Servo MKS HV6120
Super high torque/high speed programmable digital micro servo with titanium gears with twin ballraced output shaft. The high precision no-backlash pre-loaded gears and slim 8 mm servo case makes it particularly suitable for controlling ailerons and flaps in F3K hand launch gliders, light gliders (F5J etc.) and motor models with thin wing profiles. An aluminium case with flat mounting lugs for perfect cooling even under high loads.
Wide input voltage range 3.7-7.4 V (nominal), operational 3.5-8.4 V.
Using the DSP-1 USB Digital Servo Programmer/interface and the MKS PC software you can program a wide range of servo parameters:
Dead Band: The signal value can be allowed to change under the circumstance without affecting the angle of the output / servo arm. MKS Default = 1μs or 1.2μs
Lock: The setting when the servo does not receive the signal - Keep at the last angular position / The motor is released.
Max. Duty: The duty cycle of the motor will be limited within this value.
Pulse Lower: The minimum angular range will be limited within this command value.
Neutral: The setting of the neutral position.
Pulse Upper: The maximum angular range will be limited within this command value.
Boost: The steps of the motor when starting-up. The larger the value is, the more powerful the step of the motor during the start-up.
Left Angle: Max. Left angle adjustment.
Right Angle: Max. Right angle adjustment.
Reversion: Reverse of the PWM command.
Allow Uncont: The Servo move to the “Uncontrolled Position” when the PWM command is loss.
Uncontrolled Pos: The emergency position in the case of PWM command loss, if the “Allow Uncont” is turned on.
Uncontrolled Time: The Servo will move to the “Uncontrolled Pos” after the “Uncontrolled Time” when the PWM command is loss.
