5 SETUP AND PROCEDURES BEFORE OPERATION
Positive logic
1)
For multiple of 1 setting
Forward run
Command pulse output
A phase
(A )
B phase
(B )
When B phase is 90
behind A phase
2)
For multiple of 4 setting
Forward run
Command pulse output
A phase
(A )
B phase
(B )
When B phase is 90
behind A phase
* A phase is output from the "PULSE F(+/-)" external I/O signal and B phase from "PULSE R(+/-)". (Refer to
"Section 3.4.3".)
5 - 16
(3) A phase/B phase mode
Forward run and reverse run are controlled with the phase difference of the A
phase and B phase.
Reverse run
Command pulse output
When B phase is 90
ahead A phase
Reverse run
Command pulse output
When B phase is 90
ahead A phase
[Switch 2] Pulse output logic selection, deviation counter clear output
logic selection
Set the pulse output signal (PULSE F/PULSE R) logic and deviation counter
clear output signal (CLEAR) logic according to the externally connected device.
