5-1 Data transfer between this module and the JW50H/70H/

100H control module

256-byte special I/O data area is used for transferring data between this module and the JW50H/70H/

100H control module. I/O refresh area on which this module is mounted cannot be used for data

transfer.

The following shows the data required for each program mode. Each of these data items must be

transferred from the JW50H/70H/100H control module as block data, and are all exchanged on the

256-byte special I/O data area.

Actually, 64 bytes (block transfer read data and block transfer write data) each are assigned to the

block data read area (PS→PC) and the block data write area (PS→PC), respectively.

(See the following page.)

Data required for direct operation (open loop connection)

• Parameter 1 (block data No.00) data of each axis

• M output range data (block data No.02) only when M output is used

• Acceleration/deceleration time data (block data No.03) only when multiple acceleration/

deceleration times are set

Data required for program operation and speed control operation (open loop connection)

• Parameter 1 (block data No.00) data of each axis

• Various setting data required for program operation. M output, acceleration/deceleration time,

dwell timer, speed, position, step data, etc. (block data No.02 to No.31)

Data required for other basic operations (origin return, Move origin, jog operation, teaching, etc.)

• Parameter 1 (block data No.00) data of each axis

Data required for special control (closed loop control, absolute system)

• Parameter 2 (block data No.01) data of each axis

When building a highly reliable closed loop system or an absolute system (comprising limited

connectable servos) for holding current value data when a power interruption occurs, parameter 2

(block data No.01) must be set in all the startup methods of operation modes to described

above.

Caution (Address annotation)

• This chapter annotates addresses in special I/O data area on the JW50H/70H/100H control

module that are used by this module as follows:

N and n are the top address of special I/O data when any given I/O has been registeared.

N+*****

n+*****
