Compact Power
• 80V operating voltage
• 4A Phase current
This new driver for the upper power range offers high-tech on minimizsed space. 2-phase stepping motors can be run with up to 4 A bipolar. The integrated, powerful micro processor takes care about a user friendly drive with high flexibility.
Intelligent Controller
Online-operation is not only possible via the standard operation mode with signals pulse and direction but also possible with the fitted serial interface (either RS232 or RS485).
A 7-Segment-LED-Display informs the user about the status of the drive or the respond of the protection devices.
Reliability
Helpful are all in- and outputs of the driver which are galvanic isolated with opto-isolators from the operating power. The driver is short circuit proofed and protected against over voltage and under voltage.
High Resolution
Due to the micro step run the motor can work nearly vibrationfree with a resolution of 1.8° (full step) up to 0.225° (1/8 step).
