CDE360 Vector Control AC Drive Chapter 6 Parameters Description
Eb.14
Range: 0.0~100.0
Default: 5.0
Frequency
detection
Hysteresis 1
(FDT hysteresis1)
Unit: %
This is a percentage of the hysteresis frequency to
Eb.13
.
See the parameter description of
Eb.13
.
Eb.15
Range: 0.00~
b0.00
Default: 50.00
Frequency
detection
threshold 2
(FDT2)
Unit: Hz
If the running frequency is higher than the value of Eb.15,the Y terminal
allocated with function No.11 “FDT2 detection output” becomes ON. If the
running frequency is lower than value of
Eb.15
*(1-
Eb.16
), the Y terminal
goes OFF.See the description of Figure below.
Eb.16
Range: 0.0~100.0
Default: 5.0

hysteresis2
(FDT hysteresis2)
Unit: %
This is a percentage of the hysteresis frequency to
Eb.15
.
See the parameter description of
Eb.15

Eb.17
Range: 0.0~300.0
Default: 5.0
Zero current
detection
level
Unit: %
This is a relative value to motor rated current.
If the output current of the AC drive is equal to or less than
Eb.17
*
b0.08
(motor rated current) and the duration exceeds
Eb.18
,the Y
terminal allocated with function No.19 “Zero current status” becomes ON.
The zero current detection is shown in the following figure.
Eb.18
Range: 0.01~600.00
Default: 0.10
