Product Description:

The DSM007 is a compact servo amplifier manufactured by Kollmorgen for the DSA SERCOS Drives series. This drive converts incoming power and closes a velocity loop for brushless servomotors, allowing coordinated motion axes to be linked through the SERCOS fiber-optic network. Within an automation cell, it regulates motor speed and torque, adapts to command tracks from a motion controller, and returns real-time status data for synchronization. Its small form factor supports cabinet installations where multiple axes must share limited panel space.

Analog velocity commands are accepted at ±10 V, giving the controller a standardized electrical range that matches typical motion cards. The power supply must deliver 5 A of continuous input, which the converter turns into a regulated motor phase current of 2.5 A under steady-state load. This current allows it to supply 0.5 kW of continuous mechanical output to the motor shaft. During acceleration or transient disturbances, the drive can source up to 7.5 A, providing short bursts of additional torque without exceeding component limits. These electrical values affect thermal loading and cable sizing during installation.

Dynamic energy created during deceleration is routed to an external shunt rated for 300 W continuously and 2.2 kW at peak, protecting the internal bus capacitors. High-speed position sources are supported through a master encoder input that handles 1 MHz quadrature, while the velocity loop closes at 300 Hz for responsive yet stable regulation. Three digital inputs, two digital outputs, and eight presets permit local mode selection and status signaling, and up to 32 drives can share the ring address space. Communication with supervisory equipment is carried on RS-232 or four-wire RS-485 links, and the housing weighs 1.68 kg for easy panel mounting.
