Quick Commissioning Of Siemens Micro Master VFD

Quick Commissioning Of Siemens MM Series

A variabl frequency drive a device which converts a fixed frequency, a fixed voltage sine wave power to a variable frequency,variable voltage which is used to control the speed of induction motors.Before come to the point quick commissioning of Siemens MM series let us see its advantages.

Advantages Of VFDs:

  • Controlled Starting Current
  • Power line disturbances reduced
  • Lower power demand on start
  • Controlled Acceleration
  • Adjustable operating speed
  • Adjustable torque limit
  • Controlled stopping
  • Energy savings

Synchronous speed(Ns)=120*F/P(No.Of Poles)

P0320 Motor magnetizing current
(this is entered as a % referred to P0305)
Motor magnetizing current as a % relative to P0305 (rated motor current).
With P0320 = 0, the motor magnetizing current is calculated using P0340 = 1 or
using P3900 = 1 – 3 (end of the quick commissioning) – and is displayed in
parameter r0331

P0640 Motor overload factor
(Motor overload factor in [%] relative to P0305)
This defines the limit of the maximum output current as a % of the rated motor
current (P0305). This parameter is set, using P0205 for constant torque, to
150 %, and for variable torque, to 110 %.
