12 CONTROL SUB FUNCTIONS
(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 HF-KP (262144PLS/rev)
AP = 262144 .. Pr.2
AL = 262144 .. 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 HF-KP (262144PLS/rev) and
the reduction ratio of the reduction gear is 3/11
First, find how many degrees the load (machine) will travel (
motor turns one revolution (AP).
•
AP(No. of pulses per rotation) = 262144
•
S
(Machine travel value per motor revolution)
Substitute this for the above expression (1).
