5 PR Mode (Indexer Table)
PR mode is a single-axis motion control function with 16-segment position table, also called indexer table. It can
save the motion control function of the controller.
5.1 PR Main Features
PR mode can mainly set the following functions:
Features
Description
Homing
The drive can detect zero position by homing processing, and confirm the zero point of
mechanical coordinate system

Select homing method: by limit switch signal, by home switch signal, auto homing after
power up, set homing point by manual;

Homing direction can be set;

Homing offset can be set;

Move to the specified position after homing;

Acc/Dec of homing velocity can be set;
Note: Control instruction can not be sent to drive during homing
JOG
JOG can be realized by external I/O or RS485 communication.

CW JOG;

CCW JOG;

JOG teaching function;

The JOG velocity and JOG Acc/Dec can be set;
Limit
Protect the machine by limiting the working area range.

Positive/negative limit switch by digital input;

Soft limit setting;

Acc/Dec limit can be set
Note: Soft limit is valid after homing completed;
Quick stop
The movement stop immediately when the quick stop input is on, which is valid at PR mode
only
PR Path
Select the PR path number by 4 digital inputs (ADD0, ADD1, ADD2, ADD3), and then start the
PR path movement by external I/O (CTRG) or RS485communication.
 Include PP mode, PV mode and HM mode
 Trigger methods include: double edge trigger (CTGR) or RS485 trigger
 Support up to 16-segment PR positioning path
 Position, velocity and Acc/Dec values can be set
 Pause time or timing time can be set
 Support interrupt, Overlapping, jump, etc.
Path Trigger
The above PR functions can be controlled by RS485
5.2 Homing / Return to Zero Position
Homing includes homing by detecting limit switch signal, homing by detecting home switch signal, set zero
position by manual, auto homing after powering on.
