Start-Up
– Drive waits for PFC Start Delay(parameter 8122). Modulation is not allowed
because drive has to wait that all contactor are stabilized.
– Modulation is allowed. Modulation starts from zero speed. After F
out
rises over
Start Frequency 1, Aux. Mot. Start Delay starts (parameter 8115).
– When Aux. Mot. Start Delay elapses then drive coasts to stop and RO1 is
opened.
– Drive waits for PFC Start Delay (parameter 8122). Meaning of this delay it to
wait contactors to stabilize. If there is some oscillation in Motor 1 contactors
when closing RO2, then contactors might go to wrong state.
– Drive close RO2. This is new plae for Speed Regulated Motor. Modulation is
not allow yet.
– Drive waits for PFC Start Delay (parameter 8122). Modulation is not allowed
because the drive has to wait that all contactors are stabilized.
– Drive close RO1. Motor in RO1 is connected directly to the network(constant
speed) and modulation is allowed. Drive start accelerating from zero in RO2.
• Stoping motors goes like in standard PFC. See the figure.
