RTA SRL
CSD J4 model is fitted into a metallic box of 90 x 99 x 30 mm. It is equipped with plug-in connectors, separated for power and logic sections. It is able to drive motors up to 4.4 Amps nominal current and it is the perfect choice for low-power applications needing a programmable motion controller. A dedicated input allows setting motor speed by means of analog signal (0-5 VDC; 0-10 VDC).
RTA’s CSD series features low power bipolar ministep drives. It is based on 2 families with different possibilities of command and interface.They are characterized by a limited power range, small dimensions and easy setup. CSD series drives provide the traditional high quality and reliability of RTA, but also a very competitive price. All models are equipped with Chopper systems featuring high performance Mosfet power stage, microstepping up to 3.200 step/rev for Step&Direction models and up to 4.000 step/rev for Programmable models.
* Version: drive housed in a metallic box 90 x 99 x 30 mm, equipped with plug-in connectors.* Range of operating voltages: 24-48 VDC.
* Range of current: 2.6-4.4 Amp. Setting up to four possible values by means of a serial line.
* Microstepping: 400, 800, 1.600, 3.200 and 500, 1.000, 2.000, 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.
* Possibility to set Pull-UP or Pull-Down inputs.
* Warranty: 24 months.
* 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.
* Communication through RS485 serial line; up to 48 can be connected on a single serial line. One instruction can be broadcasted to all drives.
* 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.
* Possibility to control the execution of 8 previously stored motion programs through hardware inputs. Accordingly, the drive can be used in stand-alone applications, without serial connection.
* 8 inputs and 3 outputs, all optically insulated. Among them 1 inputs and 1 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.
