RFQ / Lenze

Lenze's own manual puts it plainly: a controller of type E82EVxxx_2B must only be connected to a 240 V mains, because higher mains voltages damage the controller. That digit is the voltage class and it is the one to get right.

Lenze is on a great deal of European machinery in New Zealand, particularly materials handling, packaging and conveying. 8200, 8400, i550 and 9400 drives with Lenze geared motors.

Reading a Lenze type code

Take E82EV551K2C. Once the power notation makes sense, the whole 8200 range reads easily.

The power is written in exponent form

Three digits: two significant figures, then a multiplier, in watts.

So 152 is 1.5 kW, not 152 of anything. The last digit is the number of zeros.

That trips people up, because 222 and 152 look like they should be bigger than 751.

The voltage class digit

Lenze's warning is direct: a type E82EVxxx_2B must only be connected to a 240 V mains, and higher mains voltages damage the controller.

E82EV551K2C and E82EV551K4C are the same power on different supplies. One character.

Where the parameters live

Check this before ordering any Lenze drive, because it decides whether a replacement is a swap or a commissioning job.

The i550 memory module is the cheapest insurance on the range

Buy a spare memory module for each i550 on site and save the parameters to it.

It costs very little. With one, a drive failure is a mount, plug and go. Without one, it is a commissioning exercise with the line down.

On the older ranges there is no equivalent, so read the parameters off with the keypad or the E82ZBL-C diagnosis terminal while the drive still runs.

The notation changed between generations

So an 8200 parameter list does not map onto an i550. Replacing an older drive with a current one is a re-parameterisation, not a transfer.

That is the main argument for a like-for-like legacy drive, and it is what we are set up to supply.

A drive number alone does not describe an installation

True across the whole range, for different reasons by generation.

Function modules carry their own nameplate on the carrier housing, and Lenze instructs that you state the exact designation when seeking service.

The modules usually transfer to a replacement drive, which makes the repair cheaper than it first looks. But a bare drive will not do the job the old one did.

Safety: the discharge time is printed on the device

Worth its own section because Lenze handles it differently from most manufacturers.

All power terminals remain live for some minutes after mains disconnection. Lenze does not publish one figure for the range; instead, the time is given below the warning symbol on the device itself.

Isolating the supply does not make the drive safe. The figure varies by unit, which is exactly why it is printed on each one.

High leakage current

Lenze specifies fixed installation and a PE connection in accordance with EN 61800-5-1, and for a three-phase i550 connection an earth-leakage circuit breaker of 300 mA or greater, type B.

So an RCD that keeps tripping on a drive circuit, or one that never trips, may simply be the wrong type. That is a design matter for your electrician, but it is worth knowing the manufacturer specifies it.

The safety variants

Both generations put safety in something separate, and both are easy to miss.

A standard drive of the same power cannot perform the safety function. On the 8200 it physically lacks the terminal; on the i550 it lacks the module.

Whether a substitution is valid belongs with whoever holds the machine's safety assessment. We supply what you specify.

An STO fault is not a drive fault

Worth stating plainly because it gets drives replaced unnecessarily.

A Drive STO fault on an i550 means Safe Torque Off has been activated. The drive has disabled itself and removed torque, which is what it is supposed to do.

Check the STO inputs are correctly wired and active. Look at the safety chain and the E-stop before the drive.

The drive families

The 8400 lines are a hierarchy

The line is part of the specification, not a trim level. A StateLine will not run a TopLine application, so match the line as well as the power.

motec and protec are decentralised

If a machine has motors and no drives in the cabinet, this is why.

A motec inverter is mounted directly onto the motor, and protec units mount in the field.

So the drive is out on the machine, in the machine environment. Ingress, vibration and ambient heat matter far more than in a cabinet, and a failure is often a drive-and-motor job.

Coated variants

Worth checking on any machine in a wet, corrosive or condensing environment.

A varnished unit looks the same from the outside. If the existing drive is coated and the replacement is not, it will work and it will not last as long in that environment.

The geared motor matters

Worth flagging because Lenze is a drive and gearbox house, not just a drive house.

Lenze documentation repeatedly notes that when a controller is used with Lenze motors or geared motors, the drive instructions are only valid together with the motor instructions.

So on a Lenze installation the drive, motor and gearbox were specified as a system. A replacement drive of the right power is not automatically the right drive for that motor.

Send us the motor and gearbox nameplate as well as the drive.

Motor types supported

A reluctance or PM synchronous motor cannot be run by a drive parameterised for an induction motor. If the machine has one, the drive selection and its parameter set are not free choices.

Before ordering a replacement

What Lenze makes

A UL note

Relevant on machinery built for or exported to North America.

Lenze ships the drive with a sticker reading suitable for use on a circuit capable of delivering not more than, to be applied before mounting where the drive goes into a UL system.

Lenze specifies positioning it so that it covers no ventilation opening and no cooling fins.

How to give us what we need

The full type code off the nameplate. Power, voltage class and variant are all in it.

The function module designation, from its own nameplate on the carrier housing.

The communication module, if one is fitted.

The motor and gearbox nameplate, since Lenze specifies them as a system.

Whether you have the parameter set or the i550 memory module.

A photo. Lenze nameplates are usually legible and carry everything we need.

What we can supply

Current production. i550 and i510, 8400 across the lines, 9400 servo, i700 and i950, Lenze motors and geared motors, memory and safety modules, function and communication modules, keypads and accessories. Quoted with a delivered lead time.

Discontinued. 8200 vector and motec, earlier 82xx and 93xx ranges. Surplus and tested used, which keeps an existing machine on its original parameter set.

Modules separately. Often the actual fault, and always cheaper than a drive.

We buy Lenze

Lenze drives hold real value, particularly the 8200 range that plants still run and cannot buy new.

Keep modules with their drives. Function, communication, memory and safety modules all add considerably to what a unit is worth, and orphaned modules are worth having too. See Sell To Us.

Common questions

Can you get a part that is not listed on your site?
Usually. The site shows what we hold, not what we can source.

What does 152 mean in the type code?
1.5 kW. Two significant digits and a multiplier, in watts.

Can I use a 2 where a 4 was?
No. The digit is the mains voltage class and a 240 V unit on a 400 V supply is destroyed.

Do I need the function module too?
Usually it moves across from the old drive. Tell us what is fitted and we will confirm.

Why is my i550 showing an STO fault?
Safe Torque Off has been activated. Check the safety circuit and the STO wiring.

Do you supply used equipment?
Yes, where new is not available, tested and clearly described.

What is the lead time?
Ex stock items ship the next working day within New Zealand. We give you a firm lead time with the quote.

Do you quote in NZD?
Yes, in NZD including GST for New Zealand customers.
