Thank you for purchasing an MC601C . The MC601C is a high-frequency drive FET speed control developed for model
electric cars. It is compact and light weight competition speed control, and uses a simple digital setting system.
Applicable motors .UMBEROFTURNSISCRITERIA
Use the MC601C with a motor with 9 turns or more.
*If a motor with a number of turns smaller than the
above is used, the heat protector and overcurrent
protection circuit may operate. The number of turns of
the motor is a criteria only. Depending on the running
conditions, the protection circuit may operate even if
the condition above is satisfied.
*The internal circuit of MC601C is OK up to 9-turn
motors. On the other hand, the connectors for battery
and motor are general type that is often found at the
dealers. Therefore, to use high output power motor or
apply heavy load may result in overheating of the
connector section and melting the connection. If this
happen the connection will stick together. Please pay
special attention to avoid this matter.

INSTALLATION TIPS
s-OUNTTHESPEEDCONTROLINTHEMODELUSINGTHEDOUBLESIDEDFOAMTAPESUPPLIED
sProvide plenty of cooling openings in the bodywork; this increases the performance and extends the life of all
lectronic components.
s)NSTALLTHESPEEDCONTROLINALOCATIONWHEREITISPROTECTEDFROMCRASHDAMAGE
sThe speed control should be installed in such a way that you have easy access to all connectors and the set-up button.
Important:
s%NSURE that there is an adequate distance (approx. 3 cm) between the speed control and power cables and the receiver or receiver antenna. Avoid
direct contact between all power system components and the receiver or antenna, as this can cause interference. If you encounter interference
problems, re-position the components in the model.
s4HE antenna should be run vertically up and away from the receiver. Avoid contact with any parts made of carbon fibre or metal. See also the
instructions supplied with your radio control system.

POWER CAPACITORS
Power Capacitor stores battery energy and supplies this
to the motor additionally when extra power is required.
[Reference]
The MC601C has excellent acceleration and throttle
follow-up, but use this power capacitor when the course
to be run requires more than maximum power. However,
on a small technical course, not using the power
capacitor may also be effective.
[INSTALLATION]
See the pictures for the example of installation.
1Remove the terminal cover from the MC601C.
2 Use the included heat shrink tube to isolate the pins of the
Power Capacitor. This will also make it easier to indicate the
polarity of the Power Capacitor. Place the red heat shrink
tube on the positive terminal and the black heat shrink tube
on the negative terminal.
3 The Power Capacitor needs to be soldered to the speed
control between + (positive = M.B.+ ) and - (negative =
BAT.-).
4 Attach the terminal cover to the MC601C.
Heat shrink tube
(positive = red / negative = black)
Never reverse the capacitor,schottky diode and wires
polarity.
The capacitor may break or the capacitor electrolyte may leak.
The schottky diode breaks.
Reverse connection will immediately destroy the amp.
Never use solder containing acid flux.
Use solder containing rosin flux only. Do not inhale the solder
vapours. This might damage health.
Vibrationproof the capacitor by mounting it with thick
double sided tape.
If the pin of the capacitor is broken, it may short-circuit with the pin
between + and - terminal of the speed control.
Be careful when soldering to the tags on the speed
control; don’t overheat the tags with your soldering iron
and take great care to avoid short-circuits between two of
the three tags on the speed control.
Such a short-circuit would destroy the speed control.
In set-up mode MC601C stores every step when you press the Set-up button. All the settings are stored in the unit even when the
speed control is subsequently disconnected from the battery. Set up the following basic functions on your transmitter (if present):
s(IGH ATV, EPA (throttle travel) - maximum Low ATV, EPA, ATL (brake travel) - maximum
s%8P%80/exponential) - start with 0
s35"TRIMNEUTRALTRIMCENTER TH trim - center
sThrottle reverse (servo reverse) - any setting; must not be changed after completion of set-up procedure.
sAsymmetrical stick travel is possible (2/3 throttle - 1/3 brake)
If your transmitter does not feature these set-up functions, it is already in “basic set-up” mode.
Remove the motor pinion, or ensure in some other way that the wheels of the model are free to rotate.

Depending on the neutral position of the throttle stick, the red and green LED will blink simultaneously (orange) and a beeping
sound will be repeated. (Alarm: Waiting for neutral data)
Turn on the power in following order.
sThe SET LED flashes green, to indicate that the unit is in set-up mode.
sThis completes the set-up procedure.
Hold the SET button pressed in for at least 3 seconds using the small screwdriver supplied.

Protection Circuits
Heat protection: After FET overheating is detected, the output to the motor is gradually lowered and when 125 degress is reached,
a protection circuit operation alarm is activated and output to the motor is cut. The protection circuit is automatically reset by a drop in
the FET temperature.
Low battery protection: When the power supply voltage drops, the output current to the motor is limited and supply voltage to the
receiver is ensured. When the power supply voltage drops to the set voltage (initial setting 3.0V), a protection circuit operation alarm
is activated and output to the motor is cut. The protection circuit is automatically reset by recovery of the power supply voltage.
Terminal
cover
Motors with no suppressor capacitors, or
inadequate suppression, may cause the
MC601C to malfunction. Always solder the
capacitors supplied to your motor.
The schottky diode improves the efficiency of
the speed control / motor combination and
provides extra protection to the brake FETs.
The white ring must always face the positive
side. Schottky diode
Suppressor capacitors
Solder the suppressor capacitors and the
Schottky diode to the motor.
