When it is desired to avoid resonance attributable to the natural frequency of a mechanical system, these parameters allow resonant frequencies to be skipped. Three different areas of [Skip frequency High/Low limit] can be set with the skip frequencies set to either the top or bottom point of each area. However, during acceleration or deceleration, the run frequency within the set area is valid.

In the case of increasing frequency setting as shown above, if frequency set value

(Analog setting via voltage, current or digital setting via keypad) is within the range of

Skip frequency, it maintains Skip frequency low limit value. If the set value is outside the range, it increases the frequency.

In the case of decreasing frequency setting, if frequency set value (Analog setting via voltage, current or Digital setting via keypad) is within the range of Skip frequency, it maintains Skip frequency high limit value. If the set value is outside the range, it decreases the frequency.

When the input power is cut off due to instant power failure, the inverter outputs Low voltage trip (LV) to hold the output.

ƒ

When the power is restored, the inverter outputs the frequency before the low voltage trip and the voltage is increased due to PI control.

ƒ t1: If the rise in current is greater than the preset level in H23, the rise in voltage will stop and the frequency is decreased.

ƒ t2: If the opposite of t1 occurs, the increase in voltage starts again and the decrease in frequency stops.

When the frequency and voltage are restored back to the nominal level, acceleration will continue at the frequency before trip.

EMC INSTALLATION GUIDE

Cerus inverters are tested to meet Electromagnetic Compatibility (EMC) Directive 89/336/EEC and Low Voltage (LV)

Directive 73/23/EEC using a technical construction file. However, Conformity of the inverter with CE EMC requirements does not guarantee an entire machine installation complies with CE EMC requirements. Many factors can influence total machine installation compliance.

Essential Requirements for CE Compliance

Following conditions must be satisfied for the inverters to meet the CE EMC requirements.

1. CE compatible to this inverter

2. Installing inverter in an EMC enclosure

3. Grounding enclosure and shielded parts of wire

4. Using shielded cable

5. Use it under industrial environment.

6. It is important that all lead lengths are kept as short as possible and that incoming mains and outgoing motor cables are kept well separated.
