Low Bat Protection
MC401,402CR/601,602C/850,851C:2.5V 6.0V
MC950CR/MC940,960CR 2.5V 7.5V
Same as Link software Low Bat 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, a pro-
tection 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.
Current Limiter
MC401,402CR/601,602C/850:50A 300A, INH
MC851C :50A~300A(can not INH)
MC950CR/MC940,960CR:50A~500A, INH
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.
Current limiter INH/ACT setting
With the MC950CR and MC940/960CR move the cursor to current limiter "INH(Off)/ACT(On)" and select INH or
ACT with the (+) or (-) button.
With other MC, when the (+) button is pressed from the current limiter maximum value, INH(Off) is set.
The MC851C does not have an INH(Off) setting.
Current Limit timer
MC401,402CR/601,602C/850,851C:0sec(OFF)240sec
MC940,960CR:0sec(OFF)~240sec (MC950CR can not)
Same as Link software Current Limit timer.
The output current can be limited up to the set time lapse from the start of running. This is effective in preventing
the motor from outputting wasted energy when the voltage is high immediately after the power battery was re-
charged.
"Current Limiter (time)" sets the time the output current is limited. This function is disabled when set to "0" sec.
Since the Current Limit Timer starts when the throttle is operated to the forward side and current is output to the mo-
tor, this function begins to operate when the motor is run during trim adjustment, etc.
Current Limiter (time)
MC401,402CR/601,602C/850,851C :50A~300A
MC940,960CR :50A~500A (MC950CR can not)
"Current Limit timer " (Time Limit) sets the maximum output current within the time the output current is limited.
