Lenze E82EV551K2C 8200 vector Frequency Inverter 0.55 kW 230 V

8200 vector base controller for 0.55 kW on 230 V

Among the 8200 vector base controllers, the Lenze E82EV551K2C covers 0.55 kW (0.75 hp) with 1/N/PE or 3/PE 230 V mains. The range runs from 0.25 to 90 kW and is built from a base unit, a function module and optional accessories. As the 8200 vector now appears under previous products at Lenze, this inverter is a legacy type; the catalogue used here dates from 11/02, so check supply and revision with us first.

Technical specifications

Reading the type code E82EV551K2C

Using the catalogue type tables: E82EV is the 8200 vector base controller, 551 corresponds to the 0.55 kW motor rating, and K2C marks the 230 V mains class. Lenze appends three more digits to this stem. 0xx means integrated EMC filter and 2xx means none; make sure the suffix on your quote is the one you want.

Choosing and installing this size

The catalogue’s usual combination is E82ZAFSC010 for I/O and, if wanted, the EMZ9371BC keypad. Always compare the motor’s rated current with 3.0 A, because kW alone can mislead. Running at the highest chopper setting, 16 kHz, reduces the continuous rating to 2.0 A. A mains choke is optional here and lowers the single-phase mains current to 5.6 A. Hot or high sites need derating, which the catalogue puts at 2.5% per degree above +40 degrees C and 5% per 1000 m above 1000 m. Upright mounting is specified, with free space of at least 100 mm above and below.

Installation data from the catalogue: the motor cable may be 50 m shielded or 100 m unshielded at 8 kHz without extra output filters, subject to EMC conditions. The relay output switches 250 V AC at 3 A or 24 V DC at 2 A as a changeover contact, and an integrated brake transistor is included up to 11 kW, so only an external brake resistor is required for generator operation. Climatic class 3K3 to EN 50178, pollution degree 2 and vibration resistance up to 0.7 g (Germanischer Lloyd) are stated. A 0.55 kW drive stays within these limits.

What the function module adds

The 8200 vector base unit does not have control terminals of its own; the I/O, fieldbus or blank function module plugs into the front slot. The standard I/O module E82ZAFSC010 provides digital inputs, an analog input for a speed setpoint and an output, which is enough for local start/stop and potentiometer or 0–10 V speed control. Application I/O and fieldbus modules (for example PROFIBUS, CANopen or INTERBUS variants listed in the Lenze catalogue) are available where the inverter must be controlled from a PLC. When replacing a failed unit, the existing function module can usually be transferred to the new base controller, provided its revision is compatible.

Control modes

The 8200 vector supports V/f characteristic control, with linear or square-law curves for fans and pumps, and sensorless vector control, which gives better torque at low speed for conveyors, mixers and positioning tasks. Motor parameter identification is performed from the keypad or via Lenze engineering software, and the drive can be configured for a fixed-speed set or setpoint from an analog signal.

Maintenance and replacement advice

• Record all parameters, ideally with the EMZ9371BC keypad, which can store and transfer parameter sets, before a planned replacement.
• Check whether the existing unit has an integrated EMC filter (suffix 0xx) and order the same variant to keep the installation’s EMC behaviour unchanged.
• Electrolytic DC-link capacitors age over time; inverters stored without power for long periods should be reformed according to the manufacturer’s instructions before full load operation.
• Clean dust from the heat sink at regular intervals; the 50 W loss at rated current must be removed from the cabinet.

Using this inverter in the Gulf

Because the drive accepts single-phase 230 V, it is popular for small machines, workshop equipment and packaging units where only single-phase supply is available, while still running a standard three-phase 230 V motor. With 2.5% derating per degree above +40 °C, a control panel that reaches 50 °C in summer will reduce the continuous output current noticeably, so verify the motor current against the derated value or improve panel cooling. A motor connected in delta for 230 V must be used; a 400 V star-connected motor will not receive full voltage.

RFQ checklist

• Full type designation including the three-digit suffix.
• Function module and keypad required.
• Motor nameplate data and supply type (single or three phase).
• Acceptance of a current Lenze successor if this legacy type is unavailable.
• Quantity and delivery location.
