Name R/W
R/W Two options; select codes:
00... Edge detection
01... Level detection
R/W Sets a limit on output
frequency less than the
maximum frequency (A004).
R/W
Range is from frequency lower
limit (A062) to maximum
frequency (A004).
0.0.. setting is disabled
>0.1 setting is enabled
R/W Sets a limit on output
frequency greater than zero.
Range is start frequency
R/W
(B082) to frequency upper
limit (A061).
0.0.. setting is disabled
>0.1 setting is enabled
R/W 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
R/W Defines the distance from the
center frequency at which the
jump around occurs
Range is 0.0 to 10.0 Hz
R/W Enables PID function,
two option codes:
00... PID Disable
01... PID Enable
R/W Proportional gain has a range
of 0.2 to 5.0
R/W Integral time constant has a
range of 0.0 to 150 seconds
R/W Derivative time constant has a
range of 0.0 to 100 seconds
R/W Process Variable (PV) scale
factor (multiplier), range of
0.01 to 99.99
R/W Selects source of Process
Variable (PV), option codes:
00... [OI] terminal (current in)
01... [O] terminal (voltage in)
02... Network
03... Calculate function output
