MIn-(PWM FREC MIN LD) 100Hz~10000Hz (10kHz)
MC950CR:500Hz~30000Hz (30kHz)
Same as Link software PWM frequency (at Min. load),
MIn sets the "0"A PWM frequency at minimum load.
MAX-(PWM FREC MAX LD) 100Hz~10000Hz (10kHz)
MC950CR:500Hz~30000Hz (30kHz)
Same as Link software PWM frequency (at Max. load).
MAX sets the PWM frequency at maximum load at the output cur-
rent limit value set by Current Limiter.
CLM-(CURRENT LIMIT) 50A~300A (MC950CR:50A~300A), OFF Same as Link software Current Limiter.
Current Limiter sets the current value at maximum load here.
Since setting of the MAX is based on the output current limit value set by Current Limiter, Current Limiter does not
have to be turned OFF except when a current exceeding 300A is generated.
BRK-(PWM FREC BRK LD) nOR(2000Hz)/ HIG(1000Hz)/ SPH(500Hz)
MC950CR:500Hz~30000Hz (30kHz)
Same as Link software Brake PWM at frequency.
This setting can set the brake PWM frequency.
"
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-
away 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.
nTB-(NEUTRAL BRAKE) 0%(OFF)~100%
Same as Link software Neutral Brake.
Use this setting when you want to use the brakes at the neutral throttle (OFF) position by throttle operation. The
larger this value, the greater the braking force. When you want to use the neutral brake, set this value to "0%".
