inverter is installed near a large power
supply system (1000kVA or more and
wiring distance within 10m)
Installation and wiring
To operate the inverter with high
performance for a long time, install the
inverter in a proper place in the correct
direction and with proper clearances.
Incorrect terminal wiring could result in
the equipment damage.
To motor
Do not connect a power factor capacitor,
surge suppressor or radio noise filter to
the output side of the inverter.

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.

As the loads are heavier, the speed gap between rated RPM and synchronous speed
is widening (see the figure below). This function compensates for this inherent slip.
Set the Torque boost value within 2%. Setting it too high may cause motor overenergizing and lead to error in calculating slip speed.

When the input power is cut off due to instant power failure, the inverter
outputs Low voltage trip (LV) to hold the output.
When the power is restored, the inverter outputs the frequency before the
low voltage trip and the voltage is increased due to PI control.
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.
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.
Speed search is suitable operation when load inertia is large. It is highly
recommended to restart after stopping the motor when the load inertia is great.

This parameter sets the number of times auto restart is activated in H26.
It is used to prevent the system down caused by internal protection function activated by the
causes such as noise.
H26: Auto restart will become active after the H27. H26 – [Number of Auto restart try] is
reduced by 1 when it is active. If the trip outnumbers the preset restart try, auto restart
function is deactivated. If the setting is reset via the control terminal or the STOP/RST
key on the keypad, the number of auto restart try set by user is automatically entered.
If the trip does not occur for 30 sec after Auto restart operation, the H26 is restored to
the preset value.
When operation is stopped due to Low voltage {Lvt} or Emergency stop {EST}, Auto
restart will be deactivated.
After the H27- [Auto Restart time], the motor starts acceleration automatically via speed
search (H22-25).

The inverter turns off its output if the heat sink overheats due to a damaged cooling
fan or an alien substance in the cooling fan by detecting the temperature of the heat
sink.
The inverter turns off its output when it is time to replace the old DC link capacitor to a
new one.
The inverter turns off its output when the one or more of the output (U, V, W) phase is
open. The inverter detects the output current to check the phase loss of the output.
The inverter turns off its output if the DC voltage of the main circuit increases higher
than 400 V when the motor decelerates. This fault can also occur due to a surge
voltage generated at the power supply system.
The inverter turns off its output if the DC voltage is below 180V because insufficient
torque or overheating of the motor can occur when the input voltage of the inverter
drops.
The internal electronic thermal of the inverter determines the overheating of the
motor. If the motor is overloaded the inverter turns off the output. The inverter cannot
protect the motor when driving a motor having more than 4 poles or multi motors.

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.
