RELIANCE UVZ701E AC Digital Servo Drive Inverter

RELIANCE UVZ701E AC Digital Servo Drive Inverter

OVERVIEW

The VZ7000 series drives having know-how and experience built up with the production of our VZ3000/BL3000 series servo drives are digital AC servo drives with the highest level of the latest technology in the drive industry. The VZ7000 series drives provide the most suitable solution for servo application and multi-axes synchronous application.

FEATURES

Wide Range of power

Applicable to a wide range of motor power from 1.5 kW to 600 kW.

High speed/High accuracy

Realize high speed frequency response of 1256 rad/sec or more by using high speed DSP and also improve stability at low speed by using high resolution encoders (1,000,000 pulses/rev).

Applicable to high speed synchronous communication

Perform high speed synchronous communication between the digital servo drive and the servo controller by using the SERCOS communication which conforms to the international standard IEC/EN61491 for digital communication.

Miniaturization and Space-Saving

Shrink the volume (of the drive) into 70% of conventional drives. Realize space-saving for the mounting space by employing the zero-stacking structure (firmly sticking structure).

Safety design

Design pays special attention to protective functions of each power element, built-in DC bus fuses, and independence of the control power from the power circuit.

Independent power supply to control circuits

Power of the control circuits is independent from the power of the power circuit. Thus, setting of parameters and display of the monitor can be confirmed when shutting off the power of the power circuit.

Isolation for regulator sections

Isolate all of regu lator sections from external input signa ls. Therefore, reduction of noise levels and safety for the regulator sections are much improved.

Numerous feedback options

Applicable to various feedback sensors such as high resolution encoders (1 ,000,000p/rev), serial absolute encoders, and incremental encoders.

Applicable to various field networks

Applicable to DeviceNet, CC-Link, and ControlNet Applicable to overseas codes and standards Conform to UL, cUL, and CE codes as standard models.
