Can I use an electromechanical card relay between the PLC and the DC Brushless driver?

Filed under: Speed Control Motors — mota @ 3:04 am

The solid-state relays (SSR) are more expensive than the electromechanical. Would the motor driver have a problem with the bounce created from the electromechanical relay?

Using an electromechanical relay is no problem. The AXH driver accepts both dry contact switches as well as solid state relays. All it needs is a path to ground. The bounce created from an electromechanical relay will not create a problem because the system is not fast enough to where any bounce would make a difference. Please see pages 20 and 21 from the AXH manual. www.motadistribution.com
