7.1 Note on Setting Parameters
7.1
Note on Setting Parameters
Set the positioning parameters and servo parameters according to the system.
The following parameters must be set.
Axis selection of servo amplifier
The 20SSC-H controls the X- and Y-axis based on the order (smaller numbers given higher priority) of the
axis selection setting in the servo amplifier.
Therefore, set servo parameters corresponding to axis selection setting at servo amplifier.
If the axis selection setting at servo amplifiers are the same, external errors (error code: 4011) may occur in
the 20SSC-H.
Setting example
Caution on the use of the MR-J3W-
B
The 20SSC-H can connect and use the MR-J3W-
B within the functional range of the MR-J3-
B.
Therefore, set up servo parameters within the range of the servo parameters of the MR-J3-
B, and set them
according to the following points carefully.
→
For setting up servo parameters of the MR-J3W-
B, refer to the MR-J3W-
B Servo Amplifier
Instruction Manual
a) Parameters shared between two axes
Shared servo parameters between two axes should have the same setup for both axes (X-axis, Y-
axis) in servo parameters of the 20SSC-H.
If they are set up differently, the setting value of the last axis set up is set to both axes of the servo
amplifier.
b) Servo series setup of the 20SSC-H
The servo series of the 20SSC-H should set for both axes (X-axis, Y-axis) as "MR-J3-B."
c) When using the MR-J3W-
B using single axis setup
Even if using the MR-J3W-
B using single axis setup, the servo series of the 20SSC-H should set for
both axes as "MR-J3-B."
If not set in both axes, communication between the 20SSC-H and servo amplifier cannot be started.
Caution on the use of the MR-J3-
BS
The 20SSC-H does not support the fully closed loop system.
Therefore, set up servo parameters within the range of the semi closed loop system.

For setting up servo parameters of the MR-J3-
BS, refer to the MR-J3-
B Safety Servo Amplifier
Instruction Manual
1) Servo series [Servo parameters (Basic setting)]
This parameter must be set to transfer information between the 20SSC-H and servo amplifier.
Set the servo series of servo parameters according to the servo amplifier.
→
For servo series details, refer to Subsection 11.2.1
2) Function selection C-4 [Servo parameters (Expansion setting)]
Immediately after power ON, this parameter needs to be set to operate in modes other than the JOG or
manual pulse generator operation modes.
Set "1: Not needed to pass motor Z-phase after the power supply is switched on" (default setting) here.
In other setting cases, the servo motor should be rotated more than one revolution by the JOG or manual
pulse generator immediately after power-ON.
→
For details, refer to Subsection 8.1.2 to 8.1.5 and 11.2.3
3) Zero return interlock setting [Positioning parameters (Operation parameter 2)]
Immediately after power ON, this parameter needs to be set to operate in modes other than the JOG,
manual pulse generator or mechanical return operation modes.
Set "0: Disable" here.
In other setting cases, operate to be set to the zero return executed flag.
→
For details, refer to Subsection 7.9.10 and 11.1.2
