24 SERIES STEPPER DRIVES PVP2460 & PVP2490 PVP2460 pictured only The Series 24 range of stepper motor drives, mounted on the board, which allows a wide range of manufactured by Alzanti, have been developed to meet motors to be from NEMA frame size 23 to 42 to be the growing demand for high performance, cost effective, driven, at voltages up to 85Vdc. bipolar drivers. They have been designed to be compatible with the specifications of many stepper Other standard features include: Full/half step mode motors, with options available to suit numerous selection over temperature protection overload applications. PWM chopper regulation provides a very protection motor current boost and standby selection efficient motor drive stage, extending the useful speed output stage disable function. The PVP2490 is fitted range of motors whilst reducing heat dissipation and with a force cooled heatsink assembly. power consumption. Optional extras include:- The PVP2460 delivers a maximum continuous motor 1. A simple on-board oscillator for manual speed control. current of 6 Amps per phase and the PVP2490 a 2. By fitting the PVP179 the board can be converted to a maximum continuous current of 9 Amps per phase. micro stepping drive with resolutions from 1/5 to 1/32 of Motor phase currents are programmable via a DIL switch one step.
