Stepper Motor Power Stage Rack: MR8+ - PHYTRON - #1

Text version of the page

CONTROL The MR8+ is a minirack for up to 8 stepper motor power stages and a power and ServiceBus module (PSB). The power supply for max. eight power stages (24 to 48 VDC / 3.5 A per power stage), and the ServiceBus interface are provided by the PSB module via a backplane. The plugin position of the power stages determines its address. So the operating parameters, programmed via ServiceBus, are definitely assigned to a certain power stage. The integrated PSB module allows the cascading of up to 4 MR8+ (address switch 0-3). Thus, up to 32 axes can be configured centrally . The A 32-48 power stage is for bipolar control of 2 phase stepper motors up to 3.5 APEAK. The high step resolution up to 1/512 step guarantees very high smoothness with a positioning accuracy of 1/20 step. The 5 V push-pull inputs (Control pulse, Motor direction, Boost and Activation) are electrically isolated from the supply voltage. The parameterisation is done via ServiceBus or by setting switches (step resolution, current). Application The compact minirack is the perfect choice for up to 50 Watts shaft power for multi-axes application in science, optics, micro handling or in semiconductor manufactoring. Furthermore, the MR8+ is the best supplement for PC controllers, that can output Control pulses, Motor direction, Boost and Activation for several axes on an incremental interface. ServiceBus In Focus El. Isolated • 8 plug-in stepper motor power stages - Bipolar control of 2 phase stepper motors - Motor current up to 3.5 APEAK - Step resolution from 1/1 to 1/512 steps - Push-pull inputs: Control pulses, Motor direction, Boost, Activation - Electronical monitoring: overtemperature, short circuit, undervoltage - Programming the operating parameters by setting switches or by PC via ServiceBus • Power- and ServiceBus module (PSB): - 24 to 48 VDC supply voltage connector - ServiceBus interface for communication with the power stages - ServiceBus-Comm® PC software for Windows® included in delivery • Minirack housing for wall mounting - 270 x 120 x 155 mm (W x H x D) - Front side locking bar - EMC clamps to connect the cable shielding ServiceBus The ServiceBus is designed for communication with the power stages via RS 485/ 4-wire or USB. All settings can be entered at the PC, using the free ServiceBus- Comm® phytron software. So each axis can be parameterised and controlled by the ServiceBus. More programming possibilities Alternatively, readable ASCII-string instructions can be edited by individual software - e.g. with LabVIEW®, HyperTerminal or in C language. So it is possible to transmit parameters to each power stage without any problem during initialising or to change components and to evaluate status information. The MR8+ minirack can also be parameterised at each power stage: run current, step resolution and preferential motor direction are manually adjustable by setting switches.
