1.1 Short Overview
MR 8 minirack is a modular power supply unit for wall mounting.
MR 8 is equipped with up to eight plug-in A 32-48 MINI stepper motor power stages and a
Power and ServiceBus (PSB) module. One free slot is reserved for further developments.
Cable clamps are mounted for shielding and strain relief at the bottom of the rack.
A fold-away interlock is used to save the plug-in board.
The supply voltage and ServiceBus are connected to the PSB module.
The PSB module can be connected to PC by USB interface, RS 422 or RS 485-4-wire
interface depending on the type.
The DIP switches used as address switches allow to operate up to 4 miniracks with 32
power stages on the ServiceBus.

DC Power Supply
The MR 8 supply voltage, 24 to 48 VDC max. 20 A is connected to the Power and
ServiceBus (PSB) module and looped through the backplane to the power stages.
The PSB module generates 5 V logic voltage for the A 32-48 MINI power stages.
Interfaces
Every minirack contains a PSB module with 2 interfaces available for connection to
PC/controller or another minirack.
•Power and ServiceBus module type PSB-USB: with integrated
USB-RS 485 converter
•Power- and ServiceBus-module type PSB-RS 485: without USB-RS 485 converter,
with address switches for max. 32 axes in 4 miniracks
Operation Modes
ServiceBus mode:
The ServiceBus is used for communication with power stages via RS 485 or USB.
The Windows® software can be user-friendly programmed by ServiceBus-Comm®. See
manual ServiceBus-Comm®.
Rotary switch mode
In rotary switch mode the parameters of the power stages can be set directly at each
power stage by rotary switches.
Remark:
The operating parameters can only be read by ServiceBus in the rotary switch mode.

1.5 Option: A 32-48 MINI Power Stage
A 32-48 MINI is a stepper motor power stage for bipolar control of 2-phase stepper motors,
which can be plugged-in the minirack.
The precision current control of the power stage A 32-48 MINI according to the patented
SYNCHROCHOP principle effects optimum running performance of the stepper motor.
The parameters – Run current, Step resolution and Motor direction – can be configured by
rotary switches or ServiceBus.
Step resolution can be set by the rotary switch:
Full step, half step, 1/4, 1/5, 1/8, 1/10 and 1/20 step.
You can program the following step resolutions in ServiceBus mode:
1/1, 1/2, 1/4, 1/5, 1/8, 1/10, 1/16, 1/20, 1/32, 1/64, 1/128, 1/256, 1/512 of a full step.
Motor currents from 0.24 to 3.5 APeak
Rotary switch mode:
Run current can be set in 15 steps from 0.15 to 2.00 Arms.
ServiceBus mode:
Phase currents can be programmed from 0.10 to 2.50 Arms in 10 mA steps.
Inputs
The inputs Control pulse, Motor direction, Boost and Activation are designed for push-pull
controlling. The inputs are optically insulated from the power stage supply voltage by
optocoupler.
Output error
The output error opens in case of short circuit, overcurrent, undervoltage or
overtemperature.
