Table 4‑62 The Components of SD1X

Components		Function
BD554 (IPM Board)	Logic Part	PWM signal from the 6-axis servo drive is converted to upper and lower drive signal of IPM, and the error is processed.
	Gate Power Module	Generation of gate power
	Current Detection Unit	Detection of the current flowing into the motor
Other Components	Heat Sink	Emission of heat generated from IPM
	IPM	100A Switching Device
