Parameter name
Setting range
[Default value]
Description
Fb-16
Forward position
limit value
(H/L)
±0 to ±19999
*2
(pulses)
[0]
Sets the drive range in the forward (+) direction.
Ten-digit data (number of position sensor pulses)
consisting of high-order digits specified by Fb-16
and lower-order digits specified by Fb-17 is used to
determine the forward (+) position limit value. No
limit is in effect when these parameters are set to 0.
Note: Refer to precautions on Fb-18 and Fb-19.
Fb-17
0 to 99999
(pulses)
[0]
Fb-18
Reverse position
limit value
(H/L)
±0 to ±19999
*2
(pulses)
[0]
Sets the drive range in the reverse (–) direction. No
limit is in effect when these parameters are set to 0.
Note: In the following case, the setting is invalid and
the motor operates with no limit.
Position limit value (+)
≤
Position limit value (–)
(Fb-16: Fb-17) (Fb-18: Fb-19)
Fb-19
0 to 99999
(pulses)
[0]
Fb-20
Forward speed
limit value
0 to maximum
speed
*1
RDX (min
-1
)
RDP (mm/s)
[Depends on model]
Sets the upper speed limit.
Fb-21
Reverse speed
limit value
-maximum speed

)
RDP (mm/s)
[Depends on model]
Fb-23
Positioning
detection range
1 to 65535
(pulses)
[20]
Sets the threshold value for position deviation
(difference between position command value and
position detection value) used to determine whether
positioning is complete.
Fb-24
Positioning
interval time limit
0.00 to 10.00
(s)
[0.00]
Sets the threshold value for the time difference
between position command value and position
detection value (time required for position detection
value to reach the position command value) used to
determine whether positioning is complete.
When set to 0.00, no monitoring is performed. This
parameter can be set in 0.02 steps.
Fb-25
Up to speed
detection range
0 to 100
RDX (min
-1
)
RDP (mm/s)
[10]
Sets the threshold value for the speed deviation
(difference between speed command value and
speed detection value) used to determine whether
the specified speed is reached.
Fb-30 S-curve ratio
non
SHArP
rEGLr
LooSE
[non]
Set this parameter to "non".
Fb-35
Homing back
distance
1 to 255
[Depends on model]
Sets the distance the robot moves back from the
mechanical end after detecting it during return-to-
origin operation using the stroke end method.
*1: This is the maximum speed of the robot. Check the robot specifications.
*2: Methods for displaying and entering these parameter values (–10000 to –19999) differ from other
methods. For the operation method, refer to "(3) Special display" in section 6.1.2, "Operating the digital
operator".
