[Default value]
Description
FA-00 Control mode
S-P, P-S,S-t,
t-S,t-P, P-t
[P-S]
Set this parameter to "P-S (position control)".
FA-01
Position sensor
wire breaking
detection
on, OFF
[on]
Selects whether to make an alarm trip when a position
sensor error occurs (or wire breakage or open circuit fault is
detected).
When this parameter is set to "on", an alarm trips if a
position sensor error (E39) is detected.
When set to "OFF" no alarm will trip even if a position
sensor error (E39) occurs.
Even when set to "OFF", a position sensor error (E39)
occurs if a counter error is detected by the position sensor.
A position sensor error (E39) also occurs at servo ON if
power has been turned on without the position sensor
connected, regardless of this parameter setting.
Set this parameter to "on" in normal operation, and do not
set to "OFF" except in case of emergency.
FA-02
Allowable time of
power failure
0.00, 0.05 to 1.00
(s)
[0.00]
Sets the allowable time for momentary power outage (main
circuit power supply shut-off, main circuit power supply
open-phase, insufficient main circuit power supply voltage).
When this parameter is set to 0.00, the above momentary
power outage is not detected.
FA-03
Overspeed error
detection level
0 to 150
(%)
[110]
When the detected speed value becomes abnormally high
compared to the maximum speed, an alarm trips as an
overspeed error. This parameter specifies the threshold
level for detecting the overspeed error as a percentage of
the maximum rotational speed of the robot.
When set to 0, overspeed errors are not detected.
FA-04
Speed error
detection value
0 to maximum
speed
*1
RDX (min
-1
)
RDP (mm/s)
[Depends on model]
When the speed error (difference between speed command
value and speed detection value) becomes abnormally
large, an alarm trips as a speed error.
This parameter specifies the threshold value for detecting
the speed error. When set to 0, speed errors are not
detected.
FA-05
Position error
detection value
0.0 to 100.0
(rotations)
[20.0]
When the position error (difference between position
command value and position detection value) becomes
abnormally large, an alarm trips as a position deviation
error.
This parameter specifies the threshold value for detecting
the position error in rotation units. When set to 0.0, no
position deviation errors are detected.
FA-07
DC bus power
supply
L123
Pn
[L123]
This parameter sets the method for supplying the main
power.
When this parameter is set to "Pn", momentary power
outage is not detected. Set this parameter to "L123".
Setting Method for supplying main power
L123
Supply 3-phase AC power as the main power
from terminals L1, L2 and L3.
*1: This is the maximum speed of the robot. Check the robot specifications.
