• Voltage fluctuation ±10% or less
• Voltage imbalance ±3% or less
• Frequency variation ±4% or less
• Voltage distortion THD = 10% or less
• Use a filter designed for X200 inverter.
• Shielded wire (screened cable) is required for motor wiring, and the length must
be less than 5 meters.
• The carrier frequency setting must be less than 5 kHz to satisfy EMC
requirements.
• Separate the power input and motor wiring from the signal/process circuit
wiring.
• Ambient temperature: –10 to 40 °C
• Humidity: 20 to 90% RH (non-condensing)
• Vibration: 5.9 m/sec2 (0.6 G) 10 ~ 55Hz
• Location: 1000 meters or less altitude, indoors (no corrosive gas or dust)
