Input/Output Interface Signals - Mitsubishi Electric FATEC MELSEC iQ-R Training Manual

*1. RD77MS2 does not have the connectors 2A20 to 2A1 and 2B20 to 2B1.
*2. Set the signal input form in "[Pr.24] Manual pulse generator/Incremental synchronous encoder input
selection".
*3. With the manual pulse generator/incremental synchronous encoder of voltage-output/open-collector type
Connect the A-phase/PULSE signal to HA, and the B-phase/SIGN signal to HB.
*4. With the manual pulse generator/incremental synchronous encoder of differential-output type
Connect the A-phase/PULSE signal to HAH, and the A-phase/PULSE inverse signal to HAL.
Connect the B-phase/SIGN signal to HBH, and the B-phase/SIGN inverse signal to HBL.
*5. Do not connect to any terminals explained as "No connect".
*6. Set the external command signal [DI, FLS, RLS, DOG, STOP] in "[Pr.116] FLS signal selection", "[Pr.117]
RLS signal selection", "[Pr.118] DOG signal selection", "[Pr.119] STOP signal selection" and "[Pr.95]
External command signal selection".
*7. Do not connect wires other than the signal wires of the manual pulse generator to 1A20 and 1A19.
*8. Do not use 1A(B)15 and 1A(B)14 for other than the power supply of manual pulse generator.
