0x2636:002
(P430.02)
Analog input 1: Min frequency value
(Analog input 1: AI1 freq @ min)
-1000.0 ... [0.0] ... 1000.0 Hz
Denion of the seng range for operang mode "MS: Velocity mode".
•
Direcon of rotaon according to sign.
•
The standard setpoint source for operang mode 0x6060 (P301.00) =
"MS: Velocity mode [-2]" is selected in 0x2860:001 (P201.01).
4Conguring the frequency control ^ 82
0x2636:003
(P430.03)
Analog input 1: Max frequency value
(Analog input 1: AI1 freq @ max)
Device for 50-Hz mains: -1000.0 ... [50.0] ... 1000.0 Hz
Device for 60-Hz mains: -1000.0 ... [60.0] ... 1000.0 Hz
0x2636:004
(P430.04)
Analog input 1: Min PID value
(Analog input 1: AI1 PID @ min)
-300.00 ... [0.00] ... 300.00 PID unit
Denion of the seng range for PID control.
•
The standard setpoint source for the reference value of PID control is
selected in 0x2860:002 (P201.02).
4Conguring the process controller ^ 116
0x2636:005
(P430.05)
Analog input 1: Max PID value
(Analog input 1: AI1 PID @ max)
-300.00 ... [100.00] ... 300.00 PID unit
0x2636:006
(P430.06)
Analog input 1: Filter me
(Analog input 1: AI1 lter me)
0 ... [10] ... 10000 ms
PT1 me constant for low-pass lter.
•
By the use of a low-pass lter, the impacts of noise to an analog signal
can be minimised.
•
For an opmum lter eect, rst the noise frequency has to be deter-
mined. The me constant then has to be set so that it equals the
reciprocal value of the double frequency.
0x2636:007
(P430.07)
Analog input 1: Dead band
(Analog input 1: AI1 dead band)
0.0 ... [0.0] ... 100.0 %
Oponal seng of a dead band that is placed symmetrically around the
frequency zero point.
•
If the analog input value is within the dead band, the output value for
the motor control is set to "0".
•
100 % ≡ maximum value of analog input (0x2636:003 (P430.03),
0x2636:005 (P430.05), 0x2636:012 (P430.12))
•
Example: Dead band 10% of 50Hz: -10V … 10V dead band -5Hz … 5 Hz,
0 … 10V dead band 0Hz … 5 Hz
0x2636:008
(P430.08)
Analog input 1: Monitoring threshold
(Analog input 1: AI1 monit.level)
-100.0 ... [0.0] ... 100.0 %
Monitoring threshold for analog input 1.
•
100 % ≡ 10 V (with conguraon as voltage input)
•
100 % ≡ 20 mA (with conguraon as current loop)
Excepon: in the case of a congured input range 4...20mA (0x2636:001
[4]), the monitoring is triggered at 2mA with a monitoring threshold of
0.0%.
0x2636:009
(P430.09)
Analog input 1: Monitoring condion
(Analog input 1: Monitoring cond.)
Monitoring condion for analog input 1.
•
If the selected condion is met, the "Error of analog input 1 acve
[81]" trigger is set to TRUE. The trigger can be assigned to a funcon
or a digital output.
•
If the selected condion is met for at least 500 ms, the error response
set in 0x2636:010 (P430.10) takes place.
0 Input value < trigger threshold
1 Input value > trigger threshold
