Control Mode: IGBT PWM control, sinusoidal current drive method. For 220V and 380V, single - phase or three - phase full - wave rectification is adopted.
Encoder Feedback: 18 - bit multi - turn absolute encoder (can be used as an incremental encoder without a battery).
Operating/Storage Temperature<sup>[1]</sup>:
Operating/Storage Temperature: 0°C - 55°C. When the ambient temperature is between 45°C - 55°C, the average load rate should not exceed 80% (no icing); - 20°C - + 70°C.
Operating Humidity: Below 90% RH (no condensation).
Maximum altitude up to 2000m. No derating is required for use at 1000m and below. For every 100m increase in altitude above 1000m, the derating is 1%. If the altitude exceeds 2000m, please contact the manufacturer.
Note
[1] When installing the servo drive under the ambient temperature within this range. When stored in an electrical cabinet, the temperature inside the electrical cabinet should not exceed this range either.
Digital Input Signals - Input Signal Function Selection
