6.6 Speed control parameters (Group P05)
Adjust the proportional gain and integral time for the speed loop. Function codes of P05.00~P05.09 are
enabled under the vector control mode and PG V/F control mode, and they represent the PI parameters
of motor 1 at high speed and low speed.
P05.00 and P05.01 are parameters when the running frequency is less than the ASR switching frequency
1 (P05.03); P05.04 and P05.05 are parameters when the running frequency is higher than the ASR
switching frequency 2 (P05.07). When the running frequency is between the switching frequency 1 and
switching frequency 2, it means the linear switching of those two sets of PI parameters.
Increasing the proportional gain P can accelerate the dynamic response of the system, but if the P value
is too large, it is easy to cause the oscillation of the system. Decreasing the integral time I can accelerate
the dynamic response of the system, but if the I value is too small, it is easy to cause the overshoot and
