Operation In Combination With The Simple Cam - Mitsubishi MR-JE-200A Instruction Manual

6. APPLICATION OF FUNCTIONS

6.1.5 Operation in combination with the simple cam

(1) Encoder following function
The servo amplifier receives A/B-phase output signal from a synchronous encoder and starts the servo
motor with the signal.
Up to 4 Mpulses/s can be inputted from the synchronous encoder to use with the servo amplifier.
(2) Command pulse input through function
The command pulse input through function allows the first axis to output A/B-phase pulses received from
the synchronous encoder to the next axis, enabling a system in which the second and later axes are
synchronized with the conveyor axis.

POINT
It takes about 150 µs at a maximum per axis to execute the function from
inputting to outputting of pulses.
Example) When the final axis is n
Maximum delay time [µs] = 150 µs × (n-1)
