( 4 ) Reference Unit Selection
Description
Bit 9
Simple ABS Rotary Pos. Mode
Set whether or not the infinite length position control function is used, on the condition that the number of turns
that the encoder can count is a multiple of the number of turns corresponding to the reference unit reset fre-
quency.
With this function, it is not necessary to save and load absolute infinite axis information, eliminating the need
for a ladder program and thus simplifying handling. It is recommended that the Simple ABS Rotary Pos. Mode
is set to Enabled for ABS infinite length axes.
0: Disabled (default)
1: Enabled
Refer to 9.4.2 ( 2 ) Machine Controller Fixed Parameters for Absolute Position Detection and
9.4.1 ( 2 ) Conditions to Enable the Simple Absolute Infinite Axis Position Control for details.
Set to 0 for linear type.
Bit A
User Constants Self-Writing Function
Set whether or not to use the function that automatically writes Machine Controller setting parameters to the
SERVOPACK parameters when a MECHATROLINK communication connection is established. Also, the auto-
matic writing is triggered by changing the setting parameters or starting execution of a motion command.
0: Enabled (default)
1: Disabled
Refer to 11.6 Parameters That Are Automatically Updated for details.
No. 2
Function Selection Flag 2 Setting Range Setting Unit Default Value
− − 0000H
Description
Bit 0
Communication Abnormality Detection Mask
Masks MECHATROLINK communication errors detected at the Machine Controller.
0: Disabled (default)
1: Enabled
Bit 1
WDT Abnormality Detection Mask
Masks MECHATROLINK watchdog timeout errors detected at the Machine Controller.
0: Disabled (default)
1: Enabled
No. 4
Reference Unit Selection Setting Range Setting Unit Default Value
0 to 4 − 0
Description
Set the unit for the reference.
The minimum reference unit is determined by this parameter and the Number of Digits Below Decimal Point setting
(fixed parameter No.5). If pulse is selected, the Electronic Gear Ratio (fixed parameters 8 and 9) will be disabled.
0: pulse (electronic gear disabled)
1: mm
2: deg
3: inch
4:
μm
Refer to 5.1.1 Reference Unit for details.
For linear type, 0 (pulse), 1 (mm), and 4 (
μm) can be used. If 2 (deg) or 3 (inch) is selected, the
selected unit will be converted to mm.
