10.24.2 Data used for control

Symbol
Control data Cd.1
The basic parameters or OPR parameters are taken from the buffer memory at PLC
READY ON in QD74MH.
This function is used to change the part of these parameters in PLC READY ON.
The following parameters are changed by setting "1" in
request". "0" will be automatically set in "parameter change request" by QD74MH
after changing all parameters.
If there are parameters outside the range at parameter change request, an "error
code 1037" will occur and the erroneous parameters cannot be changed. In this case,
the all parameters within the setting range changed, and "0" is set in "parameter
change request".
Parameters that can be changed by the parameter change request are shown below.
• Software stroke limit upper limit value
Pr.4
• Software stroke limit lower limit value
Pr.6
• Speed limit value
Pr.10
• Acceleration/deceleration method
Pr.15
• S-curve acceleration/deceleration time constant
Pr.16
• Sudden stop deceleration time
Pr.17
• Command in-position range
Pr.20
• Target position change overrun processing selection
Pr.23
• Linear interpolation speed limit value
Pr.26
• OP address
Pr.52
• OPR speed
Pr.54
• Creep speed
Pr.56
• OPR acceleration time
Pr.58
• OPR deceleration time
Pr.59
• OP shift amount
Pr.60
• OP search limit
Pr.62
POINT
"Parameter change request" is executed for every axis. Set "1" in "
change request" for target axes to change the parameters for the multiple axes.
Set the following control data for the parameter change function.
Refer to Section 6.3 to 6.8 for the buffer memory address and details.
