Motor brake and stop operation
BOF signal: Brake opening request signal
BRI signal: Brake opening completion signal
Fig. 6-48: Connection example with mechanical brake (Pr. 184 = 15, Pr. 190 = 20)
The input signal terminal used differs according to the Pr. 178 to Pr. 184 settings.
The output signal terminal used differs according to the Pr. 190 to Pr. 192 settings.
The current should be within the permissible current of transistor in the inverter. (24 V/ 0.1 A DC)
NOTES
When brake sequence mode is selected, automatic restart after instantaneous power failure is
invalid.
When using this function, set the acceleration time to 1 s or longer.
Changing the terminal function using any of Pr. 178 to Pr. 184 and Pr. 190 to Pr. 192 may affect the
other functions. Make setting after confirming the function of each terminal.
