RTA X-PLUS S Stepper Drives with STO (Safe Torque Off) function from Micromech

RTA X-PLUS S stepping motor drive series with step and direction interface and direct mains input (110v AC to 230v AC)

The X-PLUS S series features an internal rectifier capable of transferring more than 330V DC to the motor.

Ideally suited to applications requiring high dynamic performance and high reliability.

Key Features:

• STO function (SIL3)
• Error detection monitor.
• Electronic damping facility to reduce noise and mechanical vibration at low and medium speed ranges.
• Optoinsulated and differential input/output signals provide easy interfacing with many commonly used control systems and ensure a high level of noise immunity.
• For NEMA 34 or larger stepping motors rated for high voltage.
