
Make sure to set 01-11(P.13) (start frequency) to zero when using this function.
Note: 1. If set 10-04(P. 152) to 6%, output voltage of zero speed is 6% of 01-04(P. 19) (base frequency voltage).
2. This function is only valid under V/F control. Please refer to parameter 00-21 (P.300) for the setting of motor
control mode.
5.10.3 DC injection brake before start
 Before starting, 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 inverter protection.


If 10-05(P. 242)=0, DC brake function before start will be off. If 10-05(P. 242)=1, DC brake before start 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.
