*1. If analog input (3004Hex-02Hex/3006Hex-1FHex = 1) is selected for 1st Frequency Reference Selection
(3004Hex-02Hex)/2nd Frequency Reference Selection (3006Hex-1FHex), the signal may not be judged as a
constant speed depending on the sampling condition. In this case, set 301FHex-55Hex = 0 (Output during
acceleration/deceleration and constant-speed operation), or increase the value set in the Input Terminal
[AI1] Filter (3006Hex-22Hex).
*2.
The OFF delay becomes the time obtained by adding 0.1 s to Output Terminal [DO1] OFF Delay Time
(3051Hex-0BHex) and Output Terminal [ROA, ROB] OFF Delay Time (3051Hex-0FHex).

Window Comparator/Disconnection Detection (AI1Dc)
The window comparator signal is output when the input value of the analog input terminal [AI1] is be-
tween the upper and lower limit level of the window comparator. It is useful for monitoring the analog
input at a level to detect disconnection or other faults.
Set the detection upper limit level by Analog Input [AI1] Detection Upper Limit Level
(301FHex-3AHex), detection lower limit level by Analog Input [AI1] Detection Lower Limit Level
(301FHex-3BHex) and detection hysteresis width by Analog Input [AI1] Level Detection Hysteresis
Width (301FHex-3CHex).
