Lenze E94ASHE0034 9400 Servo Drive 0.75 kW 230/400/500 VAC

Lenze E94ASHE0034 – Multi-Voltage Drive for Precision Motion Control

The Lenze E94ASHE0034 belongs to the high-performance Series 9400. This drive accepts three different input voltages: 230 VAC, 400 VAC, or 500 VAC. All are three-phase at 50/60 Hz. Consequently, one part number works across multiple global power systems.

Rated output power is 0.75 kW. The drive delivers an output voltage from 0 up to the supplied line voltage. Output frequency ranges from 0 to 480 Hz, which suits both standard and high-speed motors.

Key Technical Parameters

Here are the critical electrical ratings for the E94ASHE0034:

• Input current: 3.3 A at 230 VAC / 3.5 A at 400 VAC / 3.1 A at 500 VAC

• Switching frequency: 8 kHz (fixed)

• Overload capacity: 150% for 60 seconds

• Braking chopper: Integrated internally

• Control modes: Speed, torque, and position

• Feedback support: Incremental encoder, resolver, absolute encoder

Additionally, the Lenze 9400 series includes high-precision current control loops. For this reason, the E94ASHE0034 performs well in dynamic applications like pick-and-place, winding, and indexing.

Mechanical and Environmental Specifications

The unit has an IP20 protection class. Therefore, it must be installed inside a control cabinet. Cooling uses forced ventilation with an internal fan. Key mechanical details:

• Dimensions: 90 x 250 x 195 mm (W x H x D)

• Weight: Approx. 2.9 kg net

• Operating temperature: 0°C to 40°C without derating

• Storage temperature: -25°C to +70°C

• Humidity: Max 95%, non-condensing

Furthermore, the drive complies with CE, UL, and cUL standards. This ensures safety for worldwide export.

Communication and Integration

The E94ASHE0034 supports multiple fieldbus options depending on the installed module. Common choices include:

• CANopen

• PROFIBUS DP

• EtherCAT

Meanwhile, the drive includes standard digital and analog I/Os. For instance, there are 4 digital inputs, 2 digital outputs, and 2 analog inputs. You can configure these for local interlocking without a PLC.

Installation Guidelines

First, mount the Lenze E94ASHE0034 vertically on a non-flammable surface. Use M4 screws in all four corners. Next, maintain 80 mm clearance above and below the unit. This allows proper airflow through the forced ventilation system.

For wiring, separate power cables from signal cables by at least 100 mm. Specifically, use shielded feedback cables with grounds connected at both ends. Moreover, install a mains filter upstream if other sensitive equipment shares the same supply.

Finally, perform the first startup without motor load. Use Lenze Engineer software or the integrated keypad. Set motor parameters based on the nameplate data. Then, run an autotuning cycle for optimal performance.

Typical Applications

The E94ASHE0034 handles many industrial tasks. For example:

• Small packaging machines

• Labeling units

• Conveyor synchronization

• Rotary tables

• Tension control systems

Because it supports three control modes, the same drive works for speed-controlled fans and position-controlled axes.

Packaging List

• Lenze E94ASHE0034 drive unit – 1 piece

• Control terminal connector (removable)

• Power terminal cover

• Quick start guide (multilingual)

• Safety warning sheet

Note: Fieldbus modules, feedback cables, and braking resistors are sold separately.

Frequently Asked Questions (FAQ)

1. Can the Lenze E94ASHE0034 run on single-phase power?
No. This drive requires three-phase input. Single-phase operation will cause undervoltage faults.

2. What software do I need to configure the E94ASHE0034?
Use Lenze Engineer (free download) or the optional keypad module. Both tools access all parameters.

3. Does the Series 9400 drive support safe torque off (STO)?
Yes, but only with an optional safety module. The base E94ASHE0034 does not include STO by default.

4. How do I reset an overload fault on the Lenze E94ASHE0034?
Wait for the drive to cool down. Then, cycle the 24 V DC control supply. Alternatively, send a reset command via fieldbus.

5. What is the maximum motor cable length for this drive?
Shielded cable: up to 25 meters. Unshielded cable: up to 50 meters. For longer runs, add an output reactor.
