P05 Setting
Do not restart the inverter or reconnect it to a motor which is already running. Wait for the motor to
stop and the inverter to reach zero output frequency before attempting to run the motor/inverter
combination again.
If required, a running restart facility is provided by parameter P42
(see section 5.3.2) .
CAUTION
The three run–down modes operate as follows:
Ramp–Down
(P05 = 000, 004, 006 or 008)
The inverter output frequency will ramp–down at a rate set by parameter P03 until the minimum output
frequency (set by P07) is reached. At this point the inverter stops with no output.
Free Run
(P05 = 002, 003, 005, 007 or 009)
The inverter output stops immediately, allowing the motor to ‘freewheel’ to a standstill or to be stopped by other
means.
DC Injection Brake
DC injection braking is selected by setting parameter P11 to a value greater than zero. The inverter injects dc
into the motor for a period equivalent to the ramp–down time set by P03 plus one second.
