Configuration and parameter settings, fault codes, and communication options are described for proper commissioning and troubleshooting.
| Single‑phase supply voltage | 200–240 V, 50/60 Hz |
|---|---|
| Three‑phase supply voltage | 200–240 V, 50/60 Hz |
| Switching frequency range | 2 kHz – 16 kHz |
| Maximum ambient temperature for ratings | 50 °C |
| Maximum current at 200 V (H018M2) | 4.8 A |
| Dimensions (Size 1) | 72 mm × 145 mm × 120 mm |
| Minimum front free space for cooling | 10 mm |
A minimum of 10 mm of free space in front of the unit is required to allow airflow.
When IP20 protection is adequate, the protective cover on the top of the drive should be removed.
The drive reduces the switching frequency when it exceeds 4 kHz.
