6.5.4.1

Interface description - X120 (converter side)

Overview
The servo drive system supports three types of encoders:
• Absolute encoder, 17-bit single-turn
• Absolute encoder, 21-bit single-turn
• Absolute encoder, 21-bit single-turn +12-bit multiturn
The converter connects to the encoder of the motor on the interface X120.
