Notes: 1. To increase the regenerative braking frequency, install cooling fans (two units of 92 mm × 92 mm, minimum air flow: 1.0 m 3 /min), and then change [Pr. PA02]. The cooling fans must be prepared by user. 2. By installing a thermal sensor, create a safety circuit that shuts off the main circuit power supply when abnormal overheating occurs. 3. G3 and G4 terminals are thermal sensor. G3-G4 opens when the regenerative option overheats abnormally.
