"A" Function
Name
Sets a limit on output frequency greater
than zero.
Range is start frequency () to
frequency upper limit ()
0.0 setting is disabled
>0.0 setting is enabled
Sets a limit on output frequency greater
than zero.
Range is start frequency () to
frequency upper limit ()
0.0 setting is disabled
>0.0 setting is enabled
Up to 3 output frequencies can be
defined for the output to jump past to
avoid motor resonances (center
frequency)
Range is 0.0 to 400.0 Hz
Defines the distance from the center
frequency at which the jump around
occurs
Range is 0.0 to 10.0 Hz
Sets the frequency to hold acceleration,
range is 0.0 to 400.0Hz
Sets the duration of acceleration hold,
range is 0.0 to 60.0 seconds.
Enables PID function,
three option codes:
PID Disable
PID Enable
PID Enable with reverse output
Proportional gain has a range of 0.00 to
25.00
Integral time constant has a range of 0.0
to 3600 seconds.
Derivative time constant has a range of
0.0 to 100 seconds.
Process Variable (PV), scale factor
(multiplier), range of 0.01 to 99.99
Selects source of Process Variable (PV),
option codes:
[OI] terminal (current in)
[O] terminal (voltage in)
Modbus network
Pulse train input
Calculate function output
Two option codes:
PID input = SP-PV
PID input = -(SP-PV)
Sets the limit of PID output as percent of
full scale,
range is 0.0 to 100.0%
Selects source of feed forward gain,
option codes:
Disabled
[O] terminal (voltage in)
[OI] terminal (current in)
