Auxiliary Logic Supply Power
Supplying power separately to the logic supply is useful if the MAX-430 logic power must stay
ON when the motor power must be turned OFF. When DC power (24 VDC) is supplied to the
Auxiliary power input at TB1 pins 9 and 10, only the logic supply is powered. This is useful
when the operational status of the MAX-430 drive is needed at the SSO output (P1 pin 6) without
applying main power. See “AC and DC Power Connections” on page 2-4.
Connecting The Motor
When a positive voltage is applied to VCS+ with respect to VCS- (P1 pins 1 and 2), and the
motor and tachometer leads are connected to the drive as explained below, there will be clock-
wise (CW) motor shaft rotation as viewed from the shaft end of the motor. Likewise, there will
be counterclockwise rotation when a negative voltage is applied to VCS+. To reverse direction,
while keeping the voltage polarity on VCS+ and VCS- the same, both motor leads and tachometer
leads need to be reversed. To reduce the effect of radiated electrical noise it is suggested that the
motor leads and the supply leads be run as twisted pair shielded cable. It is also advisable to
keep the motor and power leads away from any signal leads. See “AC and DC Power Connec-
tions” on page 2-4.

Logic Inputs and Outputs
The diagram below illustrates the suggested method of connecting the inputs and outputs on
P1 and P2. The following three sections (“Connecting Inputs”, “Internal Connections (FAC, RAC
and INH)” and “Connecting Outputs”) explain the function of each input and output in more
detail.
