Goodrive3000 series medium voltage VFD
1: Two-wire control 2, the enabling separated from the direction. In this mode, FWD is the enabling terminal. The direction
depends on the defined REV state.
2: Three-wire control 1. This mode defines Sin as the enabling terminal, and the running command is generated by FWD,
while the direction is controlled by REV. During running, the Sin terminal needs to be closed, and terminal FWD generates
a rising edge signal, then the VFD starts to run in the direction set by the state of terminal REV; the VFD needs to be
stopped by disconnecting terminal Sin.
The direction control is as follows during running:
Sin
ON
ON
ON→OFF
Sin Three-wire control; FWD: Forward running; REV: Reverse running
3: Three-wire control 2. This mode defines Sin as the enabling terminal, and the running command is generated by FWD
or REV, but the direction is controlled by both FWD and REV. During running, the Sin terminal needs to be closed, and
terminal FWD or REV generates a rising edge signal to control the running and direction of the VFD; the VFD needs to be
stopped by disconnecting terminal Sin.
