• PID control function
Permits motor operation while controlling temperature, pressure, or flow rate without using an
external device such as a temperature regulator. Under the constant pump discharge pressure control,
the slow flowrate stop function is available.
Refer to Chapter 4, Section 4.8 "PID Frequency Command Generator" for details.
• Cooling fan ON/OFF control function
The inverter's cooling fan can be turned off while the fan or pump is stopped for noise reduction and
energy savings.
The ideal functions to serve a multiplicity of needs for small-capacity inverters
•
Compatible with a wide range of frequency settings
You can select the optimum frequency setting method that matches your machine or equipment via the
keypad (
/
keys or potentiometer), analog input (4 to 20 mA, 0 to 20 mA, 0 to +10 V, 0 to +5 V,
1 to 5 V), 16 multistep speed settings (0 to 15 steps) or via RS-485 communications.
• A transistor output is provided
This enables an overload early warning, lifetime forecast or other information signals to be output
during operation.
Refer to function code E20 in Chapter 9, Section 9.2.2 "E codes (Extension terminal functions)."
• High output frequency - up to 400 Hz
The inverter can be used with equipment such as centrifugal separators that require a high motor speed.
In this case, you need to check whether the machine operation in combination with the motor is
compatible or not.
• Three points can be set for a non-linear V/f pattern.
The addition of an extra point (total 3 points) for the non-linear V/f pattern, which can be set as desired,
improves the FRENIC-Mini's drive capability, because the V/f pattern can be adjusted to match a
wider application area.
Refer to Chapter 4, Section 4.7 "Drive Command Controller" for details.
Compact size
• Side-by-side mounting
More than one FRENIC-Mini inverter can be mounted side-by-side without any gap inside your
system control panel, thereby reducing the amount of space required for installation. (Ambient
temperature: 40°C (104°F) or lower)
Unit: mm (inch)
(Example: Inverters of 3-phase 200 V, 0.75 kW (1 HP) or less)
