Place of Origin
* Are external motor disconnects required between the motor and the VFD? Service disconnects at motor loads are very often used for maintenance purposes. Normally, removing a load from a VFD while operating does not pose a problem for the VFD. On the other hand, introducing a load to a VFD by closing a motor disconnect while the VFD is operational can be fatal to the VFD.
When a motor is Started at full voltage, as would happen in this case, high currents are generated, usually about six times the full load amps of the motor current. The VFD would see these high currents as being well beyond its capabilities and would go into a protective trip or fail altogether. A simple solution for this condition is to interlock the VFD run permissive circuit with the service disconnects via an auxiliary contact at the service disconnect. When the disconnect is closed, a permissive run signal restarts the VFD at low voltage and frequency.
* Are there power factor correction capacitors being switched or existing on the intended motor loads? Switching of power factor capacitors usually generates power disturbances in the distribution system. Many VFDs can and will be affected by this. Isolation transformers or line reactors may be required for these applications.
Power factor correction at VFD-powered motor loads is not necessary as the VFD itself does this by using DC internally and then inverting it into an AC output to the motor. All VFD manufacturers warn against installing capacitors at the VFD output.
Variable Frequency Drive Technologies
Three basic types of variable frequency drives offer certain advantages as well as disadvantages
depending on your motor application. The new flux vector drive is also discussed.
While all variable frequency drives (VFDs) control the speed of an AC induction motor by varying the motor's supplied voltage and frequency of power, they all do not use the same designs in doing so. There are three major VFD designs commonly used today: pulse width modulation (PWM), current source inverter
Installing the Servomotor
Servomotor SGM and SGMP types can be installed either horizontally or vertically. However, if the Servomotor is installed incorrectly or in an inappropriate location, the service life will be shortened or unexpected problems will occur. To prevent this, always observe the installation instructions described below.
Anticorrosive paint is coated on the edge of the motor shaft. Clean off the anticorrosive paint thoroughly using a cloth moistened with thinner.
Avoid getting thinner on other parts of the Servomotor when cleaning the shaft.
When the Servomotor is to be stored with the power cable disconnected, store it in the following temperature range:
Between −20°C and 60°C
The Servomotor SGM and SGMP types are designed for indoor use.
Install Servomotor in an environment which meets the following conditions:
Free from corrosive and explosive gases
Well-ventilated and free from dust and moisture
Ambient temperature of 0 to 40°C
Relative humidity of 20% to 80% (non-condensing)
Inspection and cleaning can be performed easily
If the Servomotor is used in a location subject to water or oil mist, install a shield cover over the Servomotor.
Power supply voltage: three-phase ac200v serial encoder: 17 bit relative value. Design sequence: a. Shaft end: straight shaft without key.
Option: no brake oil seal.
High speed feed series: occasions where high-speed operation is required without load. The power supply of the main circuit and the control circuit are completely separated. When giving an alarm, only the power supply of the main circuit can be turned off, which is easy to maintain. Built in parameter setter.
Parameters can be directly input by the servo driver body. Save wiring
Serial encoder is adopted, and the number of encoder wiring is reduced by 1/2 compared with the original product
Multi in one control: torque, position and speed control can be used instead of parameter switching. Other performance descriptions of Yaskawa sgmgh-55aca21:
