13.7.10 Speed control 10 x multiplier setting for degree axis function
The "Speed control 10 x multiplier setting for degree axis function" is executed the
positioning control by 10 x speed of the setting value in the command speed and the
speed limit value when the setting unit is "degree".
This section explains the "speed control 10 multiplier specifying function for degree
axis" as follows:
[1] Control details
[2] Setting method of "Speed control 10 x multiplier setting for degree axis function"
[1] Control details
When "Speed control 10 multiplier specifying function for degree axis" is valid,
this function related to the command speed, monitor data, speed limit value, is
shown below.
(1) Command speed
(a) Parameters
• "
Pr.7
Bias speed at start"
• "
Pr.46
OPR speed"
• "
Pr.47
Creep speed"
•
"
Cd.14
New speed value"
•
"
Cd.17
JOG speed"
• "
Cd.25
Position-speed switching control speed change register"
• "
Cd.28
Target position change value (new speed)"
•
"
Cd.140
Command speed at speed control mode
"
•
"
Da.8
Command speed"
(b) Major positioning control
1) For "2 to 4 axis linear interpolation control" and "2 to 4 axis fixed-feed
control", the positioning control is performed at decuple speed of
command speed, when "
Pr.83
Speed control 10 x multiplier setting for
degree axis" of reference axis is valid.
2) For "2 to 4 axis speed control", " Pr.83
Speed control 10 x multiplier
setting for degree axis" is evaluated whether it is valid for each axis.
If valid, the positioning control will be performed at decuple speed of
command speed.
