In the latest technical reference under point 22.h.iii you describe the drive cycle. There has been a question about this point before, but was not fully answered to our understanding. The drive cycle is created by 25 operation points (5 loads*5 throttle signals). If the throttle signal controlls the input current of the inverter, then this test would lead to either a stopped motor or an overspeed motor, from our point of view.
When the input signal is 2A and the load is 4A the motor does not start turning.
When the input current is throttled to 4A and the load is set to 1A the motor would run into the speedlimit(2500rpm).Is the input signal (throttle signal) still freely choicable or does it have to be one of the current/power/voltage throttle signals?
Your observations are absolutely true. It is the responsibility of the teams to ensure that the drive controller is able to respond to such apparently incompatible load conditions that may be incompatible with the throttle inputs — making the drive ‘idiot-proof’ — for instance giving a high throttle command when coasting down-hill, or not providing enough throttle while starting up-hill against an obstacle, etc.
