Version Upgrade Information
The following tables outline changes made for the most recent version upgrade for SYSMAC CJ-Series
Position Control Units.
■
Enhanced Functions for Unit Version 2.0
Changing Multiple-start Acceleration for Relative and Absolute Move-
ment during Direct Operation
Changing Accelerations/Decelerations and Changing Deceleration Fol-
lowing Interrupt Inputs for Interrupt Feeding during Direct Operation
Allowing Changes to Acceleration/Deceleration Time during Jogging
Setting Acceleration/Deceleration Time in Axis Parameters as Time Re-
quired to Reach Target Speed
Addition of Easy Backup Function
Previous version Present version (Ver. 2.0 or later)
When executing multiple starts during direct
operation, the acceleration/deceleration times
set for the first start were used. When executing multiple starts during direct operation, the acceler-
ation time set for each of the multiple starts is used and the decel-
eration time set for the first start is used.
Previous version Present version (Ver. 2.0 or later)
The speed command could be changed as
long as it was done before the interrupt signal
was input. If an acceleration/deceleration time
was changed, the change would not be effec-
tive until the next interrupt feed command. The
acceleration/deceleration times set for the first
start were used for speed changes. The decel-
eration time set for the first start was used after
interrupt signal input. The acceleration/deceleration times can be changed and changes
can be made with the speed command as long as the changes are
made before the interrupt signal is input. The acceleration/deceler-
ation times can also be changed during acceleration and decelera-
tion. The deceleration time set for when the interrupt input occurs is
used following interrupt signal input.
Previous version Present version (Ver. 2.0 or later)
The only speed changes allowed during jog-
ging were those made with the speed com-
mand. If acceleration/deceleration times
changed, the changes were not effective until
the next JOG command. The deceleration time
set when the JOG operation was started was
used for accelerations/decelerations for speed
changes as well as for JOG stops or decelera-
tion stops. In addition to changes made during JOG operation with the speed
command, speed changes can also be made during JOG operation
by changing the acceleration/deceleration times. Accelera-
tions/decelerations can also be changed during acceleration/decel-
eration. Accelerations/decelerations can also be changed during
acceleration/deceleration to a fixed speed. The deceleration time
set when the stopping the JOG operation is executed is used for
JOG stops or deceleration stops.
Previous version Present version
Acceleration/deceleration times could be set
only as the time required for each axis to go
from the initial speed to the maximum speed. The acceleration/deceleration time can be set in one of the follow-
ing ways.
• Set as the time required for each axis to go from the initial
speed to the maximum speed (previous setting method).
• Set as the time required for each axis to go from the present
speed to the target speed. (This simplifies calculating acceler-
ation/deceleration times.)
Previous version Present version
There was no easy backup function. The easy backup function of the CPU Unit can be used to automat-
ically back up and restore the following data from/to flash memory
in the PCU along with all data from the CPU Unit using a Memory
Card in the CPU Unit. It can also compare the data. This makes it
easier to back up all PLC data or to prepare backup data in case
Units are replaced.
• Axis parameters
• Sequence data
• Speed data
• Acceleration/deceleration time data
• Dwell time data
• Zone data
Note Data for all Unit axes is stored at the same time.
