Product Description

The SERVOSTAR-446M-S is an accurate industrial servo amplifier built with the ability to control safety, performance and reliability. For data and information exchange over distance in a CAN signal environment the structure of speech transmission is basic, bandwidth modulation and DC coupling forming differential transmit receive operates. Thermal management is one of the controlled parameters, in particular, the internal fan is turned on whenever the temperature exceeds minus 58 C or heat sinks temperature exceeds 65 C. In fan-off operation mode, the temperature inside fan and fan body is maintained below 55 degree Celsius, and the temperature of the heat sink on fan is maintained under 60 degrees Celsius. The internal brake resistor non-tamper switch consumes <20W power with fan off increasing greater than to >30W with fan on, enabling great brake performance.

The amplifier has internal count pulses which means a turn consists of 220 of these rotators each rotated once, and for steady operation, power voltage is rectified and smoothed by DC bus link. It accommodates a number of fieldbus interfaces such as CANopen, PROFIBUS and SERCOS so that the control systems can be of various types.

It is very important to avoid any mechanical stress including movement of the components or changing insulation distances while transporting and handling the SERVOSTAR 446M-S during its adoption. Make sure the servo amplifier and motor are well within limits, going so far as to check that their rated voltage and rated current are the same as well as the wiring diagram. Setting the borne L1, L2, L3 or + DC, - DC terminals as maximum over 10% than the maximum permissible value is an act of throwing caution to the wind as such will damage the regen circuitry or better still destroy the servo amplifier.

Frequently Asked Questions about SERVOSTAR-446M-S

Q: How does the SERVOSTAR 446M-S manage thermal conditions?

A: The SERVOSTAR 446M-S has advanced thermal management features. The internal fan activates when the internal temperature exceeds -58C or the heat sink temperature exceeds 65C. In fan-off mode, the internal temperature is maintained below 55C, and the heat sink temperature remains under 60C. This ensures optimal operation and prevents overheating. The internal brake resistor consumes less than 20W of power with the fan off and more than 30W with the fan on, enhancing braking performance.

Q: What are the key safety and operational considerations when handling and installing the SERVOSTAR 446M-S?

A: When handling and installing the SERVOSTAR 446M-S, it is crucial to avoid mechanical stress, such as moving components or altering insulation distances, to prevent damage. It is also important to ensure that the servo amplifier and motor have matching rated voltage and current. Overloading the L1, L2, L3, or +DC, -DC terminals by more than 10% above the maximum permissible value can damage the regeneration circuitry or destroy the servo amplifier.

Q: What fieldbus interfaces does the SERVOSTAR 446M-S support?

A: The SERVOSTAR 446M-S supports multiple fieldbus interfaces, including CANopen, PROFIBUS, and SERCOS. This versatility allows it to be integrated into various control systems, providing flexibility for different industrial applications.

Q: How does the SERVOSTAR 446M-S handle data exchange in a CAN signal environment?

A: In a CAN signal environment, the SERVOSTAR 446M-S uses basic speech transmission structure, bandwidth modulation, and DC coupling for differential transmit-receive operations. This ensures reliable data and information exchange over distances, making it suitable for complex industrial setups.

Q: What is the role of internal count pulses in the SERVOSTAR 446M-S?

A: The SERVOSTAR 446M-S utilizes internal count pulses, with each turn consisting of 220 rotator pulses. This precise counting mechanism contributes to the accurate control of motor movements, ensuring steady operation. The power voltage is rectified and smoothed by the DC bus link, which further stabilizes the performance of the amplifier.

Internal Product Review

‘‘On the SERVOSTAR-446M-S, exceeding the maximum permissible values for terminals (L1, L2, L3 or + DC, - DC) by over 10% can damage the regeneration circuitry or potentially destroy the amplifier. Care must be taken during transportation and handling to avoid mechanical stress and ensure all components are within their rated voltage and current limits.’’
