Installation clearance of inverters

Keep 1 cm or more of clearance for 3.7 K or smaller, and 5 cm or more for 5.5 K or larger.If the clearance is too small, the cooling effect is lowered. Secur... More Details >>

Stop-on-contact control

1. You can implement stop-on-contact.2. When implementing stop-on-contact, use the inverter to decelerate the motors to reduce the impact upon stop-on-contac... More Details >>

Terminal FM

Since the terminal FM is designed with 8 V peak pulse voltage output, it cannot output 10 V.Since the terminal AM is an analog output of 0 V to 10 V, use thi... More Details >>
