Servo Parameter Area Section 4-5
0: Reversal mode 1
1: Reversal mode 2
2: Single-direction mode
3: Reversal mode 3 (unit version 2.0 or later)
Origin Detection Method (Unit Version 2.0 or Later)
Select the origin detection method. For details on operation patterns, refer to
8-2-4 Origin Search Operation .
0: With origin proximity input signal reversal
1: Without origin proximity input signal reversal
2: Not use origin proximity input signal
Origin Search Direction
This parameter sets the origin search direction to match the Zero Point Return
Direction setting (Pn816) in the Servo Parameters. This parameter and Servo
Parameter Pn816 must be set to the same value. For details on origin search
operations, refer to
8-2-4 Origin Search Operation .
0: Forward direction
1: Reverse direction
Origin Search Preset (Unit Version 2.0 or Later)
The present position can be automatically set to a preset value when the ori-
gin search has been completed normally. Refer to
8-2-6 Origin Search Preset
for details on the origin search preset.
0: Present position not set to preset value at completion of origin search
1: Present position set to preset value at completion of origin search
Encoder Type
Use this parameter to select incremental encoder or absolute encoder as the
encoder for the Servomotor. Set the encoder type according to the functions
of the Servomotor and Servo Drive being used, as follows.
0: Incremental encoder
1: Absolute encoder
Setting Example In this example, an incremental encoder is used with axis 5, and origin search
is set to reverse direction in single-direction mode.
18B1 hex: 1020 hex
18B2 hex: 0000 hex

4-5 Servo Parameter Area
4-5-1 G-series Servo Drive (R88D-GN
@
-ML2 with Built-in
MECHATROLINK-II Communications)
The Servo Parameters listed here can be used when the Position Control Unit
is used with a G-series Servo Drive (R88D-GN
@ -ML2) with built-in MECHA-
TROLINK-II communications.
For further details on each of the parameters, refer to the user’s manual for G-
series Servo Drives.
