SERVO DRIVES & MOTION CONTROL SMT-BD1 digital drive for AC sinusoidal synchronous motors

! This is a general manual describing a series of servo amplifiers having output capability suitable for driving AC brushless sinusoidal servo motors. This manual may be used in conjunction with appropriate and referenced drawings pertaining to the various specific models. Instructions for storage, use after storage, commissioning as well as all technical details require the MANDATORY reading of the manual before getting the amplifiers operational. Maintenance procedures should be attempted only by highly skilled technicians having good knowledge of electronics and servo systems with variable...

CINFRANOR SERVO DRIVES & MOTION CONTROL

Chapter 1 - General description 1- INTRODUCTION Series SMT-BD1 digital servo modules are PWM servo amplifiers that provide speed control for AC sinusoidal motors (brushless) with transmitter resolver. The pluggable SMT-BD1 system is available as a single-axis block version or as a multi-axis version that can receive up to seven axes in a standard 19" rack including the power supply. * The basic amplifier module SMT-BD1 / a or b provides the speed control for AC synchronous motors with +/- 10 V analog speed input command. The SMT-BD1 / c version with its specific option board allows the direct...

Motors and resolvers are grounded via their housing. If a reference of potential is existing, like a main chassis or a cabinet, with a low impedance between the different elements, it should be used with short connections and this reference potential should also be grounded. Long reference potential connections are suitable ONLY if these connections have a very low impedance...
