Setting 0: Legacy Operation Mode
When S5-04 = 0 (Legacy operation mode), the HAND/OFF/AUTO functionality for both the HOA keypad and multifunction
inputs.
Setting 1: Normal Operation Mode
When S5-04 = 1 (Normal operation mode), the functionality is as follows:
• AUTO mode: Drive frequency reference and run command are based on b1-01/b1-02.
• OFF mode: Drive is stopped and cannot run (except via Emergency Override multi-function input). Frequency reference is
based on b1-01.
• HAND mode: Drive runs at frequency reference selected via S5-01.
The AUTO, OFF and HAND states are selected either via the HOA keypad or multi-function inputs.
Parameter S5-01 selects the HAND mode frequency reference source. When S5-01 is set to 2, d1-16 is used as the HAND
mode reference. When S5-01 is set to 3, S5-05 is used. When S5-01 is set to 4, the frequency reference selected via b1-01 is
used as the HAND mode reference.
The only difference between d1-16 and S5-05 is that the unit for d1-16 changes based on o1-03, o1-10 and o1-11. However,
the unit for S5-05 is fixed at Hz.
Parameter S5-03 selects whether PI control is enabled or disabled in HAND mode.
Note:
The drive will always be in AUTO mode at power up with S5-04 = 1.
