"min" which sets the frequency when the load is small, is set to the high frequency side (large
value) when extension is desired after straightaways 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.

MC Link Function (ESC Link)

PWM frequency (min)

MC401,402CR/601,602C/850,851C :0.1kHz(100Hz) 10kHz (10000Hz)
MC950CR :0.5kHz(500Hz) 30kHz(30000Hz)
MC940,960CR :1kHz(1000Hz) 30kHz(30000Hz)

Same as Link software PWM frequency (at Min. load),

MIn sets the "0"A PWM frequency at minimum load.

PWM frequency (max)

MC401,402CR/601,602C/850,851C:0.1kHz(100Hz) 10kHz (10000Hz)
MC950CR

:0.5kHz(500Hz) 30kHz(30000Hz)

MC940,960CR :1kHz(1000Hz) 30kHz(30000Hz)

Same as Link software PWM frequency (at Max. load).
MAX sets the PWM frequency at maximum load at the out-
put current limit value set by Current Limiter.

PWM frequency (brake)

MC402CR/602C/851C (MC401,601,850 cannot be adjusted 2kHz ﬁxation)
:Normal(2000Hz) /Hard(1000Hz) /Super hard(500Hz)
MC950CR :0.5kHz(500Hz)30kHz(30000Hz)
MC940,960CR :1kHz(1000Hz)30kHz(30000Hz)

Same as Link software Brake PWM at frequency.

This setting can set the brake PWM frequency.

Dead Band

All type :±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.

System function setup

Select the setting item by (JOG) button up, down, left, or right operation.

Set the value by (+) and (-) button.
