Fixed frequency setpoint value (P10)
Fixed frequencies have a higher priority than frequency reference
values. They can be called individually, binary coded, or via the
digital inputs DI1 to DI6 or via the sequencing control program.
Fixed frequency
You can set eight different fixed frequency setpoints (FF0 to FF7)
in the parameter group P10.
The fixed frequencies FF1 = 10 Hz, FF2 = 15 Hz and FF3 = 20 Hz
can be called via digital inputs DI3 (control signal terminal 10) and
DI4 (control signal terminal 14) in the factory setting.
The change between the individual fixed frequency values is
completed with the acceleration and deceleration times set at P6.5
and P6.6. When the FWD or REV enables are switched off, the
output frequency is immediately blocked (uncontrolled coasting).
P6.8 = 1 causes the drive to perform a controlled deceleration a.
h
The maximum permitted set value for a fixed frequency is
limited by parameter P6.4 (maximum frequency).
A fixed frequency value can go below a minimum limit
frequency set at parameter P6.3.
h
The fixed frequency values can be changed during
operation (RUN).
