6. Daily Maintenance and Periodic Inspection and Maintenance 

6.1  Maintenance Tools 

 

 

 

III-37

 

 

 

The following measuring instruments are used to confirm that the voltage is being supplied correctly to the 
NC unit, to confirm that the wiring to the NC unit is correct, and to carry out simple troubleshooting. 

Tester 

 

To check that the wiring to the NC unit is correct 
before turning the power ON. 

AC voltmeter 

Measure the AC power voltage.  
The tolerable error is 

±2%  

or less. 

To measures the AC power voltage being 
supplied to the external 24VDC power supply 
unit. 

DC voltmeter  Max. scale 30V.  

The tolerable error is 

±2%  

or less. 

To measure the DC power voltage. 

External power supply 24V (control section, 
machine input/output interface) 
Battery voltage  
HR081/HR082/HR083 DC output 

Phase rotation 
meter 

 

To check the connection order of the AC 3-phase 
input power supply. 

Oscilloscope 

 

General measurement and simple 
troubleshooting 

(Note 1)  Currently, a high-accuracy digital multi-meter is commonly used as a tester. This digital 

multi-meter can be used as both an AC voltmeter and an DC voltmeter. 

(Note 2)  A logic analyzer (sampling cycle 200MHz or more) is required for complicated troubleshooting. 

 

   Screwdriver (large, medium, small) 
   Radio pliers 

 
6.2  Maintenance Items 

 
Maintenance is categorized into daily maintenance items (items to be carried at set intervals) and periodic 
maintenance items (replacement of parts when life is reached).  
Some parts will not function in a hardware manner when the life is reached, so these should be replaced 
before the life is reached.
