Okuma Alarm-D 4186 MCS Collision detected
The NC torque limiter has detected collision of axis by monitoring the relation between motor output torque and motor acceleration.
Axis name or none (spindle)
XXXX: Detected torque (sum of torque data collected for 3.2 ms)
If Tv = 0.4 ms, the momentary maximum torque is H’7FFF.
If Tv = 0.8 ms, the momentary maximum torque is H’3FFF.
YYYY: Detected acceleration (average torque measured for 3.2 ms)
= about 0.1 [1/min/ms]
Probable Faulty Locations
– Motor encoder
– NC torque limiter set value
