West power inverter technology introduction

West power inverter is produced by Italy a high-performance drive, in the domestic first is by the west, the application of OTIS has unique superiority in matching synchronous motor: first of all, the drive function of PI is quite abundant, can be subdivided into four segments (including a zero speed PI), and the width is adjustable, so the match when the motor without teeth can not add to the load signal, start there will be no slip happens; Secondly it inside are two sets of self-tuning process sequence: one is the motor parameters self-tuning, it can automatically the whole set of motor and constant inductance and resistance, to avoid the due to motor manufacturers to provide parameter is not complete debugging difficulty increase; The other is a toothless positioning self-tuning, this program is to detect encoder and the position of the corresponding motor poles.
West power inverter main series:
1, AVY series
2, G - AGY series
3, AVS series
4, AVO series
West power inverter features:
- current regulator automatic tuning, magnetic field and the speed regulator, brushless motor magnetic field automatically phasing.
- of the frequency converter, motor and brake unit provide overload protection.
- the output voltage can be up to 98% of the input voltage
- the carrier frequency can be in 2, 4, 8, 12, 16 KHZ between choice.
- adjustable speed and torque current.
- through the option to extend card (EXP D8R4, EXP D14A4F) extensible analog/digital output and analog/digital input.
- can be of many different types of speed feedback device (encoder).
- space vector modulation mode to minimize noise.
30 - fault recorder can store the latest fault alarm and the corresponding failure time
- the standard device has three free configuration of analog input port.
- speed adaptive function.
- the alarm associated with speed.
