PCX allows the more user friendly turns to be entered by transposing.
N
TURNS
= SR1
And then sends to the drive the required value of SR1. If the computed value of SR1 has a
fractional remainder, it will round it off and display the closest possible value to your entry.
Example:
You enter a value of 3, meaning you would like 3 turns of the follower axis for every turn of the
lead.
PCX computes
4000
3
(Assume encoder for lead axis) = 1333 1/3
The 1/3 is dropped
4000
1333
= 3.0007502 = TURNS
This is the closest possible ratio based on an SR1 of 1333 and an encoder of 4000.
SYNC VELOCITY SCALE FACTOR AND SYNC VELOCITY
DECIMAL POINT
These setups are provided for programming velocities which are used for synchronization.
When using the sync feature, the motor's speed is a ratio of the lead axis speed. The default
values are 1000 for sync scale factor with 3 as the decimal point. This produces a sync velocity
of 1.000 for programming INDEX and HOME. What this means is, that when synchronization
of follower axis and motor occurs (based on your sync ratio), you are at 1 to 1. These numbers
can change to suit your application.
