There are two ways to control motor brake by G120D:
Firstly, external lock circuit is controlled by DO point of frequency converter, and internal lock logic of frequency converter is used.
Secondly, through the output terminal of converter direct control motor brake coil, G120D converter direct control motor brake coil can provide 180V DC current, direct control motor brake coil suction, so motor brake does not need rectifier block conversion power supply, when used with SEW motor, it needs to skip the rectifier block in the motor. The supply voltage of the motor brake coil is 180 V DC, or 0.45 times of the input voltage.
