Digital Reference Selection

Set the input for the digital references using the following constants.
With the selection switch S1 on DI-16H2, the digital reference can be set as follows.
VS-616H3
If selecting the contents in table 2 to the digital reference, Cn-20 must be set to 0 or 1 in
advance. (Factory setting is 0.)

* 1. In BCD input, the most significant digit can be set from 0 to 15, while the other digits can be
set from 0 to 9.
* 2. Setting ranges when the maximum frequency (Cn-02) is set to 400 Hz and the frequency ref-
erence upper limit (Cn-14) is set to 109%.
Upper limit for setting range is set by the maximum frequency (Cn-02) and the frequency ref-
erence upper limit (Cn-14).
Lower limit for setting range is set by the minimum frequency (Cn-07) and the frequency ref-
erence lower limit (Cn-15).
If a value outside of the setting range was entered, the upper limit or lower limit will be input
instead.
* 3. For setting 0111 and 1000, operator displays differ as below.
Setting 0111: Displays digital reference in %.
Setting 1000: Displays the value after converting binary input to a decimal value.
• Sn-26 for VS-676VG3/VH3 series Inverters
• F3-01 for Varispeed G7/F7 and Varispeed AC series Inverters
• [12] side: 12 bit binary / 3 digit BCD
[16] side: 16 bit binary / 4 or 5 digit BCD
•
• The default setting for the switch is to the [16] side (16 bit binary / 4 or 5 digit BCD).
