Speed Deviation Error Detection

The speed deviation error detection judges an error when the deviation between the output frequency
and the feedback speed becomes large.
This function operates when other than "0.0" is specified for [bb-83] Speed deviation error detection
level setting.
The speed deviation is the difference between [dA-12] output frequency monitor and [dA-08] speed
detection monitor.
When the absolute value of speed deviation has exceeded [bb-83] Speed deviation error detection level
and [bb-84] Speed deviation error detection time has elapsed, it is judged as a speed deviation error.
If "00: Warning" is specified for [bb-82] Operation for speed deviation error, the inverter turns on the
Output terminal function 041 [DSE] with a speed deviation error.
If "01: Error" is specified for [bb-82] Operation for speed deviation error, the inverter turns on the Output
terminal function 041 [DSE] with a speed deviation error, and trips with [E105] Speed deviation exces-
sive error.
Precautions for Correct Use
To use this function, speed feedback by the encoder is required.

Description
Turns on the output terminal function 041
[DSE].
Turns on the output terminal function 041
[DSE], and trips with [E105] Speed deviation
excessive error.
Set the level at 100% to which the maximum
frequency is set.
Sets the time to judge the deviation to be an
error after it has excessively increased.
Displays data obtained through encoder
feedback.
Displays the frequency command given by
the inverter.
