Lenze 8200 Vector Selection

LL type (low leakage current): leakage current<3.5 mA, suitable for non fixed installation systems, limited to 230V single-phase and motor cable ≤ 5 m.

SD type (short distance): low leakage current, can be used for 30 mA leakage protection switches, supports motor cables up to 20 meters long.

LD type (long distance): used in situations where long motor cables are required and meet A/B level limits, with a motor filter that can reach up to 200 meters.

In addition, models above 15 kW can use integrated power filters (Mains filter A/B), which integrate incoming reactors and RFI filtering functions to simplify wiring.

4.3 Braking unit and braking resistor

Integrated braking transistors cover models ranging from 0.25 to 11 kW, and external braking resistors can achieve energy efficient braking. Low power braking resistors such as ERBM470R100W (470 Ω, 100W) are suitable for 0.55 kW 400V frequency converters; High power requires the use of ERBD series grid resistors (such as ERBD047R01K2) and external brake chopper EMB9352-E (suitable for 15~90 kW).

When multiple frequency converters share a DC bus, DC fuses (such as EFSGRxxxxAYHN) and DC bus bars (EWZ0036/EWZ0037) must be used to provide short-circuit protection.

4.4 Motor Filter

When the motor cable exceeds 50 meters (shielded) or 100 meters (unshielded), or the motor insulation is not suitable for supplying power to the frequency converter, a motor filter (such as E82ZM2223B) should be used. The motor filter can limit du/dt ≤ 500 V/μ s and limit the motor terminal overvoltage to below 1 kV to protect the motor winding.

4.5 Operation and Parameterization Tools

Keypad XT (EMZ9371BC): Text display, menu structure, parameter copying function, can be installed on control cabinet doors or handheld.

Global Drive Control easy (GDC easy): A free PC software for parameter settings, diagnostics, and file management, supporting serial or CAN adapter connections.

I/O and Communication Module Configuration

The 8200 vector provides two expansion slots (three slots for models above 15 kW), which can be combined with functional modules and communication modules.

5.1 Standard I/O PT (E82ZAFSC010)

Provide 1 analog input (0-10V, 0-20mA, 4-20mA, ± 10V), 1 analog output (0-10V), 4 digital inputs, 1 digital output, and 1 relay output. Suitable for basic speed regulation and start stop control.

5.2 Application I/O PT (E82ZAFAC010)

Provide 2 analog inputs, 2 analog outputs, 6 digital inputs, 2 digital outputs, and 1 frequency output (0~100 kHz single/dual channels), which can be connected to an incremental encoder to achieve closed-loop speed control.

5.3 Fieldbus module

CAN PT (E82ZAFCC010): CANopen protocol, supports master/slave, up to 500 kbit/s.

PROFIBUS-DP PT (E82ZAFC010): DP slave, automatic baud rate detection, maximum 12 Mbit/s.

INTERBUS PT (E82ZAFIC010): Remote bus slave station, 500 kbit/s.

LECOM-B PT (E82ZALC010): RS485, Lenze proprietary protocol.

AS Interface PT (E82ZAFFC010): AS-i bus used for simple digital signals.

The communication module (such as EMF2133IB PROFIBUS, EMF2175IB CANopen/DeviceNet) can be inserted into the top slot of the frequency converter and used in combination with functional modules.

Special installation techniques

6.1 Cold plate technology

Suitable for high protection level control cabinets above IP54 or in situations with water/oil cooling conditions. The frequency converter does not come with heat sinks and is directly installed on the cooling body provided by the user through a heat-conducting plate. The ordering model starts with E82CV. It is necessary to ensure that the contact surface is flat (deviation ≤ 0.05 mm) and the thermal resistance (Rth) meets the requirements (e.g. Rth ≤ 0.13 K/W for 11 kW models).

6.2 Push through Technology

Install the heat sink of the frequency converter outside the control cabinet, and there is almost no heat accumulation inside the cabinet. Suitable for applications with high heat generation and sensitive cabinet environment. The ordering model starts with E82DV. Randomly provide seals and installation frames to achieve IP65 protection level.

6.3 Safe Stop Version

To meet the requirements of EN 954-1 control category 3 and EN 1037 for "prevention of accidental start-up", Lenze offers special versions with safety relays (model suffix 040 or 241). External 24V power supply to safety relay, cutting off the power supply of IGBT driven optocoupler. Compared with the external motor contactor scheme, this scheme reduces wiring, saves space, and does not interrupt the motor cable shielding.

6.4 IT System Version

Used for ungrounded power supply systems (IT systems) to prevent insulation monitoring devices from malfunctioning. The ordering model ends with B101 (such as E82EV153K4B101). This version has improved the insulation strength of the frequency converter and will not damage the equipment in the event of a single phase to ground fault.

Summary of Application Cases

7.1 Speed adjustment (potentiometer given)

Use standard I/O modules, connect 1k~10k potentiometers externally to terminals 7/8/9, and connect terminal 28 to the start switch. Acceleration/deceleration ramp time can be set.
