ESC Link Function "MC LNK"

MIn" which sets the frequency when the load is small, is set to the high frequency side (large value) when extension is desired after straight-

aways and curves.
"

MAX" which sets the frequency when the load is large, is set to the high frequency side (large value) when you want to suppress the rise

from low speed and when motor heating and commutator roughness are sensed.
When the rise from low speed is poor, and becomes bad even when "

MAX" is set to the low frequency side, use the log data to check if there

was a momentary voltage drop. When you want to suppress the overall power, lengthen the run time, and otherwise improve efficiency, set

both "

MAX" and "MIn" to the high frequency side. When you want to set a fixed PWM frequency at full range regardless of the load current,

set PWM frequency (at Max. load) and PWM frequency (at Min. load) to the same value.

LBP-(LOW BATTERY VOLT) 2.5V~7.5V
Same as Link software Low Bat Protection
This setting cuts off the output to the motor when the main battery voltage drops to the set voltage. This stops
the receiver ceasing operation when the power to the receiver becomes insufficient whilst running due to a
drop in the power supply voltage. When the power supply voltage recovers, power is supplied to the motor
once more.

REV-(REV CANCEL) BRk /REV
Same as Link software Reverse Cancel.
When set to BRk, reverse operation is disabled.

DBA-(DEAD BAND) ±2μs~±50μs
Same as Link software Dead Band.
This sets the range (neutral point range) over which the
ESC does not respond to transmitter throttle operation.
The larger the set value, the wider this range.

BMD-(BRAKE MAX DUTY) 0%~100%
Same as Link software Brake Max. Duty.
This setting can set the braking force between the neutral point and Max
brake point. The larger this value, the greater the braking force. When set
to "0%", the brakes are disabled.
RMD-(REVERSE MAX DUTY) w/back only 0%~100%
Same as Link software Reverse Max. Duty
This setting can set the reverse power between the neutral point and Max
reverse point. The larger this value, the greater the reverse power. When
set to "0%", reverse is disabled.

BKS-(BRAKE SLOPE) 0~300 (Only when used TBM-LEV2)
Same as Link software Brake Slope.
This function adjusts the braking effect when the throttle is
returned (throttle off). It eliminates the effect known as “en-
gine braking” in full sized vehicles.

BEC-(BEC VOLT) 6.0V / 7.4V
Same as Link software BEC Volt.
The receiver BEC voltage can be selected from 6.0V and
7.4V. Match the voltage to the rating of the servo connect-
ed to the same receiver. This BEC voltage cannot output a
voltage higher than the input voltage.
