2 Introduction
2.1 Brief Description
The SIXpack 2 is a highly integrated stepper motor controller for six 2-phase stepper motors with a coil current of
up to 2000 mA each. It is the fully compatible advancement of the QUADpack and SIXpack with enhanced ratings
and functions.
The SIXpack 2 comes in a rugged box package with tested electromagnetic compatibility. It is easy to use and the
ideal solution for stepper motor control in an industrial environment.
A DSP supported by special hardware allows a powerful function set and a wide stepping frequency range for all
motors. The SIXpack 2 is equipped with RS 232, RS 485 and CAN-Interface.
2.2 What do I have to know about my application
Before the SIXpack 2 is set up the demands of the application to the stepper motors should be clearly defined.
What are the right motors? The SIXpack 2 supports 2-phase stepper motors. The peak motor power is defined by
the modules supply voltage and the coil current of the driver ICs (max. 2000mA).
The actual motor position is not known after power on. Thus a reference search has to be made in order to find
the absolute position. Most applications use switches or photo interrupters to detect the reference position. In
some applications a mechanical limit point without any detector switch is appropriate. The SIXpack 2 does not
support encoders.
To control the SIXpack 2 there are different interfaces (RS232, RS485, CAN). It is not relevant to the SIXpack 2 if it is
controlled by a desktop-PC, another machine operating unit or a set up with microcontroller. A stand alone
operation is not possible.
2.2.1 The SIXpack 2 does not support
Stand alone operation:
The SIXpack 2 can not operate without initialization and control by a host
connected to one of its serial interfaces.
Closed loop operation: The SIXpack 2 has no encoder interface and there is no other possibility for
nominal/actual value comparison for motor position. It is possible to compare the
internal position counter with the status of the reference switch. If an invalid
value is detected an automatic reference search can be started automatically.
External output stages: There is no possibility to connect external power stages to the SIXpack 2 to
increase the maximum motor rating above 2A / 48V.
