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 1‑19 Controller power standard value (Hi5a-S)

Power	Measuring Location	Standard	Adjustment
3-phase power	CNT2 input terminal	AC220V ± 10%	Input voltage tab of transformer TR2
B2-C2	CNFN1 B2-C2	AC220V ± 10%	Input voltage tab of transformer TR2
B3-C3	CN220 B3-C3	AC220V ± 10%	Input voltage tab of transformer TR2
P1-M1	SR1  P1-M1	DC24V ± 2.0V	(Note 1)
P5-M5	SR1  P5-M5	DC5.1V ± 0.1V	SR1 volume resistivity
P5E-M5E	BD544 EC2 both ends	DC5.4V ± 0.1V	BD544 volume resistivity VR1
	Robot external wiring terminal and connector pins P5E-M5E	DC5.1V ± 0.1V	BD544 volume resistivity VR1 (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.
