Whilst reading the Lenze 534 manual ive come across another requirement....

If a reverse motor direction is required a simple polarity change is required using one of the contactors, however the motor motion must stop before the reverse direction is activated, I will need to incorperate a timer to allow for the motor to come to a standstill before the reverse is activated, I can tune the time once I know how long that takes, I could also introduce electrodynamic braking to reduce the changeover time, I will have to investigate all that before I complete a reverse control but that will be a secondary to getting it moving in a forward direction first...
