Dead band
The dead band angle at stopping can be specified.
[Relationship between dead band set value and servo operation]
Small - Dead band angle is small and a small signal change immediately operates the servo.
Large - Dead band angle is large, and the servo does not operate at small signal changes.
(Note) If the dead band angle is too small, the servo will work continuously, and the current consumption will increase, and the life of the servo will be shortened.
Damper
The characteristic when the servo is stopped can be set. When smaller than the standard value, the characteristic becomes an overshoot characteristic. If the value is larger than the standard value, the brake is applied before the stop position. Especially when a large load is applied, overshoot, etc. are suppressed by inertia and hunting may occur, depending on the conditions. If hunting (phenomena which causes the servo to oscillate) occurs even though the Dead Band, Stretcher, Boost, and other parameters are suitable, adjust this parameter to a value larger than the initial value.
[Relationship between damper set value and servo operation]
Small - When you want to overshoot. Fixed so that hunting does not occur.
Large - When you want to operate so that braking is not applied. However, it will feel like the servo response has worsened.
(Note) If used in the hunting state, not only will the current consumption increase, but the life of the servo will also be shortened.
Smoother
This function makes the servo operation smooth. Set it according to your taste. Normally set it to "ACT". Set it to "INH when you want an exceptionally quick operation. When the smoother function was set to "ACT" and the servo has operated the distance up to the target position is changed in steps so movement is smooth.
Stretcher
The servo hold characteristic can be set. The torque which attempts to return the servo to the target position when the current servo position has deviated from the target position can be adjusted. This is used when stopping hunting, etc., but the holding characteristic changes as shown below.
[Relationship between stretcher and servo operation]
Small - Servo holding force becomes weaker.
Large - Servo holding force becomes stronger.
(Note) When this parameter is large, the current consumption increases.
Boost/Boost (ON/OFF)
INH: Boost is ON at the time of low-speed operation. (Normal)
ACT: Boost is always ON. (For quick operation).
The minimum current applied to the internal motor when starting the servo can be set. Since a small travel does not start the motor, it essentially feels like the dead band was expanded. The motor can be immediately started by adjusting the minimum current, which can start the motor.
[Relationship between boost set value and servo operation]
Small - Motor reacts to a minute current, and operation becomes smooth.
Large - Initial response improves and output torque increases. However, if the torque is too large, the operation will become rough.
Channel
This is the S.BUS system channel assigned to the servo. When connected to the receiver S.BUS2 connector as an S.BUS system, the channel used by the transmitter is assigned. When the normal receiver channel is used, the channel setting is unnecessary.
Reverse - The direction in which the servo rotates can be changed.
Soft Start - Restricts operation in the specified direction the instant the power is turned on. By using this setting, the first initial movement when the lower is turned on slowly moves the servo to the specified position.
Neutral - The neutral position can be changed. When the neutral offset is a large value, the servo’s range of travel is restricted on one side.
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.
Speed
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 exceed what the servo is capable of even if the servos operating voltage is increased.
Travel [Left]/[Right]
The maximum left and right travel centered about the neutral position can be set independently.
