7 Digital Reference Selection197 Digital Reference SelectionSet the input for the digital references using the following constants.• Sn-26 for VS-676VG3/VH3 series Inverters• F3-01 for Varispeed G7/F7 and Varispeed AC series InvertersWith the selection switch S1 on DI-16H2, the digital reference can be set as follows.• [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). VS-616H3If selecting the contents in table 2 to the digital reference, Cn-20 must be set to 0 or 1 inadvance. (Factory setting is 0.)* 1. In BCD input, the most significant digit can be set from 0 to 15, while the other digits can beset 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 inputinstead.* 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.Table 2 Digital Reference SelectionSystemConstantNo.Setting Digitalreference *1Setting range *2 FactorysettingNoteS1 = 16 bits:Binary 16 bits/BCD 4 digitsS1 = 12 bits:Binary 12 bits/BCD 3 digitsSn-26 0000 BCD 1% 0 to 109% 0 to 109% 0000 *10001 BCD 0.1% 0.0 to 109.0% 0.0 to 109.0%0010 BCD 0.01% 0.00 to 109.00% 0.00 to 15.99%0011 BCD 1 Hz 0 to 400 Hz 0 to 400 Hz *10100 BCD 0.1 Hz 0.0 to 400.0 Hz 0.0 to 159.9 Hz0101 BCD 0.01Hz 0.00 to 159.99 Hz 0.00 to 15.99 Hz0111 Binary100%/300000.00 to 109%/0 to 327000.00 to 100%/0 to 4095*31000
