SYSTEM WIRING
The SP3 Power Block is a PWM amplifier designed to drive a servo motor by using a PWM
input from an external controller, specifically the Delta Tau Data Systems, Inc. PMAC
2 multi-
axis controller. The SP3 consists of a smart power stage and an intelligent interface card for the
switching power amplifier. The product allows for dynamic system performance and excellent
control capabilities. Extensive protection features include encoder loss detection, peak over-
current protection, I
2
t drive protection, motor and drive over-temperature protection, and over-
and under-voltage protection. Encoder and Hall effect signals are supported. All faults are
displayed on a 7-segment display.
The SERVO
STAR
SP3 Power Block has two options: the Standard Option and the Integrated 8F
Option. The Integrated 8F Option includes the interface features of the Delta Tau Data Systems,
Inc.'s Accessory 8F
digital interface board, which is essentially built directly into the drive
itself.
The following tables provide information about the main power terminal block and the optional
24 VDC logic power connector. Kollmorgen can provide cabling for each of these connections.
MAIN POWER CONNECTOR
The main power terminal block is on the front of the unit, and is protected by a plastic cover
which snaps closed.
