Description of the function of each parameter
• Neutral Offset
The neutral position can be changed.
• Speed Control
Speeds can be matched by specifying the operating speed. The speed of multiple
servos can be matched without being affected by motor fluctuations. This is effective
for load torques below the maximum torque.
However, note that the maximum speed will not be exceeded even if a speed over the
maximum speed of the servo at each operating voltage is set.
• Dead Band
The dead band angle at stopping can be specified. If the dead band angle is small,
the servo will operate continuously and the life of the servo may be shortened.
• Travel Adjust
The left and right travels centered about the neutral position can be set independently.
• Anti-Fluttering Level
With fuselages with a large wing area, etc., the flutter phenomena whereby the
control surfaces begin to oscillate continuously due to inertia may occur. However,
when this phenomena occurs, the oscillations can be reduced by changing this
parameter. Mode 5 has the highest suppression effect.
• Reverse
The direction in which the servo rotates can be changed.
• Servo Type
When the servo remains stopped for 30 seconds, the dead band expands and
unnecessary hold current due to external force is eliminated. When a new position
signal enters, the normal mode is restored and normal operation is resumed.
Select the "Retractable" mode for the retractable landing gear servo. In this case, set
the Travel Adjust and the Speed Control at the same time.
• Soft Start
Restricts operation in the specified direction the instant the power is turned on. By
making this setting, only the first operation when the power is turned on slowly moves
the servo to the specified position.
• Stop Mode
The state of the servo when the servo input signal is lost can be specified. The "Hold" mode
setting holds the servo in its last commanded position even if using AM or FM system.
• Smoother
This function smoothly changes servo operation relative to operation signal changes.
Normally use at Smooth setting. Especially, select the "OFF" mode when quick
operation is necessary.
