CDE500 Vector Control AC Drive
Chapter 6 Parameters Description
F0.04
Range: 0~1
Default: 0
Short-circuit to
ground upon
power-on
0: Disable
1: Enable
It is used to determine whether to check the motor is short-circuited to
ground at power-on of the drive. If this function is enabled, the drive's
UVW will output voltage for a while after power-on for check motor
insulation.
F0.05
Range: 0.30~3.00
Default: 1.00
AC drive over
load protection
gain
When the carrier frequency or the ambient temperature is low, the drive
overload capacity will enhance, increasing this parameter properly can
improve the drive overload ability.
F0.06
Range: 0~1
Default: 1
Motor overload
protection
0: Disable
1: Enable
If the motor overload protection function is enabled, protecting action will
be performed when motor current and duration exceed the threshold. The
characteristic curve of the motor overload protection is shown in figure
below. Protecting action is depended on the setting of F0.19(Thousand’s
digit).
F0.07
Range: 0.20~10.00
Default: 1.00
Motor overload
protection gain
It is defined the motor overload protection gain, the detail as shown in
figure below
.
The user can adjust the motor overload current and time by set the parameter of
F0.07
, 100%
corresponds to motor current.
For example:
If F0.07 = 1.00 and the overload gain is 120%, then:
T_120 =
（
120% - 115%
）
*
（
80 - 40
）
/
（
125% - 115%
）
+ 40 = 60(Minutes)
Assume that overload gain is 120% and 30 minutes motor overload time is expected, then:
the overload time of 30 minutes is firmed between 123% to 135% When F0.07 =
1.00 as the figure below,so the allowed overload gain is:
129% =
（
30 - 15
）
*
（
135% - 125%
）
/
（
15 - 40
）
+135%
Then the motor overload protection gain of F0.07 = 120%/129% = 0.93
