Multi-Speed Operation Function - Hitachi L300P-110L Instruction Manual

Multi-speed operation function

It is possible to set multiple operation speeds and switch between the
speeds with the terminals.
Multi-speed operation can be selected by binary operation(max. 16
speeds) with 4 terminals or by bit operation (max. 6 speeds) with 5
terminals.

(1) Binary operation
It is possible to set multi-speed 0 to 15 by selecting 02 to 05 (CF1 to CF4) on the intelligent input terminals.
Set frequency setting for speed 1 to 15 with A021-A035.
Set 0 speed with A020/A220 or F001 when frequency command is operator.
Or when frequency command is control terminal (Terminal), set with O, OI, O2 terminal.

(2) Bit operation
It is possible to set multi-speed 0 to 5 by assigning 32 to 38 (SF1-SF7) to the intelligent input terminals.
Set frequency SF1-SF7 to A021-A027.

When each terminal turns ON simultaneously, the lower
number has priority. In order for the inverter to operate both
the frequency and the RUN operation (FW,RV) must be applied.
The L300P series can allocate it to 5 biggest terminals simultaneously.
