*1. To enable switching to the 1st and 2nd control, allocate "12: SET (2nd control)" to either of input terminal
[DI1] to [DI7].
The frequency reference method for data selected at 1st Frequency Reference Selection
(3004Hex-02Hex) and 2nd Frequency Reference Selection (3006Hex-1FHex) is as follows.

• The forced terminal block function are given priority over the frequency reference selected at Fre-
quency Reference Selection (3004Hex-02Hex/3006Hex-1FHex). For details, refer to 8-6-3 STO
Function by Safety Input Signal on page 8-62.
Command Using Analog Voltage Input (Frequency Reference Se-
lection (3004Hex-02Hex/3006Hex-1FHex) = "1")
• Analog input can adjust the input signal by gain and bias. (Refer to 8-3-2 Analog Input Adjustment
Function on page 8-34.)
• Behavior when the analog signal is disconnected can be set at analog reference loss detection.
 Analog Reference Loss Detection
When the analog frequency reference falls to 10% or lower of the frequency reference for 400 ms,
the wiring of the analog frequency reference is judged to have become disconnected, operation is
