Frequently Asked Questions

What are the main control modes of the EM700?
The EM700 series supports both V/F Control (VVF) and Speed Sensorless Vector Control (SVC) for versatile motor management.
Does this inverter require derating at high temperatures?
It can operate at an ambient temperature of up to 50ºC without derating. For temperatures between 50ºC and 60ºC, a derating of 3% per 1ºC is required.
Is the EM700 suitable for compact control cabinets?
Yes, its compact size and support for side-by-side installation make it ideal for space-constrained environments.
What protection features are included?
It includes comprehensive protection against short circuits, overcurrent, overvoltage, undervoltage, phase loss, overload, and overheating.
What is the frequency output range?
The standard frequency control range is 0.00Hz to 600.00Hz, with high-frequency versions capable of reaching up to 3000.0Hz.
