(Note-1): Input type from manual pulse generator/incremental synchronous encoder is switched in "
Manual pulse generator/Incremental synchronous encoder input type selection
against the axis 1 is valid.)
• 0: Differential-output type (Default value)
• 1: Voltage-output/open-collector type
(Note-2): Set the signal input form in "
(Note-3): Voltage-output/open-collector type
Connect the A-phase/PLS signal to HA, and the B-phase/SIGN signal to HB.
(Note-4): Differential-output type
Connect the A-phase/PLS signal to HAH, and the A-phase/PLS inverse signal to HAL.
Connect the B-phase/SIGN signal to HBH, and the B-phase/SIGN inverse signal to HBL.
(Note-5): Do not connect to any of the terminal explained as "No connect".
(Note-6): Set the external command signal [DI] in "
(Note-7): Do not connect to any of the terminal at LD77MS2.
(Note-8): "COM" is the common terminal of DI1, DI2, DI3 and DI4.
(Note-9): Do not use 1, 2, 14 and 15 for other than the power supply of manual pulse generator.
