UnoDrive
Characteristics of the UnoDrive Servo Drives
- Analog servo drives for DC servo motors
- Particularly suitable for applications with higher-level controllers (CNC)
- 19" plug-in module design (3 height units, 8 width units, chassis available as required, installation in compact housing possible) or compact device for control cabinet installation
- Mains connection to 230 V AC, 3 × 400 V, or 3 × 480 V three-phase mains (each via isolating transformer)
- Design conforms to EMC requirements (CE marked), compliance with class A and B through external RFI-filters
- Easy wiring, since all connections can be plugged in at the front (BN 6540 to BN 6548) or conventional plug-in module wiring in case of connection from behind using indirect connectors (BN 6550 to BN 6558)
- High performance with compact dimensions thanks to use of surface mounting devices (SMT) and latest power transistors (MOSFETs)
- Easy commissioning due to adjustable feedback, speed, offset, and current limit
- No re-adjustment necessary when the drive is replaced thanks to plug-in customer module with all setting components
- Easily adapted to non-standard applications with plug-in option modules
- Rapid acceleration, deceleration, and reversing of servo motor by momentary current increase to double the rated current
- No noise with switching frequency well above audible range
- Control supply voltage fed by bus voltage
- Safe operation thanks to various protection and monitoring circuits
- Drive and motor protected by adjustable I²t current limiter
- Easy error diagnosis with LEDs for fault, ready, and overload
- Load and speed monitoring with current and speed monitor outputs
