Cruise control two-way digital PWM 4 Quadrant for DC motors from 5A up to 800A

AC power supply, single-phase and three-phase: 230 to 460Vac 50/60Hz.

DC power supply: 20 to 200Vdc / 200 to 650Vdc.


ROWAN ELETTRONICA complete the current production of analog drives intended to control DC motors, with a new set of more sophisticated fully digital drives that maximizes the potential ' of the DC motor speed controlling ' and torque in all 4 quadrants of the operation. The control system in IGBT with high PWM frequencies, compared to the control with SCR to the mains frequency, allows an excellent dynamic response and a moderate current ripple that avoids the downgrading of the motor applied .

This controller has the ability to select 3 types of speed control:

  1. Open loop with slip compensation;
  2. Closed loop with tachometer;
  3. Closed loop encoder with line driver;

Each drive is equipped with the basic function of the speed-torque control plus a specialized application:

C600A / C600F drive with CNC functions for controlling the position
C600R drive with PI controller functions
C600W drive with functions of winding / unwinding
C600S PWM power supply DC

All devices in the 600 series are equipped with a standard serial port RS485 isolation:

Standard: MODBUS
