Series of ministep bipolar chopper drives, suitable for driving medium power two-phase stepping motors, with four, six or eight terminals.
Compact, easy to use and cost-effective solution. This system is designed for easy mounting inside a metallic electrical cabinet.
Target: medium and medium-low power applications without special configuration requirement, but needing great dynamic performance, high reliability, low acoustic noise and mechanic vibrations reduction.
Version: drive housed in a metallic box in 110 x 108 x 34 mm, equipped with plug-in connectors.
Range of operating voltages: 24-75 VDC.
Range of current: 1.9-6 Amps. Setting up to eight possible values by means of a dip-switch.
Microstepping: 400, 500, 800, 1.000, 1.600, 2.000, 3.200 and 4.000 steps/revolution. Setting by means of a dip- switch.
Automatic current reduction at motor standstill.
Protections:
-Protection against under-voltage and over-voltage.
-Protection against a short-circuit at motor outputs.
-Overtemperature protection with thermal sensor.
Optoinsulated inputs compatible with differential control signals.
Possibility to switch off motor current with an external logic signal.
High-efficiency CHOPPER with MOSFET final stage output.
Electronic damping facility for further acoustic noise and mechanic vibrations reduction at low and medium speed.
Available a version with built-in oscillator, with speed range from 14 to 450 rpm. Setting by means of dip-switches.
