5 DATA USED FOR POSITIONING CONTROL
Pr.42
External command function selection
Select a command with which the external command signal should be associated.
0: External positioning start
The external command signal input is used to start a positioning
operation.
1: External speed change request
The external command signal input is used to change the speed
in the current positioning operation. The new speed should be set
in the "
Cd.14
Speed change value"
2: Speed-position, position-speed switching request
The external command signal input is used to switch from the
speed control to the position control while in the speed-position
switching control mode, or from the position control to the speed
control while in the position-speed switching control mode.
To enable the speed-position switching control, set the
"
Cd.24
Speed-position switching enable flag" to "1".
To enable the position-speed switching control, set the
"
Cd.26
Position-speed switching enable flag" to "1".
3: Skip request
The external command signal input is used skip the current
positioning operation.
POINT
To enable the external command signal, set the "
Cd.8
External command enable"
to "1".
Pr.83
Speed control 10 x multiplier setting for degree axis
Set the speed control 10 x multiplier setting for degree axis when you use
command speed and speed limit value set by the positioning data and the
parameter at "
Pr.1
Unit setting" setup degree by ten times at the speed.
0: Invalid
1: Valid
Normally, the speed specification range is 0.001 to 2000000.000[degree/min], but
it will be decupled and become 0.01 to 20000000.00[degree/min] by setting
"
Pr.83
Speed control 10 x multiplier setting for degree axis" to valid.
Note) The speed control 10 x multiplier setting for degree axis is included in
detailed parameters 2, but it will be valid at the rising edge (OFF to ON) of
the PLC READY signal (Y0).
1: Refer to the section 12.7.11 Speed control 10 x multiplier setting for degree
axis function about speed control 10 x multiplier setting for degree axis.
