*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.
Data Frequency reference method
1 Sets the frequency reference via the analog voltage input (input terminal [AI1]).
7 Sets the frequency reference via the UP and DOWN terminals.
10 Sets the frequency reference via Pattern Operation Function Selection.
12 Sets the frequency reference via pulse train input.
13
The result of calculation of the frequency calculation function is set as the frequen-
cy reference.
14 Sets the frequency reference via EtherCAT communication.
• 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

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
