Core Overview
This document is the installation manual for the Yaskawa U1000 series 24V power supply option (model PS-U10L/PS-U10H), which mainly introduces the functions, driver adaptation, installation process, operation verification, and safety specifications of the option. It provides users with full process guidance from receiving inspection to after-sales support, and is suitable for professional installation and maintenance personnel.
Core parameters and adaptation range of options
1. Option model and function definition
Model identification: This option includes two models - PS-U10L and PS-U10H, with the name "24V Power Supply" clearly indicating its core function: to provide a separate 24V DC power supply for the control circuit when there is no power supply for the main circuit of the drive, only supporting power supply for the control circuit, and unable to supply power to the main circuit of the drive 🔶 2-5 🔶 2-8 🔶 2-89.
Core purpose: With this option, users can access network communication, navigate digital operators, read I/O data, and view fault/parameter data while the main power is disconnected; If parameters need to be modified, the driver parameter o2-19 (UV state parameter writing selection) must be set to "1 (enabled)", otherwise the parameters cannot be modified even if the control circuit is powered on 🔶 2-91.
2. Adapt to the driver model and software version
According to document table 1 (Compatible Drive Models), the compatibility relationship between options and drives is as follows:
Option Model Adaptation Driver Series Driver Model Identification (Key Characters) Remarks
PS-U10L U1000, U1000L, Z1000U models containing "2" (such as CIMR-U 2 , CIMR-Z 2 ) require the driver software version to meet the standard
PS-U10H U1000, U1000L, Z1000U models containing "4" (such as CIMR-U , CIMR-Z 4 ) require the driver software version to meet the standard
The specific software version requirements are: U1000 series requires S5171, S1017 and above; U1000 crane specific models require S6412 and above; U1000L series requires S6213 and above. If the driver version is not met, it may cause the option to not work properly 🔶 2-96.
3. Key specifications and certification of options
On page 42 of the document (Table 4 Option Specifications), specify the technical parameters of the options and indicate the safety certification standards they comply with:
Electrical parameters: Input working voltage 24Vdc ± 20% (range 19.2V-28.8V), input current 1.9A, power consumption 38W, output holding time exceeding 50ms after power failure;
Environmental parameters: Operating temperature -10 ℃~+50 ℃ (14 ℉~122 ℉), short-term transportation and storage temperature -20 ℃~+60 ℃ (-4 ℉~140 ℃), weight 0.2kg (0.4lbs.), installation environment needs to match the specifications of the drive environment 🔶 2-431;
Certification standards: Compliant with UL (USA/Canada) and CE (Europe) certifications, with UL certification based on UL508C standard and CE certification in accordance with the Low Voltage Directive (2006/95/EC) and EMC Directive (2004/108/EC), following harmonized standards such as IEC/EN 61800-5-1 and EN 61800-3 🔶 2-431 🔶 2-499.

Detailed explanation of the entire installation process (including preparation, steps, and requirements)
1. Receipt inspection and installation preparation
(1) Receiving inspection items
After receiving the option, the user needs to complete three core checks: 1 Check if the appearance of the option is damaged during transportation. If damaged, immediately contact the transportation company (Yaskawa warranty does not include transportation damage); 2. Check if the option model is consistent with the order (refer to Figure 3 in the document for the location of the model identification); 3. Confirm that the packaging contents are complete, and the specific list is as follows 🔶 2-103 🔶 2-104 🔶 2-105,:
Item name, quantity, and purpose
Signal/power transmission between one option connecting cable and the driver
M3 screws with 3 options for fixation (some installation methods require the use of screws)
The installation method of the six parts of the stud (such as C, D, E, F) includes option fixing
6 zip ties for organizing cables to avoid clutter or pressure
Installation Manual (TOBPC73060095. pdf) 2 copies of technical guidance (including both Chinese and English versions)
Option body (PS-U10L/PS-U10H) 1 core functional component
If you receive an incorrect model or option that does not work properly, you need to contact the supplier for assistance.
(2) Essential Tool List
The document clearly lists the required tools and specifications for installation. Missing or using non compliant tools may result in installation failures:
Cross screwdriver: M4 metric specification, or # 1, # 2 American standard specification, used for disassembling/installing drive cover screws;
