[Pr.21] Feed current value during speed control
Specify whether you wish to enable or disable the update of "[Md.20] Feed current
value" while operations are performed under the speed control (including the
speed control in speed-position and position-speed switching control).
0: The update of the feed current value is disabled
1: The update of the feed current value is enabled
2: The feed current value is cleared to zero
Note1: When the speed control is performed over two to four axes, the choice
between enabling and disabling the update of "[Md.20] Feed current 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
Set the input signal logic that matches the signaling specification of the connected
external device, "[Cd.44] External input signal operation device" or external input
signal of servo amplifier (upper/lower limit switch, proximity dog).
Negative logic
(1) The current is not flowed through the input signal contact.
(a) FLS, RLS ............ Limit signal ON
(b) DOG, DI, STOP .. Invalid
(2) The current is flowed through the input signal contact.
(a) FLS, RLS ............ Limit signal OFF
(b) DOG, DI, STOP .. Valid
Positive logic
Opposite the concept of negative logic.
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.)
Note3: If the same external input signal is set to use to "[Pr.80] External input
signal selection" or "[Pr.95] External command signal selection " for the
multiple axes "Input signal logic selection" of those axes should be the
same. Otherwise, the error "Input signal logic selection setting error" (error
code: 938) will occur when the PLC READY signal [Y0] is turned ON, and
the READY signal [X0] will not be turned ON.
Note4: When using the servo amplifier input, the logic selection setting for
FLS/RLS is ignored. (The LSP/LSN input is used for the MR-J4-GF.)
[CiA402 mode]
Chapter 5 Data Used for Positioning Control
The feed current value will not change.
(The value at the beginning of the speed control
will be kept.)
The feed current value will be updated.
(The feed current value will change from the
initial.)
The feed current value will be set initially to zero
and change from zero while the speed control is
in effect.
