Inovance MD800 Series Function Guide

Parameter Group
-313-
When the difference between the detected motor speed and the frequency reference exceeds the
value of F9-73 (excessive speed deviation threshold) for longer than the time set by F9-74 (excessive
speed deviation detection time), the AC drive reports E42.00 (excessive speed deviation) and handles
the fault as defined by F9-50 (fault protection action).
If F9-73 (excessive speed deviation threshold) is set to 0.0% or F9-74 (excessive speed deviation
detection time) is set to 0.0s, the excessive speed deviation detection function is disabled.
This function is available only when the AC drive works in SVC mode (F0-01 = 0).
F9-74
Excessive speed deviation detection time
Address:
63818
Min.:
0.0
Unit:
s
Max.: 60.0 Data type: UInt16
Default:
5.0
Change:
At once
Value Range:
0.0s to 60.0s

F9-75
Power dip ride-through gain
Address:
63819
Min.:
0
Unit:
-
Max.: 100 Data type: UInt16
Default:
40
Change:
At once
Value Range:
0 to 100
Description
This parameter is valid only in the "keep bus voltage constant" mode (F9-59 = 1).
If undervoltage occurs frequently during power dip ride-through, increase the power dip ride-through
gain and integral coefficient.
F9-76
Power dip ride-through integral
Address:
63820
Min.:
0
Unit:
-
Max.: 100 Data type: UInt16
Default:
30
Change:
At once
Value Range:
0 to 100
Description
This parameter is valid only in the "keep bus voltage constant" mode (F9-59 = 1).
If undervoltage occurs frequently during power dip ride-through, increase the power dip ride-through
gain and integral coefficient.
F9-77
Deceleration time of power dip ride-through
Address:
63821
