FG Signal Timing Chart
This function involves setting the triangular wave cycle (carrier cycle) necessary for generating PWM
signals.
Carrier frequency: f
Example: If f
The common-mode voltage range is V
This pin outputs the revolution pulses based on the Hall signal. The TB6586FG outputs one (1) pulse /
electrical angle and the TB6586AFG outputs three (3) pulses / electrical angle. In the case of the
TB6586FG, this pulse is generated via the U phase Hall signal. For a Hall element, the pulse is converted
to digital and then output. For a Hall IC, it is output in the equivalent waveform. In the case of the
TB6586AFG, the up-down edges of the U, V and W phase (respectively) are combined and then generated.

Number of FG pulses for an 8-pole motor:
• TB6586FG: 4 pulses per revolution (4 ppr)
• TB6586AFG: 12 pulses per revolution (12 ppr)
