(2) When "PLS (pulse)" is set as the control unit
When using PLS (pulse) as the control unit, set the electronic gear as
follows.
AP = "No. of pulses per rotation"
AL = "Movement amount per rotation"
AM = 1
Example) When the motor is the HC-MF (8192PLS/rev)
AP
= 8192 …...
Pr.2
AL
= 8192 …...
Pr.3
AM
= 1 ………..
Pr.4
(3) When "degree" is set as the control unit for a rotary axis
When the rotary axis is used, the motor is HC-SF (16384PLS/rev) and the
reduction ratio of the reduction gear is 3/11
Reduction
ratio 3/11
M
First, find how many degrees the load (machine) will travel (
S
) when the
motor turns one revolution (AP).
•
AP(No. of pulses per rotation) = 16384
•
S
(Machine travel value per motor revolution)
= 360.00000 [degree]
×
Reduction ratio
= 360.00000
×
3/11
Substitute this for the above expression (1).
