MSD MINI 172-140 POWERPACK stepper motor power stages meet the most stringent requirements. It includes a supply unit and can therefore be connected directly to the 230 VAC mains voltage. The stepper motor power stage control signals can be delivered by all types of control units, provided they integrate a stepper motor interface. These power stages are used to connect 4-, 6- or 8-lead two-phase stepper motors. Furthermore, they can supply a permanent magnet motor brake. * phase currents up to 12 Ar.m.s. at 140 V * Synchronous chopped current regulation according to Phytron s patented SYNCROCHOP principle * Setting switches are used to program individually the run and stop currents as well as the boost current during acceler-ation and deceleration. * Dynamic boost function "OVERDRIVE" within the higher frequency range. * A setting switch selects the resolution: full step, half-step, 2/5, 1/4, 1/5, 1/10 or 1/20 step. This switch is also used to program the preferential motor direction. * Optocoupler-isolated signal inputs: The use of RS422 signals is recommended to increase immunity to disturbance signals. The unit can also be driven by open collector type signals. * Mains supply: A ring transformer provides galvanic separation. * Compact and rugged design adapted for wall mounting with brackets or 19"-rack mounting. taken out of a working machine (Msd mini 172-140 powerpack was posted and is owned by: Belinda Murray) |
