Classification of the Lenze EVS9300 series in practice

The EVS9300 series is one of the well-known Lenze servo inverters for demanding applications with precise speed and torque control. Three points in particular are crucial in everyday service: quickly assigning the correct model, checking the relevant control connections and reliably evaluating fault messages.

Especially with older existing systems, there is often only nameplate data, individual error messages or incomplete documents. This makes it all the more important to have a compact technical overview that allows you to quickly classify the size, typical causes of errors and the appropriate next steps.

Anyone looking for Lenze EVS9300 error codes, Lenze EVS9300 technical data or Lenze 9300 terminal assignment will find the most important information in a structured form here.

Technical core data of the EVS9300 series

In practice, the initial classification requires network data, power range, interfaces, encoder evaluation and environmental conditions. This basic data helps to correctly assign devices and exclude obvious sources of error early on.

Rated voltage	3 × 400 V AC ±10 %, 50/60 Hz
Performance range	0,37–75 kW
Rules procedure	Field-oriented control (FOC), vector and U/f operation
Protection class	IP20
Ambient temperature	0–45 °C (up to 55 °C with derating)
Storage temperature	−25 to +60 °C
Interfaces	LECOM A/B (RS232/RS485), CAN, optional PROFIBUS-DP / INTERBUS-S
Donor evaluation	Resolver, Sin/Cos 1 Vpp, incremental encoder (HTL/TTL)
Brake control	24 V DC holding brake via integrated output

Model overview EVS9321 to EVS9330

Within the EVS9300 series, the devices differ primarily in terms of performance class and nominal current. This assignment is particularly important for exchange and procurement because in many cases there is initially only a rough performance specification or an incomplete type designation.

Where appropriate product pages are available, the individual models can be accessed directly from the table. This makes it easier to quickly get from the diagnosis to the appropriate replacement device.

model	Rated power (S1)	Maximum power (S6)	Rated current approx.
EVS9321	0,37 kW	0,55 kW	1,2 A
EVS9322	0,75 kW	1,1 kW	2,4 A
EVS9323	1,5 kW	2,2 kW	4,1 A
EVS9324	3,0 kW	4,0 kW	7,6 A
EVS9325	5,5 kW	7,5 kW	13,5 A
EVS9326	11 kW	15 kW	25 A
EVS9327	18,5 kW	22 kW	39 A
EVS9328	30 kW	37 kW	62 A
EVS9329	45 kW	55 kW	90 A
EVS9330	75 kW	75 kW	150 A

Terminal overview X5 – important control connections

When servicing is required, the terminal level is particularly relevant because many faults are not in the power section, but in releases, setpoint signals or external control circuits. In particular, the controller release and the clean separation of analog and digital reference potentials are among the typical test points.

Clamp	Designation	Function/Note
X5/1	+10 V Reference	Output, max. 4 mA – reference for potentiometer setpoint generator
X5/2	GND Analogue	Reference potential for analog signals
X5/3	Analog input E1	Speed setpoint, 0…±10 V, Ri ≈ 20 kΩ
X5/4	Analog input E2	Torque setpoint / additional setpoint, 0…±10 V
X5/28	REGLERFREIGABE	HIGH = 24 V = released, LOW = blocked
X5/A1	Digital output	Open collector, 24 V / 50 mA – freely parameterizable
X5/39–40	Fault relay	Changeover contact, 250 VAC / 1 A – opens in the event of a fault

Error codes and initial diagnostic measures

With EVS9300-Baureihe, the first correct classification of an error code often decides whether an operation is completed quickly or time is lost unnecessarily. The following overview therefore focuses on typical disruption patterns and the first sensible measure to take on site.

Note: Tip: After acknowledging an error, read out the error memory via C0168. The last four faults are stored there. This is particularly helpful if the original trigger is no longer active at the time of the test.

Code	Advertisement	Description	First measure
0011	OC1	Motor cable short circuit	Check motor cable and winding
0012	OC2	Ground fault in motor cable	Measure insulation resistance against PE
0015	OC5	I×t overload	Check cable length and ramp times
0016	OC6	I²×t overload	Check design and load peaks
1020	OU	Overvoltage DC link	Check brake resistor/brake unit
1030	LU	Undervoltage DC link	Check mains supply and contactors
0050	OH	Overtemperature heat sink	Clean fans, reduce load
–	CE	Fieldbus communication error	Check bus cable, connector, baud rate
–	Ph	Mains phase error	3 Check phases and fuses
–	SD	Speed deviation	Check mechanics, encoder, following errors

Spare parts, wear and replacement decision

Typical wear topics within the EVS9300-Reihe concern fans, intermediate circuit capacitors and, in the case of recurring short-circuit errors, also IGBT-modules. For economic decisions, it is important to distinguish between a correctable peripheral problem and an actual device defect.

Before replacing a power unit, parameters should always be backed up. It is equally important to compare the procurement with the exact type designation and the actual error pattern so that the size and design fit reliably.

Which error codes are particularly common with Lenze EVS9300?

Typical error patterns include OC1, OC2, OC5, OC6, OU, LU, OH, CE, PH and SD. In practice, the most common test areas are motor cables, mains supply, cooling, braking resistors, fieldbus and encoder technology.

How do I find the right model size of a EVS9300-Reglers?

The decisive factors are the type designation, nominal power, maximum power and nominal current. The most important devices in the series range from EVS9321 to EVS9330.

Which terminals are particularly important during the initial diagnosis?

The connections to X5 are particularly relevant for the EVS9300 series, including controller enable, analog inputs, analog ground and the fault relay.

What should you pay particular attention to when replacing a Lenze EVS9300?

What is important is the exact type designation, the appropriate power class, the rated current and the existing application. Before replacing, stored parameters and the actual cause of the error should be checked.
