RTA - PLUS J5 - Boxed, Stepping Motor Drive

Stepping motor drive boxed PLUS J5
( 28 - 62 VDC 4.4 - 8.0 Amp )

Introduction

  • Series of ministep bipolar chopper drives with an on-board programmable motion controller that can be used:
    - for the interfacing, through RS485 serial line, with a central control systeM
    - as an independent unit.
  • Presence of a dedicated analog input for the setting of motor target speed.
  • Target: medium power applications needing AC power supply and a programmable motion controller.

HIGHLIGHTS

  • Microstepping function up to 4.000 step/rev.
  • Setting of the motor target speed sampled at the beginning of the motion sequence (before motor starts running).
  • Programmable motion controller allowing connection up to 48 drives on a single serial line.
  • External fans not needed: ideal both for mounting inside a metallic electrical cabinet and for stand-alone applications.

Technical Specifications

  • Version: drive housed in a metallic box 152 x 129 x 46 mm, equipped with plug-in connectors.
  • Range of operating voltages: 28-62 VAC.
  • Range of current: 4.4-8 Amp. Setting up to four possible values by means of a serial line.
  • Microstepping: 400, 500, 800, 1.000, 1.600, 2.000, 3.200 and 4.000 steps/revolution. Setting by means of a serial line.
  • Automatic current reduction at motor standstill.
  • Protections:
    - Protection against under-voltage and over-voltage.
    - Protection against a short-circuit at motor outputs.
    - Overtemperature protection with thermal sensor.
  • Electronic damping facility for further acoustic noise and mechanic vibrations reduction.
  • Optoinsulated inputs.
  • External fans not needed.
  • Warranty: 24 months.

ANALOG INPUT TO CONTROL MOTOR SPEED

  • Target speed setting by means of analog input sampled at the beginning of the motion sequence (before motor starts running).
  • Input setting: 0-5 VDC or 0-10 VDC
  • Frequency range:
    - 3000 Hz - 48000 Hz (with ramp)
    - 0 Hz - 4100 Hz or 0 Hz - 510 Hz (without ramp)
  • Possibility of matching with potentiometers of 2.2 KOhm.

PROGRAMMABLE MOTION CONTROLLER FEATURES

  • Communication through RS485 serial line; up to 48 can be connected on a single serial line. One instruction can be broadcasted to all drives.
  • Possibility to control the execution of 16 previously stored motion programs through hardware inputs. Accordingly, the drive can be used in stand-alone applications, without serial connection.
  • Various type of available instructions, as for example: indexed run with ramp, free run with ramp, indexed run without ramp, run with a programmable braking distance, zero research. Space can be programmed in relative or absolute mode (linear or circular).
  • Number of steps for indexed ramp up to ± 8.338.607 in relative or absolute mode, speed from 1 to 24.000 Hz in standard resolution and from 1 to 48.000 Hz in high resolution, ramp times from 16 to 1440 msec.
  • Availability of instructions to developmotion programs as, for example: conditional jump time delay, program block and recovery, I/O management, FOR NEXT loop.
  • 11 inputs and 6 outputs, all optically insulated. Among them 3 inputs and 4 outputs are freely programmable.
  • Memory of 128 instructions kept also at drive switched-off and three run time instructions.
  • A utility working in Windows® is available in order to ease motion programs development by the user.
  • Alarm memory by use of yellow blinking led.
