6:
Frequency Command (00-05)
Note:
Parameter only active when frequency command selection (00-05) is set to 5.
When 10-00=1 or 2
,
Source of signal is proportional to be corresponding to PID target via analog input terminal.
For example:
0~10V is corresponding to 0~100% target value. When being given 2V, 20% target value is obtained.
When 10-00=3
,
PID target value is pulse input. The proportion of pulse input is set depending on the parameters of 03-30 (pulse
input scales) ~ 03-34 (pulse input filter time).
For general purpose of PID setting, set 10-00=4 to set the PID target value.
When 10-00=4
10-02(PID target value) is set at percentage and PID setting is at main screen monitor (12-38).
Maximum target value is set by parameter 10-33 (PID feedback maximum value), the decimals is determined by
parameter10-34 (PID decimal width), and the unit is set by parameter 10-35 (PID unit).
Ex:
Set 10-33 = 999, 10-34 = 1, 10-35 = 3, and set 10-02 to 10%
Then 9.9PSI is displayed at the main screen monitor (12-38) and can be modified at this monitor. Maximum value
is 99.9 PSI (limited to the setting value of parameter 10-33).
When 10-00=6
The current frequency command is proportional to be corresponding to PID target.
