sDetermining the Output Current IO
(Control Current)
The main factors that determine the output current are current
sense resistor RS, supply voltage Vb, and variable current resis-
tor RX.
(1) Normal mode
To operate a motor at the maximum current level, set RX to
infinity (open).
From Fig. A, when the maximum current ripple is designated
as IOH, its value will be,
VRSH
IOH=
...................................................................... (1)
RS
VRSH can be calculated as follows:
VRSH=0.19×Vb−0.03 (center value) ............................... (2)
From equations (1) and (2), the output current IOH can be
calculated as follows:
1
IOH= (0.19×Vb×-0.03)
RS
The relationship between IOH and RS is shown in Fig. B.
(2) Power down mode
When an external resistor RX is connected, VRSH changes as
shown in Fig. C even when RS is retained. Obtain a power
down output current IOHPD from Fig. C and equation (1).
sRelation between Output Current IO (Control
Current) and Motor Winding Current IOM
The SI-7502 uses the total current control system; therefore,
the output current IO is different from the motor winding current.
In a general pentagonal driving system, the current flows as
shown in Figure D. The relation between IO and IOM is as follows:
IO=4×IOM
With some driving systems, the relation can also be as follows:
IO=2×IOM
