5.2.2 Axis Parameters (Basic Setup)
Basic Setup
Comment Blank
Arbitrary comments can be input. Comments can be stored in
FP7 MC Unit since Ver.1.2.
Positioning repeat
count
UM 009F0
0
The number of repetitions of positioning control is set.
Range: 0 to 255 times
Repeat count: When it is 0 or 1, the positioning operation is not
repeated.
Repeat count: In the case of 255, operation is repeated
Unit setting
UM 03240
P: pulse
The units for specifying position command values and speed
command values are set.
P: pulse
M: μm [Min 0.1], M: μm [Min 1]
I: inch [Min 0.00001 inches], I: inch [Min 0.0001 inches ]
D: degree [Min 0.1], D: degree [Min 1]
Number of pulses per
revolution
UM 03242-UM 03243
1
Only when the unit is set to um, inch, or degree, the pulse
number and movement amount per revolution are set.
The ranges vary depending on the unit settings as below.
µm: 1 μm
inch: 1/10,000 inch
degree: 1 degree
Movement per
revolution
UM 03244-UM 03245
1
CW/CCW direction
setting
UM 03254 bit1
0: CW direction +
0: CW direction +: Set the direction that an elapsed value is + as
CW.
1: CCW direction +: Set the direction that an elapsed value is +
Limit switch
UM 03254 bit0
N: Disabled
When using the limit switch function or the home return function
using limit switches, select “A: Enabled”.
Limit switch
connection
UM 03254 bit2
S: Standard
When the arrangement of the connected "limit +" and "limit -" is
opposite to the input state loaded to FP7 MC Unit, select "R:
Reverse connection".
S: Standard, R: Reverse connection
Limit + Switch logic
UM 03254 bit4
1: Normal Close
(B contact)
Select the input logic of the limit switches.
0: Normal Open (A contact), 1: Normal Close (B contact)
Limit - Switch logic
UM 03254 bit5
(Note): The values set in these parameters are stored in the unit memory numbers described below the parameter
names.
• In FP7 MC Unit, CW refers to the rotating direction with a count increase
and CCW refers to the direction with a count decrease. Therefore, limit input
in the CW direction is limit + input and that in the CCW direction is limit -.
• In the system using FP7 MC Unit, limit switches are connected to the
general-purpose inputs (SI-MON3 and SI-MON4) of Servo Amplifier A6B/A5B.
When the "Limit switch" is set to "Enabled" in the above parameter, the
state of the general-purpose inputs (SI-MON3 and SI-MON4) of Servo
Amplifier A6B/A5B is reflected as the limit inputs of FP7 MC Unit.
• It is recommended to select "Normal Open (A contact)" for "Limit + Switch
logic" and "Limit - Switch logic". The input logic selected on the Servo
Amplifier A6B/A5B side is reflected as is.
