Interrupt input via PLC (BFM)

In the interrupt 1-speed positioning operation, the interrupt stop operation, the interrupt 2-speed positioning
operation, and the external command positioning operation, interrupt input (INT0, INT1) via PLC (BFM) can
be used.
When interrupt input via PLC (BFM) is used, select a terminal to be used for the interrupt input in the interrupt
input setting BFM#3 (b3, b2), BFM#37 (b3, b2) and turn on operation command II BFM#57 (b1, b0) by the
PLC input.

Point
Connect and link an arbitrary input of the PLC (X000, X001, etc.) to the INT0 (b0), INT1 (b1) of the operation
command II (BFM#57).
Response time
Response time of INT0, INT1 is as follows.
• During operation at 1 kHz or higher: within 3 ms
• During operation at less than 1 kHz: within 3 pulses
Caution of interrupt input is used
When both INT0 and INT1 are set to ON at the same time in the external command positioning or interrupt 2-
speed positioning, INT0 is effective.

Interrupt input 1 (INT1) via PLC is used for interrupt input 1.
Interrupt input 0 (INT0) via PLC is used for interrupt input 0.
STOP
The STOP terminal is used for interrupt input 1.
Interrupt input 0 (INT0) via PLC is used for interrupt input 0.
INT1
Interrupt input 1 (INT1) via PLC is used for interrupt input 1.
-1PG are used for DOG and STOP.
