PLUS K4 model is based on a boxed hardware (152 x 129 x 46 mm) and is equipped with plug-in connectors, separated for power and logic sections. It is able to drive motors up to 6 Amps and it is the perfect choice for mid power applications needing an AC power input and a programmable motion controller.

RTA’s PLUS series features medium-high power bipolar ministep drives. It is based on 5 families with different possibilities of command, interface and power input. All models are equipped with Chopper systems featuring high performance Mosfet power stages, microstepping up to 4.000 step/rev. and power input in AC (PLUS B, K, J, E, L) or DC (PLUS A). PLUS E and PLUS L series have to be used in coupling with EM series stepper motors from RTA, equipped with encoders that are able to detect loss of synchronism of the motors.


* Version: drive housed in a metallic box 152 x 129 x 46 mm, equipped with plug-in connectors.
* Range of operating voltages: 55-100 VAC.
* Range of current: 3.6-6 Amps. 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.

* 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 or increased resolution, ramp times from 16 to 1440 msec.
* Availability of instructions to development 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.
