Three-Phase Reversing Motor Control
Three-phase reversing motor control can be implemented
with four SSRs as shown in the connection diagram. The SSRs
work in pairs with SSR1 and SSR3 operated for rotation in one
direction and SSR2 and SSR4 operated for rotation in the
reverse direction. The resistor R1 as shown in the connection
diagram protects against line-to-line shorts if SSR1 and SSR4
or SSR3 and SSR2 are on at the same time during the reversing
transition period. Use the following table as a guide to the
proper selection of an SSR for this application.
