PARAMETER DESCRIPTION 251
5.11.3 DC injection brake before start

Before operation, motor may be in rotating state due to external force or inertia. If inverter suddenly start operation,
the output current may be too large, causing motor damage or trigger driver protection.

DC injection brake before start

If 10-05(P.242)=0, DC brake function before start will be off. If 10-05(P.242)=1, DC brake is on, when inverter start,
it will inject DC voltage (with 10-07(P.244) value) into the motor coil to lock the rotor. DC brake will maintain for a
period of time (10-06(P.243) value) before motor starts to run.
