Drives GCD MINI Stepper Motor Power Stage with Indexer and Plain Text Display Technical Information Ministep stepper motor power stage for bipolar control of two-phase stepper motors Indexer for exact positioning PLC mode or online mode Parametrization and configuration in the online mode with IPCOMM 8 Digital inputs, 4 digital outputs for PLC mode 2 Limit switches Input logic 24 V Phase currents from 0.14 to 9 APEAK Power supply: 50 VAC or 70 VDC Admissible range: 17 to 50 VAC or 24 to 70 VDC Step resolution up to 1/8 step Plain text display 2 x 8 digits Compact design 70 x 150 x 127 mm User-friendly screw connectors Fully EMC compliant metal housing DIN rail or wall mounting Prepared for mounting an external 24 V fan at the bottom of the housing IPCOMM communication software included in delivery Plain Text Display GCD MINI is an ’intelligent’ stepper motor power stage with indexer for two-phase stepper motors up to 9 APEAK. Absolute and relative motion commands can be executed from a PLC or online on the PC. PLC Mode The GCD power stage receives motion commands from a PLC via the digital inputs and outputs. Online Mode The GCD receives motion commands from a PC via RS 485 or RS 232 interface. Indexer The embedded indexer allows a processor controlled selection of the best step resolution. 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. èèèèèè The GCD Stepper Motor Drive A two-line plain text display and three menu buttons are sufficient for operating the GCD. The parameters run, stop and boost current can be programmed and changed in the SETUP menu at any time. The TEST menu allows to drive the motor for test with the programmed parameters, to set the outputs and to display the input states. Active parameters are displayed during motor running: phase current, voltage or power stage temperature (optional). The plain text display changes in case of an error: short circuit, under voltage or over temperature.
