DC motor drive DCREG

analogdigital2-quadrant

The DCREG devices are fully digital control AC/DC converters supplying DC motors armature circuit and field circuit to obtain speed control or torque control, featuring 4-quadrant operation for DCREG4, or 2-quadrant operation for DCREG2. Te DCREG, the thyristor converter by Santerno, may be used to power supply high inductive loads, such as electromagnets. The application issues due to this type of load have been fixed by a control algorithm specifically developed for DCREG4 converters Maine features – Integrated digital potentiometer – Local control via keypad – Insensitivity to phase sequence (easier connection to the plant) – Independent power supply between the control section and the power section – N.8 programmable inputs – Double encoder input – N.5 programmable relay outputs – Auxiliary voltages 24Vdc, ±10Vdc, 5Vdc – N.1 speed analog output ±10Vdc – N.1 current analog output ±10Vdc – EMC compliance EN61800-3 ed. 2 second environment, category C3, EN55011 gr.2 class A – Certification: CE, EAC and UL (up to model DCREGX.350) – Compatible with the “REMOTE DRIVE” software for the remote control of the device Functions – Tacho generator, encoder, armature feedback – Automatic switching of the armature feedback in case of tacho/encoder failure (greater operation safety) – Current and speed autotuning (reduces fault occurrence and the installation time) – Field autotuning (reduces fault occurrence and the installation time) – Integrated field converter (operation at constant torque or constant power) – Field current saving (reduces field current when the motor is stopped) – Field boost (increases motor starting torque)
