Motor control system with selectively operated A/D convertor

A motor control system for individually feedback-controlling a plurality of servomotors comprising:

• motor drive means for converting DC power into AC power and applying said AC power to said plurality of servomotors;
• and
• current detecting means for detecting the current value of said AC current to feed back the current value thus detected to said motor drive means,
• wherein said motor drive means, said current detecting means, and a memory in which gain adjustment data and offset adjustment data of said current detecting means have been stored are accommodated in a casing for every at least two of said plurality of servomotors.

• current detecting means for detecting the current value of said AC current to feed back the current value thus detected to said motor drive means;
• an A/D converter means for converting an output signal of said current detecting means into a digital signal;
• and
• a memory in which gain adjustment data and offset adjustment data of said current detecting means have been stored,
• wherein said gain adjustment data stored in said memory being gain correction data which are obtained for a plurality of rated drive currents with offset components removed which correspond to said offset adjustment data.
