(000) Rotation Direction
Switching 2 Set the relation between the command direction and
the motor rotation direction.
0: With a forward rotation command, the motor rotates
CW as viewed from the axis end.
1: With a forward rotation command, the motor rotates
CCW as viewed from the axis end.
1 - 0 to 1 C

(001) Control Mode Selec-
tion 2 Select the Servo Drive CONTROL mode.
0 to 5: Switch function
6: Full closing control 0 - 0 to 6 R
002
(002) Realtime Autotuning
Mode Selection 2 Set the OPERATION mode for realtime autotuning.
0: Disabled
1: Emphasizes stability
2: Emphasizes positioning
3: If there is an unbalanced load on the vertical axis or
the like.
4: When friction is large.
5: If there is an unbalanced load on the vertical axis or
the like and friction is too large.
6: When the realtime autotuning is customized.

Machine Rigidity Set-
ting 2 Set the machine rigidity for executing realtime autotun-
ing.
11/13

004
(004) Inertia Ratio 2 Set the load inertia as a percentage of the motor rotor
inertia. 250 % 0 to 10000 B
009
(009) Electronic Gear
Ratio Numerator 4 Set the electronic gear ratio.
If Pn009 = 0, the encoder resolution is set as the
numerator.

(00D) No. 1 Torque Limit 2 Set the No. 1 limit value for the output torque of the
motor. 500 % 0 to 500 B
014
(00E) Error Counter Over-
flow Level 4 Set the range of the error counter overflow level. Detec-
tion of error counter overflow level error is disabled if
the set value is 0. 100000 Com-

(00F) Operation Switch
when Using Absolute
Encoder 2 Select the absolute encoder usage method.
0: Used as absolute encoder.
1: Used as an incremental encoder.
2: Used as absolute encoder.
(Multi-rotation counter overflows are ignored.)
1 - 0 to 2 C
016
(010) Regeneration Resis-
tor Selection 2 Select the Regeneration Resistor used.
0: Use the Built-in Resistor.
Triggering of regeneration overload protection
(Alarm No.18) depends on the Built-in Resistor (with
approx. 1% duty).
1: Use an External Resistor.
The regeneration processing circuit operates and
regeneration overload protection (Alarm No.18) is
triggered when the operating rate of the Regenera-
tion Resistor exceeds 10%.
2: Use an External Resistor.
Regeneration overload protection (Alarm No.18)
does not operate.
3: No Regeneration Resistor
All regeneration power is processed with built-in
capacitors.

(011) External Regenera-
tion Resistor Setting 2 Select the type of load ratio calculation for the External
Regeneration Resistor.
0: Regeneration load ratio is 100% when operating
rate of the External Regeneration Resistor is 10%.
1 to 4: Reserved
