Motor control functional explanation
1, Blank Time
A Mask time setup of the recovery current generated in Motor ON Timing is performed.
2, Off Time
The Motor OFF time after Itrip is set up.
3, Fast Decay Time
Fast Decay time in Mixed Decay Mode is set up.
(invalid at the time of Slow Decay and External PWM)
4, Sync.Rect
4-1, Active :FET is all turned off by current zero among Decay.
4-2, Passive :Reverse current is passed to a Vref setting value,and FET is all turned off after that.
Conditions1 :Internal PWM
Sync.Rect.EnableControl1 “H ”
Mixed Decay Mode
State1 :Only the inside of Fast Decay is effective.
(When not reaching into Fast Decay at the above- mentioned setting value,it moves Slow Decay)
Conditions2 :External PWM
Sync.Rect.EnableControl1 “H ”
Fast Decay Mode
5, Sync.Rect.Enable
5-1, Disabled :Sync.Rect.EnableControl1 “L ”
→
Decay by the external diode is performed.
5-2, Enabled :Sync.Rect.EnableControl1 “H ”
→
Decay with an internal transistor is performed.
6, Word Select
The taking- in place of serial data is set up (OUT1,OUT2,OUT1/OUT2).
7, Internal PWM
Decay is set up.
Decay Mode :Mixed /Slow
Mixed Decay :Fast Decay to Slow Decay
8, External PWM
A Decay setup at the time of the external control by EN terminal
Decay Mode :Fast /Slow
9, Phase Control
The direction to which current flows is set up.
Reverse: Phase B
→
Phase A
Forward: Phase A
→
Phase B
10, DAC
The current which FET passes is set up.
Itrip is set up.
