13-16: Multi-step frequency terminal 1—4.
• Up to 15 speed references can be set through different logic combinations of terminals.
• The inverter can realise 15-step speed operation through the logical combinations of 4
terminals.
• The inverter can realise 7-step speed operation through the logical combinations of 3 terminals.
• The inverter can realise 3-step speed operation through the logical combinations of 2 terminals.
• The inverter can realise the switch between setting frequency and multi-step frequency through
one terminal function.
• Refer to the below table and figure. K1 is corresponding to terminal 1, K2 is corresponding to
terminal 2, K3 is corresponding to terminal 3 and K4 is corresponding to terminal 4.
