MidiDrive A Characteristics of the MidiDrive 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 3 × 400 V / 3 × 480 V three-phase mains (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)
