YASKAWA Power Regenerative Unit R1000 Series

(2) Regular maintenance (by cycle)

Maintenance project cycle operation requirements

Check the blade wear of the cooling fan after running for 20000 hours or 10 years, replace it with a fan of the same model, and reset the parameter o4-03

Measure the capacitance of the main circuit capacitor after 5-7 years of operation. If it is lower than 80% of the initial value, it needs to be replaced. Monitor the lifespan through U4-05

Check the torque of the main and control circuit terminals every 6 months to prevent looseness and heating during terminal tightening

Clean the radiator with compressed air every 3 months after power failure to avoid clogging the air duct

3. Maintain monitoring function

Parameters U4 series: U4-03 (fan running time), U4-04 (fan life percentage), U4-05 (capacitor life percentage), U4-06 (soft charging relay life). If it is less than 20%, it needs to be replaced in advance.

Peripheral equipment and communication configuration

1. Standard configuration and peripheral equipment

Required equipment: power coordination reactor, current suppression reactor, fuse (model needs to be matched according to the model);

Optional devices: 24V power supply (PS-A10LB/HB), USB replication unit (JVOP-181), LED operator (JVOP-182), communication tab (MECHATROLINK-II, CC Link, etc.).

2. MEMOBU/Modbus communication configuration

Communication parameters:

H5-01 (slave address): 0~FFH, default 1FH, ensure unique address;

H5-02 (baud rate): 0 (1200bps)~8 (115200bps), default 3 (9600bps);

H5-03 (checksum): 0 (no checksum), 1 (even checksum), 2 (odd checksum), default 0.

Communication function: Supports reading monitoring data, writing parameters, controlling operation/stop, fault reset, and can be remotely controlled through PLC or upper computer.
