TrioDrive A
Characteristics of the TrioDrive A Servo Drives
- Analog servo drives for AC servo motors
- Compact devices for control cabinet installation, very compact design
- Particularly suitable for applications with higher-level controllers (CNC)
- Complete with built-in power supply for direct connection to 230 V AC (wide-range input)
- Design conforms to EMC requirements due to integrated line filters (CE marked), usable in First and Second Environment according to IEC 61800-3
- Easy wiring, since all connections can be plugged in at the front
- High performance with compact dimensions thanks to use of surface mounting devices (SMT) and latest power transistors (IGBTs)
- Easy commissioning due to adjustable gain, speed, and offset
- 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 or low power dissipation with reduced switching frequency (selectable)
- 24 V control supply voltage fed externally to retain position information in an emergency switch off
- Safe operation thanks to various protection and monitoring circuits
- Drive and motor protected by adjustable I²t current limiter
- Frequent switching off and on possible thanks to rapid discharge of the DC-bus voltage in case of mains switch off (function can be deactivated)
- Easy error diagnosis with LEDs for ready, overload, fault, and shunt
- Load and speed monitoring with current and speed monitor outputs
- Available also adapted to motors of other manufacturers
