8-4 Procedures for Setting Data for Memory Operation
The procedures for setting data for memory operation are explained below using
the X axis as an example.
1. Setting the common parameter area (Refer to 4-2 Common Parameter Area .)
m: Determines whether DM or EM is made of the operating data area.
m+1: Sets the beginning word (I) of the operating data area.
m+2: Designates the mounting position and parameters.
2. Powering up again or re-starting
The data in the common parameter area set in (1) above is enabled.
3. Transferring the data (Refer to Section 5 Transferring and Saving Data .)
Transfer the data set for the common parameters and for the axes to the Position
Control Unit.
4. Executing START
Set the sequence number for beginning operation (word n+1, bits 00 to 07).
Turn ON the Sequence Number Enable Bit (word n, bit 00).
Turn START (word n, bit 01) or INDEPENDENT START (word n, bit 02) from
OFF to ON.
The operations in (1) and (2) above are required when using a Position Control
Unit for the first time, or when modifying the data in the common parameter area.
8-5 Timing Chart for Memory Operation
This section provides timing charts showing START and INDEPENDENT
START execution. The X axis is used as an example. It is first necessary to
understand the functions of the Busy Flag and the Sequence Number Enable
Bit.
