12. (M) Item and Output Signal for Monitoring
12.7 Output frequency detection
NOTE
• All signals are OFF during the DC injection brake operation and during tuning at start-up.
• The reference frequency in comparison with the set frequency differs depending on the control method.
• Setting a higher value in
Pr.870
causes a lower responsivity of the signals for frequency detection (SU, FB, and LS signals).
• The logic (ON/OFF switching) of the LS signal is the reverse of that of the FB signal.
• Changing the terminal assignment using
Pr.190 to Pr.196 (Output terminal function selection)
may affect the other
functions. Set parameters after confirming the function of each terminal.
