6-2-2 Command Source of Position (Pr) Control Mode

The command sources of Pr mode are P1-15, P1-16 to P1-29, P1-30 these eight built-in parameters.
According to parameter P1-33, users can select: a) Absolute or b) Incremental position control. Using with
external I/O signals (CN1, POS0 to POS 2 and CTRG) can select one of the eight built-in parameters to be
position command. Please refer to the table below:
Position
POS2
Command
P1 0
P2 0
P3 0
P4 0
P5 1
P6 1
P7 1
P8 1
State of POS0~2: 0 indicates the contact is OFF (Normally Open)
1 indicates the contact is ON (Normally Closed)
CTRG : the instant time when the contact changes from 0 (open) to 1 (closed).
The application of absolute and incremental position control is various and multiple. This kind of position
control is equal to a simple sequence control. User can easily complete the cycle running by using the above
table. For example, the position command, P1 is 10 running and P2 is 20 running. Give the position
command P1 first and then give the position command P2. The difference between absolute and incremental
