INTRODUCTION

CAUTION : This is not a toy. This device is not intended for use by young children under 14 years of age or uninformed persons.
This document contains general servo information and frequently asked questions regarding the use and care of MKS servos. Please note that unauthorized modifying your servo will void the warranty. Since MKS nor the distributor KAVAN Europe s.r.o. has no control over the installation and use by the user, no responsibility can be implied in the case of improper or irresponsible use.
Before using your new servo, please read this manual thoroughly and use the servo properly and safely. After reading this manual, store it in a safe place.

WARNING

Turn on the power in transmitter first, only than the receiver. Always check the operation of all the servos before flight.
Do not leave the servo in the locked state. Leaving the servo in the locked state (state in which enough force is applied that the servo cannot move) may cause damage to the servo with a serious fire risk.
Do not connect the battery in reverse. Reverse connection may cause damage to the servo with a serious fire risk.
Do not expose the servo to dust and water. Unless explicitly stated otherwise, the servo does not have a waterproof construction. If it gets wet, the servo may not operate or the power supply may short circuit.
For the servo featuring all-metal case or mid-case aluminium heatsink: Install the servo so it does not touch metal parts of the model. It will generate a large amount of noise if touched. It will become impossible to receive and is extremely dangerous.
When installing the servo, check the pushrod linkage to make sure there is no binding in order to prevent excessive power consumption and decrease the life of the motor and battery.

CAUTION

Do not touch the servo case immediately after your model operation. You may be burned because the motor and circuits inside the servo become hot.
Do not turn the servo horn with unreasonable force. Do not try to turn the servo with your hand when under power. The servo may be damaged.
Do not disassemble or modify the servo. The servo has a precision construction. MKS and the distributor will not be responsible for any disassembly or modification other than specified by them.
Do not drop the servo or expose it to strong shocks or vibrations. It will damage with a shock.
Use the servo in model hobby applications only. MKS and the distributor will not be responsible if the servo is used in applications other than that.
MKS and the distributor will not be responsible for damage, etc. caused by the use of parts other than genuine MKS parts.

GENERAL INFORMATION

Current Consumption
This servo is designed to be used with models which require especially high torque and high speed. For this reason, a large current flows during servo ope-ration. Therefore, decide the safe number of uses by paying careful attention to the remaining battery capacity.

Power Supply

Use the battery or BEC stabilizers/voltage regulators according to the specification of your servo. Use a battery or voltage regulator with an ample margin as the power supply. The specified performance cannot be achieved with a dry cell battery.
Always check the battery voltage and charge the battery as needed.
When using 5 or more servos for large scale models, use a separate power supply.
High voltage servos (HV, HBL lines) require 6.0-7.4 V power supply (5-cell NiMH, 2S LiPo/Li-ion/LiFe). The specified performance cannot be achieved with a 4.8 rated power supply (4-cell NiMH).
Pay close attention to the input voltage range of the servo. NEVER use a power supply with voltage higher than 6.0 V for regular (4.8-6.0 V) voltage servos (DS line).
A power supply with voltage higher than 6.0 V (like 2S LiPo pack) may ONLY be used with high voltage MKS servos (HV and HBL lines).

Servo Arm
Please use an optional aluminium servo arm when you are operating large scale models (e.g. a model plane powered by 50 ccm or bigger petrol engine or a corresponding electric motor). The regular plastic arms are not enough for these applications.

RC Set
For full performance, 2.4GHz system is recommended.

Frame Rate

MKS digital servos employing the standard 1520 µs neutral signal pulse width can work with 50-333 Hz frame rate control signal (20 ms to 3 ms period).
Digital narrow-band servos employing 760 µs neutral signal pulse width can work with frame rate control signal up to 560 Hz (1.8 ms period).

Servo Connector
MKS servos use the standard JR/UNI servo connector.

PROGRAMMING

Except for the servos not designed as programmable listed below, the MKS servos can be programmed using the DSP-1 programmer and MKS PC software.

Standard Functions

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. Note: Too large value may cause the servo jittering.

Advanced Functions

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. You will find the detailed information on programming in the DSP-1 digital servo programmer instruction manual.

THE APPROPRIATE SERVO FOR YOUR APPLICATION

One of the most frequently asked questions is: „What servo should I use for my model?“.
While there have been many magazine articles that attempted to provide a general rule of thumb to answer these questions, we offer you the following suggestions:

Servos are rated for Speed and Torque. These should be reasonably proportional to the weight and speed of your model and to control response require-ments.
If you are not sure, it is better to have more torque than you need, as torque is your friend.
When in doubt ask your peers about servo application questions. Look at what others are using in comparable applications. Usually the kit manufacturer will suggest a servo of a certain physical size and torque value specification in the aircraft, helicopter, car or boat plans/manuals. It is wise to follow their guidelines.
Even though micro servos may offer high torque, they are not appropriate for larger powered aircraft due to the flight loads placed on the control surfaces during flight. The gear train can fail under excessive flight loads. Smaller servos have thinner gears that are inherently more fragile than those of „standard“ sized servos.

SERVO MAINTENANCE

Changing Gears and Case
MKS offers gear and case sets for almost all servos and these are available from your local hobby shop or from a mail order retailer. To replace the gears on any servo, carefully lay out the new gears on a clean work surface to have them available for re-assembly. You will also need a supply of servo gear lubricant. Only use a lubricant expressly designated for servo gears.

Loosen or remove the screws located on the bottom of the servo case enough to pop the upper case off and expose the gears. If any gears or shafts are stuck in the upper case, remove them and plug them back into position on the lower case. Now carefully remove the gears while placing them in approximate order on your work surface in front of you.

This is done so you can refer back to their positioning as you assemble the new set into the lower servo case. Clean all the old lubricant from the servo case in both the lower and upper case components. Be aware of small chunks of gear material that may be lodged in the lubricant and get it all cleaned out. Apply servo gear lube to the shafts and assemble the gear train applying lube to all gear components. When complete, pop the case top back on and tighten up the case screws.

CAUTION : Do not force the case top back on. If it will not fit back on smoothly, chances are the gears were installed incorrectly.

SERVO TROUBLESHOOTING

Servo makes a grinding noise or acts erratic: Open the case and remove the gears. Examine them for broken teeth. If broken, replace with a new gear set.
Servo jitters: This may be a dirty potentiometer. Open the case and remove the gears. Spray a zero-residue tuner cleaner (isopropylacohol obtainable in hobby electronics shops) into and around the „pot“ and work it in. Do not use regular “electric contact cleaners“ – these might help for a moment, but their residues left inside might destroy the potentiometer rather quickly. Once the cleaner has dried, re-install the gears and close up the case.
Checking Servo Centring: Remove the servo from the plane or vehicle. With the arm still attached to the servo, place an ink dot towards the end of the wheel and another one on the case; these should be lined up for a reference point. Plug the servo into the receiver and move the corresponding transmitter stick or wheel from stop to stop. After each movement, check the reference points for alignment.
Servo is locked in place: Open the case and make sure the gears are properly aligned. Next check the case top for wear. If wear is evident, replace the case.
Servo hums under load: This can be normal; the servo is trying to hold position against the force of a load. If it hums when no load is applied, try loosen-ing the servo case screws a quarter to a half a turn. Note: Digital servos always “buzz” more or less – this is a normal sound due to the switching frequency of their electronics.
Servo gets hot: Check the servo wiring, it should match the receiver being used. The motor could be stalled due to a failed gear train. Actually several things could be wrong, this sounds like a candidate for the service department.
