1.3.1. Adjustment of Power System

 

In case of power system errors or power change, take a measurement of each power voltage, and adjust any voltage below the standard (use a digital voltmeter for measurement).

 

Table 1‑7 power standard value

Power	Measuring Location	Standard	Adjustment
Primary Power	CB1 input terminal	AC220V ± 10%	The first tap of the transformer TR1 is defined as AC220V
R6,S6,T6	Servo AMOP R, S, T	AC220V ± 10%	Check the CB1 input voltage (AC220V).
B2-C2	TB1 B2-C2	AC220V ± 10%	Transformer TR1 second tap change
P1-M1	SR1  +24V-G2	DC24V ± 2.0V	(Note 1)
P5-M0	SR1  +5V-G1	DC5.1V ± 0.1V	SR1 volume resistivity
P15-M0	SR1  +15V-G1	DC15V ± 0.5V	(Note 1)
N15-M0	SR1  -15V-G1	DC-15V ± 0.5V	(Note 1)
P5E-M5E	SR1  +5V-GND	DC5.4V ± 0.1V	SR1 volume resistivity (Note 2)
	Robot external wiring terminal and connector pins P5E-M5E	DC5.1V ± 0.1V	SR1 volume resistivity (Note 2)

 

(Note 1) Replace the SR1 if it is not within the standard.

(Note 2) First, check the standard in the measuring location, and then make a measurement in the nearest terminal stand from robot encoder and between connector Pins. Here, the standard must be DC5.1V±0.1V.
