TTL is 0-5V logic where 0V is low, and 5V is high. With 24V logic, 0V is low and 24V is high. Application With the wider voltage swing, 24V logic is more noise immune ADVANCED Motion Controls’ Capabilities Drive models that feature either TTL or 24 VDC logic interfaces are offered 24 VDC interface is … TTL / 24 VDC

A drive will inhibit its output if it experiences a fault. If the fault condition goes away, the drive will normally re-enable. Sometimes it is desirable for the drive to remain inhibited even if the fault goes away. This behavior is called a latching fault. In some cases it is safer if the drive stays … Latching Faults

I/O (input/output) is very useful for expanding the functionality of digital servo drives. Inputs and outputs can be used to send signals between servo drives or between a servo drive and another piece of equipment without use of a network. Digital programmable outputs can be configured to activate for specific events such as in-position, at-velocity, … Programmable I/O

Programmable Limit Switches are digital outputs that are position dependent. The pulse width of PLS outputs can be based on time or position. Repeatability, rollover, and direction of motion are all configurable parameters. Benefits Ideal for applications that operate with varying speeds and require highly accurate timing of components Allows direct control of external machine … Programmable Limit Switch (PLS)

Homing routines provide the servo drive with the absolute position of the motor with respect to the machine, typically involving a sensor or switch located at a known position. Multiple homing routines can be used with the use of limit switches, home switches, and encoder index signals, and by defining the speeds for which a … Homing
