5 DATA USED FOR POSITIONING CONTROL
Pr.21 Current feed value during speed control
Specify whether you wish to enable or disable the update of " Md.20 Current feed
value" while operations are performed under the speed control (including the
speed-position and position-speed switching control).
0: The update of the current feed value is disabled
The current feed value will not change.
(The value at the beginning of the speed control
will be kept.)
1: The update of the current feed value is enabled
The current feed value will be updated.
(The current feed value will change from the
initial.)
2: The current feed value is cleared to zero
The current feed will be set initially to zero and
change from zero while the speed control is in
effect.
Note1: When the speed control is performed over two to four axes, the choice
between enabling and disabling the update of " Md.20 Current feed value"
depends on how the reference axis is set.
Note2: Set "1" to exercise speed-position switching control (ABS mode).
Pr.22 Input signal logic selection, Pr.23 Output signal logic selection
Set the I/O signal logic that matches the signaling specification of the connected
external device.
Note1: A mismatch in the signal logic will disable normal operation. Be careful of
this when you change from the default value.
Note2: Set the manual pulse generator input logic selection (b8) to axis 1. (Setting
of any of axes 2 to 4 is invalid.)
Pr.24 Manual pulse generator input selection
Set the manual pulse generator input pulse mode. (Only the value specified
against the axis 1 is valid.)
0: A-phase/B-phase; multiplied by 4
1: A-phase/B-phase; multiplied by 2
2: A-phase/B-phase; multiplied by 1
3: PULSE/SIGN
Pr.150
Speed-position function selection
Select the mode of speed-position switching control.
0: INC mode
2: ABS mode
Note1: If the setting is other than 0 and 2, operation is performed in the INC mode
with the setting regarded as 0.
