! This is a general manual describing a series of servo amplifiers having output capability suitable for driving AC brushless sinusoidal servo motors. 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 speed (EN 60204-1 standard) and using proper test equipment. The conformity with the standards and the "CE" approval is only...

CHAPTER 1 - GENERAL DESCRIPTION 1 - INTRODUCTION Series SMT-BD2/m digital servo modules are sinusoidal PWM power amplifiers that provide position, speed and torque/force control for AC brushless motors (rotating or linear) equipped with encoder only or encoder with Hall Effect Sensors (HES) for the position feedback. The SMT-BD2/m digital servo drive is 220 VAC or 400 VAC main operated. The SMT-BD2/m plug-in system with 400 VAC power supply is available as a multiaxis version that can receive up to three axes in a standard 19" rack including the power supply. The SMT-BD2/m plug-in system with...

OINFRANOR3 - REFERENCE TO THE STANDARDS The 220 VAC version of the SMT-BD2/m amplifiers operating in the BF rack, which is equipped with the mains filter BF-35 or 70, has been approved for its conformity with the Electromagnetic Compatibility standards: • EN 55011, Group 1, Class A regarding the conducted and radiated radioelectric disturbances, The 400 VAC version of the SMT-BD2/m amplifiers operating in the BF-400 rack, which is equipped with the mains filter F400-35 or 70, has been approved for its conformity with the Electromagnetic Compatibility standards: • EN 55011, Group 1, Class A regarding...

1.1 - Current ratings for the 220 VAC amplifier version Auxiliary supply voltage 310 VDC ( 200 VDC < Uaux < 340 VDC max.) Motor terminal to terminal output voltage 200 Vrms for 310 VDC bus Authorized output currents for current pulse mode operation (I2t protection in fusing mode) * Maximum ambient temperature = + 40° C, fan 1 = 56 l/s, fan 2 = 90 l/s. Note: The SMT-BD2/m-X/Xr amplifier types are equipped with an additional heatsink in order to improve the heat dissipation and increase their rated current. The width of these amplifier types is then 18 TE instead of 12 TE. Minimum inductance between...

OINFRANOR 3 - MAIN PROTECTIONS 3.1 - Displayed protections PROTECTION All these faults are memory stored in the amplifier except for the "Undervolt." fault. The reset of a stored fault can be made: - by means of the RESET function in the Visual Drive Setup software - via the fault RESET input (pin 13 of the X4 connector) - by switching off the amplifier power supply.

CINFRANOR 3.2 - Fuse protection F1 : Control of the average DC current of the power board supply (see Hardware adjustments in chapter 5). F2 : Control of the average DC current of the logic board supply (see Hardware adjustments in chapter 5).
