KE600 Inverter Parameter Description
154
A2-30
Phase-sequence of ABZ
incremental encoder
Factory default
0
Setting range
0: forward
1: reverse
To set the phase-sequence of encoder A, B signal
A2-36
Detection time of PG cables
disconnection
Factory default
0.0
Setting range
0.0: no detection
0.1~10.00s
To set the detection time of encoder cables disconnection, if the set time is 0.0s, the inverter will not detect
whether the encoder cable is disconnected or not.
While the encoder cables are disconnected, and after the detection time of A2-36, the inverter will give
failure information of “E-20”.
A2-38
Speed loop proportional gain 1
Factory default
30
Setting range
1 ~ 100
A2-39
Speed loop integration time 1
Factory default
0.50s
Setting range
0.01s ~ 10.00s
A2-40
Low switching frequency
Factory default
5.00Hz
Setting range
0.00 ~ P2-05
A2-41
Speed loop proportional gain 2
Factory default
20
Setting range
1 ~ 100
A2-42
Speed loop integration time 2
Factory default
1.00s
Setting range
0.01s ~ 10.00s
A2-43
High switching frequency
Factory default
10.00Hz
Setting range
P2-02 ~ P0-10 (maximum frequency)
A2-38 and A2-39 are PI adjustment parameters when the running frequency is lower than low switching
frequency (A2-40). A2-41 and A2-42 are PI adjustment parameters when the running frequency is higher
than high switching frequency (A2-43). PI parameter of frequency channel between low switching
frequency and high switching frequency is linear switching between two groups of PI parameters, as
shown in the figure below:
