Phytron: Stepper Motor Drive with Power Supply Unit (GSP Series)

GSP Stepper Motor Power Pack
The GSP power pack is an ’intelligent’ drive for two-phase stepper motors. The GSP vario power pack is designed for stepper motors up to 9 A (70 V motor voltage). The GSP maxi PEAK power pack is used for larger stepper motors up to 17 A (140 V motor voltage). PEAK Motor currents can be set individually in 16 stages. The GSP is controlled by a microcontroller which receives the control commands from a superior controller, e. g. from a PC or a PLC. So it is possible to operate in two operation modes: online or PLC mode. The drive is connected to the superior controller via RS 232 or RS 485 (4-wire) serial interface.

Axis Controller
The GSP power packs operate with a dynamic ministep / full step changeover.
The step resolution is automatically adapted to the frequency: 1/8 1/4 1/2 full step 1/2 1/4 1/8.
Ministep guarantees high resonance suppression during a slow run. Full step enables the complete motor power at high frequencies.
The GSP use phytron’s well tried technology, now with enhanced field synchronized current chopped regulation based on the patented SYNCHROCHOP principle developed by phytron.
