Kollmorgen S70601-NA
Product Introduction
Smallest continuous-current member of the S700 line. Same architecture as S70602 but rated 1.5 A RMS at 400–480 VAC (2.5 A at 208 V). The “-NA” suffix denotes no expansion card and standard single-channel STO (SIL CL2 / PLd). Used for small AKM2x/AKM3x motors, micro-actuators, valve simulators, and medical automation axes.

Features
-
Identical control firmware to larger S700 units
-
IEC 61131 macro programming inside drive
-
Autotuning, cogging suppression, notch filter
-
Internal brake resistor standard, external resistor connectable on DC bus
Structure and Materials
Same aluminum-finned chassis as S70602, narrower power board, single IGBT phase module.
Working Principle
Same PWM field-oriented control principle as S70602 with reduced current sense range.
Installation and Notes
-
Same panel/clearance rules as S70602
-
24 VDC logic supply required even when mains is off for STO state management
-
Not for motors with rated current above 1.5 A continuous unless heavily derated speed is acceptable
-
Single-channel STO is not sufficient alone for SIL3 applications; add external contactor or safety relay
Applications
Micro pick-and-place heads, optical alignment stages, medical pump actuators, test bench servos.
