In certain applications, attaching a brake to the axis is essential. An example might be: when the system is lifting a vertical load that cannot be allowed to fall due to a power failure, a motor overload shutdown, a drive failure, an emergency stop interlock, a cable failure, etc. The SST servo drive has all of the signals required to run a failsafe power-off brake attached to your mechanics. By adding only two low-cost solid state relays to a SST servo system, you can run a failsafe brake to protect your machinery from a runaway axis under all of the conditions aboveBy running the brake and protecting the load/mechanics automatically, an SSt servo system can simplify control software development. Usually the software requirements are reduced because less interlock in machine operations is required when it is known that the brake will actuate (and stop the load quickly) during a fault, and because the sequencing requirements after a fault are reduced.
Using the SST servo drives failsafe brake operation will, in general, increase the system reliability of your machine. Faults, including software errors, are far less likely to cause damage. Also recovery time after a "soft" fault is typically reduced.
