CINFRANOR SERVO DRIVES & MOTION CONTROL

! 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. Maintenance procedures should be attempted only by highly skilled technicians (EN 60204.1 standard) using proper test equipment. The conformity with the standards and the "CE" approval are only valid if the items are installed according to the recommendations of the racks and amplifiers manuals. The user assumes any responsability...

SERVO DRIVES & MOTION CONTROL

Chapter 1 – General description 1- INTRODUCTION Series SMT-BD1/p servo modules are PWM servo amplifiers that provide current, speed and position control for AC sinusoidal motors (brushless) with transmitter resolver. The SMT-BD1/p servo drive is 220 VAC or 400 VAC mains operated. The SMT-BD1 plug-in system with 220 VAC power supply is available as a single-axis block version or as a multiaxis version that can receive up to six axes in a standard 19" rack including the power supply. The SMT-BD1 plug-in system with 400 VAC power supply is available as a multiaxis version that can receive up to...

Several potential conductors in the same sleeve must be twisted...

2.2 – Connectors shield connection RULE The shield should never be interrupted or corrupted over the whole cable length. Self-sticking copper ribbon if necessary, for increasing the shield diameter in order to get it correctly tightened under the clamp Motor connector for resolver and motor The cable can be soldered on the shield because the connector box is metallic. This solution does not exactly meet the EMC requirements but it is acceptable. Metallic or metal plated plastic SUB-D pin package 360° shield ensured by the tightening clamp X As short as possible Ground U V W UV W X The fastening...

2.3 - Motor and resolver cables Motors and resolvers are grounded via their housing. Cable inputs should be made by means of metal connectors with collars allowing the 360° shield connection. The resolver cable must be pair twisted and shielded (sin, cos, ref.). Motor cables MUST also be shielded. 2.4 - Serial link cables The serial link cable must also be shielded according to the above mentioned shield connection recommendations. CAUTION Command cables (resolver, serial link, Profibus) as well as the power must be connected and disconnected with amplifier OFF. 3 – FIRST AMPLIFIER COMMISSIONING...
