(3) Stains and smudges
Check the motor surface and bolt holes for oil or
cutting fluid. Oil or cutting fluid can damage the
coating by chemical reaction, possibly leading to a
failure. Therefore, wipe off oil and cutting fluid on the
motor surface periodically.
If the motor contains a large quantitius of oil or cutting
fluid, check how such a liquid leaks onto the motor, and
how the motor is protected from oil or cutting fluid
(covering the motor and so on)
(4) Insulation resistance
Check the insulation resistance between motor coil and
motor frame with insulation-resistance
tester(500VDC). Insulation level is following the below
table.
Value of
insulation
resistance
Judgement
100M Ω or more
Good.
10 to 100M Ω
Caution. Check the insulation level at every morning, or
replace the motor.
1 to 10M Ω
Warning. Check the insulation level at every morning, or
replace the motor.
less than 1M Ω
No good. Replace the motor.
(5) Observation of torque command (TCMD) and velocity
command (VCMD) waveforms
Observe the normal voltage waveforms with an
oscilloscope, and keep notes of them. During periodic
inspection, check the current waveforms with the
records.
The waveforms vary according to the operating
conditions such as load and cutting speed.
Note that you should make comparisons under the
same condition (during fast traverse to the reference
position, low-speed cutting and so on).
See descriptions on the servo check board in Chapter I-
5 for detailed inspection procedures.
