Differences Between Single-Channel STO and Dual-Channel STO S700 Drives

This article will help you understand the differences between older S700 (S701-724) drives with single-channel STO and newer dual-channel STO S700 drives. 

As of July 2015 the S700 drives came standard with dual-channel STO. The dual-channel S700 can be operated in single-channel mode without any restrictions. The STO inputs must be jumpered between X4A/3 and X4B/6.
