Switching between Main/Auxiliary Frequency References
The frequency reference input can be switched between terminal A1 (main) and
terminal A2 (auxiliary). When using this function:
• make sure that b1-01 is set to 0 (Digital operator for multi-speed references).
• set the terminal A2 function to auxiliary frequency (H3-10 = 2).
• set one digital input to multi-speed 1 (H1- = 3, default for S5).
The frequency reference value is read from
• terminal A1 when the digital input set for multi-speed 1 is open.
• terminal A2 when the digital input set for multi-speed 1 is closed.
Figure 1.4 shows a wiring example for main / auxiliary reference switching using
digital input S5.
