MDDLT55SF Panasonic MINAS A6SF Servo Driver – 1.5 kW, 200 V, D-Frame, with STO
The Panasonic MDDLT55SF is a D-frame servo driver from the MINAS A6SF series, the multifunction type of Panasonic’s A6 family. It is rated 1.5 kW and runs on single- or three-phase 200–240 V. It controls MINAS A6 servo motors in position, velocity, torque and full-closed modes, with a 3.2 kHz frequency response and a built-in safety function (STO). It accepts pulse-train, analog and Modbus commands and reads both the motor’s 23-bit encoder and an external scale. That makes it a single driver for anything from simple pulse positioning to high-precision full-closed axes.
