Safety options can help reduce machine downtime and increase productivity. To help you protect both your personnel and equipment, a variety of PowerFlex® drives are available with safety features. The PowerFlex 525 AC drives include embedded Safe Torque-Off as a standard feature. Safe Torque-Off is an optional feature for the PowerFlex 40P, 70, 700H, 700S, and 750-Series AC drives, which also support Safe Speed Monitor functionality. Additionally, you can configure drives without a safety option using the MSR57P Safety Relay.
