Analogue Comparator 1 Level High<br />

[612]<br />

Selects the analogue comparator constant high level<br />

according to the selected value in menu [611].<br />

The default value is 300.<br />

Default:<br />

Range:<br />

Description<br />

The reference signal passes the Level LO value from<br />

below (positive edge), the comparator CA1 output stays<br />

low, mode=RUN.<br />

The reference signal passes the Level HI value from<br />

below (positive edge), the comparator CA1 output is set<br />

high, mode=RUN.<br />

The reference signal passes the threshold level of 4 mA,<br />

the motor speed will now follow the reference signal.<br />

During this period the motor speed will follow the reference<br />

signal.<br />

The reference signal reaches the threshold level, motor<br />

speed is 0 rpm, mode = RUN.<br />

The reference signal passes the Level HI value from<br />

above (negative edge), the comparator CA1 output stays<br />

high, mode =RUN.<br />

The reference signal passes the Level LO value from<br />

above (negative edge), the comparator CA1 output=STOP.<br />
