Analog DCD1 servo drive (MAX output: 260 Vac / 50 A) with IGBT bridge. The ideal solution for driving direct current motors.
The DCD1 servo drive is ideal for driving permanent magnet or separately excited wound-field DC servomotors equipped with a speed transducer, with voltages up to 260 V and maximum currents up to 50 A.
The DCD1 features internal analogue circuits with an IGBT bridge and 4-quadrant operation with no deadband at zero speed: the motor shaft is rigidly held even at standstill.
Settings are adjusted using DIP switches, trimmers and test points; diagnostics are indicated by green and red LEDs.
Features
Versions
The DCD1 servo drive offers maximum flexibility for integration and rapid retrofitting of your industrial systems. The available versions span maximum output currents from 6 A to 50 A, with a maximum output voltage of 260 V. To ensure a seamless, plug-and-play retrofit of your equipment, you can request the specific version when ordering, specifying the pairing with your motor's transducer (5 V TTL line driver encoder or DC tacho-generator).
The DCD1 can also be configured as a DC power supply: contact us to find out more.
