MidiDrive
MidiDrive servo drives are available for replacement needs only. Please see MidiDrive A for a current series of analog AC servo drives with similar power.
Characteristics of the MidiDrive Servo Drives
- Analog servo drives for AC servo motors
- Particularly suitable for applications with higher-level controllers (CNC)
- Two designs: Compact drives for control cabinet installation, complete with built-in power supply, or 19" plug-in module (chassis available as required)
- Mains connection to 3 × 400 V or 3 × 480 V three-phase mains (via isolating transformer)
- Design conforms to EMC requirements (CE marked), compliance with class A and B through RFI-filters (internal with compact drive, external with 19" plug-in module)
- 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 installation 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 2.4-times rated current
- No noise with switching frequency well above audible range
- Control supply voltage fed either by bus voltage or by 24 V DC
- 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
- Available also adapted to motors of other manufacturers
