ABB PFVL142R Vertical measurement sensor

SGDG-04GTY22P Connect the regen resistor between terminals B1-B2 on the SGDG-04GTY22P digital torque amplifier.For Digital Torque Amplifiers of 500W Capacity or More Open terminals B2-B3 on the digital torque amplifier (remove the wire), and connect the regen resistor between terminals B1-B2.The regen resistor reaches high temperatures. Use wires with high-temperature insulation, and make sure the wires do not come into contact with the regen resistor. When an external resistor is connected, turn OFF #5 of SW1. Be sure the energy capacity of the resistor is adequate to dissipate the regen energy of the load. ■ Calculating Regen Energy For the procedure to calculate regen resistor capacity, please refer to Chapter 5 of the Sigma II Series Servo System User’s Manual (Doc.# YEA-SIA-S800-32.2x).

Motor Inspection 

The procedures for simple daily maintenance of the servomotor are shown in Table 5.1. Because AC servomotors are brushless, simple daily inspection is sufficient. The inspection periods in the table are standard scales. Determine the usage conditions and environment, and then decide an appropriate inspection period. Do not disassemble the servomotor for maintenance/inspection. Contact your Yaskawa representative or sales office if the servomotor is to be disassembled.

Digital Torque Amplifier Inspection 

Digital torque amplifier inspection is summarized in the table below. Although there is no need for daily inspection, perform inspections at least once per year

Component Replacement Timeline The components in the table below are subject to mechanical wear or degradation over time. Inspect these periodically for purposes of preventative maintenance. Digital torque amplifiers overhauled by Yaskawa are shipped with their system switches returned to their factory default settings. Be sure to verify these switches before operating.
