Installation Notes
- Verify the drive type (MMV220/3, 2.2 kW) and supply voltage against the nameplate before installation.
- Mount the drive on a vertical wall/panel with adequate cooling clearance; observe ambient limit 0–50 °C.
- Size input fuses and check motor cable lengths per the MICROMASTER Vector operating instructions.
- Wire motor (U/V/W), control terminals (digital/analog inputs, relay outputs, RS-485) per the manual; use shielded control cable.
- After power-up, set motor parameters and control mode via the parameter set; perform a jog test before normal operation.
