KE600 Inverter Parameter Description
133
P9-67
Over speed detection value
Factory default
20.0%
Setting range
0.0~50.0% (Maximum frequency )
P9-68
Over speed detection time
Factory default
1.0s
Setting range
0.0s: no detection
0.1~60.0s
These two parameters are only valid under the close-loop vector control mode.
If the real detected speed of motor is bigger than the maximum frequency, and the excess value is bigger
than the setting of P9-67, after the duration time of P9-68, the inverter will give failure
information of “E-43”,
and then the inverter will give response according to the set of P9-50.
If the P9-68 is set as 0.0s, there is no protection for over speed.
P9-69
Speed deviation oversize
detection value
Factory default
20.0%
Setting range
0.0~50.0% (Maximum frequency )
P9-70
Speed deviation oversize
detection time
Factory default
5.0s
Setting range
0.0s: no detection
0.1~60.0s
These two parameters are only valid under the close-loop vector control mode.
If the real detected speed of motor is different with the setting frequency, and the deviation is bigger than
the setting value of P9-69, after the duration time of P9-70, the inverter will give failure information of
“E-42”, and then the inverter will give response according to the set of P9-50.
If the P9-69 is set as 0.0s, there is no protection for speed deviation.
