Chapter 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] New speed 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.
4: High speed input request
The external command signal input is used to execute the mark
detection. And, also set to use the external command signal in the
synchronous control.
POINT
To enable the external command signal, set the "[Cd.8] External command valid" 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 Section 13.7.10 "Speed control 10 x multiplier setting for degree axis
function" about speed control 10 x multiplier setting for degree axis.
