Analogue Comparator 1 Level High
[612]
Selects the analogue comparator constant high level accord-
ing to the selected value in menu [611].
The default value is 300.
Communication information
Example
This example describes the normal use of the constant level
high and low.
No. Description
1
The reference signal passes the Level LO value from
below (positive edge), the comparator CA1 output stays
low, mode=RUN.
2
The reference signal passes the Level HI value from
below (positive edge), the comparator CA1 output is set
high, mode=RUN.
3
The reference signal passes the threshold level of 4 mA,
the motor speed will now follow the reference signal.
T
During this period the motor speed will follow the refer-
ence signal.
4
The reference signal reaches the threshold level, motor
speed is 0 rpm, mode = RUN.
5
The reference signal passes the Level HI value from
above (negative edge), the comparator CA1 output stays
high, mode =RUN.
6
The reference signal passes the Level LO value from
above (negative edge), the comparator CA1 out-
put=STOP.
